A deck built for a private home and one serving the public may look similar, but they do not necessarily follow the same rules. A restaurant patio or shared amenity space may need different structural capacity, exit routes, accessible features, and safety details. Understanding commercial deck building code requirements begins with identifying the building’s occupancy classification and the deck’s purpose. From there, the local building department can clarify which codes, amendments, permits, and inspections apply. This guide walks through the main factors that shape commercial deck design, explains why generic residential guidance can fall short, and offers practical steps for coordinating with designers, engineers, builders, and local officials.

Key Takeaways

Check local requirements first: Confirm the applicable codes, permits, and reviews with the building department before committing to a design.
Match the design to the project: Account for occupancy, accessibility, exits, structural loads, and site conditions with help from qualified professionals.
Keep the project team aligned: Share approved plans, engineering details, product documents, and inspection requirements with everyone involved before construction begins.

How Commercial Deck Codes Differ From Residential Codes

Commercial and residential decks may share basic components, but the rules for designing and approving them can differ. Requirements depend on the building’s occupancy, the deck’s intended use, how many people may use it, and the codes adopted by the local jurisdiction. A deck serving a restaurant, business, or shared community space may need different structural, accessibility, and life-safety provisions than a deck at a private home.

Classify Occupancy and Use

Begin by identifying the building’s occupancy classification and how people will use the deck. A private home deck is generally reviewed under residential provisions. A deck serving a business, multifamily property, or public venue may be subject to commercial building requirements. The local building department determines which classification applies, so confirm it before design work moves forward.

Describe the planned activities clearly. A space used for outdoor dining or events, for example, may have different design needs than one intended for occasional access. Commercial projects can face stricter requirements for structural capacity, accessibility, and safety features, as explained in TimberTech’s deck-code guide. Share the deck’s purpose with the designer and permitting officials early. The classification can influence structural plans, accessible routes, exits, and other details.

Assess Public Access, Occupant Load, and Egress

Public access and expected occupant load help determine what a deck must support and how people can leave it safely. A space that may hold many people at once needs to be designed for the loads associated with its use. The number, location, and arrangement of exits and stairs may also depend on the building’s occupancy and the deck’s connection to the rest of the property.

Consider how people will enter, move through, and exit the space, including during an emergency. Applicable accessibility rules may require an accessible route and other features. Egress requirements may also differ from those for a private residence. Don’t estimate capacity or exit needs based on a residential layout. Code violations can create safety risks and lead to costly corrections, as Grip-Rite’s overview of deck code requirements explains.

Explain Why Residential Standards May Not Apply

Residential deck guides can help explain common components, but they are not a complete design standard for a commercial project. Commercial decks may have different requirements for occupant loads, accessibility, exits, fire safety, and structural performance. The rules can also vary based on the deck’s height, materials, connection to the building, and local site conditions.

Requirements differ between jurisdictions, including across Colorado’s Front Range and foothills. A detail that works for a private home may not meet the standards for a business or shared space. Before settling on a design or ordering materials, verify which requirements apply to the specific property. DecksGo’s code guidance notes that requirements vary with location, design, materials, and environmental conditions, and advises checking with the local building authority before construction.

Confirm Governing Code Provisions

The authority having jurisdiction, typically a city or county building department, determines which code provisions and local amendments apply. Confirm the adopted code editions and project-specific requirements before finalizing plans. Don’t assume that a nearby community follows the same edition or that general online guidance reflects local rules.

Ask the permitting office which building, fire, accessibility, and zoning requirements apply. Also confirm whether the project requires plan review, professional engineering, or additional approvals. Keep the answers with the project documents so the owner, designer, engineer, and builder are working from the same information. Local requirements can vary by community, so check directly with officials, as Grip-Rite’s code overview recommends.

Which Codes and Permits Apply?

Commercial deck requirements depend on the project’s location, intended use, connection to an existing building, and site conditions. Before design work begins, contact the local building department to identify the authority having jurisdiction (AHJ) and confirm the review process. That early conversation can clarify which codes, permits, and supporting documents the project will need.

Check Local Building, Fire, and Accessibility Codes

A commercial deck may need to meet requirements for structural safety, fire protection, and accessibility. Which provisions apply depends on the building’s use, who can access the deck, and how it connects to the rest of the property. A deck serving a restaurant, for example, may be reviewed differently from one at an office or private facility.

Ask the AHJ which building, fire, and accessibility requirements apply to the proposed use. The department can tell you whether other reviewers need to be involved. General guidance is useful for preparing questions, but local rules determine what the project must meet. TimberTech’s deck code guide outlines how location, design, materials, and environmental conditions can affect requirements.

Confirm Code Editions and Amendments With the Authority Having Jurisdiction

Communities adopt specific editions of building codes and may amend them to address local needs. Similar projects in neighboring jurisdictions can therefore face different requirements. Confirm the adopted code editions and local amendments with the AHJ before finalizing drawings or submitting a permit application.

Ask whether the building department provides commercial plan checklists, design criteria, or standard details. These resources can help the project team prepare a complete submittal and anticipate review questions. The Grip-Rite guide to deck code updates also recommends checking with the local permitting office or inspector, since requirements depend on the code adopted by each community.

Identify Building, Zoning, Site, and Other Permits

A building permit may be only one approval the project needs. Zoning rules can affect a deck’s location, dimensions, and distance from property lines. Easements, covenants, utilities, drainage, and other site conditions may also limit where or how the deck can be built. Depending on the property and scope, additional reviews or permits may apply.

Before settling on a layout, ask the relevant local offices about setbacks, easements, and required zoning or site approvals. Don’t assume that a previous structure or paved area removes the need for review. DecksGo’s permit checklist advises confirming restrictions with local authorities, including whether approval or a variance is needed for work near an easement or setback.

Submit Plans, Engineering Documents, and Product Information

A permit application may require plans showing the deck’s dimensions, layout, building connections, stairs, guards, and placement on the site. The AHJ may also request structural calculations, engineered drawings, footing details, or information about materials and connectors. The exact submittal depends on the project and the local review process.

Request the building department’s current checklist before preparing documents. Plans should clearly describe the intended use and show how the design responds to site conditions and expected loads. Because structural sizing depends on factors such as materials, spacing, loads, and soil, have qualified design professionals prepare or review the required documents. DecksGo’s code guidance recommends confirming structural requirements with the local building authority.

What Structural Loads Must a Commercial Deck Support?

A commercial deck must be designed for its intended use, expected occupancy, and site conditions. The loads affect every part of the structure, from the footings to the connections, so they need to be established before plans are finalized. There is no single load value that applies to every commercial deck. The applicable building code, local amendments, and project design determine the requirements.

A qualified design professional can evaluate the site and specify the structural criteria. Share how the deck will be used and what features it will support, such as seating, planters, or built-in equipment. Confirm the design requirements with the local building department before construction begins.

Set Loads by Occupancy and Use

Start by identifying who will use the deck and what activities it will support. A restaurant deck with tables, chairs, staff, and groups of patrons has different demands from a deck intended for occasional maintenance access. The building’s occupancy classification and the deck’s specific use help determine applicable design loads and related requirements.

Occupant load and structural live load are connected, but they are not interchangeable. Occupant load estimates how many people may use an area for code and life-safety purposes. Structural live load accounts for people and other movable items the deck may need to support. Building codes set minimum safety standards, and the applicable rules can vary by jurisdiction. Review the potential consequences of code violations as part of planning, then confirm the requirements with local officials.

Account for Dead, Live, Snow, Wind, and Seismic Loads

A deck’s design must account for dead loads, which include the weight of the structure and fixed features, along with live loads from people, furniture, equipment, and other movable items. Depending on the location and design, environmental forces such as snow, wind, and seismic activity may also apply. The design professional determines which loads and combinations the structure must withstand.

A figure such as 50 pounds per square foot is sometimes cited as a general reference, but it should not be treated as a universal commercial-deck requirement. The correct value depends on occupancy, code provisions, local amendments, and site conditions. Use the deck code requirements checklist for general background, then have a qualified professional verify the criteria for the specific project.

Size Footings, Posts, Beams, Joists, and Connections for Site Conditions

Footings, posts, beams, joists, and connections work together to transfer loads safely to the ground. Their size, spacing, and attachment details depend on factors such as design loads, material properties, spans, and soil capacity. A structural layout that suits one property may not be appropriate for another, even when the decks appear similar.

Site conditions are especially important in Colorado, where slope, soil, exposure, and snow conditions can vary. Have a qualified design professional assess the site and specify the supporting structure. Avoid choosing components from a generic span chart without confirming that the chart applies to the project’s materials, loads, and conditions. The deck construction guidance on structural sizing also highlights the need to account for both loads and soil capacity.

Detail Ledger Attachments, Flashing, and Water Management

When a deck attaches to a building, the ledger connection must safely transfer loads to the structure. Plans should identify the fastening method, connectors, materials, and inspection details. The existing wall must be suitable for the connection. Do not assume that siding or other finish materials can provide structural support.

Flashing and water management help protect the connection and the building envelope from moisture. The design should show how flashing works with the wall’s weather-resistive barrier and directs water away from the ledger. Follow applicable code requirements and product instructions, and have the details reviewed before work begins. The guidance on ledger flashing offers a useful reminder to coordinate water management with the structural design.

Confirm Load Values and Engineering With Local Officials

Before plans are finalized, confirm the locally adopted code edition, amendments, and permit submittal requirements. The authority having jurisdiction, usually the local building department, can explain which load criteria apply and whether the project needs sealed engineering documents. Requirements can differ between cities and counties, so do not assume a value used on another project applies to yours.

Give the design professional and building department clear information about the deck’s intended use, site, and proposed features. Ask about project-specific review requirements early, so you can address questions before construction. Local officials determine which regulations apply, and the code guidance on confirming requirements with local authorities reinforces the value of checking before work starts.

What Do Codes Require for Guardrails, Stairs, and Accessibility?

Guardrails, stairs, and accessible routes help keep people safe on a commercial deck. The rules depend on the building’s occupancy classification, the deck’s purpose, how many people may use it, and the codes adopted by the local jurisdiction. A restaurant patio, shared apartment amenity, and private residential deck may have different requirements.

Residential deck guidance can help identify common safety considerations, but it is not a substitute for commercial code review. Commercial projects may have different guard heights, stair dimensions, accessibility requirements, and egress needs. The International Building Code is a model code used by many jurisdictions, but local adoption and amendments determine which provisions apply at a specific site.

Before selecting a railing or stair system, confirm the deck’s planned use and occupant load with the project’s design team. Then ask the local building department which code provisions apply and whether fire or accessibility reviews are required. Resolving these questions during design helps the team prepare permit documents that address safety, access, and inspection requirements.

Meet Guardrail Height, Strength, Opening, and Continuity Requirements

Commercial guardrails must meet code requirements for height, strength, openings, and placement. The rules depend on the adopted code and the deck’s use. Commercial projects may require taller guards than the 36-inch minimum often cited in residential guidance. Guardrails must also resist the loads specified by code, with posts and connections secured to the structure rather than attached only to deck boards.

Check opening limits between balusters, below the bottom rail, and around transitions. The applicable rules may depend on the location and use of the deck. Guards should protect exposed edges and continue where required, without gaps that could create a fall hazard. Review the design, connection details, and manufacturer’s product information before specifying a railing system. TimberTech’s deck code guide summarizes common residential guidance, but commercial plans should be checked against the governing local code.

Check Stair Width, Risers, Treads, Landings, and Handrails

Commercial stair dimensions must suit the adopted code and expected occupant load. Required width may depend on how many people the stairs serve and whether they form part of an exit route. Codes also set limits for riser height and tread depth, and they may restrict variation between steps in the same flight.

Include landings at the top and bottom of stairs, along with handrails and guards where required. Handrails and guardrails serve different purposes, so a design may need to meet separate rules for each. Consistent step dimensions help reduce trip risks and support a smooth inspection. Have the designer or engineer specify stair details on the plans, then confirm them with the building official before construction. Avoid relying on dimensions from a residential project, since commercial requirements may differ.

Provide Required Accessible Routes and Features

A commercial deck may need an accessible route connecting it to the building, parking, or other public areas. Depending on the site and applicable requirements, that route may use a ramp, lift, or another approved design. Stairs alone do not provide access for people who use wheelchairs or have difficulty climbing steps.

Accessibility can affect more than the path onto the deck. Requirements may apply to clear widths, door thresholds, turning areas, handrails, and access to seating or service areas. Review the 2010 ADA Standards for Accessible Design alongside state and local rules. Which provisions apply depends on the building, project scope, and site conditions. Include accessibility in early design discussions so the team can coordinate routes and features with the overall deck layout.

Address Egress, Lighting, Slip Resistance, and Fire Safety

Stairs and doors serving a commercial deck may be part of the building’s means of egress. The required number, location, and width of exits can depend on occupant load, travel distance, and building use. A dining patio or event space may need a different exit plan from a small employee-only platform. Coordinate egress details with the building and fire officials during design.

Lighting may be required along stairs and exit access, particularly where the deck is used after dark. Electrical work, including receptacles near the deck, must follow applicable electrical codes and may require GFCI protection. Surface selection also matters: ask the design team whether slip resistance or fire performance requirements apply to the project. Requirements vary by jurisdiction and use, so confirm them with the officials reviewing the plans instead of assuming one standard covers every deck.

Verify Local Requirements Instead of Relying on Residential Standards

Code requirements vary by jurisdiction, adopted code edition, local amendments, and building use. Online guides can help you identify questions, but some cover residential decks or cite provisions that are not in effect at your project location. Requirements may also depend on site conditions and the scope of work.

Ask the local building department which codes and amendments apply, and whether the project needs fire, accessibility, zoning, or electrical review. Share the intended use, estimated occupant load, drawings, and product specifications so reviewers can respond to the actual design. Colorado Custom Covers & Decks helps homeowners plan residential outdoor spaces, including design, engineered plans, permits, and construction. Commercial projects should likewise be coordinated with qualified design professionals and the local authorities responsible for plan review and inspection.

Which Materials and Fasteners Meet Commercial Deck Codes?

Material choices for a commercial deck depend on its intended use, structural design, exposure, and the codes adopted by the local jurisdiction. A product suitable for one project may not meet another project’s load, fire, accessibility, or durability requirements. Before ordering materials, have the design team confirm the specifications with the authority having jurisdiction (AHJ), the local building official responsible for code decisions.

Keep product data, installation instructions, and approval documents with the construction plans. These records help the project team verify that the materials installed match the approved design. They also make it easier to address questions during plan review and inspections.

Choose Structural Materials for Exposure and Use

Structural members such as posts, beams, joists, and stair stringers must meet applicable code requirements for their location and use. Depending on the design, that may mean pressure-treated lumber or a naturally durable species. Confirm the lumber’s grade, treatment, dimensions, and approved use. A general product description alone does not establish that it is suitable for a specific structural application.

Exposure matters, too. Rain, snow, ground contact, and moisture trapped near connections can affect a material’s service life. The engineer should specify products that suit the project’s loads and site conditions, and the builder should check that the materials match the approved plans. Grip-Rite’s deck code overview describes common material considerations, but the locally adopted code and project documents govern.

Follow Product Listings, Span Limits, and Installation Instructions

Composite and other manufactured decking products must be used within their approved limits and installed according to the manufacturer’s instructions. Check technical documents before setting joist spacing or choosing clips and screws. A board’s appearance does not show whether it can span the distance in a preliminary design. The decking, framing, and attachment system must work together and meet the project’s structural requirements.

Keep the product listing and installation guide available for plan review and construction. If a product is substituted, verify that it meets the same project requirements and update the plans when needed. Fastener type, spacing, and edge clearances can vary by product. TimberTech’s code and installation guidance explains why those details matter; follow the approved project documents and local requirements.

Specify Compatible, Corrosion-Resistant Connectors and Fasteners

Connectors and fasteners must be compatible with the framing material, decking, and any wood treatment. The wrong metal or coating can corrode, stain the deck, or weaken a connection. Specify hardware rated for the project’s exposure, then follow the connector manufacturer’s instructions for fastener type, size, and quantity. Do not replace a listed connector fastener with a generic screw unless the product documentation permits it.

Ledger connections need particular care because they transfer loads between the deck and the building. Bolts, lag screws, or anchors must match the engineered detail and applicable code. Requirements vary by project, so do not assume a general minimum size applies. Confirm the approved connection with the engineer and AHJ. DecksGo’s code guidance outlines common considerations, including corrosion-resistant hardware.

Confirm Fire Performance, Durability, and Surface Requirements

Check whether building or fire codes set requirements for decking materials. These may depend on the building, occupancy, location of the deck, or whether it serves an exit route. Ask the design team which product documentation is needed to demonstrate compliance. Where requirements apply to an assembly, confirm that the complete specified system meets them, not just the surface boards.

Choose materials for expected foot traffic, weather exposure, and maintenance needs. Also confirm any requirements for slip resistance, drainage, or changes in walking-surface level, particularly where accessibility standards apply. These details affect safe use as well as long-term upkeep. Codes set minimum requirements, so have the project team document how the selected materials meet the applicable standards before construction starts.

Protect Cut Ends, Connections, and Moisture-Prone Areas

Cutting or drilling treated lumber can expose areas that need additional protection. Follow the treatment supplier’s instructions for sealing cut ends and holes, and check that the product is compatible with the specified connectors and fasteners. Give extra attention to end grain, post bases, and places where water could collect. Proper drainage and clearances help reduce prolonged moisture exposure.

At the building, detail the ledger and flashing to direct water away from the structure. Select flashing that is compatible with the wall materials, ledger, and fasteners, then install it as shown in the approved plans. Corrosion-resistant flashing is commonly required where a ledger attaches to a wood-framed building, but the proper assembly depends on the project details. Have the designer and AHJ confirm the detail, and inspect the connection before covering it.

How Code Updates Affect Deck Construction

Code updates can affect a commercial deck’s design, permit documents, materials, and construction details. Because local requirements differ, confirm the rules for the project’s location before design or construction begins.

Check the Adopted Code Edition Before Design and Permit Submittal

The newest code edition is not automatically the one that applies to a project. Each city or county adopts its own edition and may set a different effective date. Before design begins, contact the building department where the deck will be built and confirm which codes and amendments apply to the building and its intended use.

Check again before submitting permit plans, particularly if the project has been in development for several months. This gives the design and engineering team time to update drawings, specifications, and material selections before they are finalized. Since code adoption varies by jurisdiction, general guidance should not replace confirmation from local officials.

Review Local Amendments and Building Department Notices

A city or county may amend a model code, publish interpretations, or issue notices that clarify how requirements apply. These local details may affect structural loads, fire separation, accessibility, inspections, or the documents required for a permit application. Review the building department’s website and ask whether local amendments, checklists, or plan-review policies apply to the project.

Keep a record of the code edition and guidance you receive, including when you received it and which department or official provided it. Share that information with the architect, engineer, and builder so everyone is working from the same requirements. Rules can differ between neighboring communities, so confirm current requirements with the local building authority rather than relying on another project’s plans.

Recheck Structural, Accessibility, Egress, and Fire-Safety Requirements

When a code changes, review the full plan, not only the detail that prompted the review. Updated structural criteria may affect footings, connections, dimensions, or material specifications. Accessibility requirements can change routes, clearances, and transitions, while egress and fire-safety provisions may affect how the deck connects to the building or serves occupants.

Ask the project’s design professional or engineer to identify relevant changes and document their effect on the plans. Make sure the permit set reflects those changes before construction starts. Missed requirements can create unsafe conditions or lead to redesign, repairs, fines, insurance complications, or resale difficulties. Reviewing current code requirements early gives the team more time to address safety and approval issues.

Avoid Generic or Outdated Guidance

Online articles and older project plans can explain common deck concepts, but they may refer to a different code edition, building type, or jurisdiction. Commercial decks may serve more occupants or public uses than residential decks, so residential dimensions and details may not satisfy the applicable rules. Treat general information as background, not as a project specification or proof of approval.

For project decisions, use the adopted code, guidance from the local building department, and advice from qualified design professionals. Check that manufacturer details and product information fit the project’s code edition and installation conditions. Deck requirements draw from broader building codes, and they vary by location. Local code confirmation helps the project team verify requirements before finalizing plans or starting work.

How Can Builders Prepare for Approval and Construction?

Preparation starts with understanding how the deck will be used, what conditions the site presents, and which local requirements apply. Commercial projects may involve public access, higher occupant loads, accessible routes, or connections to an existing building. These factors can shape the design, engineering, permits, materials, and inspection schedule.

Before plans are submitted, gather the information the project team needs to make sound decisions. Confirm the governing code edition and local amendments with the building department, then identify which permits and reviews apply. Requirements can vary by jurisdiction, so general guidance is a starting point, not a substitute for local direction. The deck code guidance from TimberTech also recommends checking with the local building authority before construction.

Keep the owner, designer, engineer, builder, and building official informed as the project develops. A shared record of decisions, approvals, product documents, and inspection results helps the team stay aligned from design through construction.

Gather Site Conditions, Existing Building Documents, and Use Details

Start with a site review and document the proposed deck’s location, dimensions, slope, drainage, soil conditions, nearby structures, and construction access. In Colorado, include relevant snow and wind conditions in the design discussion. These details help the design and engineering team create plans that reflect the actual site.

Gather existing building plans, surveys, prior permits, and information about the structure where the deck will attach. Also clarify how the space will be used, including expected occupant load, furniture or equipment, and access needs. A deck serving a restaurant or assembly area may face different requirements from a private deck. Since rules depend on location and project details, use deck code guidance as a reference, then confirm applicable requirements with the local building authority.

Coordinate the Owner, Designer, Engineer, Builder, and Building Official

Bring the project team together early. The owner can describe how the deck needs to function; the designer can shape those needs into a layout; and the engineer can address structural loads, connections, and foundations. The builder can identify construction access, material considerations, and details that may affect cost or scheduling.

Before finalizing plans, ask the building official what the permit submittal should include. Early conversations can clarify requirements for unusual occupancy, accessible routes, or attachments to existing structures. Agree on who will submit the plans, respond to review comments, and arrange inspections. Local rules and interpretations vary, so confirm details directly with the local permitting office rather than relying on general advice alone.

Allow Time for Reviews, Revisions, and Inspections

Include review time in the project schedule. The building department may request additional calculations, revised drawings, product information, or clarification about the deck’s use. Fire, zoning, site, and accessibility reviews may involve separate departments, so confirm which reviews apply and account for them before setting a construction start date.

Ask the building department which inspections are required and when they must take place. Depending on the project and jurisdiction, inspections may cover footings, framing, and completed work. Avoid covering work before a required inspection, since it may need to be exposed for review. Keep the owner updated on approval milestones, and begin construction only after the required permits are issued. Code violations can result in repairs, fines, removal requirements, or insurance and resale complications, as outlined in this deck code update overview.

Track Approvals, Inspection Sign-Offs, and Product Documents

Keep a project file with approved plans, engineering calculations, permits, inspection records, and written approvals. Include product information for decking, railings, connectors, fasteners, and other specified components. Product listings and installation instructions can help the team confirm that materials are being used as intended.

Record inspection dates, results, and any corrections requested by the building department. Before making a field change, check whether the engineer or building official needs to review it. A change to a span, member size, connection, or material can affect structural performance and may require revised plans. Since structural sizing depends on loads, materials, spacing, and soil conditions, compare project documents with local requirements and use reliable deck code checklists as a reference.

Resolve Code Questions With the Authority Having Jurisdiction Before Work Begins

Deck requirements come from provisions across building codes, and the adopted rules can differ by location. Before construction, confirm the applicable code edition, local amendments, permit conditions, and any requirements tied to occupancy, egress, fire safety, or accessibility.

When a plan detail or product requirement is unclear, send the building official a focused question along with the relevant drawing or product information. Keep written responses with the project documents and share them with the owner, designer, engineer, and construction crew. This gives everyone consistent direction and helps prevent work from proceeding based on assumptions. Checking with the authority having jurisdiction before work begins is more dependable than applying residential rules or generic online guidance to a commercial project.

Frequently Asked Questions

Can I use residential deck plans for a commercial project?
Not without having them reviewed. Commercial decks may have different requirements for occupancy, structural capacity, exits, guards, and accessibility. Ask a qualified design professional and your local building department to confirm what the project needs before adapting existing plans.

Who decides which codes apply to a commercial deck?
The authority having jurisdiction, usually the city or county building department, determines which adopted codes and local amendments apply. Contact that office with the deck’s location, intended use, and preliminary design details.

Does every commercial deck need engineered plans?
Not necessarily, but the building department may require engineering based on the deck’s size, design, loads, site conditions, or connection to an existing building. Check the permit submittal requirements before preparing plans.

What information should I have before applying for a permit?
Be ready to describe the deck’s location, dimensions, intended use, expected occupancy, and access needs. The permit office may also request site plans, structural drawings, calculations, and product specifications.

Do commercial decks need accessible routes and special exits?
They may. Accessibility and egress requirements depend on the building’s use, the deck’s connection to the building, and the number of people it serves. Confirm the applicable requirements with the building department and include them in the design from the start.
