Permits, Code & ADA Compliance — FAQs

Often yes, but a change of use — for example, retail to restaurant — usually triggers new code requirements for occupancy, fire protection, accessibility, parking, and ventilation, and requires permits and approvals. Costs depend on how far the existing space is from the new use's requirements. An early assessment is essential.

Rize Construction: Rize assesses change-of-use feasibility and cost up front, with a free, no-obligation estimate.

No. You generally cannot legally occupy or operate in a commercial space until it passes final inspection and receives a Certificate of Occupancy. Opening early risks fines, forced closure, and liability. Planning the schedule around inspection timing is essential to opening on the date you expect.

Rize Construction: Rize manages inspections and timing so you open on schedule, fully compliant — and can phase work to get you operating sooner.

Almost always, yes. Commercial remodels and tenant improvements typically require a building permit, plus trade permits for electrical, plumbing, and mechanical work. Even modest changes affecting walls, systems, or occupancy usually need permits and inspections. Cosmetic work like paint may not. Your local building department sets the requirements.

Rize Construction: Rize handles all required permitting under our license, so the responsibility and paperwork stay with us.

Often, yes. Renovations and tenant improvements can trigger requirements to bring affected areas — and sometimes the path of travel, restrooms, and entrances — up to current ADA standards. The extent depends on the work's scope and local rules. Planning for these upgrades early prevents budget and timeline surprises.

Rize Construction: Rize identifies ADA triggers up front so they're budgeted, not discovered mid-project.

Common ADA upgrades include accessible entrances and door hardware, compliant restrooms, accessible routes and ramps, proper parking with van-accessible spaces, signage, and clearances around fixtures. Which apply depends on your space, use, and the scope of work. An early accessibility review keeps these from becoming costly mid-project surprises.

Rize Construction: Rize reviews accessibility needs early and includes required upgrades in your free, no-obligation estimate.

Commercial construction follows the International Building Code as adopted and amended locally, plus electrical, plumbing, mechanical, fire, and energy codes, and ADA accessibility standards. Requirements vary by occupancy type and jurisdiction. A contractor familiar with your local codes ensures the project is designed and built to pass inspection.

Rize Construction: Rize builds to current local codes across the Denver-metro jurisdictions we serve.

Commercial spaces must meet fire and life-safety codes — which may require fire sprinklers, alarms, rated assemblies, proper emergency exits and egress, exit signage, and a fire-marshal inspection. Requirements depend on occupancy type, size, and use. Restaurants and assembly spaces often face stricter requirements due to higher occupancy and cooking hazards.

Rize Construction: Rize coordinates fire and life-safety compliance and the fire-marshal inspection as part of your project.

Unpermitted work can lead to fines, stop-work orders, forced removal or redoing of the work, denied occupancy, insurance and liability problems, and trouble selling or leasing later. It can also void warranties. Always confirm proper permits are pulled — it protects your investment, your business, and your legal standing.

Rize Construction: Rize always pulls the proper permits, so your project is fully compliant and protected.

Commercial projects require inspections at key stages — typically foundation, framing, electrical, plumbing, mechanical rough-in, fire and life safety, insulation, and a final inspection before occupancy. Each must pass before work continues. A final passing inspection leads to the Certificate of Occupancy, which you need before using the space.

Rize Construction: Rize schedules and manages all inspections through to your Certificate of Occupancy.

ADA compliance means a commercial space meets the Americans with Disabilities Act Standards for Accessible Design — accessible entrances, routes, restrooms, parking, signage, and clearances. Most commercial spaces serving the public must comply. New construction and many renovations must meet current ADA standards to pass inspection and avoid legal exposure.

Rize Construction: Rize builds to ADA standards and flags required accessibility upgrades early in your free estimate.

Occupancy classification is how the building code categorizes a space by its use — such as business, mercantile, assembly, factory, or storage. It determines the code requirements that apply, including exits, fire protection, accessibility, and allowable occupancy. Changing a space's use can change its classification and trigger new code requirements.

Rize Construction: Rize confirms your occupancy classification early so the project is designed to the right requirements from the start.

Plan review is when the local building department examines your construction drawings for code compliance before issuing a permit. Reviewers check structural, fire, accessibility, mechanical, electrical, and plumbing requirements. They may request corrections, which can require resubmittals. Complete, code-compliant plans move through review faster and avoid costly delays.

Rize Construction: Rize prepares thorough, code-ready submittals to keep plan review moving and minimize resubmittals.
