Building Permit in Denver, Colorado (2026)
Without a Building Permit from the Denver Permitting Office, you cannot legally begin construction, renovation, or structural work on your restaurant—and your general contractor cannot pull other permits that depend on it. This requirement, also called a construction permit or building project authorization, is issued by the Denver Community Planning & Permitting Department and covers all structural, mechanical, and safety work.

Why You Need a Building Permit
The Building Permit in Denver is your legal gateway to construction, mandated by a layered set of codes you must follow. The primary authority is the International Building Code (IBC) 2021, as adopted and amended by the State of Colorado and enforced locally by the Denver Department of Community Planning and Development. Your project must also comply with the Denver Building and Fire Code, the Denver Zoning Code for use and dimensional standards, and the Colorado Accessibility Standards. These regulations are not suggestions; they are legally binding ordinances (like Denver Revised Municipal Code, Title 10) designed to ensure life safety, structural integrity, and public welfare.
Operating without this permit or failing inspections carries severe, immediate, and costly consequences:
- Stop-Work Orders & Fines: Inspectors can halt all activity on-site. Daily fines accrue until compliance is achieved, often ranging from hundreds to thousands of dollars depending on the violation's severity and duration.
- Certificate of Occupancy Denial (CO): The city will not issue a CO for new buildings or major changes of use. Without a CO, you cannot legally open your restaurant to the public or occupy the space.
- Required Demolition: The city can order the removal of non-compliant construction at your expense, erasing your investment and causing massive project delays.
- Insurance & Lease Voidance: Most commercial leases and property insurance policies explicitly exclude coverage for unpermitted work. A fire or accident in an unpermitted space could leave you fully liable for damages and breach your lease.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: As of 2026, Denver has fully integrated its electronic permit system for all commercial projects, requiring digital plan submission and enabling online permit issuance for eligible, smaller-scale work, which has reduced initial review timelines for standard tenant finishes.

17 of 20 auto-filledProject Description and Scope of Work
textEnter a concise but complete description of the construction work, such as 'Tenant finish-out for new restaurant, including interior non-load-bearing walls, plumbing for 3-compartment sink and restrooms, and new electrical service.'
COMMON MISTAKE: Using vague terms like 'remodel' or 'kitchen work' which lack specific trades and scopes, leading to review delays for clarification.
Building Square Footage
textEnter the total square footage of the building area being constructed or remodeled, which must match the dimensions on your architectural drawings and is used to calculate permit valuation.
COMMON MISTAKE: Entering the lot size or the restaurant's leased area instead of the actual construction area, causing a fee miscalculation and application rejection.
Construction Cost Estimate
textEnter the total estimated cost for all construction work, including materials and labor, which directly determines the Denver building permit fee; format as a whole number without commas (e.g., 125000).
COMMON MISTAKE: Underestimating to reduce permit fees or omitting contractor labor costs, which triggers an audit and can lead to stop-work orders if the valuation is found to be inaccurate.
Property Address Where Construction Will Occur
textEnter the complete, official street address of the property, which must exactly match the address on file with the Denver Assessor's Office for plan review routing.
COMMON MISTAKE: Using a nearby intersection, a P.O. Box, or an incorrect unit/suite number, which causes the application to fail address verification and halts review.
Zoning Classification of the Property
textEnter the property's zoning district code from the Denver Zoning Code (e.g., C-MX-5, I-MX-3, or RT-3), which you can find on the Denver Zoning Map or a recent property report.
COMMON MISTAKE: Guessing the zone or using an outdated classification, which results in an automatic rejection because the proposed use (restaurant) is not verified as permitted in that zone.
Proof of Property Ownership or Authorization
textIndicate the document you are submitting as proof, such as a 'Warranty Deed,' 'Title Report,' or a notarized 'Authorization Affidavit' from the property owner if you are a tenant.
COMMON MISTAKE: Listing an unrecorded contract or a business license instead of a recorded deed or proper affidavit, causing an immediate rejection for insufficient ownership verification.
Plot Plan Showing Property Boundaries
textIndicate that a scaled plot plan is attached, showing the property lines, existing structures, and the location of the proposed work relative to setbacks.
COMMON MISTAKE: Submitting a site plan without property lines drawn to scale or missing required setback dimensions, which fails the zoning compliance check.
Property Owner Name
textEnter the legal name of the property owner(s) as it appears on the recorded deed; for an LLC, use the full registered business name.
COMMON MISTAKE: Entering a property manager's name or a DBA instead of the legal entity on title, creating a discrepancy that delays approval until corrected.
Property Owner Contact Information
textEnter a current phone number and email address for the property owner, which the Denver Community Planning and Development department may use for official notifications.
COMMON MISTAKE: Providing contact info for the contractor or applicant instead of the owner, which can void notifications if the department cannot reach the responsible party.
Applicant Name
textEnter the full name of the person submitting the application, who is responsible for communication and must be either the owner, a licensed contractor, or an authorized agent.
COMMON MISTAKE: Leaving this blank or entering 'TBD,' which is not accepted as the applicant is the legally responsible point of contact for the permit.

Top 5 Building Permit Mistakes
1. Submitting Incomplete or Incorrect Property Information
Entering the wrong Assessor's Parcel Number (APN) or legal property description is the leading cause of application rejection in Denver. The Department of Community Planning and Development's (CPD) system cross-checks this data against county records; a mismatch triggers an immediate administrative return. This mistake typically adds 2–3 weeks to your timeline as you must correct the form and restart the review queue. Double-check the APN on your property deed or the Denver Property Information site before submitting.
2. Submitting Non-Conforming Construction Drawings
Sketching floor plans by hand or failing to include required details like structural calculations, energy code compliance, or life safety plans leads to a 'plan review correction' notice. Denver's 2022 International Building Code amendments require specific architectural and engineering stamps. Submitting non-professional drawings almost guarantees a 4–6 week delay for re-submission and a second review fee. Hire a licensed architect or engineer familiar with Denver CPD's digital submittal standards for drawings.
3. Incorrectly Calculating Valuation and Fees
Underestimating the project valuation to lower permit fees is a common audit trigger. Denver CPD uses standardized square-foot costs (e.g., $250/sq.ft. for Type III-B restaurant build-out) and will re-calculate. A discrepancy results in a fee correction notice, halting all plan review until the balance is paid, adding 1–2 weeks. Use the city's published valuation table and consult your contractor's detailed estimate to report accurate total project value.

See All RequirementsProcessing time varies depending on project complexity and whether the application is complete on initial submission, per the Denver Department of Community Planning & Development (CPD) website. Standard review typically ranges from 10–15 business days for straightforward projects, though complex renovations or additions requiring structural review can extend to 4–8 weeks. Incomplete applications will be returned for revision, which adds 2–3 weeks to your timeline — verify all required documents are included before submission to avoid delays.
Government filing fees for building permits in Denver vary based on project scope and valuation; contact the Denver Department of Community Planning & Development to confirm current fee schedules for your specific project type. Fees are calculated using the estimated construction cost and typically range from $100–$2,000+ for restaurant buildouts, per the CPD fee schedule. ApronPrep recommends contacting CPD directly at (720) 913-1311 or visiting their website to get an exact quote before submitting your application. Not legal advice — verify fees with the authority.
No — a building permit issued for one location cannot be transferred to a different address, per the Denver Building Code and CPD policy. If you are relocating your restaurant, you must apply for a new building permit for the new location and obtain a Certificate of Occupancy before operating at that address. Permits are site-specific and tied to the legal address and property details on the original application.
Building permits do not renew on a recurring basis — they are issued once for a specific project and remain valid for the life of the building modification, per Denver CPD policy. However, if your permit expires before the project is complete (typically 180 days from issuance for standard permits), you must request an extension in writing to CPD before expiration. Once your restaurant project is complete and inspected, you will then need to obtain a Certificate of Occupancy to legally operate, which is a separate requirement from the building permit.
After you submit a completed building permit application, a CPD inspector will schedule a site inspection to verify that all work complies with the Denver Building Code and your approved plans — typically 3–7 business days after submission, per the CPD inspection guide. The inspector will check structural integrity, electrical systems, plumbing, ventilation (critical for restaurant kitchens), and other relevant building systems for code compliance. If violations are found, you will receive a written notice detailing required corrections; you must address these and schedule a re-inspection (adding 1–2 weeks to your timeline). Once all inspections pass, CPD issues final approval, after which you can proceed to obtain your Certificate of Occupancy to open your restaurant.
