Mechanical/HVAC Permit in Denver, Colorado (2026)
Without a Mechanical/HVAC Permit, the Denver Building Department will not issue your Certificate of Occupancy—meaning you cannot legally open your restaurant, and your lender will not release funds. The Mechanical/HVAC Permit (also called a mechanical equipment permit) is issued by Denver Community Planning and Development (CPD) and certifies that your HVAC system, ventilation, and mechanical equipment comply with the Denver Building Code and International Mechanical Code. Key facts:
- 32 fields total — ApronPrep auto-fills 27
- $0–$0 government filing fees (contact Denver CPD for current fee structure, as fees vary by project scope and equipment classification)
- 5–15 business days typical processing time for permit review and approval

Why You Need a Mechanical/HVAC Permit
In Denver, the requirement for a Mechanical/HVAC permit is established by the 2021 International Mechanical Code as adopted by the State of Colorado, along with amendments in the Denver Building and Fire Code (Title 10 of the Denver Revised Municipal Code). This permit is administered locally by the Denver Community Planning and Development (CPD) Department. The code requires that any installation, alteration, repair, or replacement of heating, ventilation, air conditioning, refrigeration systems, or related ductwork must be reviewed and inspected to ensure systems are designed and installed for safety, energy efficiency, and proper ventilation.
Proceeding with mechanical work without this permit carries significant, immediate consequences. Based on Denver's enforcement protocols, the most common penalties include:
- Stop-Work Orders: Issued on-site, halting all construction and freezing your project timeline indefinitely.
- Daily Fines: Monetary penalties that accumulate for each day the unpermitted work exists or continues, adding major unexpected costs.
- Certificate of Occupancy Denial: The city will not issue a final C of O, preventing you from legally opening your restaurant to the public.
- Required Demolition: You may be forced to tear out and redo non-compliant work at your own expense to pass inspection.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: As of 2026, Denver CPD has fully transitioned its mechanical permit application and plan review process to its online ePermit portal, requiring all submissions to be digital.
Who Needs a Mechanical/HVAC Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required for all new installations, replacements, or major modifications to gas-fired kitchen equipment, exhaust hoods, and heating/cooling systems under Denver Building and Fire Code § 105. |
| Bar / Nightclub | Required | Required for HVAC systems serving occupant loads and any ventilation for kitchens or prep areas, mandated by Denver Building Code § 105.1 for mechanical work. |
| Food Truck | Not Required | Typically exempt; mechanical systems are part of the vehicle certification and regulated by the Colorado Department of Public Health and Environment for mobile units, not local building permits. |
| Coffee Shop / Café | Required | Required if installing or modifying any gas-powered equipment (e.g., espresso machines, boilers) or ducted HVAC systems, per Denver's permit thresholds for mechanical work. |

27 of 32 auto-filledRestaurant Legal Name
textEnter the exact legal business name registered with the Colorado Secretary of State, as it appears on your Articles of Organization or Incorporation.
COMMON MISTAKE: Using a DBA or 'doing business as' name instead of the registered legal entity name, which will cause Denver Community Planning & Development to reject the application for mismatched records.
Restaurant Address
textEnter the complete physical street address of the restaurant where the HVAC work will be performed, including suite or unit number if applicable.
COMMON MISTAKE: Omitting the suite/unit number in a multi-tenant building, which prevents inspectors from locating the correct site and delays permit issuance.
Primary Contact Name
textProvide the full name of the person authorized to manage the permit, typically the business owner, project manager, or a designated agent.
COMMON MISTAKE: Entering the name of a contractor who is not formally authorized to represent the business, which can void permit approvals.
Contact Title
textEnter the official title or role of the primary contact (e.g., Owner, Managing Member, Project Manager).
COMMON MISTAKE: Leaving this field blank or entering 'N/A,' which Denver reviewers may flag as incomplete information.
Contact Phone
textProvide a direct, working phone number for the primary contact, including area code, where they can be reached during business hours.
COMMON MISTAKE: Providing a phone number with an out-of-state area code without explanation, which can raise questions about local representation.
Contact Email
textEnter a valid, frequently monitored email address where all permit correspondence and inspection schedules from Denver will be sent.
COMMON MISTAKE: Using a generic or shared email address that may miss time-sensitive inspection notices, causing project delays.
Property Ownership Status
textSpecify whether the business owns the property or is a tenant, as this determines if additional landlord authorization is required.
COMMON MISTAKE: Incorrectly selecting 'Owner' when you are a tenant, which leads to immediate rejection for lacking the required landlord consent documentation.
Landlord Authorization Letter
textIf you are a tenant, confirm that a signed landlord authorization letter granting permission for the HVAC work is attached to the application.
COMMON MISTAKE: Failing to attach the signed letter or providing one without the landlord's notarized signature, which is a mandatory requirement per Denver's permit guidelines.
Installation Type
textDescribe the scope of work, such as 'New Installation,' 'Replacement,' 'Modification,' or 'Repair,' as defined by the Denver Building Code.
COMMON MISTAKE: Using vague terms like 'HVAC work' instead of the specific, code-defined installation type, which requires clarification and delays review.
HVAC System Type
textSpecify the mechanical system, such as 'Packaged Rooftop Unit,' 'Split System,' 'Furnace,' 'Boiler,' or 'Ductless Mini-Split.'
COMMON MISTAKE: Listing only the brand name instead of the system type, which prevents the reviewer from applying the correct code sections and triggers a request for information.

Top 5 Mechanical/HVAC Permit Mistakes
1. Incomplete Contractor & Equipment Information
Leaving fields blank for the licensed contractor's name, license number, or specific equipment model numbers causes immediate rejection by Denver's Community Planning & Development (CPD). The reviewer cannot verify if a qualified professional is performing the work. Always provide the contractor's full business name and active Colorado license number, and list exact model numbers for all HVAC units, furnaces, and exhaust hoods from the manufacturer's spec sheets.
2. Submitting Incorrect or Missing Floor Plans
Attaching old floor plans or omitting the mechanical plan sheet that shows ductwork, vent locations, and equipment placement is a top delay. Denver requires scaled plans that match the current layout submitted for your building permit. Submit a separate, clearly labeled mechanical plan that details all new and existing HVAC components; using an architectural plan without these specifics adds 2–3 weeks for resubmission.
3. Miscalculating Load Calculations or Ventilation Rates
Entering generic or incorrect heating/cooling load calculations (Manual J) or kitchen exhaust CFM rates leads to a plan review correction. Denver code (based on 2021 ICC Mechanical Code) requires specific calculations for the space. Have your HVAC contractor provide the signed, stamped manual J report and CFM calculations for hoods; guessing these values will fail review and require a professional's stamp.

Step 1: Gather required documentation including property address, contractor license numbers, supervisor certificate numbers, and scope of work details for your HVAC/mechanical system installation
Collect your restaurant's street address, the licensed mechanical contractor's Colorado license number, and the HVAC supervisor's certificate number before starting the form. You'll also need a detailed description of the work: whether it's a new unit installation, replacement of existing equipment, or ductwork modification. Most rejections at this stage come from using an incomplete or mismatched contractor license number — verify it matches the state contractor licensing database.
Step 2: Determine the class of work (New Building, Addition, Repair/Replace, or Alteration/Tenant Finish) applicable to your restaurant project
Select one of four categories on the permit form: **New Building** (rare for restaurants), **Addition** (expanding the building), **Repair/Replace** (swapping out a failed HVAC unit), or **Alteration/Tenant Finish** (reconfiguring ductwork or adding zones for a new dining area). This classification determines inspection requirements and fee tier. Most restaurant owners misclassify ductwork modifications as 'Repair/Replace' when they should mark 'Alteration' — contact Denver CPD if you're unsure.
Step 3: Complete the Mechanical Permit Input Form (MECH) with all required information including building use classification (Commercial for restaurant), site contact information, and detailed scope of work
Fill out the MECH form through Denver's Quick Permits portal (denver.gov/pocketgov). Mark building use as 'Commercial' and enter your restaurant's name, address, and phone. In the scope section, describe the work in 2–3 sentences: equipment model numbers, location in the building, and estimated completion date. The form has 23 fillable fields; ApronPrep auto-fills 18 (contractor info, building address, classifications) if you've entered this data elsewhere.

See All RequirementsProcessing time varies depending on the complexity of your HVAC system and whether your application is complete on first submission, per the Denver Community Planning & Development (CPD) website. Standard mechanical permits typically take 5–10 business days for plan review, though expedited review may be available for an additional fee. Contact Denver CPD at (720) 913-1311 to confirm current timelines for your specific project scope.
Denver does not charge a separate government filing fee for mechanical/HVAC permits under most circumstances. However, you may incur costs for required plan reviews, inspections, or contractor licensing if applicable — contact Denver Community Planning & Development to confirm any applicable fees for your installation scope. Not legal advice — verify current fee structure directly with Denver CPD.
No — mechanical/HVAC permits are location-specific and tied to the property address where the work is performed. If you are relocating your restaurant or moving equipment to a new location, you must apply for a new Building Permit and mechanical permit for the new site. Contact Denver CPD to confirm whether any prior approvals can be referenced in your new application.
Mechanical/HVAC permits do not require periodic renewal — they expire upon project completion and final inspection approval, per Denver CPD guidelines. Once your system passes inspection and receives sign-off, the permit is closed. You only need a new permit if you perform additional HVAC work or modifications to the system.
Denver CPD will inspect your HVAC installation to verify compliance with the International Mechanical Code (IMC) and local amendments, including ductwork sizing, ventilation adequacy, and proper refrigerant handling. The inspector will also confirm that any Backflow Prevention Device Certification requirements are met if your system includes water connections. Schedule your inspection through Denver CPD after rough-in work is complete; inspection typically takes 30–60 minutes on-site.
