Denver Permit Requirements for Garage Door Replacement

The most common question Denver homeowners ask before a garage door project is whether they need a permit. The answer depends on the scope of work, and Denver CPD's guidance is less definitive than homeowners would like.

What this source says

Denver's Community Planning and Development (CPD) publishes a homeowner permit guide for single-family and duplex projects. For garage work:

Denver requires a building permit "for a single-family home (may include a garage)" for work that alters the structure, changes occupancy, or involves mechanical or electrical systems.

Homeowners (not just licensed contractors) can pull their own permits for garage projects. The process includes plan review, permit issuance, and inspections. E-permits are available for some simple projects.

The guide does not list a blanket garage door exemption. It does explicitly exempt "replacing like-for-like plumbing fixtures, such as faucets and sinks." No matching exemption exists for garage doors.

Denver's 2025 Building Code follows the 2024 IRC. IRC Section R105.2 lists minor repairs that skip the permit process. Full garage door panel replacement is not on that list.

When it applies

Based on the published code and CPD guidance, here is the practical breakdown:

Permit required: - Changing the door size or the rough opening - Adding a new door opening to an existing garage wall - Changing the structural header above the opening - Installing a new electric operator where none existed (may also need a separate electrical permit) - Altering the fire separation wall between the garage and the house

Likely exempt (confirm with CPD first): - Same-size door in the same opening, same hardware points, no framing changes - Replacing individual damaged panels with no changes to the door configuration

Safest path: call Denver CPD (phone number listed at denvergov.org) or use the online permit wizard at denvergov.org before starting. Unpermitted work can cause problems when you sell or file an insurance claim.

For example: a homeowner in Capitol Hill wants to replace their 1960s single-car wood door (8x7) with a new insulated steel door of the same size. No structural changes, same rough opening, same header. This is likely a permit-exempt like-for-like replacement. But the same homeowner who wants to widen the opening from 8 to 9 feet must pull a permit. That work involves cutting the wall framing and sizing a new header.

What this means for you

For a same-size door swap: ask your contractor whether they will pull a permit. A good contractor knows current CPD rules and will tell you straight. If they say "we never pull permits," ask them to confirm in writing that CPD does not require one for your specific job.

For any structural change: plan on a permit and budget for it. Minor residential project fees in Denver are usually $50 to $200. The inspection is quick for a standard door swap.

Apply online at denvergov.org/permits. Simple projects may qualify for an e-permit with no site visit needed.

Bring your wind label. If an inspector comes out, they may check the door's wind pressure rating label (required by IRC R609.4.1). Make sure it is visible.
