Permits for Exterior Remodeling in Denver

Quick answer: Permits for exterior remodeling in he City and County of Denver says permits are required for most construction, alteration, or repair work on private property, and roofing and siding permits are issued through Denver Community Planning and Development. Contractors working in Denver must be licensed by the city, homeowners can pull a permit only for their own single-family home under specific conditions, and homes that are landmarks or in historic districts need a Certificate of Appropriateness before exterior work. Confirm the rules for your exact project with Denver CPD before you start.

The Short Answer

Denver’s Community Planning and Development department (CPD) states that “permits are required for most construction, alteration, or repair work on private property.” For exterior work that generally means roofing and siding projects need a permit, while the rules for other projects, like window replacement, decks, and fences, depend on the scope of the work, so check Denver’s current guidance before you start. Painting and similar finish work is generally treated as maintenance under model building codes. Always confirm the details for your address and project.

Who Can Pull the Permit?

Denver allows two paths. A licensed contractor can pull the permit and do the work, or the homeowner can pull the permit for their own home under strict conditions. According to Denver CPD’s homeowner permit page, a homeowner may pull a permit for a single-family home if they are the legal owner and resident, show a photo ID that matches the Assessor’s records, and live in the home for at least one year after the work is done. Permits can’t be issued to trusts, LLCs, or corporations, and homeowners can’t pull permits for accessory dwelling units, townhomes, condos, or duplexes.

Homeowners who pull a permit can either do the work themselves or act as their own general contractor. Denver says exams are not needed for residential construction or roofing and siding permits. If you act as your own general contractor, you must hire contractors licensed in the City and County of Denver for any work you don’t do yourself, and you are responsible for the permitted work.

Do I Need a Licensed Contractor in Denver?

Denver licenses contractors, and the city’s homeowner guidance says that if you act as your own general contractor you must hire contractors licensed in the City and County of Denver. Denver’s contractor license page describes a two-step process that starts with a supervisor certificate or a state electrical or plumbing license. When you hire a contractor, ask for their Denver license information and confirm it with the city, and ask who will pull the permit.

Historic Districts and Landmarks

If your home is a Denver landmark or is located in a historic district, exterior work, including alterations, may need Landmark Preservation design review. The review results in a Certificate of Appropriateness, which must be submitted with your building or zoning permit application. Reviewers apply the Secretary of the Interior’s Standards and the district’s design guidelines. Check before you order windows or siding for an older home.

HOA Rules Are Separate

A city permit does not replace HOA approval. Many Denver-area neighborhoods require approval for exterior colors, materials, and styles. Check your covenants early, because HOA review can take weeks.

What Codes Apply Now?

Denver CPD says the 2025 Denver Building and Fire Codes took effect on December 31, 2025, and that new construction drawings submitted after that date must use them. Your contractor should be working from the current codes.
