Quick Answer: In Denver, permits are generally required for any renovation involving structural changes, new or relocated electrical circuits, plumbing changes, or work that alters a home’s footprint. Purely cosmetic updates — paint, flooring replacement on the same subfloor, cabinet refacing — typically do not require a permit. When in doubt, it’s always worth confirming with your contractor or the city before starting, since unpermitted work can create real problems later.
Permits are one of the least exciting parts of a remodel, and it’s tempting to see them as red tape that slows a project down. In practice, they exist to make sure structural, electrical, and plumbing work is inspected and safe — and skipping them can cause far bigger headaches than the permit process itself.
What Renovation Work Typically Requires a Permit in Denver?
- Any structural changes, including removing or altering a load-bearing wall
- New electrical circuits or panel upgrades
- New or relocated plumbing, including moving a sink, toilet, or shower drain
- Additions or changes to a home’s exterior footprint
- Converting a basement or attic into finished living space, especially if it includes a bedroom or bathroom
- Window replacement that changes the size of the rough opening
- Deck construction or major exterior structural work
What Typically Does NOT Require a Permit
- Painting (interior or exterior)
- Replacing flooring on an existing subfloor without structural changes
- Cabinet refacing or painting (without moving plumbing or electrical)
- Replacing a like-for-like fixture (e.g., swapping a faucet without relocating pipes)
- Minor cosmetic updates that don’t touch structural, electrical, or plumbing systems
Important: requirements vary by municipality. Denver, Aurora, Lakewood, Arvada, and other metro cities each administer their own permitting process, so a project that’s permit-exempt in one city may require a permit in another.
How the Permit Process Works
- Plans are submitted to the city or county, detailing the scope of work — often including drawings for structural, electrical, or plumbing changes.
- Plan review occurs, where the jurisdiction checks the proposed work against current building code.
- The permit is issued, and construction can begin once it’s in hand.
- Inspections occur at key phases of construction — for example, after rough electrical and plumbing are installed but before drywall closes the walls, so inspectors can verify the work before it’s hidden.
- A final inspection confirms the completed work matches code, and the permit is closed out.
Permit review timelines vary based on project scope and current volume at the local building department, with more complex projects (additions, structural changes) generally taking longer to review than straightforward kitchen or bathroom remodels.
What Happens If You Skip a Required Permit?
Unpermitted work that should have been permitted can create serious problems down the road:
- Home sales can be complicated. Buyers, their lenders, and inspectors often identify unpermitted work, which can delay or derail a sale, or require the seller to obtain retroactive permits and inspections before closing.
- Insurance claims can be denied. If damage occurs (a fire, a plumbing failure) related to unpermitted work, insurance companies may deny the claim.
- You may be required to open up finished walls. If unpermitted work is discovered, the city can require it to be exposed for inspection — meaning finished drywall, tile, or flooring may need to be removed and redone.
- Fines and retroactive permit fees are common when unpermitted work is discovered.
The upfront cost and time of a permit is almost always smaller than the cost of correcting unpermitted work later.
Who Is Responsible for Pulling Permits?
In most cases, a licensed general contractor pulls permits on your behalf as part of the project scope, since permits are typically issued to a licensed contractor rather than a homeowner (with some exceptions for owner-performed work on their own primary residence). This is one more reason working with a licensed, established contractor matters — an unlicensed contractor may not be able to pull permits at all, leaving the work unpermitted by default.
How to Confirm What Your Project Needs
If you’re unsure whether your specific project requires a permit, the most reliable path is:
- Ask your contractor directly, and confirm they will handle the permit application as part of the project.
- Check your city’s building department website or call directly if you want to verify independently.
- Never assume a project is “too small” to need a permit — many homeowners are surprised to learn that things like moving a bathroom sink a few feet do require one.
Frequently Asked Questions
Q: Do I need a permit to remodel my kitchen in Denver? A: If your kitchen remodel involves relocating plumbing, adding electrical circuits, or removing a wall, you’ll need a permit. Purely cosmetic work like painting cabinets or replacing a countertop without moving plumbing generally does not require one.
Q: Do I need a permit to finish my basement? A: Yes, in nearly all cases. Basement finishing typically involves framing, electrical, and often plumbing work, all of which require permits, along with meeting egress requirements if a bedroom is included.
Q: What happens if I sell my house with unpermitted work? A: It can complicate or delay the sale. Buyers’ inspectors and lenders often flag unpermitted work, and you may be required to obtain retroactive permits, undergo inspections, or make repairs before the sale can close.
Q: How long does it take to get a permit approved in Denver? A: Timelines vary by project complexity and current volume at the building department, ranging from a few days for straightforward projects to several weeks for more complex structural work. Your contractor can give you a realistic estimate based on current conditions.
Q: Can I pull my own permit instead of having my contractor do it? A: In many jurisdictions, homeowners can pull permits for work on their own primary residence, but a licensed contractor typically handles this as part of a full-service remodel, since they’re familiar with the specific requirements and inspection process.
