What requires a building permit in Fort Collins?
Under the 2021 IBC/IRC with Fort Collins amendments, a permit is required for most construction activities:
Permit required
- New residential and commercial construction, additions
- Structural and load-bearing alterations
- Reroofing, windows, siding, and exterior changes
- Electrical service changes and most wiring work
- HVAC installations and changeouts
- Plumbing alterations, repipes, and water heaters
- Decks, pools, fences, patio covers, carports
- Change of occupancy or use
Typically exempt
- Painting, wallpapering, tiling, carpeting, cabinet installation
- Countertop replacement and similar finish work
- Retaining walls ≤ 4 ft (not supporting surcharge)
- One-story detached sheds ≤ 200 sq ft (on grade, no utilities)
Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get the permit issued before starting work. Building without one exposes the owner to penalties, fines, and stop-work orders. In Denver, fines range from $150–$999 per violation. Unpermitted work can also create issues when selling the property.

Fort Collins trade permits
Electrical, plumbing, and mechanical work each needs its own permit and appropriately licensed tradespeople.
Electrical permits
Required for service installations, panel upgrades, solar PV, EV chargers, and most wiring alterations — performed by a contractor licensed through the Colorado State Electrical Board.
Plumbing permits
Required for new plumbing, repipes, water heater changeouts, fixtures, backflow, and sewer connections — performed by a contractor licensed through the Colorado Examining Board of Plumbers.
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, ductwork changes, and venting modifications — performed by a qualified mechanical contractor per local requirements.
Miscellaneous & specialty
Fencing, pools, decks, sheds, and patio covers may require special permits depending on size and utility hookups. Demolition, sign, and right-of-way permits follow separate tracks.
Verify contractor licensing. Colorado does not issue a statewide general contractor license — general contractor licensing is handled at the local city or county level. However, trade licenses are state-regulated: electricians are licensed by the Colorado State Electrical Board and plumbers by the Colorado Examining Board of Plumbers. Always verify your contractor meets both state trade requirements and local licensing. The Colorado Wildfire Resiliency Code (2025) sets fire-resistant construction standards in wildland-urban interface zones. Verify licensing at dpo.colorado.gov/EandP.
