Permit likely required

Most likely yes. Deck construction or replacement usually requires a permit in Colorado. Confirm the specifics with Unincorporated Delta County.

Colorado has no statewide building code. Building codes are adopted and enforced by each city or county, and some jurisdictions have adopted none; where that happens the state adopts codes only for hotels, motels, and multifamily buildings, not single-family homes. Whether a small, low deck is exempt depends on the code your city or county adopted. In wildland-urban interface areas with a moderate or high fire hazard severity, the Colorado Wildfire Resiliency Code (Section 404.5) requires the walking surface of an unenclosed deck to be noncombustible, Class A rated, or another listed ignition-resistant option. Local governments with WUI areas had until July 1, 2026 to adopt a code that meets or exceeds it.
