Jurisdiction Alert: City vs. County Permits
Before using this directory to locate county building department contacts, verify if your property lies within incorporated city limits. Incorporated municipalities (cities and towns) typically operate their own independent building departments and issue their own permits, whereas unincorporated areas are served by the county building department. Applying to the wrong department will result in delays and fee forfeiture.
🛠️ State Building Codes & Authority
Every county and municipality in Colorado adopts building codes derived from national standards (such as the International Building Code - IBC). However, local jurisdictions frequently enact specific local amendments concerning climate, snow loads, or seismic activity. Always refer to the state's central building authority for uniform licensing, electrical inspection codes, and accessibility compliance guidelines.

Do I need a permit if I am doing the work myself?
Yes. In most counties across Colorado, owner-builders can obtain permits for their primary residence, but all work must still pass building code inspections. Certain specialty trades (like major electrical panels or sewer connections) may require a licensed master contractor.
What happens if I build without a permit in Colorado?
Local building departments have the authority to issue a Stop Work Order, levy double permit fees as penalties, or demand that unpermitted work (such as drywall or concrete) be demolished to expose structural members for inspections. Unpermitted work must be disclosed at property resale and can void insurance claims.
