Colorado building departments
This Colorado directory covers 64 Census county equivalents and local building-department guides. Colorado is highly local for permitting. Home-rule municipalities and counties may adopt their own codes, so the property jurisdiction is the first research step.
How permitting works in Colorado
Home-rule and local administration. A county name is a geographic index, not a promise that the county government issues every building permit. Many projects are handled by a city, town, township, borough, parish, regional office, or independent city.

Colorado State Buildings Program / local jurisdictions
Colorado has no single statewide building code for ordinary local construction; building codes are primarily adopted and enforced locally. State-owned or state-leased projects have separate state requirements.
