Missouri building departments
This Missouri directory covers 115 Census county equivalents and local building-department guides. Missouri permitting is strongly jurisdiction-specific. The city, county, or village may have different adopted codes, forms, fees, and inspection procedures.
How permitting works in Missouri
Primarily local code adoption. 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.

Missouri Department of Natural Resources / local jurisdictions
Missouri’s building codes are adopted by individual jurisdictions. The state publishes a jurisdiction-by-jurisdiction reference, but it cautions that local amendments and trade codes must be confirmed with the city or county authority.
