How to get a building permit in Alabama

1

Find your local building department

Alabama permits are issued at the city or county level. Jefferson County, Mobile, and Huntsville have full-service departments. Contact your municipality first.

2

Determine if plans are required

Trade permits rarely need plans. Structural work — additions, new construction — requires architectural plans in most jurisdictions.

3

Submit application and pay fees

Fees are based on project valuation. Alabama fees are generally below the national average.

4

Inspections

Cities require phase inspections. Rural areas may have limited inspection staff — schedule in advance.

5

Certificate of Occupancy

Required for new construction and major additions before the space can be used.
