Who issues building permits in Alabama?
Local dept., local code
Permits in Alabama are issued by the city building department when the property is inside city limits, and by the county otherwise. Because local adoption of the irc; statewide code applies to state-funded and manufactured housing, requirements can differ between neighboring jurisdictions — verify before you plan the work.
Owner-builder: Homeowners may generally permit work on a home they own and occupy, subject to local rules.

Alabama permit questions
Do you need a permit for home renovations in Alabama?
Alabama does not enforce a single statewide residential code — local adoption of the irc; statewide code applies to state-funded and manufactured housing. Whether a permit is required can genuinely differ between neighboring jurisdictions. Structural, electrical, plumbing, mechanical and envelope work almost always require one.
Can a homeowner pull their own permit in Alabama?
Homeowners may generally permit work on a home they own and occupy, subject to local rules. Owner-builder status usually makes you responsible for code compliance and for any unlicensed work performed on the property, and many jurisdictions restrict resale within a year of the permit.
Are home projects more expensive in Alabama?
Our model puts Alabama at 10% below the national baseline for installed residential work, with permit fees at -15% versus baseline. Coastal Baldwin and Mobile counties enforce wind-borne debris requirements that inland Alabama does not, which changes roofing and window pricing sharply within one state.
