Building permits in Unincorporated Mobile County

Most construction, renovation, and repair work in Unincorporated Mobile County, Mobile County needs a building permit from Mobile County Inspection Services. Below are the office's contact details and online portal, plus step-by-step guides for the projects homeowners ask about most, from roofing and solar to fences, sheds, pools, and HVAC.

Alabama has no state agency that issues building permits for homes, so a residential permit in Unincorporated Mobile County comes from the city or county only if that government has adopted a building code and runs its own permit and inspection program, and some unincorporated areas have no program at all. Under Act 2024-443 the Home Builders Licensure Board now adopts the Alabama Residential Building Code and the Alabama Residential Energy Code, which local programs enforce; the Board has proposed the 2024 IRC and 2024 IECC with Alabama amendments, and beginning January 1, 2027 licensed residential builders must build to that code or to the local code where one applies. There is no statewide dollar or size exemption from permits: the $10,000 threshold in the licensing law ($2,500 for roofing) decides who needs a state builder's license, not whether a permit is needed. Confirm with the city or county building office that has jurisdiction over the address in Unincorporated Mobile County, including a city's police jurisdiction outside its limits, before starting work.

Permit FAQs for Unincorporated Mobile County

Do I need a building permit in Unincorporated Mobile County?
Most construction, renovation, and repair work in Unincorporated Mobile County needs a permit, including structural changes, electrical, plumbing, mechanical, roofing, and pools. Small cosmetic work is sometimes exempt. Every project must still meet the residential code adopted by the city or county, or the Alabama Residential Building Code adopted by the Home Builders Licensure Board (IRC-based; the Board has proposed the 2024 IRC and 2024 IECC with Alabama amendments), even when a permit is not required.

Who issues building permits in Unincorporated Mobile County?
Mobile County Inspection Services issues permits for property inside Unincorporated Mobile County, Mobile County. Your mailing city is not always the authority that permits your property, so confirm the jurisdiction before you apply. This page lists the department's phone, address, website, and online portal.
Can I pull my own permit as a homeowner in Unincorporated Mobile County?
Under Ala. Code 34-14A-6(5), an owner in Unincorporated Mobile County who acts as their own contractor and provides all material supervision while building or improving a one-family or two-family residence for their own occupancy or use, not offered for sale, is exempt from Home Builders Licensure Board licensing, and a sale or offer for sale within one year of completion is presumptive evidence the work was done for sale. This is a licensing exemption only: state law also lets a property owner do their own electrical (Ala. Code 34-36-13), plumbing (Ala. Code 34-37-15), and heating and air work (Ala. Admin. Code r. 440-X-3-.05), but any permit and inspection the local office requires still applies.
Is there a dollar amount under which no permit is needed in Unincorporated Mobile County?
Not statewide. Alabama sets no statewide dollar threshold that waives a building permit, so whether small or cosmetic work needs a permit is decided locally. Confirm the exempt-work list and any value threshold with Mobile County Inspection Services before you start.
How much does a permit cost and how long does it take in Unincorporated Mobile County?
Fees and review times are set locally and change often, so confirm the current numbers with Mobile County Inspection Services or its online portal. Fees are usually based on the value of the work or a fixed schedule, and simple residential permits are frequently reviewed faster than new construction.
