Window Replacement · Mobile County, Alabama
Permit required
In Alabama, a Window Replacement requires a building permit.
The coastal areas of Mobile County are in Alabama's wind-borne debris region (within a mile of the coast at 130 mph or more, or anywhere at 140 mph or more; here around 130-140 mph), so replacing windows requires a permit and the new windows and doors must be impact-rated (ASTM E1886/E1996) or protected by approved shutters. Compliance is shown through the product's design-pressure rating or impact testing under the Alabama building code. Plans are reviewed under the Mobile County, AL (WBDR) code (IRC 2015 IBC (AL)); apply through Build Mobile before work begins.

Retrofit windows (inserting into existing frames) often do not require a permit, but new construction windows or altering the wall structure almost always requires an inspection.
With a population of around 412,590 residents, Mobile County generally runs a more streamlined permitting process than major urban hubs.
Code Compliance & Inspections
Because Alabama sits in a hurricane-prone zone, the Alabama Building Commission Code requires exterior work to use wind-rated materials and proper anchoring (such as tie-downs and impact-rated components) to pass inspection.
Concurrent Permits & HOAs
For Mobile County residents, we highly recommend reviewing your neighborhood HOA covenants before paying any municipal fees. Often, homeowners associations maintain stricter rules regarding materials and dimensions for your Window Replacement than the county itself.
Zoning & Cost Factors
Alabama relies heavily on local municipal zoning, with the state primarily adopting standard International Building Codes (IBC) without major statewide amendments. Fortunately, Alabama maintains relatively builder-friendly regulations, keeping base permit fees competitive.

Frequently Asked Questions
What are the specific penalties for unpermitted Window Replacement work in urban Mobile County?
Building without authorization is considered a code violation. The local government can issue a Stop Work Order, forcing you to halt construction immediately. You may be subject to retroactive permit fees (often double the original cost), daily fines, or even a mandate to tear down the unpermitted work at your own expense.
Can a homeowner pull their own Window Replacement permit in Alabama?
Yes. Alabama generally allows property owners to act as their own general contractor under an Owner-Builder exemption. If you take this route, you assume full legal and financial liability and must ensure all work complies with the Alabama Building Commission Code.
