Local Project Overview
Deck Construction · Mobile County, Alabama
Set by local rules
In Mobile County, whether a Deck Construction needs a permit is set locally, and the county does not publish a single fixed threshold.
Mobile County Inspection Services enforces the adopted building code for unincorporated areas, but the county has confirmed there is no zoning in its unincorporated areas at all. No specific deck size or height exemption number is published separately from the general Alabama IRC-based standard used elsewhere in the state. The reliable answer comes from Build Mobile. Zoning setbacks apply either way.

Building a deck typically requires a permit if it is attached to the house, over 30 inches off the ground, or exceeds a certain square footage (often 200 sq ft).
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.
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 Deck Construction 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.

Can a homeowner pull their own Deck Construction 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.
How much does a Deck Construction permit cost in Mobile County?
