Mobile County, Alabama Building Permit Guide

Building permits for unincorporated Mobile County are issued by the Mobile County Inspection Services Department, part of Mobile County Public Works, at 1110 Schillinger Road N., Suite 100, Mobile (251-574-3507; Monday to Friday, 7:30am to 4:30pm). With about 411,700 residents (Census estimate, 2025) Mobile County is Alabama’s third-largest, and its permit system exists in its current form because of a hurricane.

This guide covers the department and how to reach it, the code edition that governs a filing here, what permits cost and who may pull them, and how inspections are booked. Rules that apply everywhere in Alabama are summarized in each section, with a link to the full statewide explanation.

This guide covers unincorporated Mobile County. The City of Mobile, Prichard, Saraland, Satsuma, Chickasaw, Semmes, Bayou La Batre and the county's other municipalities permit separately.

What requires a building permit in Mobile County?

Under the county's adopted codes, a permit is required before most construction, alteration, demolition, repair, relocation, change of occupancy and trade work begins in unincorporated Mobile County.

Exemptions are narrow and local, and an exemption from a building permit is not an exemption from zoning, setbacks, floodplain rules, utility approval or a fire authority review. Confirm scope with the department before work starts rather than after.

Which code edition applies

Mobile County adopts its construction codes by County Commission resolution for the unincorporated area. Since 1 July 2026 it has enforced the 2024 International Building, Residential, Mechanical, Plumbing, Fuel Gas, Swimming Pool and Spa, and Existing Building Codes and the 2023 National Electrical Code, with local amendments; the energy codes are those adopted by the Alabama Energy and Residential Codes Board. These editions are not necessarily the state’s or the City of Mobile’s, so confirm the position for your filing date with Inspection Services.

In Alabama, where a project is and what it is decide who reviews it, and whether anyone reviews it at all. There is a State Building Code, but its scope is deliberately narrow. There is a statewide residential code, but it is enforced only by local jurisdictions that run residential permitting and inspection programs (§ 34-14A-12(b)). And everything else — ordinary private commercial and residential work — is permitted and inspected locally, by whichever city or county has taken that job on.

The State Building Code is administered by the Division of Construction Management (DCM), a division of the Alabama Department of Finance (§ 41-4-400), under Title 41, Chapter 9, Article 6 of the Code of Alabama. DCM adopted the 2021 International Building Code effective 1 July 2022, and amended it on 17 March 2025 to pull in portions of the 2024 International Building Code and its companion codes. But DCM applies that code only to work on state-owned property or using state funds, to all public and private K–12 schools, to public postsecondary schools, and to hotels, motels and movie theatres. On municipal and county-owned projects DCM’s jurisdiction is limited to ADA Standards compliance. DCM has no jurisdiction over residential property, and none over commercial property beyond hotels, motels and theatres.

So for the overwhelming majority of private construction in Mobile County, the code that governs you is the one the Mobile County Inspection Services Department has adopted, and the office that enforces it is the local one.

From 1 January 2027, under Act 2024-443, a residential home builder must build to the applicable residential code (the Alabama Residential Building Code, or the local code where one applies) even where no building department inspects the work. Since 1 October 2024 the Alabama Home Builders Licensure Board adopts the residential code, and the Licensing Board for General Contractors the commercial energy code.

Who handles permitting in Mobile County?

Mobile County Inspection Services permits the unincorporated area. The City of Mobile and the county's other municipalities each permit their own limits, and in a city’s police jurisdiction outside its limits, who enforces building codes there depends on the city’s and county’s arrangements under § 11-40-10(b)(2).

The county's unincorporated territory runs from the suburban ring around Mobile out to the Mississippi line, down the western shore of Mobile Bay and along the Gulf coast at the southern end. Exposure varies substantially across that range: a parcel in the northern county faces a very different wind and flood picture from one near the bay or the coast, and criteria should be established for the specific site rather than for the county as a whole.

Alabama has a well-developed body of practice around fortified, wind-resistant residential construction on the Gulf coast, driven partly by insurance considerations and partly by hard experience. Higher construction standards can carry meaningful insurance implications for the eventual owner, which makes them worth raising with a client at design stage rather than presenting as pure cost.

In 2025, building permits issued in unincorporated Mobile County authorized 606 new privately owned housing units, all of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

A county’s building code applies in its unincorporated areas; inside a city it applies only with the city’s consent, so confirm for the specific parcel whether the city or the county issues. Outside the city limits, a county code may be enforced in a city’s police jurisdiction only as § 11-40-10(b)(2) provides. County authority and police jurisdictions in Alabama

Permit types

Residential permits

Residential work ranges from suburban subdivision construction to coastal and waterfront building where elevation, flood-resistant construction, wind design and access all shape the envelope. On repaired storm-damaged property, substantial improvement and substantial damage rules under the floodplain programme can trigger full compliance obligations on a project that began as a repair — establish that threshold before scoping the work.

Commercial permits

Commercial and industrial development reflects the port economy, shipbuilding, aerospace manufacturing, distribution and the retail and service base supporting a large metropolitan population. Coastal and waterfront commercial work brings wind, flood and environmental considerations alongside the building set, and larger projects add grading, drainage, access and fire review.

Statewide rules also shape Alabama submittals: commercial and multi-family plans must be sealed by an Alabama-licensed design professional where the thresholds require it; a parcel in a FEMA Special Flood Hazard Area generally needs floodplain approval before the building permit; where adopted, storm shelter (ICC 500) and coastal wind provisions drive the detailing; and no state, county or city body may require residential fire sprinklers (§ 34-14A-12.2).

Mobile County permit costs and fees

Mobile County permit fees for new structures are “all inclusive”: one fee covers building, electrical, energy, mechanical and plumbing work and is based on the total contract cost (materials and labour). A separate trade permit is issued only when a single trade does the work, such as an HVAC change-out or an electrical repair. Commercial plan review costs $100, paid at submittal; allow 5 to 10 working days for review. The City of Mobile maintains an entirely separate schedule.

Fee schedules are revised on each jurisdiction’s own cycle, so ask Mobile County for the schedule in force on your filing date, and ask separately about plan review, trade, re-inspection and revision charges. How Alabama permit fees work

Trade permits and who may pull them

Alabama licenses contractors through five state boards: the Licensing Board for General Contractors (undertakings of $100,000 or more), the Home Builders Licensure Board (residential work over $10,000, and residential roofing over $2,500), and separate electrical, plumbing and gas, and HVAC boards that license by trade regardless of project value. A local business licence and registration with the building department are commonly required as well. Contractor licensing in Alabama

How to apply for a Mobile County building permit

Review rules, permit duration, revival and appeal routes come from each Alabama jurisdiction’s own ordinance, so ask Mobile County which code editions apply on your filing date, how long a permit stays valid and where appeals go. Where a jurisdiction has adopted no building code, no building permit is issued, but zoning, floodplain, health and utility requirements can still apply. Review and corrections in Alabama

Inspections in Mobile County

Standard checkpoints include footing and foundation, framing, rough-in electrical, plumbing and mechanical, insulation, and final, with a certificate of occupancy before legal occupancy. Coastal work adds elevation verification and inspection of wind-resistive connections and opening protection, which must be observable when the inspector attends.

Wind-resistive detailing is the category most often missed at inspection on the coast, because much of it is concealed by the following trade. Sequence framing, sheathing, strapping and roof inspections so the connections can actually be seen, and keep elevation documentation on site.

Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, energy documentation, product listings, special-inspection reports and your correction responses available on site.

Mobile County permit search and official resources

Permit records sit with the authority that issued them, which in Alabama makes record research a jurisdictional question before it is a clerical one. A search of the wrong office returns nothing and proves nothing — and in parts of the state a property may genuinely have no permit history because no permit was ever required. If you are buying, refinancing or renovating an existing building, ask the Mobile County Inspection Services Department what it holds for the parcel, whether any permit was closed without a final inspection, and whether the property was inside the enforcing jurisdiction at the time the work was done.

Annexation, changing police jurisdiction boundaries and counties adopting codes at different times all mean that the authority over a parcel today is not necessarily the authority that governed it when a previous addition or alteration was built.

These are the primary sources behind this guide. Codes, fee schedules and portal procedures change, and in Alabama a jurisdiction’s own published packet can lag an adoption by months — the adopted ordinance governs, not an un-updated handout. Confirm the position for your filing date.

Frequently asked questions

Why does Mobile County permit its entire unincorporated area?

After Hurricane Frederic in 1979 and the poor repair work that followed, the County Commission extended the permit programme beyond the federally designated flood zone to cover the whole unincorporated county, adopting codes by resolution on 12 January 1981 under section 41-9-166.

Which code edition does Mobile County enforce?

The 2024 International Codes and the 2023 National Electrical Code, adopted by County Commission resolution and in effect since 1 July 2026. The adoption history runs from the 1981 resolution through the 2000 editions, the 2006 editions in 2008 after Hurricane Katrina, and the 2012 editions in 2014. Confirm the position for your filing date with Inspection Services.

What does a FEMA flood zone mean for my project?

It brings elevation and flood-resistant construction requirements and generally a floodplain development approval before the building permit. On repairs, substantial damage and substantial improvement thresholds can trigger full compliance.

Does the City of Mobile use the same requirements?

No. The city permits its own limits under its own adopted codes and fee schedule. The county covers unincorporated territory, and in a city’s police jurisdiction outside its limits, who enforces building codes there depends on the city’s and county’s arrangements under § 11-40-10(b)(2).

What changes on 1 January 2027?

Under Act 2024-443 a residential home builder must build in accordance with the applicable residential building code from that date. The duty attaches to the builder's licence rather than to a local building department, so it applies even where no inspector will attend.

Does better wind construction affect insurance?

Stronger wind-resistive construction can carry meaningful insurance implications for the eventual owner on the Gulf coast. It is worth discussing with the client at design stage rather than treating it purely as added cost.

Simplify Mobile County permitting with Alliance Permitting

Mobile County is a coastal permitting environment where the binding constraints — design wind, flood elevation and floodplain compliance — are established before design and are effectively impossible to retrofit afterwards. The programme itself exists because of a storm, and it still reflects that.

Trusted by leading builders, developers, and national contractors — 21+ years of filing in the jurisdictions we write about.

Contractors and builders choose Alliance for Mobile County because the work is done by people who have stood at the counter:

• We establish flood zone and design wind criteria for the parcel before design begins.
• We confirm the county's current adopted edition rather than assuming a cycle.
• We test repair scopes against substantial damage and improvement thresholds early.
• We sequence inspections so concealed wind-resistive connections can be observed.
• We keep county, city and police jurisdiction boundaries straight before filing.

Alliance Permitting is a permit documentation and submission company in Alabama. We prepare your paperwork, file it correctly and coordinate with the building department through issuance. We are not a contractor and we do not perform licensed plan review or inspections; that work stays with your licensed team and the jurisdiction.
