How building permits work in Alabama
These rules apply across Alabama. Each local guide above covers what is specific to that jurisdiction: its building department and contacts, the codes it has adopted, local conditions, fees and inspections.
The State Building Code and the 2027 residential code
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.
The most important date in Alabama construction right now is 1 January 2027. Under Act 2024-443, § 34-14A-12.1 of the Code of Alabama provides that beginning 1 January 2027, a residential home builder who constructs, renovates or repairs a residence or structure in this state shall do so in accordance with the applicable residential building code — either the Alabama Residential Building Code adopted under § 34-14A-12, or the local jurisdiction’s residential building code where one applies.
The duty is placed on the residential home builder, not on a building department. It does not require any city or county to start inspecting. It means that from 1 January 2027 an Alabama home builder must build to the applicable residential code even in a jurisdiction where no building department exists to check the work.
Act 2024-443 also moved who writes the codes, effective 1 October 2024. Residential building code adoption authority passed from the Alabama Department of Economic and Community Affairs to the Alabama Home Builders Licensure Board, with a new Alabama Residential Building Code Advisory Council and an Alabama Residential Building Code Division. Commercial energy code authority passed to the Alabama Licensing Board for General Contractors, through an Alabama Commercial Energy Code Advisory Committee. Both code-writing bodies are now licensing boards — in Alabama, the board that licenses your builder also writes the code your builder must follow.
The Alabama Residential Building Code is defined at § 34-14A-2 as a code based on a published edition of the International Residential Code together with the residential chapters of a published edition of the International Energy Conservation Code. Confirm the edition the Board has actually adopted, and the transition arrangements, before you design against it — this is a live process with a fixed deadline, not a settled position.
County authority and municipal police jurisdictions
County authority is statutory. Under § 34-14A-12(c), as amended by Act 2024-443 from 1 October 2024, a county commission may adopt building laws and codes by resolution for the unincorporated areas of the county. They take effect 120 days after the resolution, and a commission may discontinue enforcement the same way. A county’s code applies inside a city’s corporate limits only with the city’s express consent.
Two further provisions matter. § 34-14A-12(d) lets a county commission condemn dangerous buildings using the municipal procedures at §§ 11-53A-20 to 11-53A-26. And § 34-14A-12(e) authorises county commissions, municipalities and other public entities to enter mutual agreements, compacts and contracts for administering and enforcing their respective building codes — so in some parts of Alabama a county issues permits inside cities that have agreed to it.
In Alabama, “is there a code?” and “will anyone enforce it?” are two different questions. County building codes are optional, and some counties have adopted none for their unincorporated areas: Limestone County, for example, states that no building inspections are required there. Where no local government enforces a building code, no building permit is issued, though zoning, floodplain, health department and utility requirements can still apply.
Sealed plans, flood, storm and sprinkler rules
Commercial and multi-family plans must be sealed by an Alabama-licensed design professional where the project falls within the thresholds and occupancy categories that trigger it. Those triggers are set by state licensing law and by local requirements, and jurisdictions apply them at different points, so confirm the sealing requirement for your specific building area, occupancy and scope before drawings are finalised rather than discovering it at intake.
Flood, wind and storm-resilient construction
Alabama sits at the intersection of two serious natural hazard exposures, and both show up in the permit file rather than only in the design. On flood, a parcel inside a FEMA Special Flood Hazard Area generally requires a floodplain development approval before a building permit can be issued — several Alabama jurisdictions administer this as a separate Flood Development Permit with its own application, and it is a prerequisite rather than a parallel step. Establish the flood zone from the effective map for the parcel at the start of the project.
On wind and storm, coastal wind design provisions drive connection, cladding and opening protection detailing, and some jurisdictions have adopted the ICC 500 storm shelter standard (Cullman, for example). Confirm both with the department before design.
Alabama prohibits mandatory residential fire sprinklers
§ 34-14A-12.2 provides that, from 1 October 2024, the Home Builders Licensure Board and any other state, municipal or county governing body may not adopt or amend a building code, ordinance, resolution or rule that would restrict a consumer’s ability to elect to install — by the consumer’s own choice and for a fee — or that would require the installation of a residential fire sprinkler system. A county commission or municipal governing body may continue to enforce measures it adopted on or before 9 March 2010.
Alabama protects the consumer’s own election either way. The practical consequence for a builder is simple: sprinklers may be offered, specified and installed by choice, but no state, county or city body can require them.
How permit fees work
Fee schedules in Alabama are set by the adopting jurisdiction and revised on its own cycle, so a figure quoted from a neighbouring city, an older packet or a national estimator is not a reliable number here. Ask the department for the schedule in force on your filing date, and ask separately about plan review, trade, and any re-inspection or revision charges, which are frequently billed as distinct lines.
Contractor licensing: five state boards
Trade permits are often separate from the building permit and issued to the licensed installer, though some counties include all trades in one permit. Alabama licenses contractors at state level, but across five separate boards rather than one, and the board depends on the trade and the value of the work. A local business licence and registration with the building department are commonly required on top of the state licence before a permit will issue.
Alabama splits contractor oversight across five separate state boards. Getting the right one is not optional: the permit will not issue to a contractor who is not licensed by the board that covers the work.
- Alabama Licensing Board for General Contractors (LBGC) — undertakings of $100,000 or more (§ 34-8-1, since Act 2024-277), and swimming pools where the cost exceeds $5,000; from 1 October 2026 residential swimming pools are exempt (Act 2026-396). Since 1 October 2024 the LBGC also holds adoption authority for the commercial energy code.
- Alabama Home Builders Licensure Board (HBLB) — residential builders for work over $10,000 on homes and buildings of up to four units, and residential roofers for work over $2,500 (§ 34-14A-2). The HBLB now also adopts the residential building code. Unlicensed residential home building is a Class A misdemeanour.
- Alabama Board of Electrical Contractors — electrical work.
- Alabama Plumbers and Gas Fitters Examining Board — plumbing and gas fitting.
- Alabama Board of Heating, Air Conditioning and Refrigeration Contractors (HACR) — mechanical work.
The three trade boards license by trade regardless of project value, so there is no dollar threshold to fall under on electrical, plumbing, gas or mechanical scope. Local business licensing and registration with the building department are commonly required on top of the state licence.
How licensing interacts with permitting
The dollar thresholds above are licensing thresholds, not permit thresholds. A project below a licensing figure still needs a permit wherever the local jurisdiction requires one, and a project above it still needs the right licence even in a jurisdiction that issues no permits at all. The two systems run independently, and after 1 January 2027 the licensing system carries a code obligation of its own.
Review, corrections and places with no building department
Because enforcement in Alabama is local, the procedural rules around review, correction, appeal and permit expiry come from the adopting jurisdiction’s own ordinance and the administrative chapter of the code it has adopted — not from a statewide administrative code. That is a real practical difference from states with a single unified code: two Alabama jurisdictions can enforce identical technical provisions and still differ on how long a permit lasts, what revives an expired one, how a correction cycle is counted and where an appeal goes.
Ask the department three questions before you file: which code editions and local amendments govern a permit issued on your filing date, how long the permit remains valid and what constitutes the activity needed to keep it alive, and what the appeal route is if plans are rejected. Those three answers are jurisdiction-specific in Alabama and they are cheap to obtain in advance.
What if the jurisdiction has no building department?
In parts of Alabama this is a real question rather than a hypothetical, and the answer has two parts. First, a county or municipality that has not adopted building codes issues no building permit, so there is nothing to apply for — but zoning, subdivision, floodplain, health department and utility requirements can still apply, and they are administered separately.
Second: an absence of local enforcement is not an absence of obligation. From 1 January 2027 the residential code duty under Act 2024-443 attaches to the residential home builder wherever the work is done. A builder who treats an unenforced area as an unregulated one is taking a licensing risk, and an owner in that position has no permit record and no inspection history to rely on at resale, refinancing or insurance. Where no local inspection exists, third-party inspection and documented compliance are worth commissioning voluntarily.
