Alabama's general-contractor law generally applies at $100,000 or more, including labor and materials.
Build the right Alabama license lane.
A contractor-focused guide to Alabama general contractor licensing, residential home builders, electrical, HVAC, plumbing, roofing, specialty trades, permit signals, project timing and official verification.

Residential construction, repair or improvement above $10,000 generally enters Home Builders Licensure Board jurisdiction.
Residential roofing has a lower licensing threshold under Alabama home-builder law.
General-contractor licenses carry a maximum single-contract bid limit based on financial capacity.
Two major construction lanes.
Alabama separates large commercial/public general contracting from residential homebuilding, while electrical, HVAC/refrigeration and plumbing/gas fitting are regulated through their own trade boards.
Start with project type, contract value and trade scope.
For commercial and public work, the Alabama Licensing Board for General Contractors generally regulates undertakings of $100,000 or more, including labor and materials. Swimming pool work is treated separately at $5,000 or more. Residential construction, remodeling, repair and reimprovement generally fall under the Home Builders Licensure Board when the undertaking exceeds $10,000, with residential roofing regulated above $2,500.
Separately licensed trades—including electrical, heating/air conditioning/refrigeration, plumbing and gas fitting—must follow their own board requirements even when the work is part of a larger project.
Choose the correct prime-contractor lane.
Alabama does not use one universal contractor license. Large commercial/public work and residential homebuilding are administered under different statutes and boards.
Building Construction
Building Construction covers building structures, modifications and additions intended for shelter, protection, comfort or convenience, including excavation, foundations and incidental work. The General Contractors Board may issue a major BC classification or narrower BC specialty classifications based on documented experience.
Unlimited Residential Home Builder
Residential work above the statutory threshold may require a Home Builders license. Alabama's rules distinguish unlimited work from limited single-trade/nonstructural work and from the residential-roofer license. Structural work or work involving multiple trades can require the broader residential license.
Limited Home Builder
Alabama rules provide a limited-license path for qualifying residential repair, improvement or reimprovement that does not affect structural integrity and does not involve more than one trade. Scope should be checked against the current Home Builders law and rules before contracting.
Residential Roofer License
Residential roofing is specifically included in Alabama's home-builder law at an undertaking exceeding $2,500. This is materially lower than the general $10,000 residential threshold and is one of the most important trade-specific distinctions for Alabama roofers.

Residential specialty work can fall into Alabama's limited-home-builder or roofer pathways, while commercial work may use General Contractors Board sub-classifications when the statutory threshold is met.
Painting contractors
Residential single-trade painting can fit the limited-license concept when the statutory residential threshold and scope conditions are met. Large commercial painting/wallcovering work appears as a BC specialty classification.
Concrete contractors
Commercial concrete is a recognized BC specialty classification; residential concrete work should be checked against structural impact, number of trades and the Home Builders threshold.
Framers
Framing is a recognized BC specialty classification on qualifying commercial projects. Residential structural framing typically points toward the broader home-builder license because structural integrity is affected.
Flooring & carpet contractors
Flooring is recognized within the BC specialty list. Residential floor-covering work can fall into a limited single-trade lane when statutory conditions are satisfied.
Tile & masonry contractors
Masonry is a BC specialty classification. Tile/stone scope should be qualified by project type, substrate, structural impact and whether the work is part of a broader residential improvement.
Drywall & metal-stud contractors
Drywall & Metal Studs is a listed BC specialty. Residential drywall work can be a strong permit-stage signal during remodels and new-home construction.
Roofing contractors
Commercial roofing and sheet metal are recognized under BC specialties; residential roofing has its own HBLB threshold above $2,500.
Sitework contractors
Commercial sitework is recognized as a BC specialty and also appears across municipal/utility and heavy classifications depending on project scope.
Pool contractors
Swimming-pool construction, repair or renovation enters the General Contractors Board definition at $5,000 or more.
Suppliers & distributors
Suppliers do not substitute for licensed contractors, but permit type and construction stage can reveal likely demand for concrete, framing packages, roofing, electrical gear, HVAC equipment, plumbing materials and finishes.
Build the license around the work you intend to perform.
Alabama's general-contractor process is classification-driven and tied to documented work experience and financial capacity. Residential and skilled trades use separate application systems.
Choose the board
Determine whether the project belongs under the General Contractors Board, Home Builders Licensure Board, Electrical Contractors Board, HACR Board or Plumbers & Gas Fitters Board.
Choose classification
For general contracting, request the major or specialty classifications supported by documented experience. Prime applicants generally provide project references and complete the Board's application process.
Meet exams + finance
Prime GC applicants take a Business and Law exam; other examinations can apply by classification. Bid limits are tied to financial statements and generally cannot exceed ten times the lesser of working capital or net worth.
Verify before bidding
Confirm the active license, classification, bid limit, business name and any separately required trade-board credential before submitting a bid or contract.
A: up to $100,000 · B: up to $250,000 · C: up to $500,000 · D: up to $1,000,000 · E: up to $3,000,000 · U: Unlimited. Always verify the current Board rule and the individual license record.
The Alabama General Contractors Board currently lists reciprocity with Arkansas, Louisiana, Mississippi, North Carolina and Alabama, generally requiring at least one year of licensure in the same classification requested. Electrical and plumbing reciprocity follow their own board rules.
The state credential is only one layer.
Local permits, building-code enforcement, business registration, workers' compensation and trade-specific rules still matter after the state license is issued.
State + local permits
Alabama municipalities and counties can administer permitting and inspections. Verify the authority having jurisdiction for the project address and do not assume one city uses another city's process.
State building code
The Alabama Division of Construction Management identifies the 2021 International Building Code as the State Building Code, with amendments adopted March 17, 2025 incorporating specified 2024 IBC provisions. Other listed state codes include the 2021 IEBC, IPC and IFGC.
Review State Building Code ↗Workers' compensation
Alabama generally exempts employers that regularly employ fewer than five workers, but the construction of new single-family detached residential dwellings is specifically treated differently. Verify coverage obligations with the Department of Labor.
Review workers' compensation ↗License verification
Always verify the precise entity, classification, status and bid limit. A trade label on a permit or website should not substitute for the official board record.
Read what the Alabama project is telling you.
A permit is a public project signal—not a guarantee that work is still available. The value comes from matching the record to trade, scope, timing, geography and incumbent-contractor context.
Early filing through plan review can reveal future subcontracting and material demand.
