How Alabama licenses contractors

The Licensing Board for General Contractors licenses Building (BC), Heavy/Railroad (H/RR), Highway, and Specialty contractors. HVAC, refrigeration, and gas fitters are licensed through the Board of Heating, Air Conditioning & Refrigeration Contractors. Applicants pass PSI trade exams (NASCLA accepted for Building), pass the Business & Law exam, submit financials, and carry insurance.

Expect hurricane surge, 140-degree rooftop heat, limestone sinkholes, and tornado debris fields. Exams highlight wind uplift, floodproofing, OSHA heat plans, and red-clay erosion control.

What trips Alabama applicants up

Alabama splits contractor licensing across two boards: the LBGC for commercial/public projects ($100,000+) and the Home Builders Licensure Board for residential work over $10,000 — many applicants apply to the wrong one. Your bid-limit class is driven by your CPA financial statement (net worth and working capital), not by the exam, so weak financials cap your license size even after you pass.

Who needs an Alabama contractor license (and who does not)

Alabama splits commercial/public work (LBGC) from residential home building (HBLB). Applying to the wrong board wastes months.

Mechanical / HVAC / plumbingCovers: Statewide regulated mechanical trades
Authority: Heating & Air Conditioning Board (and related trade boards) — not a substitute for LBGC/HBLB

NASCLA acceptance in Alabama

Alabama accepts the NASCLA Accredited Exam for Building and Commercial contractor classifications and for the Home Builder exam path.

Confirm the current board bulletin before you schedule, then drill timed practice so Business & Law and remaining state filing steps do not surprise you after a NASCLA pass.
