How to pass the Alabama general contractor exam

A $100,000 license threshold, bid limits tied to your financial statement, and two open-book exams. Here’s how the Alabama prime contractor license works and how to study for it, checked against the board’s, the Code of Alabama’s and PSI’s own documents.

At a glance

LicenseGeneral contractor (prime) license, issued by the Alabama Licensing Board for General Contractors. It lists the types of work you may bid and a letter showing your bid limit on any one contract.
When you need itWhen the cost of the undertaking is $100,000 or more (raised from $50,000 on October 1, 2024). Swimming pool work over $5,000 also counts. Homes and other private dwellings are exempt from this board.
The examsEvery prime takes the Business and Law exam (50 questions, 70% to pass). For Building Construction (Commercial), the trade exam is the national NASCLA exam (115 questions, 81 correct to pass). Both are open book.
Who runs themThe board approves your application. PSI schedules and gives the exams on computer at its centers in Birmingham (Vestavia Hills), Huntsville, Mobile and Montgomery, and other PSI sites nationwide.
Bid limitsSet at no more than 10 times your net worth or working capital, whichever is less, from a CPA-prepared financial statement. Limits run from A (up to $100,000) to U (unlimited).
SubcontractorsSubs working under a general contractor on undertakings of $100,000 or more also need a license, but they pay half the fees, have no bid limit and don’t sit for an exam.

Question counts, times and passing scores are from PSI’s Alabama General Contractors candidate bulletin (updated 1/23/26). The board decides which exams you take. The Alabama bulletin says up to ten unscored experimental questions may be added and count against exam time. PSI’s own NASCLA bulletin says the NASCLA exam’s 10 pretest questions have time added for them. PSI charges $96 per exam, or $106 for Building Construction (Commercial).

Before you apply

  • Citizenship: a U.S. citizen, or legally present in the U.S. with federal documentation.
  • Application and fee: a $300 application fee (non-refundable), filed at least 30 days before a regular board meeting. The board meets quarterly.
  • Financial statement: an audited, reviewed or compiled statement prepared by a CPA (or a board-approved licensed public accountant), no more than one year old. Cash-basis and tax-basis statements and deficits aren’t accepted.
  • Minimum financials: net worth and working capital of at least $10,000 each. A bank line of credit can raise working capital up to your net worth after you meet the minimums.
  • Experience and references: the board reviews your work experience in each classification you request. You also need three reference forms from licensed general contractors, registered architects or engineers, or other persons the board accepts, covering commercial or industrial work you completed.
  • Insurance and registration: proof of current liability insurance with the board listed as certificate holder, and (for entities) current Alabama Secretary of State registration.

  6. Get licensed and renew every yearThe license runs 12 months. Renewal is $200, with a $50 late penalty if you renew more than 90 days after expiration. Put your license number on every bid, proposal and contract.

Quick answers

Do I need a license for a $75,000 job?

Not from this board. Since October 1, 2024, the license is required when the cost of the undertaking is $100,000 or more. Swimming pool work over $5,000 is the exception.

How is my bid limit set?

By a formula in the law: no more than 10 times your net worth or working capital, whichever is less, from your latest CPA financial statement. The letter on your license shows the limit: A up to $100,000, B $250,000, C $500,000, D $1,000,000, E $3,000,000, and U unlimited.

Does Alabama accept the NASCLA exam?

Yes. For Building Construction (Commercial), PSI gives the NASCLA exam as Alabama’s trade exam, and NASCLA lists both the General Contractors Board and the Home Builders Licensure Board as participating agencies. You still pass Alabama’s Business and Law exam.

Is there reciprocity?

The board has reciprocity with Arkansas, Louisiana, Mississippi, North Carolina and Tennessee. You must be licensed for 1 year in the same classification, and your qualifier must be the same person. Only the trade exam is waived. You still take Business and Law.

Do subcontractors take the exam?

No. Subcontractors on undertakings of $100,000 or more under contract to a general contractor need a license, but they don’t sit for an exam, have no bid limit and pay half the fees. They can bid before they’re licensed but must be licensed before starting work.

What changed on October 1, 2026?

Act 2026-396 added exemptions for residential swimming pools and for certain routine or regular maintenance, repair, cleaning and facility support work. The board says to ask it about specific projects before you bid.
