The specialty license lets you install, maintain, repair, alter, or extend residential and commercial garage doors and their hardware. The 120-volt operator circuit is included in your contract but must be subcontracted to a licensed electrical contractor.
1. Confirm the scope is right for you
The Garage Door Installation Specialty Contractor license covers the full door system — sections, tracks, counterbalance (torsion or extension springs), cables, drums, and operators — plus the hardware and safety devices that go with them. It does not cover structural framing of the garage or running new electrical branch circuits.
2. Meet the state's requirements
Beyond passing the exam, the DBPR requires applicants to meet experience, financial-responsibility, and insurance requirements and to pass a background check. Requirements change over time, so verify the current list with the DBPR before you apply.
3. Pass the trade-knowledge exam
The trade-knowledge exam is a computer-based, open-book test of 55 questions with a 2.5-hour time limit, and you need 70% to pass. Questions are drawn from seven official content areas, weighted roughly like this:
- Introduction & Regulations — 9%
- Tools, Equipment & Materials — 15%
- Technical Knowledge — 27%
- Installation Procedures — 24%
- Repair & Maintenance — 13%
- Electrical Work & Safety — 5%
- Health & Safety — 7%
Because the exam is open book, fast recall of where an answer lives matters as much as memorizing it. Practicing by content area builds both.
Open book ≠ easy. Technical Knowledge and Installation Procedures together are more than half the exam — that's where to spend your study time.
