Garage Door License in California: Fees, Requirements & Startup Costs
Quick answer: California’s Contractors State License Board licenses covered garage door contracting under C-61/D-28 Doors, Gates and Activating Devices. The researched CSLB fee schedule lists a $450 original application and an initial license fee of $200 for a sole owner or $350 for another business form. A contractor license bond and any business-form-specific requirements are separate; permit work can require a license regardless of price.
When the D-28 classification applies
CSLB’s D-28 scope covers installation, modification, and repair of residential, commercial, and industrial doors, including overhead door assemblies, gates, and operators. A general building contractor may cover garage door work within a qualifying multi-trade project, but a garage-door-focused company should examine the specialty classification. The classification description is the starting point for the service list and advertising language.

Data notes
The D-28 limited specialty requires only the Law and Business exam. The former D-8 Doors and Door Services classification is now part of D-28.

The small-job exemption is narrow
The record explains that the CSLB contractor requirement reaches garage door installation or repair when the aggregate contract price meets the threshold in B&P 7048 or the work requires a building permit. The exemption depends on the whole project’s labor and materials, with other statutory conditions. It disappears if work is split to evade the rule, the person advertises as a contractor, or employees are used. A growing repair business should establish its license path instead of organizing its offer around a narrow exemption.
Qualifying experience and exam
The applicant must document journey-level or comparable experience in the classification; CSLB’s experience guidance explains acceptable roles and education credit. The dataset says C-61 limited specialties take the Law and Business exam without a separate trade exam. Verify scheduling and any waiver with CSLB before committing to a launch date. The qualifying person and business entity named on the application must match the planned operating structure.
Bonds and insurance depend on the entity
The license record includes a contractor license bond and, in some qualifying-person arrangements, another bond. An LLC has additional wage-bond and liability-insurance requirements in the CSLB LLC guidance. Workers’ compensation proof or exemption is part of the license process, with rules changing for later periods. Ask the board and insurer which documents apply to the chosen entity and workforce before comparing business forms solely by filing cost.
CSLB’s bond guidance states the bond amount, but a surety premium is a separate quote. Do not place the full bond face amount in the cash budget as though it were always paid outright. Keep the bond active with the license and monitor any change in the qualifier, ownership, or entity that affects coverage.
Permits, local registration, and renewal
Cities and counties issue building permits and may require a local business license or tax certificate. A door replacement involving structural changes, a new opening, or local wind requirements should be described to the building department before quoting the permit path. Permit-required work needs a licensed contractor under the researched exemption rule. New wiring for an opener also calls for a scope check outside the door classification.
The initial CSLB license spans a renewal period in the record. Renewal fees differ by business form and active status, so the owner should record the correct category after issuance. Check active license status, bond, and workers’ compensation records before advertising and again when renewing. The trade license overview places California beside the other covered states.
Put authorization into the launch plan
Enter the application and license fees from the current CSLB schedule, then add quotes for the bond premium, coverage, vehicle, tools, and parts. A new company planning door installations also needs cash for ordered products and labor before final collection. Use the state preset below and the garage door startup guide to test that timing.
