Authorizes construction of fixed works requiring specialized engineering knowledge and skill, including irrigation, drainage, water power, water supply, flood control, inland waterways, harbors, docks, shipyards, dams, hydroelectric projects, levees, railroads, highways, tunnels, airports, sewers, bridges, pipelines, parks, refineries, and power plants.

Does not cover

Does not authorize work under a Class B General Building Contractor license or any specialty (C) classification unless incidental to the engineering project.

Hiring tip

General engineering projects such as grading, paving, and utility work typically require city or county permits. Before hiring, confirm the contractor carries adequate liability insurance for the scope of work and request a written contract that includes project timeline, payment schedule, and warranty terms.

A California contractor license is generally required when a project costs $1,000 or more in combined labor and materials, requires a building permit, or uses additional workers. Small jobs cannot be split from a larger project to qualify for the exemption. Read the CSLB requirements.
