Who can fix it in California? Handyman and contractor license rules

Checked October 20, 2026 against California law and state agency pages · General information, not legal advice

The short answer: In California, a worker with no state license may only take a job that costs less than $1,000 in total. The job must not need a building permit. The worker must work alone.

“This chapter does not apply to a work or operation on one undertaking or project by one or more contracts if the aggregate contract price for labor, materials, and all other items is less than one thousand dollars ($1,000), that work or operation being considered of casual, minor, or inconsequential nature, and the work or operation does not require a building permit.” — Cal. Bus. & Prof. Code § 7048(a)
