Common questions

Answers to what homeowners ask most

California's contractor laws are specific and powerful. Here's what most people want to know first.

See all FAQs →
What can I do if a contractor did bad work on my home?
You have several options: demand in writing that the contractor return to fix defects, file a complaint with the CSLB, pursue the contractor in small claims court for amounts up to $12,500, or hire a construction attorney to send a formal demand letter or file a lawsuit. Document everything before taking any step.
Can I sue a contractor for bad workmanship in California?
Yes. California law allows homeowners to bring claims for breach of contract, negligence, and violation of the Contractors State License Law. If the contractor is licensed, you may also file a claim against their $25,000 contractor bond. The statute of limitations is generally 4 years for written contracts and 2 years for oral contracts from substantial completion.
What if my contractor took my money and disappeared?
A contractor who takes money and abandons a project may be guilty of contractor fraud under California Penal Code §532 and BPC §7160, which carries civil penalties of 3× your actual damages. File a police report, file a CSLB complaint immediately, and consult a construction attorney. Full guide →
How do I file a complaint against a contractor in California?
Visit cslb.ca.gov and complete the online complaint form. You will need the contractor's license number, contact information, a description of the problem, and copies of your contract and payment records. The CSLB can investigate, order restitution, and suspend or revoke the license — at no cost to you. Full guide →
Do I need an attorney to deal with a bad contractor?
For disputes under $12,500 you may handle the matter yourself in small claims court. For larger claims, complex construction defects, or situations involving unlicensed contractors or fraud, an attorney significantly improves outcomes. Bay Legal PC offers free consultations — there is no cost to understand your options.
