California Construction Law: What You Need to Know

California is Different

California has some of the most detailed construction regulations in the country. Understanding them protects your interests.

Contractor Licensing

All contractors performing work over $500 must hold a valid CSLB license. Working without a license is a crime.

Contract Requirements

All home improvement contracts over $500 must:

• Be in writing
• Include specific disclosures
• Provide cancellation rights
• Limit deposits

Deposit Limits

Down payments are limited to 10% of contract price or $1,000, whichever is less.

Mechanics Liens

Contractors, subcontractors, and suppliers can file liens for unpaid work. Preliminary notices are required.

Warranty Requirements

California implies certain warranties in construction contracts, including fitness for purpose.

How Bidroom Helps

Bidroom generates California-compliant contracts with all required notices and disclosures built in.
