Quick Answer: The most common home remodeling scams in San Jose and the Bay Area include: (1) unlicensed contractors offering suspiciously low bids, (2) large up-front payment demands (over 10% or $1,000, whichever is less, is illegal in California), (3) storm chasers targeting roof and structural repairs after earthquakes or storms, (4) contractors who “discover” unexpected problems mid-project to inflate the price, and (5) bait-and-switch — low initial bid replaced by change orders. Always verify CSLB license at cslb.ca.gov before signing.

Frequently Asked Questions
What is the maximum legal down payment for a contractor in California? Under California Business and Professions Code Section 7159, contractors cannot legally demand more than 10% of the total contract price OR $1,000 — whichever is less — as a down payment before beginning work. Any contractor who demands more upfront is violating California law.
How do I report an unlicensed contractor in San Jose? Report unlicensed contractors to the CSLB’s complaint system at cslb.ca.gov or call the CSLB at 1-800-321-CSLB (2752). You can also report to the Santa Clara County District Attorney’s consumer protection division for criminal fraud cases.
What should a valid contractor contract include in California? California law requires contractor contracts to include: contractor’s name, license number, and address; a description of the work; a payment schedule; a start date and estimated completion date; a change order clause; and a notice of the homeowner’s right to cancel within 3 business days (for contracts signed at the homeowner’s home).
