Quick Answer: To choose a general contractor in San Jose in 2025: (1) Verify their CSLB license at cslb.ca.gov — it should be current, in the “B” general building classification or the appropriate specialty class, and have no disciplinary actions; (2) Get at least 3 bids from licensed contractors with written, itemized proposals; (3) Check Google reviews, Yelp, Houzz, and BBB — read the 1-star reviews carefully to understand how the contractor handled disputes; (4) Call 2-3 references from projects similar to yours in size and type; (5) Review the written contract for California-required elements: CSLB license number, payment schedule (no more than 10% or $1,000 initial deposit), completion date, and scope of work; (6) Confirm they carry general liability and workers’ compensation insurance.

General Contractor Selection Checklist — San Jose 2025

  1. Verify CSLB license: Go to cslb.ca.gov, enter the contractor’s name or license number. Confirm: license is current (not expired), classification matches the work scope (B = General Building for full renovations), no disciplinary actions or complaint history in the last 5 years
  2. Get 3+ bids: Verbal estimates are not enough — get itemized written bids. The bids should specify the same scope so you’re comparing apples to apples. The lowest bid is not always the best value.
  3. Check online reputation: Google Business Profile reviews are the most reliable (harder to fake). Look at the contractor’s response to negative reviews — a professional response indicates professionalism. Verify Yelp, Houzz, and BBB as secondary sources.
  4. Call references: Ask to speak with 2-3 past clients with similar projects. Ask specifically: Did the project finish on schedule? Were there surprises in cost? How were disputes handled? Would you hire them again?
  5. Review the contract: California requires written contracts over $500 to include CSLB license number, payment schedule, start and completion dates, scope of work, “Notice to Owner” about mechanic’s liens, and “Right to Cancel” notice
  6. Confirm insurance: Request a Certificate of Insurance showing general liability ($1M minimum) and workers’ compensation. Call the insurance company to verify the policy is active
  7. Verify permit intent: Ask: “Will you pull permits for this project?” The answer should always be yes for any structural, plumbing, or electrical work. A contractor who avoids permits is exposing you to legal and financial risk
