  1. AThe contractor's Social Security number
  2. BThe homeowner's tax identification number
  3. CThe contractor's license number and CSLB registration information

Show answer & explanation

Correct answer: C. The contractor's license number and CSLB registration information

California law requires the contractor's license number and CSLB information to appear on the contract so homeowners can verify licensing status; personal identifiers like Social Security numbers or notarization are not required.

Why the other options are wrong

  • A. Social Security numbers are private and not a contract requirement.
  • B. The homeowner's tax ID has no relevance to contract requirements.
  • D. Notarization is not required for home improvement contracts.

Required Contract Disclosures
