A home improvement contract must disclose the contractor's license number primarily so that the homeowner can:

Explanation

The license number is how the homeowner reaches the CSLB record: whether the license is active, what classification it covers, the bond and workers' compensation on file, and any disciplinary or complaint history — all checkable before work starts. It says nothing about the contractor's tax liability or profit margin, which live in the contractor's own books. And a permit is pulled by the licensed contractor or by the owner as owner-builder; a homeowner cannot apply in the contractor's name just because the number appears in the contract.
