California Demolition

California demolition contractor license guide

California demolition contractors use CSLB's C-21 Building Moving/Demolition Contractor classification. This page connects structure moving, structure removal, demolition, foundations, and retained-structure exclusions to official CSLB sources.

The short answer

California demolition contractors should review CSLB's C-21 Building Moving/Demolition Contractor classification before selling structure raising, lowering, cribs, underpinning, moving, removal, or demolition work. CSLB's C-21 description does not include alterations, additions, repairs, or rehabilitation of permanently retained portions of structures.

Who this applies to

  • California contractors raising, lowering, cribs, underpinning, demolishing, moving, or removing structures and foundations should review C-21.
  • Demolition can overlap with general contracting, excavation, asbestos/lead abatement, structural engineering, utilities, hauling, permits, and hazardous-material handling.
  • Homeowners and contractors should verify CSLB license status before structure removal, interior demolition, foundation removal, or demolition subcontracting.

Practical application path

  1. Read CSLB's C-21 classification page before advertising demolition or structure-moving services.
  2. Confirm whether the planned work is C-21 demolition, general contracting, excavation, asbestos/lead abatement, hauling, or retained-structure repair.
  3. Identify the qualifying individual and gather verifiable demolition or structure-moving experience documentation.
  4. Follow CSLB's application, exam, fingerprinting, bond, and issuance instructions.
  5. Confirm permits, utility disconnects, hazardous-material rules, engineering, hauling, disposal, and neighbor/property protection before starting jobs.

Watchouts before you sell the work

  • Demolition quotes should separate permits, utility disconnects, dust control, debris hauling, recycling/disposal, hazardous materials, and site protection.
  • C-21 demolition is not the same as remodeling or repairing permanently retained portions of a structure.
  • Asbestos, lead paint, mold, structural instability, underground utilities, and foundation removal can change the scope and compliance path.
