Hiring tip

Building moving and demolition requires specialized permits and may involve asbestos or lead paint abatement. Verify the contractor carries adequate liability insurance and has experience with local permitting requirements.

A California contractor license is generally required when a project costs $1,000 or more in combined labor and materials, requires a building permit, or uses additional workers. Small jobs cannot be split from a larger project to qualify for the exemption. Read the CSLB requirements.
