AB 1815: Factory-built housing: building standards and local requirements.

This bill aims to regulate building standards for factory-built housing in California. It prohibits cities, counties, and city-counties from imposing standards exceeding the state minimum building standards, as long as a certain percentage of the project's costs are spent on factory-built housing that meets the department of housing and community development's approval. The bill also expands the scope of a crime and adds to the duties of local officials, making it a state-mandated local program. The bill applies to all cities, including charter cities, and does not require reimbursement for certain costs.
