CA AB557

Plans and specifications for factory-built housing approved by the Department of Housing and Community Development must be approved by unit serial number, allowing reuse in subsequent development projects within the same triennial building code cycle

Approved factory-built housing plans may be used in subsequent triennial building code cycles if no modifications have been made to building standards relating to factory-built housing since the initial approval

The department and design approval agencies must limit their review of new plans to only the portions that have not already been approved for use in that triennial building code cycle, reducing redundant reviews

Violations of these provisions constitute a misdemeanor, expanding the scope of existing criminal penalties under the California Factory-Built Housing Law

The Legislature declares this addresses a statewide housing shortage concern and applies to all cities, including charter cities, overriding local municipal authority on this matter
