AB 2058: California Factory-Built Housing Law.
What AB 2058 does, verified October 1, 2026
This bill aims to reform the California factory-built housing law by changing the inspection and permitting process for factory-built housing. The law requires local enforcement agencies to inspect and enforce the installation of factory-built housing, but the bill would instead allow a first user to choose between a local enforcement agency and a quality assurance agency, which would be supervised by the state department. This change would reduce the burden on local agencies and make the process more efficient. The bill would also limit the inspection fee for local enforcement agencies to 50% of the equivalent fee for nonfactory-built housing and prohibit them from charging a fee if a quality assurance agency is used.

LEGISLATIVE COUNSEL'S DIGEST
AB 2058, Harabedian. California Factory-Built Housing Law.
(1) Existing law, the California Factory-Built Housing Law, generally regulates the design, manufacture, and installation of factory-built housing and defines terms for its purposes. The law authorizes the Department of Housing and Community Development, among other things, to regulate quality assurance agencies to perform inspections of factory-built housing manufacturers. The law requires a local enforcement agency, among other things, to enforce and inspect the installation of factory-built housing. The law provides that any person who violates any of its provisions and other specified law is guilty of a misdemeanor, as specified.
This bill would revise these provisions, among other things, to authorize a quality assurance agency to also perform an installation inspection of factory-built housing, at the choice of a first user, after the department adopts regulations regarding the requirements for a quality assurance agency to perform these inspections. The bill would require the department to adopt those regulations by January 1, 2029. The bill would set the maximum fees that a local enforcement agency is authorized to impose for the inspection or permitting of factory-built housing, and prohibit a local enforcement agency from imposing fees under certain circumstances. The bill would prohibit a quality assurance agency or a local enforcement agency from disassembling, damaging, or destroying factory-built housing while inspecting the installation. The bill would make conforming changes and define terms for its purposes.
By increasing the duties of local officials, and by expanding the scope of a crime, this bill would impose a state-mandated local program.
(2) The bill would include findings that changes proposed by this bill address a matter of statewide concern rather than a municipal affair and, therefore, apply to all cities, including charter cities.
(3) The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.
This bill would provide that with regard to certain mandates no reimbursement is required by this act for a specified reason.
With regard to any other mandates, this bill would provide that, if the Commission on State Mandates determines that the bill contains costs so mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above.
The people of the State of California do enact as follows:

(2) Notwithstanding paragraph (1), a local enforcement agency may impose an inspection fee for the inspection of the installation of factory-built housing that exceeds 50 percent of the equivalent inspection fee for nonfactory-built housing if the local enforcement agency, as part of a written finding and an adopted resolution or ordinance, provides substantial evidence of the reasonable cost to conduct the inspections.
(c) If a first user chooses to have a quality assurance agency inspect the installation of factory-built housing, the local enforcement agency shall not charge an inspection fee, but may charge fees for inspection of sitework for items not related to the installation of the factory-built housing, including, but not limited to, grading, foundations, and landscaping other nonfactory-built housing.

SEC. 6.
The Legislature finds and declares that the provision of adequate housing, in light of the severe shortage of housing at all income levels in the state, is a matter of statewide concern and is not a municipal affair as that term is used in Section 5 of Article XI of the California Constitution. Therefore, Sections 1, 2, 3, 4, and 5 of this act amending Sections 19976.05, 19991, and 19992 of, and adding Sections 19992.1 and 19992.2 to, the Health and Safety Code, respectively, apply to all cities, including charter cities.SEC. 7.
