AB 2058 California Assembly · 2025-2026 Regular Session

California Factory-Built Housing Law.

Summary
(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.

MODERATE
The August 21 Senate amendment to AB 2058 makes several targeted changes to the factory-built housing inspection framework. Most significantly, it requires local enforcement agencies to affirmatively offer installation inspection services and explicitly mandates that they enforce installation of factory-built housing, while narrowing the role of quality assurance agencies from 'enforce and inspect' to simply 'inspect.' The amendment also removes the appropriation finding and clarifies terminology throughout.
Scope change
The bill's scope is slightly narrowed for quality assurance agencies (limited to inspection rather than enforcement) while simultaneously expanding obligations on local enforcement agencies (must offer inspection services and must enforce installation). The overall framework remains the same: first users get a choice between local and state-supervised private inspection, but the roles of each party are more precisely defined.
REQUIREMENT

Section 19992 now explicitly requires local enforcement agencies to enforce the installation of factory-built housing, adding an affirmative duty that was previously only implied.

Section 19992.1(a)(1) now requires a local enforcement agency to affirmatively offer inspection of factory-built housing installation, and clarifies that the first user's choice between a local agency or quality assurance agency only becomes available after the department adopts regulations under subdivision (d).

SCOPE

Throughout Section 19992.1, the role of quality assurance agencies is narrowed from 'enforce and inspect' to simply 'inspect,' removing their enforcement authority over installation.

DEFINITION

The definition of 'quality assurance agency' in Section 19976.05 is refined from 'onsite inspections of factory-built housing' to 'onsite installation inspections of factory-built housing,' making the scope more specific.

FISCAL

The appropriation finding was changed from 'yes' to 'no,' removing the bill's appropriation designation.

TECHNICAL

Section 19992.2 changes references from 'factory-built housing' to 'factory-built housing structure' in the permitting fee cap provisions, clarifying that the 50 percent fee cap applies to the structure specifically.
