AB 738 California Assembly · 2025-2026 Regular Session

Energy: building standards: photovoltaic requirements.

Summary
Existing law authorizes the State Energy Resources Conservation and Development Commission to prescribe, by regulation, lighting, insulation, climate control system, and other building design and construction standards that increase efficiency in the use of energy and water for new residential and new nonresidential buildings, and energy and water conservation design standards for new residential and new nonresidential buildings. Pursuant to this authority, the commission has adopted regulations requiring solar-ready buildings and for the installation of photovoltaic systems meeting certain requirements for low-rise residential buildings built on or after January 1, 2020. This bill would, until January 1, 2028, require residential construction intended to repair, restore, or replace a residential building damaged or destroyed as a result of a disaster in an area in which a state of emergency has been proclaimed by the Governor to comply only with the requirements regarding photovoltaic systems pursuant to those regulations, if any, that were in effect at the time the damaged or destroyed building was originally constructed and would prohibit that construction from being required to comply with any additional or conflicting photovoltaic system requirements in effect at the time of repair, restoration, or replacement. The bill would only apply to the construction of a building if certain conditions are met with respect to the building owner's income and insurance coverage and to the location and square footage of the construction. Because a local agency would be required to determine whether any older applicable photovoltaic requirements are met, this bill would impose a state-mandated local program. 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 no reimbursement is required by this act for a specified reason.

What changed between versions

09/15/25 - Enrolled AB738 · 1 edit
MINOR
No substantive policy changes were made between these two versions. The difference is entirely in presentation format: the enrolled version uses traditional legislative document formatting with page numbers and headers, while the new version is a web page rendering of the same bill text from the California legislature website.
TECHNICAL

The bill text was reformatted from a traditional legislative document layout (with page numbers, running headers, and formal signature blocks) into a web page format with navigation menus, metadata fields, and a different visual structure. The actual statutory language of Section 25402.18 and the reimbursement provision in Section 2 are unchanged.
