California · 2025-2026 Regular Session · upper

Quick answers

Did CA SB 710 pass?

Yes. CA SB 710 has been enacted into law as of 2025-10-03. Latest recorded action (2025-10-03): Chaptered by Secretary of State. Chapter 328, Statutes of 2025.

What is CA SB 710 about?

The California Constitution generally limits the maximum rate of ad valorem tax on real property to 1% of the full cash value of the property and defines "full cash value" for these purposes as the appraised value of real property when purchased, newly constructed, or a change in ownership has occurred after the 1975 assessment. Pursuant to constitutional authorization, existing property tax law excludes from the definition of "newly constructed" for these purposes the construction or addition of any active solar energy system, as defined, through the 2025–26 fiscal year. Under existing property tax law, this exclusion remains in effect only until there is a subsequent change in ownership, but an active solar energy system that qualifies for the exclusion before January 1, 2027, continues to receive the exclusion until there is a subsequent change in ownership. Existing law repeals these exclusion provisions on January 1, 2027. This bill would make a technical change to the existing active solar energy system exclusion by instead making the repeal date of January 1, 2027, the date the exclusion becomes inoperative. This bill would incorporate additional changes to Section 73 of the Revenue and Taxation Code proposed by AB 1516 to be operative only if this bill and AB 1516 are enacted and this bill is enacted last.
