Bill Overview

Analyzed Economic Effects

3 provisions identified: 2 benefits, 0 costs, 1 mixed.

Lower property taxes for home solar

If you install a qualifying active solar energy system, your home is not reassessed for that added value. Qualifying uses include water heating, space conditioning, electricity, process heat, and solar mechanical energy. The exclusion covers panels, batteries, inverters, transfer gear, and spare parts owned for that system. Pipes or ducts used for both solar and other energy count at 75% of value; pool and hot tub heaters do not count. The exclusion lasts until you sell the property. Systems that qualify before January 1, 2027, keep the exclusion after that date until ownership changes.

Savings for first buyers of solar homes

If you are the first buyer of a new home from a builder, you can claim the solar exclusion when the builder did not get it. The assessor lowers your new base year value by the part of your price for the solar system minus any rebates. You must file a claim and provide documents showing the solar portion of the price and all rebates. A claim is timely within three years of purchase; if filed later, it applies starting on that year’s lien date. The three‑year rule starts January 1, 2027. The exclusion remains until you later sell the home.

Coordination rules with another solar law

The law sets backup rules if another solar property‑tax bill (AB 1516) also becomes law. If both laws take effect by January 1, 2026, both change the same code section, and this law is enacted after AB 1516, then the coordinated text (Section 1.5) applies and Section 1 does not take effect. This does not change your tax bill by itself; it only decides which text governs.
