Summary

HOAs in Riverside County typically operate Architectural Review Committees (ARCs) under Davis-Stirling Act §4765. Owners must submit plans for exterior changes, and the ARC must respond in writing within a reasonable time with reasoning. Solar, EV charging, and low-water landscaping have state-mandated approval protections.

City-specific rules exist: Moreno Valley, Palm Springs, Murrieta, Corona, Temecula, and Riverside have their own architectural review rules that differ from Riverside County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

(a) This section applies if the governing documents require association approval before a member may make a physical change to the member's separate interest or to the common area. In reviewing and approving or disapproving a proposed change, the association shall satisfy the following requirements: (1) The association shall provide a fair, reasonable, and expeditious procedure for making its decision. The procedure shall be included in the association's governing documents. The procedure shall provide for prompt deadlines. The procedure shall state the maximum time for response to an application or a request for reconsideration by the board. (2) A decision on a proposed change shall be made in good faith and may not be unreasonable, arbitrary, or capricious. (3) Notwithstanding a contrary provision of the governing documents, a decision on a proposed change may not violate any governing provision of law, including, but not limited to, the Fair Employment and Housing Act (Part 2.8 (commencing with Section 12900) of Division 3 of Title 2 of the Government Code), or a building code or other applicable law governing land use or public safety. (4) A decision on a proposed change shall be in writing. If a proposed change is disapproved, the written decision shall include both an explanation of why the proposed change is disapproved and a description of the procedure for reconsideration of the decision by the board. (5) If a proposed change is disapproved, the applicant is entitled to reconsideration by the board, at an open meeting of the board. [...] (c) An association shall annually provide its members with notice of any requirements for association approval of physical changes to property. The notice shall describe the types of changes that require association approval and shall include a copy of the procedure used to review and approve or disapprove a proposed change.

Full Breakdown

California Civil Code §4765 (Davis-Stirling) governs HOA architectural review. Associations must maintain a fair, reasonable, and expeditious procedure for reviewing and approving applications for physical changes to a member's separate interest or exclusive-use common area. Decisions must be made in good faith and not arbitrarily or capriciously. Denials must be in writing with specific reasons and a description of the appeal process. Annual reports on applications and decisions must be provided to members. Several categories of improvements have statutory protections that override restrictive HOA rules: solar energy systems (Civ Code §714. Solar Rights Act), electric vehicle charging stations (§4745), low water-usage landscaping and artificial turf (§4735), clotheslines (§4750.10), and personal agriculture gardens (§4750). HOAs may impose reasonable restrictions (aesthetic and safety) but cannot effectively prohibit these installations. Disputes over architectural decisions are subject to Internal Dispute Resolution (§5910) and alternative dispute resolution (§5930) before civil litigation.

Frequently Asked Questions

Can my HOA deny solar panels?
No. Under the Solar Rights Act (Civ Code §714), HOAs cannot prohibit solar: only impose reasonable, non-cost-prohibitive restrictions.
How long does an ARC have to respond?
Davis-Stirling requires a reasonable time; most CC&Rs specify 30-60 days. Silence may be deemed approval per some association rules.
