Summary

(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 Section 4765 governs architectural review in every Riverside HOA. Associations with an architectural review committee (ARC) must provide members with a fair, reasonable, and expeditious procedure for making decisions, deliver decisions in writing with an explanation of the reasons, and offer a procedure to appeal a denial to the board. Annual disclosures to members must describe the review process. Owners proposing exterior changes, paint, roofing, windows, patio covers, solar panels, landscaping, submit plans and must receive a decision within the timeframe in the governing documents.

1 protects Level 2 EV chargers; Civil Code Section 4751 requires HOAs to permit accessory dwelling units on single-family lots consistent with state ADU law; and Civil Code Section 4735 prohibits HOAs from requiring live turf during state drought declarations or banning low-water landscaping. City of Riverside design-review overlays (Mission Inn Historic District, Magnolia Avenue corridor, Mount Rubidoux) add a separate layer requiring a Certificate of Appropriateness through Community and Economic Development, independent of any HOA approval.

Frequently Asked Questions

Can my Riverside HOA reject solar panels?
No. Civil Code 714 limits HOA authority to aesthetic conditions that do not significantly increase cost or decrease performance.
Does my HOA have to approve an ADU?
Yes. Civil Code 4751 requires HOAs to permit ADUs on single-family lots, though reasonable restrictions are allowed.
What if the ARC ignores my application?
File a written appeal to the board. If no timely decision is issued under the governing documents, consult an attorney about alternative dispute resolution.
