When Is a California HOA Rule Unenforceable?

Not every rule a California board announces is automatically enforceable. The main state law governing California associations, the Davis-Stirling Common Interest Development Act (Civil Code § 4000 and following), spells out what makes an operating rule valid, how a rule has to be adopted, which activities the governing documents cannot ban, and what has to happen before a member is fined. A rule that misses one of those marks is open to question. For your specific situation, a licensed California attorney is the right resource. This is general information, not legal advice.

Who Davis-Stirling covers

The act applies to "common interest developments," which Civ. Code § 4100 defines as "(a) A community apartment project. (b) A condominium project. (c) A planned development. (d) A stock cooperative." So it reaches both single-family planned communities and condominiums. Under § 4201, it does not apply to "a real property development that does not contain common area." Davis-Stirling does not operate alone: the association's declaration (CC&Rs), articles, and bylaws, California's nonprofit corporation law for associations organized as nonprofit corporations, and federal law all apply as well.

The five tests for an operating rule

Davis-Stirling defines an "operating rule" as "a regulation adopted by the board that applies generally to the management and operation of the common interest development or the conduct of the business and affairs of the association" (Civ. Code § 4340(a)). Section 4350 then sets the bar every such rule has to clear. A rule "is valid and enforceable only if all of the following requirements are satisfied":

• "(a) The rule is in writing."
• "(b) The rule is within the authority of the board conferred by law or by the declaration, articles of incorporation or association, or bylaws of the association."
• "(c) The rule is not in conflict with governing law and the declaration, articles of incorporation or association, or bylaws of the association."
• "(d) The rule is adopted, amended, or repealed in good faith and in substantial compliance with the requirements of this article."
• "(e) The rule is reasonable."

A verbal directive, a rule outside the authority that the law and the governing documents give the board, or a rule that contradicts the CC&Rs does not meet § 4350. The statute also sets a hierarchy for conflicts. Under § 4205(a), "[t]o the extent of any conflict between the governing documents and the law, the law shall prevail," and under § 4205(d), when operating rules conflict with the bylaws, articles, or declaration, those higher documents prevail.

Restrictions written into the declaration itself are measured differently. Under § 5975(a), "[t]he covenants and restrictions in the declaration shall be enforceable equitable servitudes, unless unreasonable." So a CC&R restriction carries its own reasonableness limit, separate from the five-part test for board-adopted rules.

How a rule has to be adopted

Test (d) ties validity to the adoption procedure. That procedure applies to rules on the subjects listed in § 4355(a), including use of the common area, "[u]se of a separate interest, including any aesthetic or architectural standards," member discipline and fine schedules, dispute-resolution procedures, review of proposed physical changes, and election procedures. It does not apply to things like common-area maintenance decisions, decisions on a single specific matter, or setting assessment amounts (§ 4355(b)).

For covered rules, § 4360(a) requires the board to give general notice "at least 28 days before making the rule change," including "the text of the proposed rule change and a description of the purpose and effect of the proposed rule change." The decision "shall be made at a board meeting, after consideration of any comments made by association members" (§ 4360(b)), and notice of the adopted change goes out within 15 days (§ 4360(c)). The only shortcut is an emergency rule to address "an imminent threat to public health or safety" or "an imminent risk of substantial economic loss to the association"; an emergency rule lasts at most 120 days and "may not be readopted under this subdivision" (§ 4360(d)).

Members also have a direct check. Under § 4365(a), owners of "5 percent or more of the separate interests may call a special vote of the members to reverse a rule change." The written request has to be delivered within 30 days after the association gives general notice of the change, and the vote is held 35 to 90 days after a proper request (§ 4365(b)). A majority of a quorum can reverse the rule unless the declaration or bylaws require more, and a reversed rule "may not be readopted for one year" (§ 4365(d), (f)).

Activities a rule cannot ban

Some rules fail no matter how carefully they were adopted, because Davis-Stirling and the Civil Code protect specific uses:

• U.S. flag — "no governing document shall limit or prohibit, or be construed to limit or prohibit, the display of the flag of the United States" on or in a member's separate interest or exclusive use common area, except for public health or safety (§ 4705(a)). See Can My HOA Ban the American Flag?
• Noncommercial signs and flags — the governing documents "may not prohibit posting or displaying of noncommercial signs, posters, flags, or banners" on or in a separate interest, except for public health or safety or where the display would violate law, though an association may prohibit signs and posters over nine square feet and flags or banners over 15 square feet (§ 4710(a), (c)). See Can My HOA Ban Political Signs?
• Religious items — no governing document may limit or prohibit "the display of one or more religious items on the entry door or entry door frame" (§ 4706(a)).
• Pets — the governing documents cannot prohibit an owner "from keeping at least one pet within the common interest development, subject to reasonable rules and regulations of the association," and a new limit on the number of pets does not reach a conforming pet the owner already keeps (§ 4715(a), (c)). The section applies to governing documents entered into or changed on or after January 1, 2001 (§ 4715(e)). See Can My HOA Ban My Pet?
• Solar — a provision that "effectively prohibits or restricts the installation or use of a solar energy system is void and unenforceable" (§ 714(a)). Reasonable restrictions are allowed: ones that do not significantly increase the system's cost or significantly decrease its efficiency or specified performance, or that allow a comparable alternative system; for photovoltaic systems, the statute ties "significantly" to "one thousand dollars ($1,000) over the system cost" or an efficiency decrease "exceeding 10 percent" (§ 714(b), (d)). If an association (other than a public entity) does not deny an application in writing within 45 days, it is deemed approved, unless the delay comes from a reasonable request for more information (§ 714(e)). See Can My HOA Ban Solar Panels?
• EV charging — a provision that "effectively prohibits or unreasonably restricts the installation or use of an electric vehicle charging station" in an owner's unit or designated parking space "is void and unenforceable"; an application not denied in writing within 60 days is deemed approved, with the same information-request exception (§ 4745(a), (e)).
• Antennas and satellite dishes — restrictions that effectively prohibit or restrict a video or television antenna are "void and unenforceable" as applied to one with "a diameter or diagonal measurement of 36 inches or less," subject to reasonable restrictions such as advance application and notice (§ 4725(a), (b)).
• Drought-friendly landscaping — a provision is "void and unenforceable" if it prohibits, or has the effect of prohibiting, low water-using plants or artificial turf (§ 4735(a)), and an association "shall not impose a fine or assessment" for cutting back watering during a declared drought emergency, with a narrow recycled-water exception (§ 4735(c), (d)). A requirement to pressure wash during a declared drought emergency is also void (§ 4736(a)).
• Fire-retardant roofing — in a very high fire severity zone, the governing documents "shall allow for at least one type of fire retardant roof covering material" meeting Health and Safety Code § 13132.7 (§ 4720(b)).
• Selling a home — "[a]ny provision of a governing document that arbitrarily or unreasonably restricts an owner's ability to market the owner's interest" is void, and an association may not charge a marketing fee above its "actual or direct costs" or require an exclusive broker (§ 4730(a), (b)).
• Renting — the governing documents cannot prohibit, effectively prohibit, or unreasonably restrict renting, and a rental cap cannot go below "25 percent of the separate interests," though rentals of "30 days or less" can still be banned (§ 4741(a)–(c)). Timing matters too: under § 4740(a), an owner is not subject to a rental prohibition "unless that governing document, or amendment thereto, was effective prior to the date the owner acquired title," and § 4739(a) protects renting part of an owner-occupied home for more than 30 days. See Can My HOA Prevent Me From Renting My Home?
• Backyard gardens and clotheslines — provisions that effectively prohibit or unreasonably restrict "personal agriculture" in a backyard, or a clothesline or drying rack in a backyard, are void, in yards designated for the owner's exclusive use (§§ 4750, 4753).
• ADUs — in a planned development, a provision that effectively prohibits or unreasonably restricts an accessory dwelling unit or junior ADU on a lot zoned for single-family use that meets state ADU law is void and unenforceable (§ 4751(a)). Effective January 1, 2027, AB 956 (Stats. 2026, ch. 791) extends this to a lot "zoned to allow single-family residential use."
• Cooling systems — Effective January 1, 2027, AB 1684 (Stats. 2026, ch. 887) adds § 4738, under which a provision of the governing documents or architectural guidelines "shall be void and unenforceable if the provision prohibits or restricts the installation, upgrade, replacement, or use of a cooling system that complies with all applicable state and local building codes" (§ 4738(a)). Window and portable air conditioners, evaporative coolers, and heat pumps can all qualify (§ 4738(d)). For a member's separate interest, the association also cannot charge a fee, require a specific system or contractor, or require a system's removal, unless it establishes that the work would violate law or that a required permit was not granted (§ 4738(c)). Where a system affects the common area or an exclusive use common area, the association can still make the owner responsible for repairing damage the system causes, require a licensed contractor (except for window, portable, or evaporative units and other systems that need no local building permit), and require disclosure to buyers (§ 4738(e)). A willful violation carries actual damages and a civil penalty "not to exceed two thousand dollars ($2,000)," and a member who wins an enforcement suit is entitled to reasonable attorney's fees and court costs (§ 4738(f)).
• Replacement windows — Effective January 1, 2027, SB 908 (Stats. 2026, ch. 787) adds § 4754, making "void and unenforceable" a governing-document provision that "effectively prohibits or restricts the owner of a separate interest from completing a residential window replacement project" for the owner's separate-interest windows, exclusive use common area windows, or common-area windows designed to serve only that owner's unit (§ 4754(a)). A covered project only replaces existing windows "with windows of the same size and in the same location," without alterations beyond those needed to install them, in compliance with the California Building Standards Code, including the Energy Code (Gov. Code § 65850.73(b)(2), added by the same bill). Reasonable installation restrictions survive, as do reasonable aesthetic restrictions in multifamily buildings of more than 20 units without townhomes, if together they do not raise the project's cost or cut its energy efficiency by more than 10 percent compared with the project as originally proposed (§ 4754(b), (f)). For exclusive-use or common-area windows, the association requires approval but must give it if the owner agrees in writing to terms including a licensed contractor, required permits, and paying the installation costs (§ 4754(e)). Where approval is required, an application not approved or disapproved in writing "within 45 days from the date of receipt of the application" is deemed approved, unless the delay comes from a request for required information the owner did not provide (§ 4754(d)(2)).

Most of these sections still leave room for reasonable rules about placement, size, or process, so the line is usually between a ban (or a rule that works like one) and a reasonable limit.

Fines require a schedule and a hearing

A valid rule still does not produce a valid fine unless the association follows Davis-Stirling's discipline process. Under § 5850(a), an association that fines members has to adopt and distribute a schedule of monetary penalties, and "[m]onetary penalties shall be reasonable." Since June 30, 2025, § 5850(c) limits a fine to the lesser of the scheduled amount or "[o]ne hundred dollars ($100) per violation," unless the violation "may result in an adverse health or safety impact on the common area or another association member's property" and the board makes a written finding at an open meeting (§ 5850(d)). "A late charge or interest shall not be charged to a member for a monetary penalty" (§ 5850(e)).

Before discipline, § 5855(a) requires written notice "at least 10 days prior to the meeting," and § 5855(c) gives the member "the opportunity to cure the violation prior to the meeting"; the board "shall not impose discipline" if the member cures beforehand. The board must deliver its written decision within 14 days (§ 5855(f)), and if the member and board still disagree, the member may request internal dispute resolution (§ 5855(d)). Most pointedly, under § 5855(g), a disciplinary action "shall not be effective against a member unless the board fulfills the requirements of this section." See California HOA Fines and Hearings.

Selective enforcement

A rule applied to one owner but not to similarly situated neighbors raises a fairness question. None of the sections quoted here sets a specific consistency standard, but § 4350(e) requires an operating rule to be "reasonable," § 5975(a) makes declaration restrictions enforceable "unless unreasonable," and how an association has treated the same conduct by others can become part of a dispute over a rule. The association's own records and minutes are usually where that pattern surfaces.

Where federal and state law overrides a rule

Beyond Davis-Stirling, other law limits what any rule can do:

• Fair housing — the federal Fair Housing Act and California's fair housing law (Gov. Code § 12955) bar housing discrimination, including on the basis of disability, and the federal act treats "a refusal to make reasonable accommodations in rules, policies, practices, or services" as discrimination against a person with a disability when such accommodations "may be necessary to afford such person equal opportunity to use and enjoy a dwelling" (42 U.S.C. § 3604(f)(3)(B))
• The U.S. flag — under the federal Freedom to Display the American Flag Act of 2005, a condominium, cooperative, or residential real estate management association "may not adopt or enforce any policy" that would restrict or prevent a member from displaying the U.S. flag on residential property the member owns or has exclusive use of, subject to "any reasonable restriction pertaining to the time, place, or manner of displaying the flag" needed to protect a substantial association interest (Pub. L. 109-243, §§ 3, 4)
• Antennas and dishes — the FCC's OTARD rule, 47 C.F.R. § 1.4000, reaches any "homeowners' association rule or similar restriction" that impairs installing or using qualifying satellite and broadcast antennas, generally one meter or less, on property in the owner's exclusive use or control

A rule that collides with any of these is not saved by being in the governing documents.

What people generally do

When a California rule is in question, the points that commonly matter are:

• Whether the rule is in writing and traces back to authority in the declaration, articles, bylaws, or statute, as § 4350 requires.
• Whether a covered rule went through the 28-day notice and board-meeting process in § 4360, and whether a member reversal vote under § 4365 is still within its 30-day window.
• Whether the rule cuts into one of the protected uses above.
• Whether any fine followed the § 5850 schedule and cap and the § 5855 notice, cure, and hearing steps.
• Evidence of how the rule has been enforced against others.
• In a lawsuit to enforce the governing documents, "the prevailing party shall be awarded reasonable attorney's fees and costs" (§ 5975(c)). That cuts both ways: the fee award goes to whichever side prevails, owner or association.
• For a disputed rule or fine, internal dispute resolution and a licensed California attorney are the available resources, and more state-specific guides are on the California HOA law hub.

Frequently asked questions

Does a California HOA rule have to be reasonable?

Yes. Civil Code § 4350(e) makes reasonableness one of five requirements for an operating rule to be "valid and enforceable," alongside being in writing, within the board's authority, consistent with the law and governing documents, and adopted in good faith with substantial compliance with the rule-making procedure. Restrictions in the declaration itself are enforceable "unless unreasonable" under § 5975(a).

Can a California HOA change its rules without telling owners?

Not for the rule subjects listed in § 4355(a). Section 4360(a) requires general notice at least 28 days before the change, with the text and a description of its purpose and effect, and the decision has to be made at a board meeting after considering member comments. The exception is an emergency rule for an imminent threat to health or safety or substantial economic loss, which lasts no more than 120 days.

Can California homeowners overturn a new HOA rule?

Section 4365 lets owners of 5 percent or more of the separate interests call a special vote to reverse a rule change, if the written request is delivered within 30 days after the association gives general notice of the change. A majority of a quorum can reverse it (or a higher percentage if the declaration or bylaws require), and a reversed rule cannot be readopted for one year, though the board may adopt a different rule on the same subject.

Can a California HOA fine me for breaking a rule?

It can if its governing documents authorize discipline and it follows Davis-Stirling's process: a distributed fine schedule, a cap of $100 per violation in most cases (§ 5850(c)), at least 10 days' written notice of a hearing, a chance to cure first, and a written decision within 14 days (§ 5855). Under § 5855(g), discipline imposed without those steps "shall not be effective against a member."
