AB 1684 adds Civil Code section 4737 to the Davis‑Stirling Act and removes an association’s power to prohibit or otherwise restrict a homeowner from installing, upgrading, replacing, or using a cooling system in their separate interest. The bill also voids recorded covenants and other transfer instruments that effectively prohibit such installations.
The measure forbids HOAs from charging fees or forcing members to use specific equipment or contractors in connection with cooling systems, while preserving narrow exceptions where the installation would violate law or requires a permit that is not granted. Associations that willfully ignore the statute are exposed to members’ actual damages and a civil penalty up to $2,000, creating a private enforcement pathway and forcing boards and managers to change approval practices and governing documents.
At a Glance
What It Does
The bill makes any clause in governing documents, architectural guidelines, or transfer instruments that restricts installation, replacement, upgrade, or use of a cooling system unenforceable, and it bars associations from imposing fees, mandating specific systems or contractors, claiming rebates, or ordering removal. Exceptions apply only when the installation would violate law or when a required permit is denied.
Who It Affects
Homeowners and members of common interest developments (condominiums, planned developments) and their boards and architectural committees are directly affected. Cooling-equipment sellers and installers, title companies, and permitting authorities also have operational and compliance consequences to manage.
Why It Matters
AB 1684 narrows the scope of architectural control in California common interest developments and shifts responsibility for cooling choices to individual members, raising immediate compliance questions for HOA policies and creating new exposure for associations that continue to enforce bans.

What This Bill Actually Does
AB 1684 inserts a new Section 4737 into the Civil Code under the Davis‑Stirling Act. The provision invalidates any governing-document provision, architectural rule, or policy that prohibits or limits a member’s right to install, upgrade, replace, or use a cooling system in their separate interest.
It also reaches recorded instruments—deeds, contracts, and security instruments—that effectively contain the same prohibition.
The bill specifies a set of concrete prohibitions on associations: they may not charge a fee related to a member’s cooling system installation or use; they may not require a member to use a particular type or brand of equipment or a particular contractor; they may not claim rebates or commissions tied to a member’s purchase; and they may not force removal or block replacement or upgrades. Those restrictions are trimmed back only where the proposed installation would run afoul of federal, state, or local law, or where a required permit from the appropriate authority has been denied.“Cooling system” is defined broadly to include portable and window air‑conditioners, swamp or evaporative coolers, cooling fans, heat pumps, and other technologies that reasonably provide internal cooling benefits, provided the equipment complies with applicable health and safety requirements.
The bill does not create an affirmative duty for associations to pay for installations or to maintain members’ equipment; it removes the right to ban or financially penalize the member for installing the equipment.Enforcement is through a private action: if an association willfully violates the statute, the member may recover actual damages and a civil penalty of up to $2,000. The bill does not create an administrative enforcement mechanism, does not specify attorney’s fees, and leaves implementation details—such as how associations should handle architectural review fees or the interplay with shared systems—to be worked out in practice or litigation.
The Five Things You Need to Know
The bill adds Civil Code §4737(a) to render void any governing document, architectural guideline, or policy that prohibits or restricts installing, upgrading, replacing, or using a cooling system in a member’s separate interest.
Section 4737(b) makes unenforceable any recorded covenant, deed restriction, security instrument, or sale/transfer document that effectively bars a cooling system.
Section 4737(c)(1) expressly bars associations from charging installation-related fees, mandating a specific type of equipment or contractor, claiming rebates tied to a member’s purchase, or forcing removal or preventing an upgrade.
Section 4737(c)(2) allows associations to restrict an installation only if it would violate federal, state, or local law, or if a required permit from the designated permitting authority is not granted.
Section 4737(e) imposes member remedies for willful violations: recovery of actual damages plus a civil penalty not exceeding $2,000.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Voidance of association rules that limit cooling systems
This subsection removes an association’s contractual authority to adopt or enforce any internal rule, guideline, or policy that prohibits or limits a member’s ability to put cooling equipment into their unit. Practically, boards must stop relying on architectural rules to deny approval solely because a proposal adds or modifies cooling equipment; existing rule language that operates as a ban will no longer be enforceable.
Recorded covenants and transfer instruments cannot bar cooling systems
AB 1684 reaches recorded instruments—deeds, covenants, security instruments, and other transfer documents—so homeowners cannot be turned away at closing by a recorded restriction that effectively prohibits cooling equipment. Title companies and sellers will still find the record language, but the statute removes enforceability; the text leaves open how courts will treat recorded language for other legal purposes (e.g., quiet title or disclosure).
Specific prohibitions on association conduct
The statute enumerates association conduct that is forbidden: charging any fee connected to installing or using a cooling system, requiring a member to purchase a particular product or use a particular contractor, taking rebates or commissions from a member’s purchase, or ordering removal or blocking replacement/upgrade. That list constrains both formal board actions and common management practices that monetize or condition homeowner retrofits.
Permits and legal-compliance exceptions
Two narrow exceptions allow an association to lawfully restrict an installation: if the cooling system would violate federal, state, or local law, or if the required permit from the designated permitting authority is not granted. The provision therefore defers to standalone legal and permitting frameworks while stripping associations of independent veto power where those external requirements are satisfied.
Definition of cooling system and remedies for violations
Subdivision (d) gives a nonexclusive list of covered technologies (portable/window units, evaporative coolers, fans, heat pumps, and similar tech) and anchors them to applicable health and safety standards. Subdivision (e) creates the enforcement remedy: willful violations expose the association to actual damages and a civil penalty up to $2,000 payable to the harmed member, establishing a private cause of action rather than an administrative enforcement route.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- HOA members/homeowners — Gains a statutory right to install or replace cooling equipment in their separate interest without facing association bans or punitive fees, which reduces barriers to in‑unit climate control.
- Medically vulnerable residents and seniors — Faster, more reliable access to cooling options that can prevent heat-related health emergencies when architectural bans are removed.
- Cooling equipment manufacturers and local installers — Expanded market access in common interest developments as members are freer to purchase and install a wider range of systems.
- Buyers and sellers of condo units — Greater certainty that recorded restrictions cannot be enforced to block retrofits, simplifying due diligence around climate-control upgrades.
Who Bears the Cost
- Associations and HOA boards — Lose a slice of architectural control and face potential liability and litigation costs if they continue to enforce bans; boards must update policies and train staff.
- Architectural committees and property managers — Administrative burden to adjust approval procedures and to distinguish safety/permit-based denials from prohibited bans.
- Neighboring owners and the community — May bear externalities (noise, visible equipment, changes to building façades) that associations can no longer broadly bar, potentially affecting aesthetics and shared amenity values.
- Permitting authorities and building departments — Possible uptick in permit applications and compliance inquiries as members install or modify cooling systems, increasing workload.
Key Issues
The Core Tension
The bill forces a trade‑off between individual health and comfort—allowing homeowners broad authority to install cooling—and the association’s interest in preserving communal aesthetics, structural safety, and uniformity; the statute solves the access problem for individuals but leaves unresolved how communities will manage the externalities and safety risks that follow.
The bill clears a legal bar to HOA prohibitions on in‑unit cooling but leaves several practical and doctrinal questions unresolved. It does not prescribe procedures for architectural review that satisfy safety and structural concerns, nor does it define the evidentiary threshold for a member to show that an installation would not violate law.
Associations and members will therefore clash over how to apply the statute in contexts where installations implicate shared systems, roof penetrations, or fire and electrical safety.
“Willful” violation triggers remedies, but the statute provides no definition or guidance on what constitutes willfulness. That elevates the importance of litigation to sort meaningful disputes and may produce a case law backlog where courts decide thresholds of culpability, appropriate damages, and whether equitable relief (injunctions) is available.
The permit exception gives local governments substantive sway: if a permit is lawfully denied, an association can deny on that ground, so local building codes and historic‑preservation rules will effectively limit member rights even where the statute otherwise forbids HOA bans.
Finally, the statute may produce cost shifting and unintended behavioral responses. Members may choose low‑cost or nonstandard equipment that meets the statutory “cooling benefit” test but creates noise or energy‑use consequences for neighbors.
Associations may instead try to regulate through collateral means—such as stricter maintenance rules, placement restrictions tied to safety, or new assessments to mitigate impacts—raising administrative and legal friction rather than eliminating it.
