New York HOA Fence & Exterior

Quick reference

Section 1: Overview — How fence and exterior rules work in New York

In New York, before you ask whether an association can regulate a fence, a paint color, siding, roofing, or landscaping, you have to ask a prior question: which ownership form does the community use? The answer decides which law applies, because each of the three common forms answers to different law.¹ Condominiums operate under the New York Condominium Act (Real Property Law Article 9-B). Cooperatives operate under corporate law — the Business Corporation Law and the Cooperative Corporations Law — plus a proprietary lease. Planned-community homeowners associations run on recorded covenants, the Not-for-Profit Corporation Law, and common law, with no comprehensive planned-community statute behind them.¹ In every form, the exterior standards come first and foremost from the governing documents.

The override picture is short and specific. New York protects a condominium unit owner's display of a United States flag under RPL § 339-j,² it limits planned-community restrictions on rooftop solar under RPL § 342,³ and it limits condominium restrictions on electric-vehicle charging under RPL § 339-ll.⁴ For cooperatives and planned communities, the federal Freedom to Display the American Flag Act of 2005 supplies the flag baseline.⁵ No New York statute sets an architectural-review response deadline or a deemed-approval rule, so the governing documents set the application timelines, and courts review condominium and cooperative board decisions under the deferential business-judgment rule.⁶ Separately, the Attorney General's Real Estate Finance Bureau regulates offering plans at the point of creation and sale under the Martin Act; it does not police ongoing exterior rules.⁷ Covenant-enforcement and injunction matters start in the Supreme Court, which is the trial court, move to the Appellate Division on appeal, and can reach the New York Court of Appeals, the highest court. The sections below lay out the framework, the compliance mechanics, and the recent activity.

Section 2: The legal framework for exterior and fence control

2A. Where exterior and fence authority comes from

The recorded governing documents are the primary source of architectural and exterior authority in a New York community, and the statutory backdrop turns on the ownership form.¹

For condominiums, the New York Condominium Act — RPL Article 9-B, RPL § 339-d and following — governs.¹ The Act applies to property submitted to its provisions. It requires each unit owner to comply strictly with the by-laws and with the rules, regulations, resolutions, and decisions adopted under them (RPL § 339-j),² and it requires the by-laws to address how the property operates (RPL § 339-v).⁸ So in a condominium, the architectural and exterior restrictions live in the declaration, the by-laws, and the rules a board duly adopts.

For cooperatives, you own shares in a corporation and hold a proprietary lease, and the corporation organizes under the Business Corporation Law — some cooperatives fall under the Cooperative Corporations Law.¹ The proprietary lease and the house rules control whether a shareholder may alter the apartment or its exterior elements, and courts review a board's enforcement decisions under the business-judgment rule that Matter of Levandusky v. One Fifth Ave. Apartment Corp. established.⁶ Writing for the Court of Appeals on April 5, 1990, Judge Judith S. Kaye put the standard plainly: "So long as the board acts for the purposes of the cooperative, within the scope of its authority and in good faith, courts will not substitute their judgment for the board's" (75 N.Y.2d at 538).⁶ The Condominium Act does not govern cooperatives.

For planned communities, New York has no comprehensive statute.¹ These associations answer to their recorded covenants, conditions, and restrictions, to the Not-for-Profit Corporation Law when the association incorporates as a nonprofit (as most do), and to common law. The architectural authority comes from the declaration and any rules the declaration authorizes.

Set the governing-law question aside for a moment, and one more regulator appears. The Attorney General's Real Estate Finance Bureau regulates the offer and sale of cooperative interests in realty — cooperatives, condominiums, and homeowners associations — under the Martin Act (General Business Law Article 23-A, GBL § 352-e and following), with regulations at 13 NYCRR Parts 18, 20, 21, and 22.⁷ That regulation handles disclosure at creation and sale through an offering plan; it does not operate as a regulator of exterior rules. New York has not adopted the Uniform Common Interest Ownership Act.¹

Within each form, the order of precedence runs from any mandatory statutory provision — for condominiums, RPL Article 9-B, including the RPL § 339-j flag protection — to the governing documents (the declaration and by-laws, or the proprietary lease and house rules), and then to board-adopted rules.

2B. State-law limits on association exterior authority

New York limits association exterior authority on a short list of features, and the reach of each provision depends on the ownership form.

Flags. RPL § 339-j bars any action or proceeding for relief against a condominium unit owner for displaying a United States flag that measures no more than four feet by six feet.² That protection is condominium-specific. For cooperatives and planned communities, the baseline is the federal Freedom to Display the American Flag Act of 2005, which bars condominium, cooperative, and residential real estate management associations from restricting a member's display of the U.S. flag, subject to reasonable time, place, and manner rules.⁵

Solar. New York limits solar restrictions through the Solar Rights Act (RPL Article 9-C, § 342), which bars a homeowners association from adopting or enforcing rules that would effectively prohibit or unreasonably limit a solar power system.³ RPL § 342(1)(b) defines the protected system word for word as "a photovoltaic system, comprising of solar electric generating equipment, installed on a rooftop, with a rated capacity of not more than twenty-five kilowatts," and § 342(2) deems unreasonable any limitation that "increases the solar power system's installation or maintenance costs by an amount which is estimated to be greater than ten percent of the total cost of the initial installation."³ The statute reaches systems on property the homeowner owns. It expressly lets an association restrict solar on property the association owns or holds in common, which means the protection generally does not reach condominium or cooperative roofs that count as common elements or corporation-owned property.³ A denial must come in writing, with a detailed basis.

Political and noncommercial signs. No New York statute limits association restrictions on political or noncommercial signs. For condominiums and cooperatives, courts review board sign restrictions under the business-judgment rule;⁶ for planned communities, the declaration governs.

Landscaping appearance, water-conserving or native plants, and artificial turf. No enacted New York statute shields drought-tolerant landscaping, native plants, or artificial turf from association restrictions. The Low Impact Landscaping Rights Act (S7358, Senator Rachel May / A1890, Assemblymember Deborah Glick) passed both houses in 2025, but Governor Kathy Hochul vetoed it on October 16, 2025, so the governing documents continue to control landscaping appearance, subject to the business-judgment rule for condominiums and cooperatives.⁹

Electric-vehicle charging. RPL § 339-ll bars a condominium from adopting provisions that effectively prohibit or unreasonably restrict installation of an electric-vehicle charging station, allowing only reasonable restrictions that do not significantly raise cost or cut performance.⁴

Fences. New York's floor for fences is safety, not aesthetics. The residential swimming pool and spa barrier requirements come from the New York State Uniform Fire Prevention and Building Code, which requires a barrier at least four feet high around pools that can hold water more than 24 inches deep, and it lets local governments adopt stricter standards.¹⁰ No other New York statute dictates fence height, material, or placement for associations; the governing documents and local zoning set those choices.

Where New York has no statute on a commonly protected feature — signs, paint, siding, roofing, and general landscaping appearance — the governing documents control, and for condominiums and cooperatives the board's choices answer to the business-judgment rule.

2C. The architectural review process and procedural limits

No New York statute imposes an architectural-review response deadline or a deemed-approval rule.¹ The governing documents set the application timelines. For condominiums, RPL Article 9-B (compliance under RPL § 339-j) and the by-laws govern the review;² for cooperatives, the proprietary lease and house rules govern; for planned communities, the declaration governs.

The business-judgment rule controls how courts review condominium and cooperative board decisions on architecture and exteriors. Under Levandusky, a court defers to a board decision the board took in good faith, within the scope of its authority, and in furtherance of the community's purposes, and it will not substitute its own judgment.⁶ The Court of Appeals kept a check in place, though: the rule "permits review of improper decisions, as when the challenger demonstrates that the board's action ... deliberately singles out individuals for harmful treatment" (75 N.Y.2d at 540), so review stays available where a board acts outside its authority, in bad faith, or in a discriminatory way.⁶ For planned communities, courts generally require covenant enforcement to be reasonable and applied uniformly under common-law doctrine.

Architectural standards hold up when they appear in the recorded instruments or the association duly adopts them under authority those instruments grant; unrecorded or improperly adopted restrictions are vulnerable. Before an association imposes fines or orders removal, it is generally expected to give notice and an opportunity to be heard — a point we develop further in our New York fining-authority coverage.

Section 3: Compliance obligations and operational mechanics

A. Association, cooperative, and board obligations

Maintain the architectural standards and make them available. Condominium boards must keep the declaration, by-laws, and rules on file and available (RPL Article 9-B); this duty is STATUTORY for condominiums.¹ Cooperative and planned-community boards must maintain the proprietary lease and house rules, or the declaration and rules; that duty is CONTRACTUAL or CORPORATE and varies by community.

Review and respond within any documented timeline. Because no statute sets a deadline, boards must follow the response timeline in their own governing documents; this duty is CONTRACTUAL or CORPORATE and applies to all three forms.¹

Respect the flag protection. A condominium board may not maintain an action against a unit owner over a U.S. flag of no more than four feet by six feet (RPL § 339-j); this duty is STATUTORY and condominium-specific.² The federal flag act binds cooperatives and planned communities.⁵

Act in good faith and within authority. Condominium and cooperative boards should document that they made an architectural decision in good faith and within the governing documents, so the decision holds under the business-judgment rule; this is a CORPORATE standard drawn from case law.⁶

Provide notice and an opportunity to be heard before you enforce. This duty is CONTRACTUAL or CORPORATE and applies across the forms.

B. Owner and shareholder obligations and rights

Get approval before you start work. A condominium unit owner must apply and obtain approval before installing a fence or doing exterior work where the by-laws require it; a cooperative shareholder must obtain approval under the proprietary lease and any alteration agreement. This duty is CONTRACTUAL or CORPORATE, applying to condominiums and cooperatives respectively.²

Build to the approved plans and published standards. Owners and shareholders must build to the approved plans and the published rules or house rules; CONTRACTUAL or CORPORATE, all forms.

Know your position when a board oversteps. An owner or shareholder can challenge a decision the board made outside its authority, in bad faith, or in a discriminatory way — those are the limits of the business-judgment rule; this is a CORPORATE standard for condominiums and cooperatives.⁶

Flag right. A condominium unit owner holds the RPL § 339-j right to display a U.S. flag within the stated size; STATUTORY, condominium-specific.²

C. Enforcement, remedies, and defenses

Remedies. RPL § 339-j lets a condominium board — or, in a proper case, an aggrieved unit owner — bring an action to recover sums due, to collect damages, or to obtain injunctive relief for violations of the by-laws and rules; this remedy is STATUTORY for condominiums.² Boards may also seek fines, forced removal or restoration, and recovery of enforcement costs or attorney fees where the governing documents authorize them; that remedy is CONTRACTUAL. Condominiums hold a lien for common charges under RPL § 339-z (STATUTORY), which we develop in our New York collections-and-liens coverage.¹¹ Cooperatives may pursue lease termination and ejectment remedies under the proprietary lease; CONTRACTUAL or CORPORATE.

Limits on enforcement. The business-judgment rule requires good faith and action within authority, so it does not protect an enforcement decision that is arbitrary, discriminatory, or outside the governing documents; this is a CORPORATE limit for condominiums and cooperatives.⁶

Owner and shareholder defenses. The common defenses are that the board acted outside its authority, in bad faith, or not in furtherance of the community's purposes; that the board enforced selectively or non-uniformly; or that the restriction exceeds what the governing documents allow.⁶

New York has no dedicated community-association-manager license and no ongoing operational HOA regulator. The Attorney General's Real Estate Finance Bureau regulates offering plans at creation and sale under the Martin Act, not the day-to-day exterior rules.⁷

Section 4: Recent legislative and judicial activity

A. Recent bills

B. Recent appellate rulings

C. Active legislative debates

The active proposals that touch exterior regulation include the SUNNY Act awaiting the Governor's action and the periodic reintroduction of low-impact-landscaping and solar-access measures aimed at condominium and cooperative roofs. None of them is enacted as of this writing.¹²

Section 5: National positioning and related coverage

New York is not a comprehensive common-interest-statute state for planned communities. Unlike California, Colorado, or Illinois, and unlike the Uniform Common Interest Ownership Act states, New York has no single planned-community statute; its planned-community HOAs run on recorded covenants and the Not-for-Profit Corporation Law.¹ At the same time, New York carries a developed condominium statute (RPL Article 9-B) and a large cooperative tradition that answers to corporate law and the business-judgment rule.⁶ The features that set New York apart are the three ownership forms, the deferential business-judgment standard from Levandusky, the Attorney General's offering-plan regulation under the Martin Act, and the inverted court naming in which the Supreme Court is the trial court and the Court of Appeals is the highest court.⁷ For a multi-state operator, the practical takeaway is simple: identify the ownership form before you analyze any exterior question, and expect deferential business-judgment review for condominium and cooperative board decisions.

HOA Weekly's New York Fence & Exterior coverage updates quarterly as the Legislature and the New York appellate courts act. Federal frameworks also reach New York communities regardless of the state framework, including the Freedom to Display the American Flag Act of 2005, the FCC over-the-air reception devices (OTARD) antenna rule, and the Fair Housing Act and ADA for reasonable accommodations that affect exterior features.
