City of Yes for Housing Opportunity Survives an Article 78 Challenge: What It Means

New York City's City of Yes for Housing Opportunity, the largest rewrite of the city's zoning rules in decades, was challenged in court soon after it passed. In November 2025 a state judge dismissed the challenge. The case is also a useful guide to Article 78, the main way New Yorkers challenge government decisions.

What City of Yes changed

City of Yes for Housing Opportunity is a citywide amendment to the New York City Zoning Resolution approved by the City Council in December 2024. It was the third part of a broader "City of Yes" program that also included zoning changes for carbon neutrality and economic opportunity. City planners estimated that the housing amendment could enable roughly 80,000 additional homes over 15 years by allowing modest additional housing in many neighborhoods, for example through changes affecting accessory dwelling units, conversions, parking requirements and development near transit. The New York City Department of City Planning summarizes the changes on its official page linked below.

For property owners, those rules can affect what can be built on a lot or next door. Before buying, it is worth understanding how title and recorded restrictions work and how easements and rights of way can limit use.

The lawsuit and the ruling

On March 25, 2025, a coalition of civic associations, community groups and several City Council members filed an Article 78 petition in State Supreme Court in Richmond County (Staten Island), captioned Old Town Civic Association et al. v. City of New York, Index No. 85065/2025. They argued that the city failed to comply with the State Environmental Quality Review Act (SEQRA) and City Environmental Quality Review (CEQR), and that splitting City of Yes into three separate reviews avoided analyzing the cumulative impact. The city responded that annulling the zoning changes months after they took effect would disrupt thousands of pending construction applications.

On November 12, 2025, Justice Lizette Colon dismissed the petition, concluding that the city's land-use approval process had worked as intended and produced an extensive record, and that the zoning law would remain in effect as written. Counsel for the petitioners said they were exploring their options, so further appeals should be checked.

How Article 78 works

Article 78 of the New York Civil Practice Law and Rules is the procedure for challenging actions and failures to act by state and local government bodies and officers. Under CPLR 7803, the questions that may be raised include whether the body failed to perform a duty enjoined upon it by law (similar to traditional mandamus), whether it acted without or in excess of jurisdiction (similar to prohibition), and whether a determination was arbitrary and capricious, affected by an error of law, or not supported by substantial evidence. Proceedings generally must be commenced within four months after the determination becomes final.

Article 78 is used in many property-related disputes, such as challenges to zoning variances, building permits, landmarks decisions and rent-regulation determinations. This guide to New York Article 78 proceedings explains the remedies in more depth, and this four-state comparison of state-court writs of mandamus shows how New York's approach differs from New Jersey, Texas and Missouri. Tenants dealing with illegal units may also find our article on suing a landlord over an illegal apartment useful.

Common Article 78 scenarios for property owners

• A building department refuses to issue a permit, or revokes one, after the owner relied on it.
• A board of standards and appeals or zoning board grants or denies a variance.
• A landmarks determination restricts alterations to a building.
• A rent-regulation agency issues a determination about a tenant's rent or services.
• An agency simply fails to act on a complete application.

In most of these cases the court reviews the agency record rather than holding a new trial, which is why it matters to make objections and submit evidence during the administrative process. Petitioners who missed that step often find that the court will not consider new material.

Article 78 versus other lawsuits

Article 78 is designed for reviewing government action. Disputes between private parties, such as a boundary dispute between neighbors, use ordinary civil actions instead; our guide to boundary line disputes covers that situation. Some challenges also combine an Article 78 claim with a request for a declaratory judgment, for example when a party argues that a local law is invalid in addition to challenging how it was applied.

Frequently Asked Questions

Is City of Yes for Housing Opportunity in effect?

Yes. The court's November 12, 2025 dismissal left the zoning amendment in effect. Check whether an appeal was filed.

How long do I have to file an Article 78 proceeding?

Generally four months from when the determination becomes final and binding. Some matters have shorter periods, so consult a New York lawyer promptly.

Can Article 78 force an agency to act?

Yes, when the agency has a clear legal duty to act. That part of Article 78 works like the traditional writ of mandamus.
