City of Yes for Housing Opportunity is a citywide amendment to New York City's Zoning Resolution that the City Council adopted on December 5, 2024. It allows more housing in every part of the city through a set of changes: a 20 percent floor area bonus for affordable housing, small apartment buildings near transit in low-density areas, accessory dwelling units, lower parking mandates, and easier office conversions. It changed what existing zoning districts allow. It did not rezone specific sites.

What it is and how it works

The amendment (application N 240290 ZRY) rewrote large parts of the Zoning Resolution. The official record is on the Zoning Resolution site. The main components:

  • Universal Affordability Preference (UAP). In R6 through R10 districts, a building can have 20 percent more housing floor area if the added floor area is permanently affordable at a weighted average of 60 percent of area median income. Sites with 10,000 square feet or more of affordable floor area must provide at least 20 percent of it at 40 percent of area median income. See the housing agency's UAP fact sheet.
  • Transit-oriented development. In low-density areas, apartment buildings of three, four, or five stories (depending on the district) are allowed on "qualifying residential sites." Per the city's guide, a site must be near a subway or rail station, be 5,000 square feet or more, and sit on the short end of a block or face a street at least 75 feet wide.
  • Town center zoning. Apartment buildings of three to five stories are allowed along commercial corridors.
  • Accessory dwelling units. One ADU of up to 800 square feet is allowed on a lot with a one- or two-family home, with restrictions by location. See accessory dwelling units.
  • Parking. New housing has no parking mandate in the Inner Transit Zone, reduced mandates in the Outer Transit Zone, and largely unchanged mandates beyond the Greater Transit Zone. See parking minimums.
  • Conversions. Nonresidential buildings constructed before 1991 can convert to housing anywhere residential use is allowed, per the city's conversion guide.
  • Other changes. New high-density R11 and R12 districts that apply only where a later rezoning maps them, small and shared housing with common facilities, and infill on campuses and other large lots.

Who and where it applies

The amendment applies in all five boroughs, but each component has its own geography.

  • UAP applies in medium- and high-density districts, R6 through R10.
  • The transit-oriented rule applies in low-density areas near stations, and the town center rule along commercial corridors.
  • Parking relief depends on whether the lot is in the Inner Transit Zone, the Outer Transit Zone, or outside both.

Key dates

  • December 5, 2024: the City Council adopted the amendment with modifications (Mayor's Office announcement).
  • November 2025: a state court dismissed a lawsuit challenging the amendment, according to press reports.
  • December 2025: the city's one-year update reported more than 100 developments applying under UAP and 98 ADU filings.

Current status

As of October 2026, the amendment is part of the Zoning Resolution. The Mayor's Office said in December 2025 that a judge had dismissed a court challenge to it. According to press reports, that ruling came from a state Supreme Court justice on Staten Island in November 2025, and the plaintiffs said they intended to appeal. We could not confirm the status of any appeal, so check for later rulings before relying on a provision for a large project.

What this lets you build

Everything below is as of right. It needs building permits, but no rezoning, special permit, or public review.

  • On a lot in an R6 through R10 district: a building with 20 percent more residential floor area than the base rules allow, if the added floor area is permanently affordable housing under UAP.
  • On a 5,000 square foot or larger lot near a station in a low-density area: a three to five story apartment building, if the lot is on the short end of a block or on a wide street.
  • On a lot with a one- or two-family home: one ADU, as a backyard cottage, an attached unit, or a conversion of a garage, attic, or basement.
  • In a pre-1991 office or other nonresidential building where housing is allowed: conversion to apartments, supportive housing, dorms, or shared housing.
  • In the Inner Transit Zone: new housing with no required parking.

Limits and carve-outs

  • ADUs. Basement and detached ADUs are not allowed in the coastal flood zone or the 10-year high-risk flood zone. Detached ADUs are not allowed in R1-2A, R2A, and R3A districts outside the Greater Transit Zone, or as new structures in historic districts. The owner must live on the lot when the ADU is first occupied. Source: the housing agency's ADU FAQ.
  • UAP conditions. Affordable units must be spread through at least 65 percent of the building's stories and meet bedroom mix and unit size rules.
  • Parking. Removing existing parking takes a discretionary action.
  • Other law. The Building Code and the state Multiple Dwelling Law still apply.

How to check a specific parcel

  1. Look up the lot on ZoLa, the Department of City Planning's zoning map, and note the district, any special district, and whether it is in the Inner or Outer Transit Zone.
  2. For a transit-oriented site, confirm lot area, block position or street width, and that the lot is in the mapped eligibility area.
  3. For an ADU, check the flood maps and historic district status.

In Plotzy, filter parcels by zoning designation and lot size, for example lots of 5,000 square feet or more in a given district, then ask Zoning AI "What floor area ratio and height apply to this lot?" for an answer with the code section cited.
