What City of Yes for Housing Opportunity actually changed
New York's City Council adopted City of Yes for Housing Opportunity on December 5, 2024, one citywide zoning change expected to add about 82,000 homes over 15 years by allowing a little more housing in every neighborhood rather than concentrating it in a few. It legalizes backyard cottages up to 800 square feet, lets more empty offices convert to housing, adds a bonus of 20% more floor area at 60% of Area Median Income for affordable units, and rolls back mandatory parking across most of the city.
The numbers that matter
- What it is
- One citywide zoning text amendment, adopted by the City Council on December 5, 2024, applying a little more housing capacity to every neighborhood at once rather than rezoning block by block (NYC Department of City Planning, City of Yes for Housing Opportunity overview, read August 2026)
- The scale
- About 82,000 new homes over the next 15 years, by the Department of City Planning's own estimate for the final adopted version (NYC Department of City Planning, City of Yes for Housing Opportunity overview, read August 2026)
- The affordability bonus
- The Universal Affordability Preference lets buildings in medium- and high-density districts add at least 20% more housing if those added homes are affordable at 60% of Area Median Income (NYC Department of City Planning, City of Yes for Housing Opportunity overview, read August 2026)
- Accessory dwelling units
- Backyard cottages, garage conversions, and basement apartments up to 800 square feet, on a 1- or 2-family lot, where the homeowner lives on site (NYC Department of City Planning, Accessory Dwelling Units guide, read August 2026)
- Office conversions
- Eligibility for converting non-residential buildings to housing moved from buildings constructed before 1961 to buildings constructed before 1991, and expanded to anywhere residential use is allowed (NYC Department of City Planning, Convert Offices and Other Buildings to Housing guide, read August 2026)
- Parking mandates
- A 3-zone system: no parking mandate in the Inner Transit Zone, a reduced mandate in the Outer Transit Zone, and mandates largely unchanged beyond it; an R6 building that once needed parking for 50% of its units needs none in the Inner Transit Zone, 25% in the Outer Transit Zone (NYC Department of City Planning, Lift Costly Parking Mandates guide, read August 2026)
One rule change, all five boroughs at once
Most New York zoning changes apply to one site, one corridor, or one neighborhood, decided through a public review process specific to that location (read what ULURP is for how that usually works). City of Yes for Housing Opportunity took the opposite approach: a single zoning text amendment that changed the underlying rules everywhere at once, a little in every district rather than a lot in a few.
City of Yes for Housing Opportunity was adopted by the City Council on December 5, 2024.
City of Yes for Housing Opportunity is a zoning text amendment that addresses this crisis by making possible to build a little more housing in every neighborhood.
City Planning's own estimate of what the whole package adds up to, once every provision below is in effect:
The final version of City of Yes for Housing Opportunity is expected to enable the creation of 82,000 homes over the next 15 years.
The City Council adopted the text amendment, including modifications responsive to public feedback, in December 2024.
The version the Council passed trimmed some of what City Planning first proposed, after months of negotiation over neighborhood-specific concerns. The building heights the Department originally floated for small commercial-corridor and transit-area buildings, for one, came down before final passage.
The Universal Affordability Preference
The one piece of City of Yes aimed squarely at income-restricted housing rather than zoning capacity generally:
The Universal Affordability Preference allows buildings in medium and high-density districts to add at least 20% more housing, if the additional homes are income-restricted and affordable to households earning 60% of the Area Median Income (AMI).
This is a bonus a developer can choose to use, distinct from Mandatory Inclusionary Housing, which applies only in specific rezoned areas and is not optional there. For what an AMI percentage translates to in an actual rent, read <a href="/explained/what-affordable-housing-means-in-nyc/">what affordable housing means in New York</a>.
Backyard cottages and basement apartments
For the first time citywide, a homeowner on a 1- or 2-family lot can add a second, smaller home on the same property.
ADUs are 800 square feet or less and on the same lot as a 1- or 2-family home.
Homeowners must live at a property to build an ADU there.
An ADU is not a general-purpose small-lot development tool. It only exists attached to an owner who actually lives there.
Basement and detached ADUs are not allowed in an expanded flood area (2050 and 2080 flood plains)
Detached ADUs are not allowed in historic districts or some "contextual" zoning districts (R1-2A, R2A, R3A) outside of greater transit zone
A property inside a designated historic district answers to the Landmarks Preservation Commission on top of any zoning rule; read <a href="/explained/what-a-landmark-designation-actually-restricts/">what a landmark designation actually restricts</a>.
Turning empty offices into homes
Before City of Yes, an office or other non-residential building's age largely decided whether it could ever become housing.
many buildings constructed after 1961, or outside the city's largest office centers, could not become housing.
City of Yes for Housing Opportunity allows conversions for buildings constructed before 1991 and expands eligibility to anywhere residential uses are allowed.
Small apartment buildings above stores, and less required parking
The classic New York form of a few floors of apartments over ground-floor stores, common on low-density commercial strips built in the early and middle twentieth century, had been effectively illegal to build new for decades. City of Yes brought it back, matched to what already surrounds it:
These new buildings, known as "qualifying residential sites" in the Zoning Resolution, can have 2, 3 or 4 stories of homes above a commercial ground floor, depending on underlying zoning.
The change that touched the most property citywide, though, was to off-street parking. New buildings had to include parking spaces even where a landlord and every future tenant knew nobody would use them; City of Yes replaced that flat mandate with a geography-based one:
City of Yes has rolled back parking mandates via a 3-tier system: Inner Transit Zone: no parking mandates Outer Transit Zone: reduced parking mandates Beyond the Greater Transit Zone: mandates largely remain
before City of Yes, a building in an R6 zoning district was required to provide parking spaces for 50% of units, regardless of how close the building was to transit. Now, a building in an R6 district would not have to provide parking at all if it is in the Inner Transit Zone, would have to provide parking for 25% of units if it is in the Outer Transit Zone and 50% of units only if it is beyond the Greater Transit Zone.
No parking is required across the Manhattan Core and Long Island City Parking Areas and the Inner Transit Zone. This is the most populous mandate-free area in America with 2.6 million residents.
None of this removes a landlord's option to build parking anyway, and it does not touch parking that already exists.
Removing existing parking requires a discretionary action.
A parking lot does not become housing on its own just because the mandate that once required it is gone.
Two smaller pieces round out the package. Campuses, including churches and private residential co-ops with underused land, can add new height-limited buildings more easily, though not NYCHA's:
These changes do not apply to NYCHA campuses.
And a separate provision, unrelated to any single site, changes how apartment size itself is counted:
By lowering and standardizing the dwelling unit factor, City of Yes allows buildings with more studios and one-bedrooms.
The questions New Yorkers actually ask
What is City of Yes for Housing Opportunity?
A single citywide zoning text amendment, adopted by the New York City Council on December 5, 2024, intended to allow a little more housing in every neighborhood rather than concentrating new construction in a few. The Department of City Planning estimates it will enable about 82,000 new homes over the next 15 years.
What is the Universal Affordability Preference in City of Yes?
A bonus, not a mandate: it lets buildings in medium- and high-density districts add at least 20% more housing on top of what zoning otherwise allows, as long as those additional homes are income-restricted and affordable to households earning 60% of Area Median Income.
Can I build an accessory dwelling unit (ADU) in NYC now?
In many cases, yes. City of Yes allows ADUs, such as backyard cottages, garage conversions, and basement apartments, up to 800 square feet, on a lot with a 1- or 2-family home where the owner lives on site. Basement and detached ADUs are barred in expanded flood plain areas, and detached ADUs are barred in historic districts and some contextual low-density zoning districts outside the transit zone.
Did City of Yes eliminate parking minimums in NYC?
Not everywhere. It replaced a flat citywide mandate with a 3-zone system: no parking mandate in the Inner Transit Zone (which DCP calls the most populous mandate-free area in America, with 2.6 million residents), a reduced mandate in the Outer Transit Zone, and mandates that largely remain beyond that. An R6 building that once needed parking for 50% of its units, for example, now needs none in the Inner Transit Zone and 25% in the Outer Transit Zone.
What buildings can convert to housing under City of Yes?
Non-residential buildings, such as offices, constructed before 1991 (previously the cutoff was 1961), and the eligible area expanded to anywhere residential use is otherwise allowed, not just the city's largest office districts.
