New York, NY Zoning
Districts & Requirements
Every zoning district in New York with permitted uses, setbacks, height limits, and density requirements — in plain English. NYC uses the 1961 Zoning Resolution, heavily amended. The FAR system controls density — not height alone. In December 2024, the City Council passed City of Yes for Housing Opportunity (COYHO), the biggest zoning reform since 1961. Key changes: Universal Affordability Preference (UAP) gives a 20% density bonus for affordable units in R6-R10, new R11/R12 districts allow up to 18 FAR, ADUs legalized citywide, and office-to-residential conversions expanded to buildings built through 1990. Mandatory Inclusionary Housing (MIH) applies in rezoned areas — 20-30% permanently affordable units required.

Residential — Low Density
3 districts in New York
R1-2
Single-Family DetachedThe lowest-density residential district in the city. Detached single-family homes on large lots. Found in Staten Island, eastern Queens, and Riverdale. No path to density without a rezoning.
What you can build
- ✓Single-family detached home
- ✓Community facility (house of worship, school)
- ✓Home occupation
- ✗Two-family or multifamily
- ✗Commercial or retail
- ✗ADUs (not in R1 districts under COYHO)

- 5 ft each (total 13 ft min)
- Rear

What this means in practice
0.5 FAR on 5,700 SF = 2,850 SF max floor area, plus a 20% attic allowance under a pitched roof gets you to ~3,420 SF. That's a comfortable single-family home but there's no density play here. If you're evaluating R1-2 land near a rezoned corridor, the upside is a future map amendment — check the comprehensive plan.
R3-2
Low-Rise Detached/Semi-DetachedLow-density district allowing detached and semi-detached one- and two-family homes. Common in outer-borough neighborhoods transitioning from single-family to slightly higher density.
What you can build
- ✓Detached one- or two-family home
- ✓Semi-detached one- or two-family home
- ✓Community facility
- ✓ADU (per COYHO, with conditions)
- ✗Attached rowhouses
- ✗Multifamily apartments
- ✗Commercial or retail

- 5 ft each (total 13 ft min)
- Rear

What this means in practice
0.5 FAR on 3,800 SF = 1,900 SF of floor area plus attic allowance. Two-family homes are the play — owner-occupant with rental income. Under COYHO, ADUs are now legal in R3-2 (garage conversions, backyard cottages) in the Greater Transit Zone, which adds a third income stream. Check flood zone status carefully in coastal R3-2 areas — ground-floor ADUs are prohibited in FEMA flood zones.
R5
Low-Rise Attached/DetachedThe bridge between low-density and medium-density NYC. Rowhouses, small apartments, and detached homes coexist. Common throughout central Brooklyn, the Bronx, and Queens. The 1.25 FAR starts to make small multifamily pencil.
What you can build
- ✓Detached or semi-detached 1-2 family
- ✓Attached rowhouses
- ✓Small apartment buildings
- ✓Community facility
- ✓ADU (per COYHO)
- ✗Large apartment buildings
- ✗Commercial (without C overlay)
- ✗Manufacturing

- Front
- 10 ft (or 18 ft if providing parking)
- Side
- 0 ft (attached) or 5 ft (detached)
- Rear

What this means in practice
1.25 FAR on a 2,500 SF lot = 3,125 SF of floor area. On a standard 25x100 Brooklyn lot: 55% coverage = 1,375 SF footprint, three stories = 4,125 SF gross — but FAR caps you at 3,125 SF. The 30-ft rear yard is the real constraint on narrow lots. If you have a through-lot, the rear yard is measured from each street, which can free up buildable area. Under COYHO, ADUs add up to 800 SF that doesn't count against FAR in the Greater Transit Zone.
Residential — Medium Density
2 districts in New York
R6
Medium-Density ResidentialThe backbone of New York City housing. R6 covers huge swaths of Brooklyn, the Bronx, and Queens. Two development paths: Height Factor (tower-on-base, no height cap but FAR limited) or Quality Housing (contextual, street wall with setback, higher FAR). Most new development uses Quality Housing rules.
What you can build
- ✓Apartment buildings (elevator)
- ✓Two-family and rowhouses
- ✓Community facilities (4.8 FAR)
- ✓Mixed-use with C1/C2 overlay
- ✗Commercial without C overlay
- ✗Manufacturing
- ✗Hotels (without special permit)
Key numbers
- Height
- 55-75 ft depending on program
- Lot min
- None (but practical minimum ~2,500 SF)
- Width
- 18 ft
- Coverage
- 80% (interior) / 100% (corner)
- Front
- Streetwall to max base height, then 15 ft setback
- Side
- 0 ft (attached) or 8 ft (detached)
- Rear
- 30 ft
What this means in practice
R6 Quality Housing: 2.43 FAR on a 10,000 SF lot = 24,300 SF. At $250/SF hard cost, that's a $6M build plus land. With UAP (COYHO), you get 20% more floor area — 2.92 FAR — if the extra space is permanently affordable at 60% AMI average. That bumps you to 29,200 SF. Run the pro forma both ways. Community facility FAR of 4.8 is the sleeper play — schools, medical offices, and houses of worship get nearly double the residential FAR.
R6B
Contextual Low-RiseContextual district designed to preserve brownstone neighborhoods. Mandatory Quality Housing with strict street wall and height limits. Found in brownstone Brooklyn, Harlem, and historic neighborhoods throughout the city.
What you can build
- ✓Apartment buildings (walk-up or elevator)
- ✓Rowhouses and brownstones
- ✓Community facilities (2.0 FAR)
- ✓Mixed-use with C overlay
- ✗Buildings above 50 ft
- ✗Tower-on-base configurations
- ✗Commercial without C overlay
Key numbers

- Coverage
- 80% (interior) / 100% (corner)
- Front
- Street wall 30-50 ft, then 15 ft setback
- Side
- 0 ft (attached) or 8 ft (detached)
- Rear
- 30 ft
What this means in practice
2.0 FAR on a standard 20x100 Brooklyn lot (2,000 SF) = 4,000 SF of floor area. That's a classic four-story brownstone with 1,000 SF per floor. The 50-ft height cap and street wall requirement produce the kind of building already there — which is the point. If you're renovating or rebuilding in an R6B, the zoning basically says 'build a brownstone.' The 30-ft rear yard eats 30% of a 100-ft deep lot, so design accordingly.
Residential — Medium-High Density
1 district in New York
R7-2
Medium-High DensityWhere serious apartment development happens. Height Factor allows towers with no height cap (FAR-limited). Quality Housing provides higher FAR with contextual height limits. R7-2 is mapped along major avenues and near transit throughout the city.
What you can build
- ✓High-rise apartment buildings
- ✓Towers on base
- ✓Community facilities (6.5 FAR)
- ✓Mixed-use with C overlay
- ✓Inclusionary housing for bonus FAR
- ✗Commercial without C overlay
- ✗Manufacturing
Key numbers

- Front
- 15 ft above base height (wide st) / 20 ft (narrow st)
- Side
- 0 ft (attached) or 8 ft (detached)
- Rear
- 30 ft
What this means in practice
3.44 FAR on a 10,000 SF lot = 34,400 SF — roughly 35-40 apartments. With Inclusionary Housing bonus: 4.6 FAR = 46,000 SF, or ~50 units. The tower option requires a 45-ft wide lot minimum and 40% max tower coverage. On a 100x100 lot, that's a 4,000 SF tower floor plate — efficient for studios and one-beds. Quality Housing (contextual) gives higher FAR but caps height. Most developers choose based on lot shape: wide lots favor towers, narrow lots favor Quality Housing.
Residential — High Density
2 districts in New York
R8
High-Density ResidentialHigh-density residential mapped in Manhattan's prime residential neighborhoods, parts of Downtown Brooklyn, and along waterfront rezonings. The 6.02 FAR produces substantial buildings — 10-20 stories is typical. Community facility FAR of 6.5 enables major institutional projects.
What you can build
- ✓High-rise apartment buildings
- ✓Towers (no height cap under Height Factor)
- ✓Community facilities (6.5 FAR)
- ✓Mixed-use with C overlay
- ✓Inclusionary housing developments
- ✗Commercial without C overlay
- ✗Manufacturing

- Side
- 0 ft (attached) or 8 ft (detached)
- Rear
- 30 ft
What this means in practice
6.02 FAR on a 10,000 SF lot = 60,200 SF — that's a 15-story building at 4,000 SF per floor. With Inclusionary Housing: 7.2 FAR = 72,000 SF. At $350-450/SF hard cost in Manhattan, you're looking at $21-27M in construction on a 10K lot before land. The tower regulations require 40% max lot coverage above the base, so on a 10K lot the tower floor plate maxes at 4,000 SF. Structured or below-grade parking is standard. The 30-ft rear yard is negotiable via a rear yard equivalent (distributed open space).
R10
Highest-Density ResidentialThe highest mapped residential density in the traditional zoning (pre-COYHO). Found in Midtown East, the Upper East Side, and select waterfront areas. Tower regulations dominate — these are skyscraper sites. COYHO created R11 (15 FAR) and R12 (18 FAR) but they must be mapped through future rezonings.
What you can build
- ✓Residential towers (30+ stories)
- ✓Community facilities (10.0 FAR)
- ✓Mixed-use with C overlay
- ✓Inclusionary/MIH developments
- ✗Commercial without C overlay
- ✗Manufacturing
- ✗Low-rise construction (economically impractical)

- Rear
- 30 ft (or rear yard equivalent)
What this means in practice
10.0 FAR on a 10,000 SF lot = 100,000 SF of residential. At $500+/SF hard cost in prime Manhattan, that's $50M+ construction before land. Tower coverage is capped at 40% of the lot, producing a 4,000 SF floor plate on 10K — tight for luxury layouts. Developers commonly assemble multiple lots or purchase air rights to maximize buildable area. A 20,000 SF assembled site at 10 FAR = 200,000 SF, roughly 150-200 units or 80-100 luxury condos. Air rights transfers from landmarks and houses of worship are common in R10 districts.
Commercial
4 districts in New York
C1/C2 Overlay
Local Commercial OverlayC1 and C2 overlays are mapped on residential districts to allow local retail and services. The commercial FAR is typically 1.0 or 2.0, layered on top of the residential FAR. C1 allows local retail (grocery, dry cleaner). C2 adds funeral homes, repair shops, and other community services. The residential bulk follows the underlying R district.
What you can build
- ✓Ground-floor retail and services
- ✓Residential above (per underlying R district)
- ✓Mixed-use buildings
- ✓Restaurants and cafes
- ✓Medical and professional offices
- ✗Large-format retail (Use Group 10+)
- ✗Entertainment venues

What this means in practice
The overlay is the key to mixed-use in residential neighborhoods. An R7-2 lot with a C2-4 overlay gets 3.44 residential FAR plus 2.0 commercial FAR — but total FAR doesn't stack, it's whichever program you choose or a blend. The commercial FAR typically covers only the ground floor. The real value: you can build retail without a variance or rezoning. On an avenue in Brooklyn with an R6/C2-4 overlay, ground-floor retail at $40-60/SF rent significantly improves your NOI versus all-residential.
C4-4D
Regional Commercial (Contextual)Major retail and mixed-use corridors — think Fordham Road, Jamaica Avenue, Kings Highway. The D suffix mandates contextual Quality Housing rules: street wall, base height, and setback. Residential and commercial uses are both permitted at comparable FARs, making flexible mixed-use the default.
What you can build
- ✓Department stores and large retail
- ✓Apartment buildings
- ✓Mixed-use (retail + residential)
- ✓Office buildings
- ✓Hotels
- ✓Community facilities (4.8 FAR)
- ✗Manufacturing
- ✗Heavy commercial (auto body, lumber yard)
- ✗Buildings exceeding contextual height limits

- 30 ft (residential) / 20 ft (commercial)
What this means in practice
C4-4D is a solid mixed-use play on major retail corridors. 3.44 residential FAR on a 10,000 SF lot = 34,400 SF. The contextual rules keep it at 8-10 stories with a street wall, which is what lenders and the community expect. Ground-floor retail on these corridors commands $50-80/SF depending on location. If you're comparing C4-4D to an R7-2/C2 overlay, the C4 gives you more commercial flexibility (large retail, entertainment) without the overlay limitations.
C6-4
Central Commercial (High Density)The premier commercial district. Mapped in Midtown, Lower Manhattan, Downtown Brooklyn, and Long Island City. 10.0 FAR for both commercial and residential creates maximum development flexibility. Tower regulations control form. This is where the biggest deals happen.
What you can build
- ✓Office towers
- ✓Residential towers
- ✓Mixed-use high-rises
- ✓Hotels
- ✓Large retail and entertainment
- ✓Community facilities (10.0 FAR)
- ✗Manufacturing (Use Group 16-18)

What this means in practice
10.0 FAR on a 15,000 SF Midtown lot = 150,000 SF. At $600+/SF office construction cost, you're north of $90M before land. The tower coverage cap (40%) means a 6,000 SF floor plate on 15K — efficient for Class A office. Air rights purchases and Inclusionary bonuses can push effective FAR higher. In a Mandatory Inclusionary Housing area, providing 25-30% affordable units unlocks additional residential FAR. Plaza bonuses in C6-4 can add up to 20% more commercial FAR if you provide a public plaza meeting the stringent Zoning Resolution standards.
C6-9
Central Commercial (Highest Density)Created as part of the Greater East Midtown rezoning and expanded under COYHO. 18.0 commercial FAR — the highest in the country. Designed for supertall office towers near Grand Central Terminal. Landmark transfer mechanisms allow purchasing unused development rights from Grand Central, St. Patrick's Cathedral, and other landmarks.
What you can build
- ✓Supertall office towers
- ✓Mixed-use high-rises
- ✓Hotels
- ✓Major retail
- ✓Transit infrastructure improvements (required for some bonuses)
- ✗Manufacturing
- ✗Residential-only buildings (commercial must be primary)

18.0 FAR on a 25,000 SF site = 450,000 SF. One Vanderbilt (1.7M SF on ~33K SF) achieved roughly 51 FAR through the East Midtown bonus and landmark air rights. The Landmark Transfer mechanism is the real play: purchase unused development rights from nearby landmarks at $300-500/SF of transferable FAR. Required public realm improvements (transit, pedestrian, streetscape) cost $50-100M but unlock massive floor area. This is a $1B+ development district — not for the faint of heart.
Manufacturing
5 districts in New York
M1-1
Light Manufacturing (Low Density)Light manufacturing and commercial district. Found throughout the outer boroughs along rail corridors, waterfronts, and industrial areas. Allows a wide range of commercial uses plus light manufacturing. Under COYHO, office buildings in M1 districts built before 1991 are now eligible for residential conversion.
What you can build
- ✓Light manufacturing and assembly
- ✓Warehousing and distribution
- ✓Office and commercial
- ✓Hotels (with special permit)
- ✓Self-storage
- ✓Residential conversion of pre-1991 office buildings (COYHO)

What this means in practice
1.0 FAR limits you to one story of full-lot-coverage or two stories at 50% coverage. The play in M1-1 is last-mile logistics and warehouse — demand is insatiable near population centers. Land trades at $100-300/SF in Brooklyn M1-1 districts. The COYHO office conversion provision is a game-changer: if there's a pre-1991 office building in an M1 zone, you can now convert to residential without a rezoning. Check for IBZ (Industrial Business Zone) restrictions — conversions may be prohibited in designated IBZs.
M1-5
Light Manufacturing (High Density)High-density light manufacturing mapped in SoHo, DUMBO, Gowanus, and the Garment District. The 5.0 FAR produces the classic NYC loft building. Many M1-5 areas have been rezoned or are rezoning targets for mixed-use. JLWQA (Joint Living-Work Quarters for Artists) is technically the only residential use, but de facto residential conversions are widespread.
What you can build
- ✓Light manufacturing and design
- ✓Office and creative workspace
- ✓Large retail and showrooms
- ✓Hotels
- ✓JLWQA (artist live/work)
- ✓Residential conversion of pre-1991 offices (COYHO)

5.0 FAR on a 10,000 SF SoHo lot = 50,000 SF. Commercial loft space in M1-5 districts commands $60-100/SF office rent and $80-150/SF retail. The Gowanus rezoning (2024) converted M1-5 to MX with MIH — that's the template for future M1-5 conversions. If you're buying M1-5 land near a planned rezoning, you're betting on the upzone. In SoHo/NoHo, the 2021 rezoning replaced M1-5 with MX-2/MX-13 equivalents, unlocking residential at 8-12 FAR with MIH. The pattern is clear: M1-5 in desirable neighborhoods eventually becomes mixed-use.
M1-6
Light Manufacturing (Highest Density)The densest manufacturing district in the city. Mapped in Midtown's Garment District, parts of Hudson Yards, and Long Island City. 10.0 FAR with a potential plaza bonus to 12.0. These are prime conversion and redevelopment sites.
What you can build
- ✓High-rise commercial and office
- ✓Light manufacturing at scale
- ✓Hotels
- ✓Large retail
- ✓Community facilities (10.0 FAR)
- ✓Residential conversion of pre-1991 offices (COYHO)

What this means in practice
10.0 FAR on a 20,000 SF Garment District lot = 200,000 SF. With a qualifying plaza: 12.0 FAR = 240,000 SF. At current Midtown office rents ($60-85/SF Class A), that's $12-20M annual gross revenue potential. The COYHO office conversion expansion is huge here — pre-1991 Garment District buildings (most of them) can now convert to residential. A 200,000 SF office-to-resi conversion at $200-300/SF yields 200-250 apartments. These are the most valuable conversion targets in the city.
M2-1
Medium ManufacturingMedium manufacturing district allowing noisier and heavier uses than M1. Found along industrial waterfronts, rail yards, and heavy commercial corridors. No performance standards for noise, vibration, or emissions (unlike M1). Use Group 18 (heaviest) still excluded.
What you can build
- ✓Medium manufacturing and processing
- ✓Warehousing and distribution
- ✓Waste transfer and recycling
- ✓Fuel storage
- ✓Heavy commercial

What this means in practice
2.0 FAR on a 40,000 SF industrial lot = 80,000 SF. M2 sites are valued for logistics — proximity to highways and bridges matters more than FAR. Land cost is significantly lower than M1 ($50-150/SF in Brooklyn/Bronx) but there's no residential conversion play. The long-term bet on M2 land is infrastructure-driven: when a neighborhood gets rezoned, M2 often becomes M1 or MX. Check the comprehensive plan and any pending ULURP applications.
M3-1
Heavy ManufacturingThe most permissive industrial district. All manufacturing uses allowed including Use Group 18 (heavy industrial). Found in Hunts Point, Newtown Creek, and outer-borough industrial cores. No performance standards — the buffer district approach assumes incompatibility with residential.
What you can build
- ✓All manufacturing uses including heavy industrial
- ✓Power generation
- ✓Waste processing
- ✓Chemical and fuel storage
- ✓Warehousing and distribution

What this means in practice
M3 is the end of the line for zoning density. 2.0 FAR on large industrial parcels produces massive single-story buildings — distribution centers, power plants, waste facilities. Land is the cheapest in the city ($30-80/SF) but there's zero residential upside and limited commercial upside. If you're evaluating M3, you're in the logistics, energy, or infrastructure business. The only speculative play is infrastructure-adjacent: sites near planned transit or rezoning areas where the M3 designation might eventually change, but that's a 10-20 year bet.
Development Bonus Program
NYC offers multiple density bonus programs that stack differently depending on location. The Universal Affordability Preference (UAP), effective 2025, provides 20% more residential floor area in R6-R10 districts if the bonus space is permanently affordable at a weighted average of 60% AMI. In Mandatory Inclusionary Housing (MIH) areas, 20-30% affordable units are required — not optional — but you get the higher FAR from the rezoning. In legacy Inclusionary Housing Designated Areas, a voluntary 33% FAR bonus is available for providing affordable units. Plaza bonuses in high-density commercial districts add up to 20% commercial FAR for qualifying public spaces. The programs don't all stack — UAP does not apply in MIH areas. Run each scenario separately in your pro forma: base zoning, UAP, MIH (if applicable), and any special district bonuses.
Overlay Districts
Mandatory Inclusionary Housing (MIH) Areas
Designated in recent rezonings (since 2016). Developments over 10 units or 12,500 SF must provide 20-30% permanently affordable units. Four options depending on the area: Option 1 (25% at 60% AMI), Option 2 (30% at 80% AMI), Option 3 (Deep Affordability — 20% at 40% AMI), or a Workforce Option (30% at 115% AMI). No opt-out, no payment-in-lieu for projects over 25 units. MIH is mapped in most recent rezonings including Gowanus, SoHo/NoHo, and Bushwick. Check the MIH Area map at ZoLa before underwriting any site in a recently rezoned area.
Universal Affordability Preference (UAP) — COYHO
Citywide in R6-R10 and equivalent commercial districts. 20% density bonus (additional floor area) if the extra space is permanently affordable at a weighted average of 60% AMI, with no income band exceeding 100% AMI. For projects over 10,000 SF of affordable space, at least 20% of the affordable area must serve households at 40% AMI. Must be on-site, no off-site alternative. HPD application required before building permit. This is the biggest new tool in the developer's kit — 20% more FAR by right.
Inclusionary Housing Designated Areas (Legacy)
Pre-MIH voluntary program mapped in parts of Manhattan, Williamsburg, Greenpoint, and West Chelsea. Provides FAR bonuses (typically 33% more residential floor area) in exchange for affordable units at 80% AMI. Being superseded by MIH in new rezonings, but legacy areas still active. In R10 Inclusionary areas, base residential FAR of 10.0 can reach 12.0 with the bonus. Off-site affordable housing is permitted in designated areas.
Special Permit Areas and Special Districts
Over 60 Special Purpose Districts citywide, each with unique rules that override standard zoning. Key ones: Special Midtown District (bonus FAR for public space), Special Hudson Yards District (platform over rail yards, 30+ FAR achievable), Special Clinton District (anti-harassment protections), Special Coney Island District (amusement preservation). Always check if your site falls in a special district — the rules can dramatically change development potential in both directions.
Historic Districts (Landmarks Preservation Commission)
NYC has 150+ designated historic districts across all five boroughs. Any exterior alteration visible from a public way requires LPC approval (Certificate of Appropriateness). Demolition is extremely difficult to obtain. New construction must be compatible with the district's character. LPC review adds 3-6 months to your timeline. The tradeoff: unused development rights from landmarks can be transferred to adjacent lots, and historic tax credits (Federal 20% + State 20%) can significantly improve project economics on adaptive reuse.
FEMA Flood Zones
Significant portions of waterfront NYC (Rockaways, Red Hook, Lower Manhattan, South Brooklyn, Staten Island) are in FEMA flood zones. AE zones require flood-resistant construction with first habitable floor above base flood elevation (BFE). VE zones (coastal high hazard) prohibit basements entirely. Flood insurance is mandatory in AE/VE zones — budget $15,000-50,000/year for a multifamily building. Post-Sandy zoning amendments allow buildings to exceed height limits to elevate above BFE. Check the latest FEMA FIRM maps — they're being updated citywide.
Industrial Business Zones (IBZ)
16 designated IBZs across the city where the administration has committed to preserving industrial use. Residential rezonings are generally not supported in IBZs, and the COYHO office-to-residential conversion provision does not apply within them. Key IBZs: Hunts Point, North Brooklyn (East Williamsburg), Southwest Brooklyn, Jamaica. If your M-district site is in an IBZ, do not underwrite a residential conversion scenario — it won't happen.

What changed with City of Yes for Housing Opportunity?
Passed December 2024, effective 2025. The headline changes: Universal Affordability Preference (UAP) gives 20% bonus FAR for affordable housing in R6-R10 districts. ADUs legalized citywide (garage conversions, backyard cottages) with exceptions in flood zones. Office-to-residential conversions expanded to buildings through 1990 (previously 1977). New R11 (15 FAR) and R12 (18 FAR) districts created but must be mapped in future rezonings. Town center rezonings allow mixed-use in low-density areas near transit.
How does FAR work in NYC?
Floor Area Ratio is the total buildable floor area divided by the lot area. A 10,000 SF lot at 6.0 FAR = 60,000 SF of building. FAR is the primary density control — height limits, setbacks, and lot coverage are secondary shaping tools. Some floor area is exempt from FAR: mechanical space (typically 5-7% of the building), below-grade floor area, and certain affordable housing bonus areas. The practical buildable area is usually 85-90% of the theoretical FAR maximum after deducting for setbacks, rear yard, and tower coverage requirements.
What is Mandatory Inclusionary Housing (MIH)?
MIH requires permanently affordable housing in areas rezoned for more density since 2016. If your site is in an MIH area, any development over 10 units or 12,500 SF must provide 20-30% affordable units — no payment-in-lieu for projects over 25 units. The affordable units must be permanent (not time-limited), on-site (with limited exceptions), and distributed throughout the building. MIH applies to Gowanus, SoHo/NoHo, Inwood, East New York, Jerome Avenue, and other recent rezonings. Check HPD's MIH fact sheet for current income band options.
Can I convert my office building to residential?
Under COYHO (effective 2025), buildings constructed through 1990 in any district where residential is permitted — plus M1 districts — are now eligible for office-to-residential conversion. Previously the cutoff was 1977. Key exceptions: buildings in Industrial Business Zones (IBZs) are excluded. The conversion must comply with residential quality standards (light, air, room dimensions) and may trigger MIH or UAP affordable housing requirements depending on the district. This is a massive expansion — thousands of underperforming office buildings are now conversion candidates.
What's the difference between Height Factor and Quality Housing?
In R6-R10 districts, you choose one of two development programs. Height Factor has no height cap but lower FAR — buildings can be tall and slender (towers). Quality Housing has higher FAR but caps height and requires a street wall — buildings fill the lot and match the neighborhood context. In R6: Height Factor maxes at 2.43 FAR, Quality Housing at 2.43 FAR with better height. In R7-2: Height Factor gives 3.44 FAR, Quality Housing gives the same FAR but with contextual height limits. The choice depends on lot size and shape — towers need wider lots (45-60 ft minimum).
How do air rights work?
Every NYC lot has a maximum FAR. Unused FAR (the difference between what's built and what's allowed) can sometimes be transferred to an adjacent lot or, in special districts, to lots across the street or further. Landmark buildings with low built FAR are the biggest source — Grand Central Terminal's unused air rights supported One Vanderbilt. Transfers require a zoning lot merger (adjacent lots), a special permit, or a special district transfer mechanism. Air rights trade at $200-500+/SF in Manhattan depending on location and the receiving site's ability to use them.
