Zoning in Park Slope, Brooklyn
What is Park Slope zoned?
Park Slope is mostly R6B: 4,379 of its 6,731 tax lots (65%) are in R6B, with R7B (14%) and R6A (14%) next, based on PLUTO 26v2 lots inside the 2020 Park Slope NTA. R6B allows a residential FAR of 2.00 and a maximum height of 55 feet for standard buildings (ZR 23-22, ZR 23-432). Check any Park Slope address free on Zohgo.
Park Slope is one of the most uniformly contextual neighborhoods in the city: four "A" and "B" residence districts cover 95% of its tax lots.
Of Park Slope's 6,731 tax lots, 6,466 (96%) have a residence district as their main zoning district. Only 244 lots sit in commercial districts (mostly C4-4D and C4-3A) and 2 in M1-1. R6B, R7B, R6A and R7A together cover 6,406 lots (95.2%). These are contextual districts: they set a minimum and maximum base height and a firm building height cap, so new buildings line up with the existing rowhouse and apartment street walls instead of rising as towers.

Source: PLUTO 26v2, field zonedist1, lots inside the 2020 NTA boundary. "Standard" FAR and height are the ZR 23-21 / 23-22 and 23-42x limits for standard residences; affordable, senior and qualifying sites can go higher. Other districts: C6-2, R7-3, M1-1, PARK, C4-4A.
What the main districts allow
- R6B (65% of lots). Standard residential FAR 2.00, or 2.40 for qualifying affordable or senior housing (ZR 23-22). Street wall base between 30 and 45 feet, maximum building height 55 feet; for qualifying affordable or senior housing the base can reach 45 feet and the building 65 feet (ZR 23-432).
- R7B (14%). FAR 3.00, or 3.90 for qualifying affordable or senior housing. Base 40 to 65 feet, maximum height 75 feet (95 feet for qualifying affordable or senior housing).
- R6A (14%). Same FAR as R7B: 3.00, or 3.90 (ZR 23-22). Base 40 to 65 feet, maximum height 75 feet, or 95 feet for qualifying affordable or senior housing (ZR 23-432).
- R7A (2%). FAR 4.00, or 5.01 for qualifying affordable or senior housing. Base 40 to 75 feet, maximum height 85 feet (115 feet for qualifying affordable or senior housing).
- R8X (47 lots). FAR 6.02, or 7.20. Base 60 to 95 feet, maximum height 155 feet (175 feet for qualifying affordable or senior housing).
- C4-4D and C4-3A (240 lots). Commercial districts with their own residential equivalents; see our C4 zoning guide for their FAR.
A practical point for owners: R6B and R7B lots look alike on the street, but an R7B lot carries 50% more standard floor area (3.00 vs 2.00 FAR) and 20 more feet of height. Checking which side of a district line a lot falls on is the first step in any Park Slope feasibility study.

| Step | Calculation | Result |
|---|---|---|
| Lot | 20 ft x 100 ft (the median R6B lot in PLUTO is 1,878 sq ft with 19.75 ft of frontage) | 2,000 sq ft |
| Standard floor area | 2,000 x 2.00 (ZR 23-22) | 4,000 sq ft |
| With qualifying affordable housing | 2,000 x 2.40 (ZR 23-22) | 4,800 sq ft |
| Maximum dwelling units | 4,000 / 680 = 5.88; fractions of 0.75 or more round up (ZR 23-52) | 6 units |
| Height | Base 30 to 45 ft, building max 55 ft (ZR 23-432) | about 5 stories |
Floor area here is zoning floor area, not gross. Yards, lot coverage, landmarks review and the existing building can all reduce what is buildable; many Park Slope blocks are also in historic districts, which zoning tables do not show.
Commercial overlays
| Commercial overlay (overlay1) | Tax lots | Share of all lots |
|---|---|---|
| C1-4 | 583 | 8.7% |
| C2-4 | 255 | 3.8% |
| C1-3 | 47 | 0.7% |
| Any overlay | 885 | 13.1% |
885 lots (13%) carry a C1 or C2 commercial overlay, mostly C1-4. Because the overlays sit on R6B, R6A, R7A and R7B districts, commercial floor area on an overlay lot is capped at FAR 2.00 (ZR 33-121, column A), and community facility FAR follows the host district (for example 2.00 in R6B and 3.00 in R6A or R7B under the same table).
Special districts and inclusionary housing
- Special Gowanus Mixed Use District covers 142 lots in the Park Slope NTA (PLUTO "G"). The district aims to let light manufacturing and residential uses coexist and to encourage investment in a mixed use neighborhood (ZR 139-00).
- Special Downtown Brooklyn District touches 5 lots at the north edge.
- Mandatory Inclusionary Housing. 134 lots fall inside adopted MIH areas, mainly from the 2021 Gowanus Neighborhood Plan and the 2024 341 10th Street rezoning (DCP MIH dataset). There, affordable housing is required for new residential development.
- UAP elsewhere. UAP is the City of Yes program that lets a development or enlargement outside a Mandatory Inclusionary Housing area exceed the standard FAR, but only by the amount of affordable housing it provides (ZR 27-111). In R6B that means up to 2.40 FAR instead of 2.00; in R6A and R7B up to 3.90 instead of 3.00.
How we defined Park Slope and counted lots
- Boundary: the official 2020 Neighborhood Tabulation Area Park Slope (BK0602), published by NYC City Planning on NYC Open Data. Real-estate listings often draw Park Slope differently, so treat the edges as approximate.
- Lots: every tax lot in PLUTO version 26v2 (pulled October 26, 2026) whose latitude and longitude fall inside that boundary, 6,731 lots in total. 1 more lot in the same census tracts had no coordinates in PLUTO and is not counted. A cross-check using PLUTO's 2020 census tract field gave almost the same count.
- District: PLUTO's "zonedist1", which is the district covering the largest part of each lot. 253 lots are split by a district, overlay or special district boundary (PLUTO "splitzone"); each is counted once, under its main district. Special districts only appear in PLUTO when they cover at least 10% of a lot (PLUTO Data Dictionary).
- Lot counts measure how many parcels are in a district, not land area. A large lot and a small one each count as one.

R6B. In PLUTO 26v2, 4,379 of the 6,731 tax lots inside the 2020 Park Slope NTA (65%) have R6B as their main district. R7B (966 lots) and R6A (921 lots) are next.
How tall can I build in R6B in Park Slope?
For standard buildings, the street wall base must be 30 to 45 feet and the building can reach 55 feet. Qualifying affordable or senior housing can rise to 65 feet with a base up to 45 feet (ZR 23-432).
What FAR does R7B allow?
R7B allows a residential FAR of 3.00 for standard residences and 3.90 for qualifying affordable or senior housing (ZR 23-22). The maximum building height is 75 feet, or 95 feet for qualifying affordable or senior housing (ZR 23-432).
How many apartments fit on a 2,000 sq ft R6B lot?
At FAR 2.00 the lot has 4,000 sq ft of residential floor area. Divided by the dwelling unit factor of 680 that is 5.88, which rounds up to 6 units because the fraction is at least 0.75 (ZR 23-52). Yards, coverage and building code rules may reduce this.
