320 Concord (New York City Borough - Based Jail System)
This site can hold about 245–309 homes under the zoning maximum for qualifying affordable housing. The top of that range is set by the dwelling unit limit (ZR 23-52); qualifying senior housing is exempt from it and could hold up to about 347. The City's LIFT tracker lists 234 homes.
The tracker's 234 is close to the 2019 approval's figure of about 235 affordable homes.

What City documents say
Facts from City documents that bear on the figures below. Each is quoted in the sources, and each speaks as of its document's date.
Next to the planned Bronx borough-based jail
The housing site is the western strip of the block that holds the City's planned Bronx Detention Complex at 745 East 141st Street. The jail's final design went to the Public Design Commission in August 2026.
2019 approvals: rezoning, MIH and UDAAP for housing
As part of the 2019 borough-based jail approvals, the City rezoned the land between Concord Avenue and a line 100 feet southeast of it, from East 141st to East 142nd Street, from M1-3 to M1-4/R7X with a Special Mixed Use District (MX-18) (C 190336 ZMX), mapped Mandatory Inclusionary Housing (N 190337 ZRX), and approved the site for about 235 affordable homes (C 190338 HAX). The City Council adopted them on October 17, 2019.
Housing lot split from the jail parcel in 2025
Finance records show the former 183,400 sq ft lot was divided in 2025 into the jail parcel (Lot 1, 145,634 sq ft) and the 35,000 sq ft housing lot (Lot 2, 320 Concord Avenue).
What can legally go here
Floor area follows exactly from the Zoning Resolution. Homes are a range, because unit size and building efficiency are choices.
- Lot area
- 35,000 sq ft
- Zoning district
- M1-4/R7X
- Maximum residential floor area
- 175,000 sq ft35,000 sq ft × 5.00 FAR
- With qualifying affordable or senior housing
- 210,000 sq ft35,000 sq ft × 6.00 FAR
- Maximum community facility floor area
- 175,000 sq ft35,000 sq ft × 5.00 FAR
Homes, as a range
| Case | Homes | How |
|---|---|---|
| Low | 245 | 210,000 sq ft × 0.7 ÷ 599 sq ft |
| Base | 303 | 210,000 sq ft × 0.8 ÷ 553 sq ft |
| High | 309 | 210,000 sq ft × 0.85 ÷ 514 sq ft = 347, capped at 210,000 ÷ 680 (ZR 23-52) |
Floor area × efficiency ÷ average home size. Efficiency 0.7–0.85; average home 514–599 sq ft. Assumptions and their basis.
What binds first
Dwelling unit limit
The dwelling unit limit (ZR 23-52) holds the site to at most 309 homes, fewer than its floor area could hold at the smaller home sizes in the range. Floor area still limits the size of the building.

What gets in the way
Flags are flags, not verdicts. Each comes from a public layer, named in the sources.
- Note
In a Mandatory Inclusionary Housing area
MIH options 1 and 3 apply, so new housing here must include permanently affordable homes (ZR 27-131).
- Note
In the Special Mixed Use District - 18 (Mott Haven, The Bronx)
Follows the general Special Mixed Use District rules, which the figures above already apply; MX-18 has no floor area rules of its own.
Nearest subway station: E 143 St-St Mary's St (6), 910 ft in a straight line.
What this doesn't account for
Public data and the zoning text answer the questions above. These need information that is not public, or a decision that belongs to the City.
- Public land use review (ULURP). Selling or leasing City land, or approving a housing project on it, generally goes through ULURP (community board, borough president, City Planning Commission, City Council), and this estimate does not presume the outcome.
- Disposition of City property (Charter 384 / UDAAP). Transferring the land needs Mayoral approval under Charter Sec. 384 and, for HPD projects, usually Urban Development Action Area designation and project approval under NY General Municipal Law Article 16.
- Environmental review (CEQR/SEQRA). Any discretionary approval, disposition or City funding triggers CEQR/SEQRA review, which can require mitigation (e.g. for hazardous materials, noise or historic resources) or reshape the project.
- (E) designations. A lot with an (E) designation or environmental restrictive declaration for hazardous materials, air quality or noise cannot receive building permits until the Office of Environmental Remediation signs off.
- Subsurface and site conditions. Unknown soil, rock, groundwater and contamination can shrink or eliminate cellars and add foundation and cleanup costs, and HPD requires every project to investigate and, if needed, remediate contamination.
- Deed restrictions and reverter clauses. Land the City bought or sold may carry deed restrictions or reverter clauses limiting its use, which must be checked in title records (ACRIS) and DCAS's deed-restriction database.
- Parkland alienation. If a site is municipal parkland, it cannot be sold or used for housing without an act of the State Legislature signed by the Governor.
- Current occupants, uses and agency plans. Many City-owned lots are in active use or assigned to an agency, or have funded capital projects, and this estimate does not reflect relocation needs or agency plans (check COLP and the Capital Commitment Plan).
- Mapped streets, easements and utilities. Mapped-but-unbuilt ('paper') streets, sewer and water easements and utility lines can take land out of the buildable area, and no permit may be issued for a building in the bed of a mapped street.
- Street access. A lot with no frontage on a mapped street cannot get a building permit on its own and must be combined with a neighboring lot or have access mapped.
- Landmarks review. Sites that are individual landmarks or inside historic districts need Landmarks Preservation Commission approval, which can limit demolition, height and bulk.
- Flood-resistant construction. Sites in the 1% annual chance floodplain (or the 0.2% shaded X-Zone for critical facilities) must meet Building Code Appendix G, whose elevation and floodproofing rules can cost usable ground-floor and cellar space.
- Airport height limits. Near JFK, LaGuardia and Floyd Bennett Field, zoning flight-obstruction surfaces cap building height, and tall structures anywhere need FAA notice.
- State and federal funding conditions. Federal or State money brings its own requirements (e.g. HUD environmental review under 24 CFR Part 58, Davis-Bacon prevailing wages, Section 3 hiring) that can change cost, timing and program.
- Zoning capacity is a ceiling, not a plan. The figures show what zoning allows, and actual HPD projects often build less, for example to fit neighborhood context, a community facility or funding limits.
