Plate 47 of 102BrooklynBrooklyn Community Board 2

Third Avenue

This site can hold about 45–59 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 66. The City's LIFT tracker lists 68 homes. That is more than the 59 homes the dwelling unit limit (ZR 23-52) allows under current zoning on the lots shown here; it is also more than the high estimate for qualifying senior housing, which the limit does not cover.

HPD's April 2025 announcement gives about 68 senior 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.

  • Senior housing: about 68 affordable apartments

    HPD selected the Third Act Apartments team in April 2025 to build about 68 affordable senior apartments in a mixed-use building. HPD's 2024 request for proposals required the building to use its Senior Affordable Rental Apartments program.

  • L-shaped site of five City lots, now parking

    HPD's 2024 request for proposals defines the site as five lots (about 7,200 sq ft) with frontage on Third Avenue and Wyckoff Street. Four lots were a parking lot; a one-story building on the fifth lot was demolished (Department of Buildings sign-off July 9, 2024).

  • Same City block as the Nevins Street housing site

    This site and the Nevins Street site (Block 388, Lot 1) were offered together in HPD's 2024 Nevins and Third request for proposals, but they are separate lots and separate projects.

Floor area follows exactly from the Zoning Resolution. Homes are a range, because unit size and building efficiency are choices.

What binds first

Dwelling unit limit

The dwelling unit limit (ZR 23-52) holds the site to at most 59 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.

  • Hazard

    Stormwater flooding in an extreme storm (2080s)

    DEP's Stormwater Flood Map (extreme stormwater flood with 2080 sea level rise) shows nuisance flooding (4 in to 1 ft) on about 18% of the site (1,290 sq ft).

  • Note

    In a Mandatory Inclusionary Housing area

    MIH options 1 and 2 apply, so new housing here must include permanently affordable homes (ZR 27-131).

  • Note

    Stormwater flooding in a moderate storm (2050s) on a small share of the site

    Less than 1% of the site (about 61 sq ft) shows nuisance flooding (4 in to 1 ft) on DEP's Stormwater Flood Map (moderate stormwater flood with 2050 sea level rise). It is shown for reference and not counted as a flood constraint on the site.

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.

Notes
On September 25, 2026, the MapPLUTO records and zoning district map behind this page were compared with DCP's live MapPLUTO (26v2) and zoning district layers for all 5 of its lots; every compared field and district boundary matched. A separate calculation, written from the method page and run on the same downloaded City data on September 25, 2026, reproduced the 5 lots and their area (7,200 sq ft), the zoning portions, the floor area (standard 33,552; with qualifying affordable or senior housing 40,320; community facility 33,552 sq ft), the homes (low 47, base 58, high 59), and the flags and what limits the site first.
