Plate 36 of 102BronxBronx Community Board 4

Grand Concourse NYPL

This site can hold about 75–96 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 108. The City's LIFT tracker lists 114 homes. That is more than the 96 homes the dwelling unit limit (ZR 23-52) allows under current zoning on the lot shown here; it is also more than the high estimate for qualifying senior housing, which the limit does not cover.

HPD's November 2025 announcement gives about 113 affordable homes, under a plan that needs a rezoning; none of the City documents checked gives the tracker's 114.

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.

  • Open public library on the lot, to be rebuilt

    The lot holds the Grand Concourse branch of The New York Public Library, built in 1959. HPD says the branch stays open until construction begins. The plan replaces it with a new 17,500 sq ft library on the lower floors, which uses part of the building's floor area.

  • Plan still needs a rezoning (not yet approved)

    When HPD chose the developer in November 2025, it said the project still needed public approvals, including a rezoning and the transfer of the City-owned lot. In September 2024, before the City Council adopted City of Yes on December 5, 2024, HPD estimated 50-60 homes under the zoning then in place and 90-100 under a proposed rezoning with City of Yes.

  • 1959 library building would be demolished

    HPD's November 2025 announcement says the plan for 155 E. 173rd Street will replace the existing Grand Concourse Library building with a new library that has about 113 affordable homes above it.

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 96 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.

  • Caution

    The lot has a building on it

    The lot has a building on record with 12,496 sq ft of gross building area, completed around 1957 (MapPLUTO; gross area includes space zoning does not count). HPD's RFP page and its September 2024 presentation say the library building was built in 1959. Zoning counts floor area already on a lot toward its maximum, so the figures above are the most the land could hold in total, not what could be added while that building stands.

Nearest subway station: 174-175 Sts (B D), 690 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.

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 its lot; 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 lot area (8,864 sq ft), the zoning portions, the floor area (standard 54,867; with qualifying affordable or senior housing 65,659; community facility 57,616 sq ft), the homes (low 76, base 94, high 96), and the flags and what limits the site first.
