Council District 12, building by building.
Every registered condominium and cooperative inside City Council District 12 — Co-op City, Williamsbridge, Olinville, Eastchester, Edenwald, Baychester, and Allerton in the northeast Bronx — pulled from the city's own tax-lot file by its council-district assignment, then joined live to the city's enforcement records. Every figure cites its source and retrieval date (2026-07-03).
THE UNIVERSE
39 buildings. One of them holds four-fifths of the homes.
13 condominiums and 26 cooperatives, holding 13,421 residential units. One record dominates: 2049 Bartow Avenue — Co-op City, the largest cooperative housing development in the United States — carries 10,914 homes on a single tax lot, 81.3% of the district's total. The other 38 buildings are a different world entirely: small co-ops and condos, most of them in the Williamsbridge–Olinville corridor.
| Neighborhood (city tabulation area) | Condos | Co-ops | Total | Homes |
|---|---|---|---|---|
| Williamsbridge-Olinville | 8 | 15 | 23 | 1,205 |
| Eastchester-Edenwald-Baychester | 3 | 5 | 8 | 791 |
| Allerton | 1 | 4 | 5 | 303 |
| Co-op City | 1 | 2 | 3 | 11,122 |
| District total | 13 | 26 | 39 | 13,421 |

IMMEDIATELY-HAZARDOUS VIOLATIONS
28 buildings carry open Class C violations. 1,136 of them.
Class C is HPD's most severe routine violation class: no heat, no hot water, severe leaks, structural hazards. As of 2026-07-03, 28 of the district's 39 buildings (71.8%) carry at least one open Class C violation, and 1,136 Class C violations stand open district-wide. "Open" is HPD's own status flag; some open violations are longstanding — the count is a stock, not a flow.

Scale matters here, so state it plainly: Co-op City holds 81.3% of the district's homes and accounts for 28.2% of its open Class C violations (320 of 1,136). The remaining 816 stand across 27 far smaller buildings — six of the top ten sit in the Williamsbridge–Olinville corridor alone.

FACADES · VACATE ORDERS · WHO MANAGES
The rest of the enforcement record.
Facade inspections (FISP / Local Law 11)
- 4 buildings' most recent facade status is UNSAFE; 2 more are SWARMP (safe with a repair program).
- 5 buildings' latest facade record reads "No Report Filed."
- Of 8 single-building lots taller than six stories, 3 have no facade filing at all (cycles 6–10).
DOB facade-compliance filing records — public city data, retrieved 2026-07-03. The 2049 Bartow Avenue lot records 250 structures under one tax lot; the lot's primary building identifier shows SAFE (cycle 9), but per-structure status cannot be resolved from it, so Co-op City is excluded from the no-filing count rather than guessed at.
City-issued vacate orders
- 3 buildings have a vacate order on record — 3 orders, vacating a recorded 4 homes.
- All 3 orders carry no recorded rescind date.
HPD vacate-order records — public city data, retrieved 2026-07-03.
Registration & self-managed share
- 36 buildings hold an HPD property registration; 3 do not.
- 3 of the 36 registered buildings (8.3%) list no managing-agent organization — each lists an individual with no firm.
- New York licenses none of the people doing that work.

WHY DISTRICT PROFILES
A building-level baseline for any district.
The Real Deal reported on March 31, 2026, that Council members are forming a Co-op and Condo Caucus with two stated priorities: preserving co-ops and condos as affordable homeownership, and equitable implementation of Local Law 97. As of 2026-07-03, no such caucus appears on the Council's official caucus list, and no membership or leadership has been announced. Whatever form it takes, its work needs a data floor — so CondosCoopsNYC publishes district profiles: see Congressional District NY-13 and Council District 26. The same profile can be built for any of the other 50 Council districts.

METHOD & SOURCES
How the district list was built.
- Universe: the CCNYC master building list — 15,108 registered condominium and cooperative buildings citywide, built from the Department of City Planning's tax-lot file (PLUTO 25v4) — filtered on that file's own City Council district assignment. 39 records carry District 12.
- Exclusions, disclosed: 57 of the 15,108 master records citywide carry no council-district assignment and are excluded from every council-district profile; none of the 57 lies in a District 12 ZIP code. 1 in-district record carries no residential-unit count and enters the homes total as zero.
- Cross-checks: ten randomly sampled District 12 buildings — including the Co-op City lot — were tested by coordinates against the city's official council-district boundary file — ten of ten fall inside District 12. The condo/co-op split and building count were independently recomputed from the master file before publication.
- Enforcement joins (all public city data, retrieved 2026-07-03): HPD violation records, HPD vacate-order records, DOB facade-compliance filings, and HPD property-registration records with their contact rosters, each joined per building live — not taken from the static master file. Where the live record and the master file's cached counts disagree, the live retrieval governs.
- Limitations: HPD violation counts join at the tax-lot level, so Co-op City's 250 structures aggregate into a single record — per-tower detail is not resolvable here; facade joins use each lot's primary building identifier, which 4 of the 39 tax lots lack, and multi-building lots (3 over six stories, including Co-op City) are excluded from the no-filing count rather than guessed at; "open" violation counts are stocks, not annual flows; "no managing-agent organization" is a registration-record fact, not a claim about day-to-day operations.
Exact dataset references and reproduction steps live on the methodology page. Numbers on this page are frozen to the 2026-07-03 retrieval; they will drift as HPD and DOB records move.
