NY-13, building by building.
Every registered condominium and cooperative inside New York's 13th Congressional District — Harlem, East Harlem, Washington Heights, Inwood, Marble Hill, and the west Bronx — placed inside the official Census district boundary by coordinates, then joined live to the city's own enforcement records. No ZIP-code approximation. Every figure cites its source and retrieval date (2026-07-02).
THE UNIVERSE
1,051 buildings. Two very different segments.
533 condominiums and 518 cooperatives, holding 59,611 residential units. The Manhattan side of the district is majority-condominium; the Bronx side is overwhelmingly cooperative, much of it small, older co-op stock. That difference carries through every enforcement number below.
| Segment | Condos | Co-ops | Total |
|---|---|---|---|
| Manhattan (Harlem, East Harlem, Washington Hts, Inwood, Marble Hill) | 512 | 386 | 898 |
| Bronx (west-Bronx portion of the district) | 21 | 132 | 153 |
| District total | 533 | 518 | 1,051 |

IMMEDIATELY-HAZARDOUS VIOLATIONS
606 buildings carry open Class C violations. 8,879 of them.
Class C is HPD's most severe routine violation class: no heat, no hot water, severe leaks, structural hazards. As of 2026-07-02, 606 of the district's 1,051 buildings (57.7%) carry at least one open Class C violation, and 8,879 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.

Two patterns, stated neutrally: all ten are cooperatives, and three of the ten stand within two blocks of one another on Davidson Avenue in University Heights — 624 open immediately-hazardous violations across three small co-ops totaling 162 units.

FACADES · VACATE ORDERS · WHO MANAGES
The rest of the enforcement record.
Facade inspections (FISP / Local Law 11)
- 51 buildings' most recent facade status is UNSAFE.
- 65 buildings' latest facade record reads "No Report Filed."
- Of 359 single-building lots taller than six stories, 77 have no facade filing of record at all (cycles 6–10).
DOB facade-compliance filing records — public city data, retrieved 2026-07-02.
City-issued vacate orders
- 74 buildings (7.0%) have a vacate order on record — 91 orders, vacating a recorded 284 homes.
- 24 orders across 21 buildings carry no recorded rescind date.
HPD vacate-order records — public city data, retrieved 2026-07-02.
Self-managed share
- 981 buildings hold an HPD property registration; 70 do not.
- 124 of the 981 registered buildings (12.6%) list no managing-agent organization: 109 list an individual with no firm, 15 list no agent at all.
- Roughly one registered building in eight runs with no management firm of record — and New York licenses none of the people doing that work.

THE ANCHOR BUILDING
Where 775 Riverside Drive ranks.
The John James Condominium (BBL 1021347504, 133 units, Washington Heights) is the subject of a Level 4 public-interest investigation. Against the district's other 1,050 buildings, all figures retrieved 2026-07-02:
| Metric | 775 Riverside | District rank (1 = most severe) |
|---|---|---|
| Vacate orders on record | 3 | Tied for 1st of 1,051 |
| Lifetime Class C violations | 172 | 49th of 1,051 (top 5%) |
| Open Class C violations | 17 | Tied 155th |
| Open violations, all classes | 46 | Tied 227th |
| Facade (FISP) status | UNSAFE | One of 51 currently UNSAFE |
| Managing-agent organization | None listed | One of 124 such registered buildings |
775 Riverside is not the district's single worst building on any one count. It is the only building in NY-13 that simultaneously sits at the district maximum for vacate orders, carries a current UNSAFE facade status, ranks in the top five percent for lifetime immediately-hazardous violations, and runs with no managing-agent organization of record. Every element of that configuration is lawful — which is the point of the case study.

METHOD & SOURCES
How the district list was built.
- Boundary: the U.S. Census Bureau's official congressional-district boundary file for the 119th Congress (2025 vintage, post-2022 lines). Downloaded 2026-07-02.
- Assignment: all 15,108 buildings in the CCNYC master list tested point-in-polygon on their PLUTO coordinates; 1,051 matched. 57 master records with no usable coordinates were excluded (none carries a district-core ZIP). No ZIP approximation was used.
- Cross-checks: 775 Riverside Drive falls inside the polygon; ZIP distribution reconciles against the district's core-ZIP estimate; ten randomly sampled buildings plus the anchor were confirmed as "Congressional District 13" by the U.S. Census Geocoder (11 of 11).
- Enforcement joins (all public city data, retrieved 2026-07-02): HPD violation records, HPD vacate-order records, DOB facade-compliance filings, and HPD property-registration records, each joined per building.
- Limitations: facade joins use each lot's primary PLUTO BIN, so multi-building lots (28 over six stories) are excluded from the no-filing count rather than guessed at; "open" violation counts are stocks; "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 2026-07-02 retrieval; they will drift as HPD and DOB records move.
