Housing violations
12 violations are open against this address under the Housing Maintenance Code. 1 of them is the class the city calls immediately hazardous.
- 1Immediately hazardous
- 6Hazardous
- 5Non-hazardous
- 0Information order
Open means the Department of Housing Preservation and Development has not recorded it as corrected, which is not the same as nobody having fixed it. The city publishes the apartment each was written against; that is not carried here, because a count says a building has a problem and an apartment number says whose.
The apartments
12 condominium apartments are assessed on this block, and the typical one is 882 sq ft (82 m²). They run from 78 to 136 m².
The city values the typical one at $121,760. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
Owner of record
803 REALTY GROUP, LLC
As the assessment roll records it. Only owners that read as a company are shown here; where the roll names an individual, nothing is published.

What is recorded here
Multiple filings, one stable building identifier.
New York City's Building Identification Number helps connect filings that may use different application numbers or describe different scopes of work. The records below are grouped because they publish BIN 4083087. They should not be read as a single construction project unless the underlying filings say so.
The matched set includes 6 alteration filing. Its latest status categories are 2 recorded as completed, 4 approved. Each filing page preserves its own status, dates, scope and source identifier.
