623 West 170th Street, Manhattan

Washington Heights walk-up with a long family history that's carrying a housing violation backlog and active street noise.

The building changed hands in December 2021 for $4,408,333, ending nearly fifty years of ownership under Ronad Holding Corp. Now managed by Longview Property Services, the property stands in tension: daily tenant maintenance needs get quickly resolved, but a stubborn backlog of outstanding building filings remains. Three things to know:

The building carries 31 open violations. Day-to-day maintenance requests for doors or plumbing get resolved and closed quickly, but a backlog of 31 open housing violations remains unresolved. These active items continue to linger on the property's record.

Ventilation and odor issues on the surrounding blocks. Active air complaints crop up in the neighborhood, with 6 indoor air quality calls and 12 food establishment complaints logged over the past year. Since kitchen odors from downstairs retail can drift up through structural columns, check unit seals. The food complaints were active through April 21, 2026, and inner air calls ran until June 6, 2026.

Loud music is a highly active feature on the block. The surrounding blocks logged 367 street noise complaints last year, and 355 of those specifically flagged loud music or parties. These issues ran hot right up to July 20, 2026, making localized street volume a persistent part of daily life here.

Quieter signals on this building and the blocks around it:

• 71 illegal parking complaints directly at this address, largely targeting a blocked hydrant out front
• 31 heat and hot water complaints, though records show each was closed out quickly
• 16 encampment calls in the surrounding blocks, with none logged since December 2025
• The block is chronically tight on curb space, but day-to-day maintenance inside stays active.
