309 West 85th Street, Manhattan

A 10-unit Upper West Side walk-up where curb enforcement and off-hours work shape the surrounding block.

A 10-unit Upper West Side walk-up that has remained in the same family line for over fifty years, passing from Jack Silverman in 1975 to Isadora Hecht today. While filings against the building itself are thin, street-level enforcement around the block tells a very active story. Three things to know:

Hydrant blockages and off-hours construction lead the surrounding street activity. Within three blocks, emergency services logged 287 illegal parking calls over the last year, led by 131 blocked hydrant reports and 62 sign violations. That sits alongside 143 general noise calls, where 70 complaints specifically cite off-hours construction work. The building itself stays out of these filings, but double-parking and curb friction are constant right outside.

Fifty years of continuous family custody across two generations. Deed transfers record Jack Silverman taking title in 1975, transferring to Isadora Silverman in 1976, and moving into 309 W. 85th St., LLC under Isadora Hecht in 2012. Multi-decade family control often keeps management stable, though operational systems can lean informal.

Direct calls are low, but primary code records are unverified. Building-scoped housing code violation data is unverified due to incomplete city data feeds, though direct tenant calls show only a single residential noise report from October 2024. An in-person inspection of common areas and plumbing is essential while city data feeds remain incomplete.

Quieter signals on this building and the blocks around it:

• Single building-level residential noise call recorded over the past two years, closed in October 2024
• 59 unsanitary condition reports logged within three blocks over the past year
• 17 rodent reports filed across the surrounding three-block radius in the last 12 months
