40-21 78th Street, Queens

A two-family home where the surrounding block carries heavy curb competition, commercial sound, and air-quality filings.

A 1920 two-family house in Elmhurst where the building's own operational record has minimal recent coverage. The underwriting focus here belongs entirely to surrounding block friction, commercial sound, and localized air quality. Three things to know:

Parking and driveway access generate constant block-level friction. Curb space within three blocks sees intense friction: 322 illegal parking calls in the last year — mostly hydrant blocks (157 calls) and posted sign violations (106 calls) — paired with 284 blocked driveway reports. Drivers routinely fight over curb access on surrounding streets.

Commercial and party sound dominates the surrounding street faces. Storefront and venue activity creates a dense sound signature: 297 commercial noise calls logged within three blocks over the last 12 months, with 288 specifically citing loud music and parties. Off-hours commercial sound regularly spills onto nearby street faces.

Air quality and chemical vapor calls signal potential vent bleed nearby. Indoor air quality calls total 7 complaints within three blocks over the past year. In a two-family structure near active commercial strips, air quality filings on surrounding parcels signal potential exhaust or chemical vapor bleed from nearby retail operations.

Quieter signals on this building and the blocks around it:

• Residential noise reached 271 calls within three blocks over the last 12 months.
• Water system issues generated 137 reports within three blocks in the past year.
• Street and sidewalk noise logged 73 calls within three blocks over the last year.
