A four-unit East New York pre-war where street-level storefront enforcement shapes the block.
This 1923 four-unit rental sits on a block dominated by street-level commercial enforcement calls. Building-level code violation data is unverified, so the immediate three-block area carries the operational read. Three things to know:
Unlicensed smoke shop calls dominate the immediate three-block radius. 175 unlicensed smoke shop calls were logged within three blocks over the last year, including 72 for unlicensed operations and 43 for sales to minors under 21. The pattern stayed active through September 19, 2026, marking a heavy retail enforcement corridor.
Commercial sign and hydrant enforcement drives heavy parking activity. 230 illegal parking calls were filed within three blocks over the last 12 months, with 163 specifically for posted sign violations and 27 for blocked hydrants. This reflects short-errand commercial curb turnover rather than abandoned vehicles.
Pest and mold calls concentrate on adjacent properties along the block. 148 unsanitary condition reports hit the surrounding three-block area in the last year, including 100 pest complaints and 37 mold calls. While logged across neighboring properties, moisture and pest issues frequently cross attached party walls.
