A multi-turnover Crown Heights two-family house on a block with active outdoor noise and air-quality filings.
A two-family Crown Heights townhouse built in 1931 that has seen four deed transfers since 2021, most recently selling in August 2026 for $3.25M. The house itself generates almost no code filings, putting the focus on recent renovation quality and surrounding block conditions. Three things to know:
Four deed transfers since 2021 trace rapid ownership changes. The house sold to an LLC in 2021, resold in 2022 for $3.5M, transferred again in May 2024 for $3.1M, and changed hands most recently in August 2026 for $3.25M. Four deeds in five years points to repeated flipping and re-positioning, making mechanical inspection crucial.
Air quality and food venting calls cluster within three blocks. Within three blocks, neighbors logged 13 indoor air quality reports alongside 9 food establishment complaints over the last 12 months. While off-building, localized odor and exhaust bleed across lower floors can linger, making riser placement and window orientation key.
Residential party noise dominates the immediate three-block radius. In the three blocks around the building, residents filed 286 residential noise complaints in the last year, led by 190 loud music and party calls. Block activity stays high into off-hours, so indoor exposure depends on building elevation and window orientation.
