203 Underhill Avenue, Brooklyn

An Underhill Avenue walk-up with long-term management but a backlog of physical violations.

Managed by Alma Realty since 1998, this 72-unit Prospect Heights rental has long-standing management roots on the block. While ownership is permanent, day-to-day operations have left a physical backlog on the property's record. Three things to know:

The building currently carries twenty open violations. While none are marked as immediately hazardous, the property has twenty open violations on its record. This physical backlog overlaps with a history of 53 heat and hot-water complaints, including a building-wide outage logged on May 7, 2026, meaning basic systems require close inspection before you sign.

Indoor air quality has triggered some localized concern. A single air quality complaint was registered directly inside the building, but the surrounding three-block corridor has logged 6 indoor air quality calls over the last year, with the most recent on June 12, 2026. This type of pattern often flags riser scent-bleeding or ventilation issues traveling between apartments.

Overhead noise is a highly active neighborhood pattern. The three-block corridor around this address logged 1,479 helicopter-noise complaints in the last 12 months, with the most recent on July 16, 2026. This area sits directly under a highly active flight path, and while the vast majority are flagged as miscellaneous or police tracking rather than standard airport shuttles, the drone is persistent.

Quieter signals on this building and the blocks around it:

• 312 illegal parking complaints within three blocks last year, mostly blocking bike lanes and fire hydrants
• 90 pest complaints and 62 mold complaints registered in the surrounding block corridor over the last 12 months
• One electrical issue logged inside the building on June 22, 2026, which was subsequently closed
• Typical Prospect Heights street activity — the sidewalk is lively, but the overhead sky is where the real noise lives.
