Regulated Sunset Park rental with a stable regulatory backdrop and tight street parking outside.
A 6-unit Sunset Park building with a long history of HUD financing and project-based affordability covenants. Three things to know:
Winter heat complaints pop up, but they resolve. Three building-wide heat and hot water complaints appear on file over the past two winters (November 2024, December 2025, and January 2026), all marked closed. It points to seasonal winter strain rather than systemic failure, but boiler performance is the main operational item to check.
Curb space is tight within three blocks. 135 illegal parking calls logged within three blocks over the last 12 months, driven by 44 blocked hydrants and 22 posted sign violations. It is short-errand curb pressure along the avenue rather than stored vehicles, but double-parking and delivery idling are constant on the blockface.
Street noise and air quality calls show up on the surrounding blocks. Three indoor air quality calls logged within three blocks in the last year, alongside 90 residential noise calls (76 for loud music or parties). In a compact 6-unit building, hallway odor bleed and street-level noise travel quickly through common shafts.
