An 1850s Boerum Hill townhouse traded to an LLC after a spring heat cluster.
A single-family Boerum Hill townhouse built in 1853 that recently changed hands twice in four years, ending in a March 2026 sale to an LLC. Because it's a single home, standard apartment filings are sparse, but recent heat reports and block activity give clear operational signals. Three things to know:
A cluster of heat calls hit the house in spring 2026. Five heat and hot water complaints came in between March and May 2026. For a single-family home, building-wide heating calls usually point directly to boiler failure, fuel delivery issues, or burner controls needing overhaul.
Two sales in four years ended in an LLC buyout. The house sold for $3.7M in January 2022 and traded again in March 2026 for $3.625M to an LLC. Brief holding periods followed by corporate acquisition often signal planned conversion, rental intent, or capital re-allocation.
Parking issues dominate the surrounding three blocks. 681 illegal parking calls were logged within three blocks over the last year, driven mostly by 322 blocked hydrants and 157 posted sign violations. Curb space on the surrounding blocks stays tight and heavily managed.
