648 Warren Street, Brooklyn

A three-family Park Slope townhouse under long-term family ownership, marked by recurring paperwork filings and street-level corridor friction.

A 1998 three-family townhouse in Park Slope held by the Charlemagne family since the late 1990s. The building's operational file carries open administrative paperwork items, while the surrounding blocks experience street-level curb friction and air quality complaints. Three things to know:

Administrative compliance lags behind on paper. The house carries eight open violations, driven entirely by repeating administrative paperwork gaps—specifically annual bedbug report filings and missing property registration statements. The file carries zero open class C hazardous conditions or active tenant-reported code cases.

Air quality and curb parking dominate nearby calls. Within three blocks, residents logged 11 indoor air quality complaints over the last year, alongside 245 illegal parking calls that concentrate heavily around blocked crosswalks and hydrants. Air quality and vapor calls can reflect HVAC or exhaust bleed from nearby commercial spaces.

Quieter signals on this building and the blocks around it:

• 114 noise calls occurred within three blocks last year, primarily off-hours construction work.
• Only two building-specific calls exist on file, both closed sanitation tickets.
• The property deed has remained in the family since 1998.
