Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent reviews of buildings managed by BLACK DIAMOND EQUITY MANAGEMENT INC reveal mixed experiences with management. Tenants commend spacious units, affordable rent for the areas, and responsive superintendents who provide decent service. However, recurring issues include inconsistent cleanliness, poor garbage management, persistent pest problems (especially roaches and rodents), and occasional neglect of building upkeep such as mold and outdated appliances. Management responsiveness varies, with some renters reporting slow or inadequate responses to maintenance and pest control concerns. Noise levels and neighbors also vary by building, with some finding a quiet environment and others facing disturbances. Improvements in cleanliness, pest control, and maintenance responsiveness are frequently advised.

Reviews

Former tenant·5 minutes ago

not the worst

Pros

cheaper for the kips Bay Area. good size rooms , central air

Cons

occasional roach, the cleanliness isn't kept up with. but my unit is pristine since im so clean so u win some and lose some. the bathrooms vents are fake so mold grows in bathrooms

Advice to the owners

clean more

Former tenant·8 months ago

Just OK. livable but not great

Pros

Cheaper rent for the area i guess

Cons

Occasional on and off roach issues. Never a full blown infestation in my unit - but see a roach here and there. Failed local 11 law so balconies have been closed down since April of 2024 with no end in sight and loud construction. Mold issues through out the building. Very dirty vents in hallways

Advice to the owners

Actually take care of the building
