What does the “good cause” filter mean on this page?

It’s a tenant-protection category that limits certain rent increases and non-renewals compared with buildings not in the category. Requirements can vary by situation, so confirm the details for your lease with the building.

How does “near the M21 bus” affect which buildings show up?

It narrows results to Brooklyn buildings along the M21 corridor area so you can prioritize day-to-day transit access. Still check the closest stop and your typical walking route.

How many buildings match these filters right now?

There are 72+ buildings on Openigloo that match the good-cause + M21 bus scope as of 2026-07-07.

Does this page guarantee availability in every building?

No. The page is scoped by building and filter eligibility. You’ll still need to check which buildings currently have apartments advertised and match your dates.

What should I ask about good cause before signing?

Ask how renewals and any rent changes would be handled for your unit and term, what documentation applies, and what notice timelines the building follows for your situation.

If I see a lower asking rent, what else should I budget for?

Look at the full monthly and move-in costs: deposits, broker/agent fees if applicable, utilities, and any building charges. The total cost can differ even when two units have similar asking rents.

Which neighborhoods are trending in this Brooklyn scope?

Bushwick with 12,589+ buildings; Stuyvesant Heights with 7,834+ buildings; Park Slope with 7,025+ buildings; Flatbush with 5,564+ buildings; Downtown Brooklyn with 3,920+ buildings.
