Good cause buildings near the M21 bus in Manhattan

It’s a tenant-protection category used to find buildings where certain rent increases and non-renewal actions can be limited under applicable rules. The page helps you start with eligible buildings, but each building’s specific situation can vary—confirm directly.

It’s a location filter designed to surface buildings close to the M21 route. Distances can be approximate, so check the exact stop closest to the unit and your typical walking route.

Openigloo shows 1,806+ eligible buildings in this scope, as of 2026-07-07.

No. The filter is about eligibility under applicable rules, not a guarantee of renewal or fixed rent outcomes for every lease cycle. Ask the building to explain renewal and rent terms for the specific unit you’re considering.

Ask for the renewal policy, any planned rent changes, how notices are handled, and whether there are building-wide practices that affect renewals. Get answers for the exact apartment, not just the building in general.

Usually you’ll see the asking rent, but the FULL move-in cost (for example: deposits and any required fees) still matters beyond the monthly rent. Confirm the total cash-to-close and any recurring costs before committing.
