What does “best-heat + M21 bus” mean on this page?

It’s a multi-filter match: buildings are filtered for strong heat performance signals and also grouped by proximity to the M21 bus corridor, so you can focus your search on both factors.

How many buildings are currently included?

There are 329+ eligible buildings on this page as of 2026-07-07.

Are the heat results based on inspections or tenant reports?

They’re based on Openigloo’s building-level signals and renter-reported information reflected in ratings. You should still confirm unit-specific details with the super or leasing office.

What should I ask the building about heat before applying?

Ask how heat is controlled in your unit, what happens during unusually cold days, whether repairs are handled quickly, and whether there are any known building-wide issues during winter.

Does a high heat rating guarantee the exact experience in my unit?

No. Heat can vary by apartment layout, floor, and exposure, even within the same building. Use the rating as a starting point, then verify for your specific unit.

Is there anything in the lease I should watch for related to heat?

Confirm whether heat is included in the rent and how any related utility charges are handled. Also ask whether any maintenance or thermostat practices could affect your day-to-day comfort.

Where do I verify details that ratings might not capture?

Use Openigloo to shortlist, then confirm directly with the building about heating equipment, maintenance, and winter procedures. If possible, ask for the building’s documented policies for heat complaints and repair timelines.
