Apartment hunting in NYC is brutal. We make it a little fairer.

SnagFlat flags the listings that are likely rent-stabilized — and which way they face the sun — right on StreetEasy. Scan a whole results page instead of opening forty tabs.

What you see on every listing

Small badges next to each listing. Click any one for the basis, the data source, and an honest caveat.

Is it rent-stabilized?

We check public NYC records for registered rent-stabilized units and J-51 / 421-a tax benefits that require stabilization — and tell you the basis, like “55 of 68 apartments registered.”

Orientation

Which way the building faces — and whether a south exposure is even possible.

Sun hours

Estimated direct sunlight on the equinox, ray-cast against neighboring buildings — tailored to the floor.

Street character

A quick busy-vs-quiet read from the street, so a corner avenue doesn't surprise you.

Average unit size

The building's average residential unit size from public records — context, not a promise about this unit.

Why you can trust it

Honest about what we can't know.

A confidently wrong badge is worse than an honest “unknown.” You're making a housing decision — so we tell you the basis, not just a verdict.

- Building-level, not unit-level. We can say a building is registered as stabilized; the public data can't guarantee a specific apartment.

- The data lags reality. Public records are updated on their own schedule, so a badge can be a year or two behind.

- “Unknown” is a real answer. When the records are inconclusive, we say so instead of guessing.

- Informational, not legal advice. Use it to triage and ask better questions — then verify before you sign.
