How It Works — MyStabilizedNYC

Step 01

Open the map

Head to the Map page. You will see a dark interactive map of New York City with colored dots — each dot is a rent stabilized building from the public registry.

The free preview lets you explore up to 1,000 buildings. Full building details require a paid account.

What the colors mean

Yellow — Multiple Dwelling A. Permanent residences. Most common.

Cyan — 421-A tax exemption buildings. Stabilized under a property tax deal.

Orange — Multiple Dwelling B. Hotels, SROs, rooming houses.

Pink — J-51 tax exemption. Most at risk of losing stabilization.

Step 02

Use the search bar to look up a street address or ZIP code. Filter by building type, or zoom and pan directly to the neighborhood you are researching.

Click any dot to pull up that building's information in a popup.

Step 03

Step 04

Always verify with the city

MyStabilizedNYC is a research tool. Use it to search, identify, and cross-reference buildings. For anything involving a legal or financial decision, always go directly to the official source.

Heads up: This map shows buildings registered in the public dataset. It does not confirm that every unit inside is stabilized, and data may not reflect the most recent changes. Always verify your specific unit directly with the city at hcr.ny.gov or call 718-739-6400. For legal matters, talk to a tenant rights attorney.

Next step after finding a building

Once you find a building you like, check hpdonline.nyc.gov to reach out to building management and inquire about available units directly.

FAQ

Common questions

Not necessarily. The map shows buildings registered as containing stabilized units — it does not confirm that your specific unit is stabilized. Some buildings have a mix of stabilized and market-rate units. Verify your individual unit's status directly with DHCR at hcr.ny.gov.

Not necessarily. The building may not appear in the 2024 DHCR building file, or geocoding may not have placed it correctly on the map. If you believe your building should be stabilized, contact DHCR directly. This map is a research starting point, not a definitive legal record.

Both are NYC tax exemption programs. 421-A was for new construction — owners received property tax breaks in exchange for including stabilized units. J-51 applied to buildings that underwent major rehabilitation. In both cases, when the exemption expires, the building can legally exit rent stabilization. These are the buildings most at risk of losing protected status.

Building data is sourced from the 2024 NYS DHCR building file and the NYC HPD registration database. We update the dataset annually when DHCR publishes new data. The current dataset reflects buildings registered as of late 2024.

One-time payment, permanent access. You get full building details including registered owner name, contact information, HPD registration data, stabilization program details, and access across all 5 boroughs. No subscription, no renewals. See our refund policy if you are not satisfied.

No. MyStabilizedNYC is an independent platform operated by ERLINNN LLC. We are not affiliated with, endorsed by, or connected to DHCR, HPD, the City of New York, or the State of New York. The data is public. We built the tool to make it actually usable for anyone researching rent stabilized buildings in NYC.
