What is Rent Stabilization?
Rent stabilization is a system that limits rent increases for tenants in certain buildings in New York City. It applies to buildings with six or more units built between February 1, 1947 and December 31, 1973, as well as buildings that received certain tax benefits (like 421-a or J-51).
Rent-stabilized tenants have the right to renew their leases, and their rent increases are limited to rates set annually by the NYC Rent Guidelines Board.
Data Sources
This website compiles data from multiple public sources:
- NYC Rent Guidelines Board — Annual tax commission data on rent-stabilized unit counts per building (2007–2017)
- NYC Department of Finance RPIE filings — Updated unit counts from property owner filings (2018–2023)
- DHCR Building Lists — Division of Housing and Community Renewal's official registered building lists by borough
Important Disclaimers
- This is not an official government website. Data is compiled from public sources and may not reflect current conditions.
- Building counts represent tax lot registrations, not individual apartment units available for rent.
- Some buildings may have been deregulated since the data was collected. Always verify with the building management or DHCR.
- Unit counts are estimates based on tax filings and may not reflect actual stabilized unit counts.
