Legal Regulated Rent
The maximum lawful rent for a rent-regulated unit, registered with the state and built up from a base plus permitted increases.
The legal regulated rent is the highest rent a landlord may lawfully charge for a rent-stabilized or rent-controlled apartment. It is constructed from a registered base rent plus every permitted increase layered on over time — RGB renewal orders, vacancy increases where allowed, and capped MCI and IAI surcharges.
For stabilized units the legal rent is registered annually with DHCR, and the registration is the system of record in an overcharge dispute. A landlord who charges above the legal rent — or who can’t document how the legal rent was built up — is exposed to overcharge claims with a multi-year lookback under HSTPA.
The legal rent is distinct from the rent actually charged, which may be a lower preferential rent. Both numbers matter: the legal rent is the ceiling; the preferential rent (where one exists) is usually the base the next renewal works from.

- Rent ControlThe older, smaller of NYC’s two rent-regulation systems, covering a shrinking set of long-occupied pre-1947 apartments.
