1. What Rent Stabilized Law Regulates
Covered Apartments and Buildings
A rent stabilized apartment is generally defined by the age of the building and the number of units it contains. Typically, buildings constructed within specific mid-century windows containing six or more units fall under this protection. However, newer buildings may also be subject to rent stabilized law if the owner has accepted government tax benefits or subsidies in exchange for adhering to rent limits.
Scope of Rent Regulation
This legal framework does not merely "freeze" rent; it regulates the rate of change. The law dictates that rent increases are restricted to percentages established by designated housing boards or legislative mandates. Courts apply rent stabilized law to enforce statutory rent limits and prevent unlawful rent increases. These regulations also prohibit the addition of unauthorized surcharges or "hidden fees" that would effectively push the rent beyond the legal limit.
2. Tenant Rights under Rent Stabilized Law
Lease Renewal Rights
The cornerstone of tenant protections is the right to a lease renewal. Under rent stabilized law, a tenant in good standing has a statutory right to renew their lease for a one- or two-year term at their option. A landlord can only refuse a renewal under extremely narrow, legally defined circumstances, such as "owner occupancy" or a proven "holdover" violation.
Limits on Rent Increases
The "burn rate" of a tenant's housing costs is strictly controlled. Increases are only permitted:
- Upon Renewal: At the rates approved by the governing board.
- For Major Improvements: When the owner performs significant, building-wide capital improvements (MCIs) or individual apartment improvements (IAIs), provided they meet rigorous documentation standards.
- By Vacancy: Under specific statutory formulas that have become increasingly restricted in recent years.
3. When Violations of Rent Stabilized Law Occur
Rent Overcharges
A rent overcharge occurs when a landlord collects more than the "legal regulated rent." This often stems from an unlawful rent increase disguised as a renovation cost or a simple accounting error. SJKP LLP performs a surgical review of the “rent history”(a multi-year record of the unit's financial life) to identify jumps in rent that lack a statutory basis.
Improper Deregulation Claims
Deregulation is the process by which an apartment is removed from the rent stabilized system. Many housing disputes center on whether a unit was "lawfully" deregulated. In the current legal environment, many previous "off-ramps" for deregulation have been abolished. If a landlord treats a stabilized unit as "free market," they may be exposing themselves to terminal civil liability and the requirement to restore the tenant’s protected status.
4. Landlord Obligations under Rent Stabilized Law
Registration and Disclosure Duties
Owners must register every stabilized unit annually with the designated housing agency. They are also required to provide every new tenant with a "Rent Stabilization Lease Rider," which details the prior rent and the reason for any current increase. In rent stabilized law disputes, courts and agencies examine rent histories, registrations, and statutory compliance. A failure to register can result in a total rent freeze, preventing the landlord from collecting any increases until the default is cured.
Compliance with Rent Limits
Landlords must ensure that the "preferential rent" (a rent lower than the legal limit) is handled correctly. Under many modern statutes, once a tenant is given a preferential rent, that rent becomes the base for all future increases for the duration of the tenancy. Attempting to jump back to the "legal" rent at renewal is a common, and often unlawful, tactic.
5. How Rent Stabilized Law Disputes Are Resolved
Administrative Complaints
Many housing disputes begin with a filing at the state or local housing agency. These agencies have the power to audit rent records, order refunds, and decrease rent if essential services (like heat or elevator access) are not maintained.
Court Enforcement Actions
While agencies handle the "numbers," courts handle the "possession." If a landlord initiates an eviction against a stabilized tenant, the court must first determine if the landlord has complied with the underlying rent stabilized law. If the landlord has overcharged the tenant or failed to register the unit, the entire eviction proceeding may be terminally defective.

7. Remedies for Rent Stabilized Law Violations
Rent Refunds and Penalties
The primary remedy for a rent overcharge is a refund of the excess rent paid. However, if the overcharge is found to be “willful”(meaning the landlord cannot prove it was a good-faith mistake)the court may award treble damages (three times the overcharge). The landlord may also be ordered to pay the tenant’s attorney fees.
Injunctive Relief
In cases where a landlord refuses to offer a lease renewal or threatens to shut off utilities, the tenant may seek injunctive relief. This is an emergency court order that forces the landlord to stop the harmful conduct and maintain the status quo while the legal dispute is adjudicated.
