Why New York Landlords Need a System

New York landlords face a regulatory environment with no parallel anywhere in the country. Three distinct layers of rent regulation can apply to a single building simultaneously — the Rent Stabilization Code for buildings with 6+ units built before 1974, the statewide Good Cause Eviction law (mandatory in NYC, opt-in elsewhere), and the sweeping changes from the Housing Stability and Tenant Protection Act (HSTPA) of 2019. Understanding which rules apply to your property requires knowing its construction date, unit count, location, and rent history.

The Rent Guidelines Board just froze rents at 0% for the 2026–27 lease renewal cycle, affecting roughly one million rent-stabilized apartments across New York City. For landlords already operating on thin margins, a rent freeze means every other cost — insurance, maintenance, property taxes — must be absorbed entirely. Good Cause Eviction adds a separate cap of CPI + 5% (or 10%, whichever is lower) for covered units, and it became mandatory in New York City while approximately 19 other municipalities have opted in statewide.

HSTPA permanently eliminated vacancy decontrol, meaning units can never exit rent stabilization regardless of how high the rent climbs. Vacancy and longevity bonuses are gone. Individual Apartment Improvement (IAI) increases are capped at $15,000 over 15 years, and Major Capital Improvement (MCI) increases are capped at 2% annually. These changes made cost recovery from building improvements far more complex than it was before 2019. LeaseBase tracks which regulatory layers apply to each of your properties, calculates your maximum allowable increases under each applicable law, and alerts you to RGB renewal deadlines, GCE notice requirements, and fee limits before you make a costly mistake.
