A technical fix to New York's Good Cause Eviction Law changes when the 30-year exemption clock starts—and it matters most to owners of mixed-age buildings.
Most New York landlords know that buildings with a Certificate of Occupancy issued on or after January 1, 2009 get a 30-year exemption from good cause eviction protections. What many don't realize: that exemption just got narrower, and the change takes effect immediately.
Senate Bill S08612, which relates to technical changes to the Good Cause Eviction Law, rewrites how and when that exemption applies. The key shift is moving from a building-wide exemption to a unit-by-unit one.
Under the old rule, if your building received its CO on or after January 1, 2009, every unit in that building was exempt from good cause eviction requirements for 30 years from that date. Simple, but blunt.
S08612 changes this. The exemption now applies at the individual unit level. More importantly, the 30-year clock for each unit starts from whichever comes first: the temporary Certificate of Occupancy or the permanent Certificate of Occupancy for that specific unit—not the building as a whole.
This matters most to owners of mixed-age buildings. If you own a property where units received COs at different times, or where some units are older conversions and others are newly created, the exemption window now varies by unit. A newly created unit in an older building will have its own 30-year exemption period, anchored to when that unit got its CO.
This change primarily impacts:
If you own a single-family home or a building where all units received their CO on the same date, the practical impact is minimal. But if your portfolio includes conversions, subdivisions, or phased developments, you'll need to track the CO date for each individual unit going forward.
S08612 takes effect immediately. Critically, it applies to all actions and proceedings filed on or after the effective date. This means disputes over eviction eligibility will be evaluated under the new unit-level standard from now on. Existing disputes may still be governed by prior law, but any new case will use the updated rule.
The amendment is codified in Section 2 of the bill, which modifies subdivision 8 of section 214 of the Real Property Law (pages 2–3 of the bill text).
If you manage or own property in New York, audit your portfolio for mixed-age units and confirm the CO dates at the unit level, not just the building level. This documentation will be essential if good cause eviction protections ever come into question. Your property management system should track these dates by unit, not by building.
The change is technical, but the operational shift is real. Understanding it now prevents confusion later.
