NYC Occupied-building Work: Permits, Harassment and Tenant Protection

The one meaningful exception is work in a wholly commercial building with no residential units at all, which may require an Occupant Protection Plan instead, a related but distinct filing.

3. Tenant harassment: conduct during the work carries its own exposure

Separate from any permit or plan, specific conduct during a renovation can independently constitute tenant harassment under NYC's Administrative Code. This law was originally enacted in 2008, providing injunctive relief as a remedy, and was significantly expanded in 2017 to add monetary damages, punitive damages, and attorney's fees as available remedies as well. That expansion matters directly for occupied-building work: a project that's fully permitted and technically compliant with the Tenant Protection Plan can still generate a harassment finding if tenants experience specific conduct during the work as coercive or as an attempt to pressure them out.

Because construction inherently involves noise, dust, and temporary disruption, the line between legitimate project impact and conduct that crosses into harassment isn't always obvious from the contractor's side. This is genuinely a legal-review question rather than something a general overview can resolve for a specific project; the severity of any remedy has been described as tied to the severity of the underlying conduct, which means the analysis is fact-specific in a way this article isn't positioned to walk through project by project.

4. Major Capital Improvements: building-wide work, with the tenant staying

If any unit in the building is rent-stabilized, work to building-wide systems, boilers, windows, electrical rewiring, plumbing, roofs, generally falls under Major Capital Improvement rules rather than the individual-unit process described next. MCI work assumes the tenant remains in place throughout; it isn't a mechanism for ending a tenancy, it's a cost-recovery mechanism.

Before collecting any rent increase tied to MCI work, the landlord needs state approval, and stabilized tenants receive notice of the application with an opportunity to respond before it's granted. The resulting increase is capped at 2% annually and has to be removed from the rent entirely 30 years after it takes effect. An owner who misses the window to apply the increase, within 120 days of the lawful collection date or the next lease renewal, whichever is later, can lose the ability to collect it.

5. Individual Apartment Improvements: unit-level work needs the tenant's consent

Work inside a specific stabilized unit, rather than the building as a whole, generally falls under Individual Apartment Improvement rules instead. Unlike MCI, IAI work doesn't require state pre-approval before the landlord can collect an associated rent increase, but for an occupied unit, it does require the tenant's written, informed consent, filed on a specific form with before-and-after documentation of the work.

This distinction matters because landlords sometimes assume that because IAI doesn't need pre-approval to collect the increase, it also doesn't need the tenant's agreement to do the work in the first place. It does, for an occupied unit specifically. Proceeding with interior work in an occupied stabilized apartment without that documented consent creates exposure on the rent-recovery side even if the physical work itself is otherwise permitted and compliant.
