NYC Rental Apartment Building Renovations

Apartment Improvements

Apartment Improvements


Under New York's Rent Stabilization Laws, landlords may increase rents when they make qualified Major Capital Improvements (MCI) to a building or Individual Apartment Improvements (IAI). The law requires landlords to follow certain rules and guidelines when increasing rents based on MCIs or IAIs, and it provides an avenue for tenants to dispute rent increases they believe were made unlawfully.

Difference Between MCI and IAI


  • MCI - Owners can apply to HCR for approval after improvements have been made on a building. Any increase in rents is based on the actual, verified cost of improvement or installation. Some examples of MCI items include boilers, windows, electrical rewiring, plumbing and roofs. See Fact Sheet #24: Major Capital Improvements QA
