MCI and IAI increases in NYC — explained

Español

MCI (Major Capital Improvement) and IAI (Individual Apartment Improvement) increases are two ways a landlord can seek higher rent in a stabilized unit for specific improvement costs. HSTPA 2019 significantly limited both.

Educational information about New York City rent rules — not legal advice. Rules change and every situation is different. For your case, consider consulting a licensed attorney or DHCR.

MCI — building-wide improvements

MCIs cover improvements benefitting the whole building (roof, boiler, elevator). MCI increases must be approved by DHCR and are subject to caps and amortization rules updated by HSTPA.

  • Increase generally capped at 2% per year of the tenant's rent.
  • Amortization period lengthened by HSTPA, reducing landlord recovery.
  • MCI increases end after 30 years under current rules.

IAI — improvements inside your unit

IAIs cover improvements inside your specific apartment. Under HSTPA, landlord recovery is much more limited and requires tenant consent for many items.
