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.
