If an owner expended up to or above $15,000 in IAIs on or after June 14, 2019, but before October 17, 2024,
the maximum rent increase that the owner may receive is based solely on $15,000 in accordance with the law
in effect at the time. If the owner did spend up to $15,000 in IAIs during that period, the owner may expend
an additional amount for new improvements made on or after October 17, 2024, based on the new $30,000 or
$50,000 aggregate. The owner may be eligible for a maximum rent increase equal to the difference between
$30,000 or $50,000, as applicable, and the amount for which the owner has previously received an IAI increase
since June 14, 2019.
B. Lease Requirements, and Registration and MBR Reporting
For rent stabilized apartments, any increase based on an IAI that was previously reported to DHCR in the
Notification Form and/or Tenant’s Informed Consent Form must also be reported in the next occurring annual
registration filing for the subject apartment. In addition, if the IAI items are installed during a vacancy, the
total costs are to be included in the rent calculations provided by an owner in the NYC Lease Rider or ETPA
Standard Lease Addenda. Supporting documentation such as invoices and bills may be requested by the tenant
from the owner. For rent controlled apartments, any increase based on an IAI that was previously reported to
DHCR in the forms above must also be reported in the appropriate Maximum Base Rent reporting forms.
