The Rental Housing Registration Data Integrity Temporary Amendment Act of 2026 amends section 205 of the Rental Housing Act of 1985 to enhance reporting requirements for owners of rental accommodations that are exempt from rent stabilization. Specifically, the bill mandates that these owners provide detailed information at the time of registration, including the current monthly rent amount, the rent charged for the same unit during the previous two calendar years, and a list of utilities, facilities, services, and appliances associated with the rental unit. This new requirement is outlined in a newly added paragraph (5) to section 205(f).

Additionally, the bill clarifies that the information required under this new provision will only need to be submitted at the time of registration and will not be subject to ongoing or annual reporting requirements. The act is set to take effect following approval by the Mayor and a 30-day congressional review period, with a provision for expiration after 225 days from its effective date.
