To keep buildings safe, owners of properties higher than six stories must have exterior walls and appurtenances inspected every five (5) years – and they must file a technical façade report with the Department. See NYC Construction Codes §28-302.1 and RCNY §103-04. The current Façade Rule was last revised on November 11, 2021. See FAQs for information on 1RCNY 101-07 and 1RCNY 103-04.
