If you own or manage multi-family property in New York City, don’t forget to complete your annual boiler inspection before December 31 for the 2025 Boiler Inspection Cycle.
New York City law mandates annual boiler inspections for multi-family properties (6+ units) and certain commercial and mixed-use buildings, with the 2025 inspection cycle ending on December 31. Any issues identified during the inspection must be corrected in a timely manner.
Annual Boiler Inspections
Low pressure boiler inspections must be conducted and inspection reports must be filed each year, before December 31, for H-stamped and E-stamped boilers (not HLW-stamped hot water heaters) in the following property types:
-
residential buildings with six or more families;
-
commercial and mixed-use buildings, regardless of boiler BTU capacity (NOTE: A mixed-use building has both commercial and 1-5 residential units);
-
any residential buildings classified as Single Room Occupancy (SRO) dwellings.
Low-pressure boilers with a heating input of 100,000 BTUs or less are subject to inspection when located anywhere outside a single apartment within a 6 or more residential occupancy, commercial, or mixed-use (commercial plus 1-5 residential occupancy) property, without regard to the number of dwelling units served.
A qualified professional, such as a Licensed Master Plumber or a Licensed Oil Burner Installer, must perform the inspection, and the report must be filed within 14 days of the inspection in the DOB NOW: Safety portal. Late filings can result in civil penalties, with a $50 per month penalty for late reports and a $1,000 penalty for failure to file after the late period ends.
Triennial Boiler Inspections
In addition to the annual boiler inspections filed with the DEP, Local Law 38 of 2025 amended requirements for DEP Boiler Registrations.
Applications for these registrations must be submitted every three years. Regulations vary for Boiler Registration 1 (units of 350,000 BTU/hr. to less than 2.8 million BTU/hr.) and Boiler Registration II (2.8 million BTU/hr. to 4.2 million BTU/hr.). Boilers over 4.32 million BTU/hr. require Work Permits/Certificates of Operation.
