Creates NYC requirements for cooling-tower registration, inspection, testing, cleaning, disinfection, and annual certification.
New York City jurisdiction · Sources checked September 15, 2026. Law numbers repeat by year. These educational summaries are not legal advice or a complete compliance checklist. Later amendments, agency rules, building characteristics, and effective dates determine the requirements for a particular property. Use the linked City sources to confirm current obligations.
Why it matters
The compliance record should connect the registered equipment to its maintenance and testing documentation. An equipment service invoice alone does not establish that every required step or annual certification is complete. Removal and permanent discontinuance also require attention to the City’s notification requirements.
In practice
A project example
During an acquisition, the buyer reconciles the roof equipment inventory with registered towers and requests the associated water-management, service, testing, and certification records.
