San Francisco Boiler System Permit to Operate Compliance FAQ

The San Francisco Department of Building Inspection regulates boilers throughout the city. As boilers are heat generating devices that use pressure to distribute energy, proper maintenance is key to prevent explosions that could result in death, injury, and property damage.

No. Compliance is mandatory. The city expects all eligible property owners and managers to self register for the program. Failure to do so may result in fines from the city; it also opens property owners and managers to potential litigation should injury or property damage result from an accident caused by an improperly maintained system. If your boiler is not registered, you can do so here, or have ACE register it for you as part of our PTO inspection and compliance service.

If your boiler meets ANY of the following criteria, you must comply with the PTO program:

Building Size

– 6+ Residential or Commercial Units heated by a single boiler or combined system

Boiler System

– Single or combined boilers or tankless water heaters that exceed 200k BTU capacity

– Singular or combined volume of storage tanks that exceed 120 gallons

– If combined units are used in a series, each unit will need a separate PTO

Boiler Types

Low Pressure Hot Water Heating Boilers furnish hot water at pressures not exceeding 160 p.s.i. and at temperatures not exceeding 250°F

Low Pressure Steam-Heating Boilers furnish steam at pressures not exceeding 15 p.s.i. (U.M.C. – 214.0)
