1. Check if your boiler is required to have a PTO
There must be an active PTO on file for a six unit or more with one of the following:
- More than 200,000 total BTU capacity for boiler or tankless water heaters (single or combined)
- More than 120 gallons of storage tank capacity (single or combined)
If combined units are used in series, each unit will need a separate PTO application.
For more information and to see if your property or building meets our requirements, you may view our Permit to Operate Boiler Criteria Checklist.
2. For C-4 contractors: Log into the online system
If you don’t have an account, you can create one by registering with the City of San Francisco as a licensed contractor.
The system will only show you permits you can obtain with your trade license.
You will provide us information about the boiler you are operating. You can pay and immediately get your PTO online.
