Boiler / Unfired Pressure Vessel Permit + Annual Certificate of Inspection: Washington, D.C. restaurant guide
Department of Buildings (DOB)
What it is
New or relocated boilers and unfired pressure vessels need a DOB permit and inspection before approval, and every boiler must be inspected at least once a year by DOB or a DC-licensed boiler insurance company to get the posted annual Certificate of Inspection.
When a restaurant needs it
Installing or replacing a boiler, a large water heater classed as a boiler, or a pressure vessel.
How to apply
Your licensed contractor pulls the Miniature Boiler / Unfired Pressure Vessel / Fuel Burning Equipment supplemental permit on Citizen Access; schedule the inspection with DOB at (202) 442-9557 or through your boiler insurer.
Documents you’ll need
- Contractor's DC trade license
- Equipment data plate/ASME stamp
- Main building permit number
Good to know
DOB's boiler page and its fee schedule disagree on the annual certificate ($50 vs $33); confirm when you schedule. Post the certificate in the boiler room.
