Plumbing and gas permits in Weymouth come from the Department of Municipal Licenses and Inspections on the first floor of Town Hall, 75 Middle Street, 781-340-5004. The office is open weekdays from 7:30 to 3:30.
The inspectors are in the office from 7:30 to 9. The department says an inspection can usually be set up for the same day by calling in that window.
The fee schedule that took effect July 1, 2024 lists a gas water heater at $40. A plumbing permit is a $20 application fee plus $20 a fixture. A reinspection is $100, and an inspection after hours is $200.
The plumbing and gas applications are forms posted on the department's Applications and Fees page. The plumber fills them in.
Weymouth has about 26,700 housing units, and a third of them are in buildings with five or more. If the heater is in a closet on an upper floor, the leak lands on a neighbor.
Weymouth does not take MWRA water. It draws from Great Pond and from wells in the Mill River basin. The town's reports do not give a hardness figure, so ask the water department for it. Why the number matters to a tank.
National Grid supplies both gas and electricity. For a gas smell, leave and call 911, then National Grid at 800-233-5325. Mass Save's 2026 rebate on a heat pump water heater is $750.
Call the Weymouth Health Department at Town Hall, 781-340-5008, and ask for an inspection.

No. This is an independent referral site for Weymouth. Calls go to a local licensed plumber. Ask for the license number on the call.
Turn off the cold water supply valve on top of the heater, then shut off the gas valve or the breaker. Put towels down and move anything valuable off the floor. Then call.
The landlord's. Massachusetts requires landlords to supply hot water and to fix a failed heater promptly. Shut the valve, photograph the leak, and notify the landlord in writing today. If you need the number for a plumber because the landlord asked you to arrange it, that is what this line is for.
Usually the unit owner for the heater itself and any damage inside the unit; damage to units below or common areas goes through the association's master policy and your HO-6. Document everything before the plumber removes the old tank.
Yes. Massachusetts requires a plumbing permit (and a gas permit for gas units). A plumber who says you do not need one is a warning sign.
No. You pay the plumber directly for any work you agree to.
