Replacing a water heater in Dedham.
In Dedham, a replacement gas water heater needs both a plumbing and a gas fitting permit, pulled by licensed trades. In the past, one flat fee covered both ($40 on the older posted sheet). Starting work without a permit triples the fee. Eversource supplies both electricity and gas.
