Plumbing permit and related trade permit check for water heater or boiler work
Boston's water heater and boiler guide says putting in a new water heater or boiler requires a contractor who can apply for a plumbing permit and perform the work. The same guide lists the plumbing permit path for replacing or installing a water heater or boiler when no other work such as opening walls is needed, so projects with electrical, gas, wall-opening, boiler, venting, or structural scope should be checked for additional Boston trade or building permits before work starts.
