Hi all, is it required that when I replace my old gas water heater that I obtain a permit? So my old water heater is giving me brown waters, it's pretty old already so I think it's time to replace it. I called up home depot and their local contractor guy quoted me $2600(!) for the new heater, replacement, and permits. Now I'm not an experienced plumber but that sounds pretty high for replacing a water heater. I can see ones for sale at home depot for $600-800, and it would only be a few hours of work to remove the old one, plug in the new one and connect all the pipes to make sure nothing leaks. It definitely shouldn't get up to $2600.
The only thing I'm unsure about is the permit. If I want to do the replacement myself or buy the new heater and hire a plumber to do it, do I need a license? I mean it's not like a government official will have to come in and see me replace the heater right? How does this work? Can I just hire a good plumber to replace the heater and forget about the permit? Surely the permit isn't $1000?
I live in NYC if that changes anything for the permit.
