I am renovating a house into 4 bachelor apartments. I have hred a contractor to do most of the work. He wants to do the plumbing. Do I have to hire a plumber with a license to do the work?
Depends where you live. If you are the home owner, you don't need a licensed plumber .. as long as you are the only person doing the work.
The other person working can not work on plumbing that exceeds 3-5' in Ontario.
Unless, your contractor is very experienced at plumbing, I would get a licensed plumber to do the plumbing. There will be water supply, drain as well as venting issues that will need to be addressed. These need to be done by code before the walls are closed up. A plumber may cost more money now, but think of the problems later for you and your tenants if the plumbing isn't done right! We have all seen our share of bad plumbing. Such as waste water not draining properly, bad swear smell, etc. You can do a Google search or check with the building department so see if a licensed plumber is needed. I suspect with the scope of work, you probably need a permit.
Yes you should always hire a Red Seal Licensed Plumber( newest licensing for plumbers in Canada) under the Ontario college of trades. Meaning, they will know all the updated codes and regulations. Also, if your hiring a plumbing company to do the work and if your municipality requires plumbers to work in your area then they will need to have there plumbing contractors license as well as there master plumbing license if required by the municipality. Otherwise, a licensed plumber is more than qualified to do the rough in and finishing work. There is a huge liability when it comes to plumbing, electrical, structural, and Hvac. You should always hire Licensed professionals.
