Do I need to be a licensed plumber to replace a toilet in New York CIty?

No,you can replace it.Make sure your new toilet has space from the wall behind it,at least 1 inch.Scrape off old wax ring residue replace flange if needed.Just be carefull tightening bolts as you can easily crack the ceramic

I've done quite a few toilet replacements in several different states, etc. and have never run into any "code" for replacing a toilet. However, if you were to do it yourself, make sure your confident in what your doing, there can be a tremendous liability to you if you were to cause a leak which damaged your unit...and even worse several other units.

For your own home, no. But if you do jobs like that for others, and charge for it, then you're considered a plumber, and better have your license handy. You can also replace pipes in a home you own, but in somebody else's (or a rental unit), you better know the codes.

I DONT BELIEVE SO, BUT DO U HAVE TO CONTACT THE CO-OP IF U DO THOSE KIND OF JOBS?

OF COURSE U ARE IN NYC????????????????THEY MAY WANT TO GET THEIR MONEY ALSO FOR OT USING UNION HELP

No you can replace it if you feel comfortable doing it.

I'll do it for $500.

believe its legal to change it yourself , provided you know how
