Hi all,How much should it cost a plumber to re-plumb kitchen so that dishwasher hookup is under the sink?

I would tell the tenant only that she is obligated to follow local noise regulations and if she is doing this she is fine.

Depending on plumbing and electricity installations, it can go from 50k to 100k.

I don't have anything to offer with your question beyond what everyone else has said but I just want to let you know some general rules with foundations:1. crawlspace - cheapest to repair, good for plumbing because they can run underneath the house and easy to repair, bad for really cold days, pipes could freeze, some people complain about moisture in crawlspace and tile cracking but that's a long term issue and you may not have to deal with that and if you do, just lay LVP2. slab - second cheapest to repair generally, worst for plumbing because to fix, you have to often remove flooring and drill into the concrete to fix leaks and I've had a house that I played whack a mole with an active leak3. basement - most expensive to repair, okay for plumbing, but your basement could leakIMO crawlspace is the gold standard for foundation for rental investments in older properties (older than 1950s).

You state regulations should guide you.

Permits, totally depends on the city, ie some city charge 25/fixture and some charge 10/fixture on plumbing, you're looking at 3-5k.
