showed up to do an estimate for a hot tub. There was obvious new work done to the basement. Homeowner says it was all inspected. Open the panel and 2-3 circuits pigtailed and put on one breaker, neutral and grounds terminated together etc. I tell the homeowner no way there was an electrical inspection. He hands me building a permit I do some research they passed a wood framing, a close-in, and got a 'final w/o U&O'. No electrical or plumbing. My question is should I do an estimate to fix the obvious problems including adding subpanel etc or should I just walk away and advise the HO to go after the previous contractor? Also I'm surprised they even got a final without to building inspector flagging the project for not having electrical and plumbing.
