Permit code violation on closing day

[Poppy Rae]

My contractor didn't pull permits On a renovation but the renos are done.   On closing day,  I stopped by the property and saw a Stop Work order from the city.   ****** situation but in any case we plan to see the permits through.  The buyer still wants the house and he wants to close ASAP.  The city said it would be about 6-8 weeks to close out the permits.  What risk do we have with closing out the permits after the new own takes over?  He'll be the "home owner" now so I'm concerned he'll take over the relationship with the new contractor we hired to finish the permits and we'll just be funding an endless amount of work.   Any advice? Sell it and then rectify it? or cancel contract,  finish the permits and then relist the house in 6 weeks?  We had 3 offers on it,  so not too worried about relisting.  Thanks
