So you might have carried forward some of these and at sale you won't get the hit - but only your tax preparer professional would know that for certain.Maybe @Dave Toelkes can offer his opinion - he has gone through the tax code with a fine tooth comb it seems ;)

I would also talk the most experienced local building inspector about anything that they will expect getting all inspections approvals including a final.  

The rental cert. office sent me a letter the other day to inform me of a hearing that I have to attend where they will determine if I am still in violation and then asses me a fine of up to $5,000.
