Yes I too am curious, If your building inspector did not find truly hidden defects then how was the report for the affected things worded something to the effect of `all basement walls covered in dry wall, no visible water stains` or is it something like a central air unit thats too small ? if thats the case then what does your report state ? So you know, upgrades that are things like new carpet , new kitchen cabs , new appliances , new woodwork and doors are things that may not even have needed permits depending on if your city / county does a dollar threshold as a trigger for when permits are needed. SO what was it you think was missed ?
