As mentioned below, if your home was listed with an agent, the agent should have followed local ordinace re: CCO's (continued certificate of occupany) and many towns also require CCR's ( code compliance reports) which includes all permits open or closed on a property. Not only is a seller asked on the disclosure forms about additions, most of them all say "with all permits".
We run into problems with getting CCO's now before closing since many towns have revised their ordinances and make inspectors check on the tax card what has been updated, they then set up building inspectors to come out and make sure all the work was done up to code. If not, they will allow the property to close but there is 90 day time period for the work to get done and reinspected.
Your best bet, have the town come in and reinspect, there is a good chance all the work was done properly and they will issue you all the permits you'll need if you go to resell your home. If the property was purchased with a real estate agent, you have proof from the MLS sheet, take that to the building inspector, this shows that you purchased it already done. They may not make you pay for the permits.
You can try the route of going against the home inspector but it is likely that the property inspection forms you signed with your inspector addressed the fact that they are not hired to point out or identify code issue - although it's common for inspectors to identify the problem while they are there.
As mentioned before, consult your attorney. Gather your paperwork up.
The saying about "Caveat Emptor" (let the buyer beware) should tell you that what the seller may be trying to save is not always just the commission!
Home inspectors are not the same as "Code Inspectors" and most of them have disclosures in their reports that cover that topic. When a Realtor lists a property, there is also a statement signed by the seller that the information is correct to the best of their knowledge and that is what the Realtor goes from.
So: Check your purchase agreement. And, as appropriate, consult an attorney.
Also, did you have a home inspection done? That might have also uncovered the non-code work done. Check your home inspection and--depending on what the non-code items are--you might also have recourse against the home inspector.
Hope that helps.
