The tax assessors office would also be a good place to check as they assess properties based on square footage. Additionally, should you ever want to sell and there was never a permit pulled you would only be able to declare the original square footage which is technically all this seller is entitiled to.
If he's listing it as a 3ksf home and it's original footprint was only 2500sf then technically that's all he can really claim in the listing. Another thing you may want to do is go to the City building jurisdiction and find out what the parameters would be for an "AS BUILT" permit. They may want to take a look at the foundation just to make sure it was done properly. This would require some destructive inspection whereby it would be necessary to dig a hole down to the bottom of the footing to verify footing depth. and to remove some drywall on the inside or some stucco or siding on the outside to verify proper tie down and anchor bolting patterns.
A note of caution, however, don't be surprised if they don't have a copy on file. Even in their microfish. I deal with permits on old structures daily and you'd be surprised how many get tossed after a decade or so.
my next question is, is there an advantage of having the psychical permit? If so, i'll have to go thru a bunch of microfilm to find it from the county since this was from 1975.
With buying homes without contingency, it's been the norm in the bay area to be more competitive with 20 to 40 offers on a home. We went to the house and everything looked perfected. In the disclosures, there were no section 1 items which we thought was also good.
All in all, if we can purchase the house without a permit, would that be okay? Without a permit on that addition, are we able to purchase Home owners insurance? I know if there are no permits for some areas, we won't be covered but can we get insurance on the permitted areas?
Can we still back out if we have not signed the agreement or the contract?
