In Florida, the new FAR offer and purchase contracts are very specific that the seller is responsible for not only obtaining permits for any work done on the property, but also for making sure any permits are closed out. In fact, in the latest version, after the blanks (1.5% of purchase price if left blank) for repairs and for wood destroying organisms, there is a similar blank for obtaining/correcting permit issues.
As part of our preparation for a listing appointment, we get a copy of the property's permit history from the city or governing body. That not only helps us correlate an enclosed porch or a new roof, it also gives us the opportunity to discuss all this with the homeowner, so they can begin any corrective action early, before there's a time crunch.
We also obtain this when we represent a buyer - if not before we make an offer, then as soon as possible afterwards. We'll share this information with the home inspector.
This is just one more opportunity to give value to our clients.
