You'll need to go to the county permitting office. They will have maps of all known surface faults in the area. You should have the plat-map for the area. If you don't have that try using the properties legal description.
All new construction in areas known to have surface faults are required to have geological studies done. This is where they dig a hole 8 feet deep the entire length of the proposed construction plus 50 feet each side.
Compaction, percolation and other soils studies are needed for pools, driveways, foundations, septic systems ..... etc.
I didn't look at the age of your house so it may have been built prior to the newer codes. Not all counties or for that matter the person behind the counter in the county office is going to require the same thing.
Talk with the neighbors (plural as in 20+), talk with the HOA, call your insurance agent and give them the address. They will know if there are any problems in the neighborhood.
An owners disclosure is the last thing I'd rely on as proof of a problem free house. The seller and agent are long gone with your money from the sale while you're left to deal with the problem, litigation, and insurance claims to remedy the situation.
