What could/should a homeowner do if they just found out that their home has no building permits. The only permits that come up are for a Agricultural building and the plumbing and electrical for an agricultural building. There is in fact no agricultural building on the property AND they also just found out that the septic tank is under the master bedroom. Who can be held responsible if this was never disclosed during the sale? What steps should they take? The house is in Ramona, CA
