When purchasing a home, the seller or property owners may be required by law to disclose whether the property is affected by mine subsidence. If a disclosure is not available, you may be able to use EPA maps or state search options to identify potential subsidence. Some states even have online tools where you can put in your exact location and find out if your property is affected. Or, if you live in an area prone to mine subsidence, you may want to look for signs of the problem. In many cases, the first signs of damage could be cracks in the foundation and sagging walls. Other common signs are sinkholes, cracks in the ground, uneven floors, doors and windows, and shifting walls. Damage to the electrical system, including short circuits, could be another sign.
