1 Adding a basement to an existing house can cost $30,000-$70,000 or more, depending on the size of the existing crawlspace or half-basement or if the house is on a slab foundation, and how much of the work is do-it-yourself and how much is done by contractors. Having a prefabricated safe room (a welded steel box, a steel skeleton with steel planks or a prefabricated unit that is bolted together on site) installed in a basement can cost $3,000-$20,000 or more, depending on materials and size.
Cost to lift house and put in new foundation. I had an engineer out to look at our sloping house. He said it's likely we'd need a new foundation, and the cost would be around 100K. I was thinking maybe 50K. I'm thinking house lifting and excavation would be 15K and basement footings and walls, with no floor, would be 25K-30K. Misc. permits and stuff would be another 5K-10K.
