Build a Second Story
If you plan to add another story to your home, you’ll need to raise the structure and reinforce the foundation before construction begins. Reinforcing a foundation typically costs $7,000 to $35,000. Before embarking on reinforcing the foundation, it’s recommended to hire a structural engineer to inspect the foundation and confirm that it can hold additional weight.
Move Home
In addition to raising your home, moving requires transport permits, transport costs, and a new foundation. Transport permits typically cost $400 to $5,000, transporting the home itself ranges from $18,000 to $40,000 or more depending on home size and distance, and a new foundation at the final location typically costs $5,000 to $20,000.
Raise Above a Flood Zone
If you’re located in a flood zone, raising your home can reduce your insurance premiums and minimize the risk of water damage. Raise your home at least one foot above the Base Flood Elevation, which varies depending on your area.
Raising a house above a flood zone typically costs $20,000 to $80,000, including the base cost to raise the house and piers, columns, or pilings. Prices for these vary, with pier and beam systems ranging from $8,000 to $20,000, columns costing $13,000 to $24,000, and pilings costing $12,000 to $40,000.
Foundation Replacement
Raising a home to replace the foundation ranges from $20,000 to $100,000, with home size being the primary cost factor. Most foundation installations cost $4,000 to $15,000, while foundation repairs cost $2,200 to $8,000.
If you need structural reinforcements, your contractor may recommend add-ons like steel beam replacements costing $100 to $400 per square foot or basement waterproofing at $6 to $15 per square foot.
Build a Basement
Raising a home to build a basement is one of the most costly house-raising projects. In addition to the base cost of raising a house, you have to account for basement construction and finishing. An unfinished basement typically ranges from $25,000 to $70,000, while a finished basement costs $40,000 to $150,000.
