Size of the Home
One of the most significant cost factors is the size of your home. The larger it is, the more it weighs, and the more complicated the process of raising it or transporting it will be. Most companies that do this kind of work will be able to give you a cost estimate based on the square footage of your home, but every price will be different based on other details, such as the condition of the house and foundation. The best way to get an accurate quote for your particular project is to consult and hire a foundation contractor.
Labor
The cost of labor is difficult to nail down and can vary depending on the complexity of your project and the wage expected in your area.
Condition and Age of House
Older homes are going to need extra care and reinforcement during the process. This is because of the structure's age and because they typically have heavier materials. This will take more equipment and time, and contractors may need to move the house at a slower pace if it is older and more vulnerable.
Elevation
A house may need to be raised a few inches (or up to 12 feet) from its foundation. The higher the home is raised, the more time and equipment the process will require. Costs range from $10 per square foot for 1 foot of elevation to as much as $35 per square foot for a 12-foot lift.
Plumbing and Electrical
Licensed electricians charge $50 to $100 per hour, while plumbers charge $45 to $200 per hour. These utilities will be disconnected for the process and then reconnected upon completion, which requires expertise and time.
Patch and Paint
When the home is raised, inevitably, there will be some cracking in the drywall at the interior of the house and in the exterior finish as well, especially around doors and windows. “One should factor in additional cost of patching and paint,” said Ezra Laniado, Expert Contributor and Founder of Landmark Construction & Development Group. “This cost will vary depending on how much cracking occurs and if the paint color and sheen can be matched well enough.”
Excavation and Grading
Excavation costs $1,450 to $5,000. The demands will vary from one house to another, and your cost could grow if special equipment and extra time are needed.
Condition of Foundation
The average cost for foundation repairs is about $4,800. Repairs or accommodations that need to be made to stabilize the home—in the event of cracking, leaking, or setting—can add significant costs.
Building Permits
Building permits usually cost $1,200 to $2,000. The permit for this project can be sizable, especially compared to the cost of a regular building permit.
New Stairs
Access to exterior doors will change if the house is moved or permanently raised. This may require building new stairs to reach the exterior doors. Costs for replacing concrete steps range from $900 to $5,000 for each of the home’s entryways.
Structural Engineer
Hiring a structural engineer costs $800 to $3,000 on average. Having your home inspected for structural integrity before and after raising is extremely important and should not be skipped.
Architect
Architects charge $125 to $250 per hour. An architect may be the best investment you make for this project. They have the knowledge and experience to ensure that the money you spend doesn't go to waste. They can help you obtain the right permits, meet zoning requirements, and achieve the optimal design.
Insurance
Expect insurance expenses—which should cover at least $100,000 to $200,000—to be factored into your cost. Talk to your insurance agent to ensure you are adequately covered. Request insurance verification from your foundation pro as well.
"If you are moving your house from one site to another and you have a mortgage on it, you have an obligation to inform the bank holding your note as they have a financial stake in the property," says Cati O'Keefe, Expert Home Building & Sustainability Contributor.
Landscape and Cleanup
Trees and landscaping can inhibit access for laborers. Therefore, you need to include land-clearing or removal, as well as replanting or rebuilding your landscape costs, when budgeting for the project. Contractors require a lot of space for their equipment and for excavating around the work area.
As such, you may wish to remove trees and landscaping in order to replant them afterward, or you may choose to scrap your landscaping and start anew after the lift. Removing a single tree can cost $700, while rebuilding the landscape could cost $1,400 to $5,500.
Additional Considerations
Other items that could affect the total cost to raise a house include the possible need to move, raise, or construct new utility feeds like water, gas, and electrical service connections. Grants may be available in some areas to relieve some of the cost burden on homeowners in known flood areas or disaster relief areas.
