The Complete Guide to Lifting a House and Building Underneath

Lifting a house and creating additional living space underneath can be a transformative project, providing numerous benefits including added stability, protection from natural disasters, and increased property value. However, it’s essential to understand the costs and considerations involved before embarking on such a venture. In this comprehensive guide, we’ll break down the various factors that contribute to the overall expense and steps involved in lifting a house and building underneath.

Assessing the Need:

Before delving into the costs, it’s crucial to evaluate whether your house requires lifting and building underneath. This is typically necessary in cases of unstable soil, flood-prone areas, or when the existing foundation is compromised. The process involves excavating the area beneath the house, establishing a new foundation, and securing the house in its elevated position. Costs may vary based on the size of the house, foundation type, and soil conditions.

Estimating House Lifting Costs:

The average cost for lifting a house and building underneath ranges from $25,000 to $50,000. However, this figure is subject to change based on factors like house size, foundation type, and soil stability. Larger houses or those on unstable soil may incur higher expenses. It’s important to note that not all houses are suitable for this process; structural integrity and space for excavation are crucial considerations.

Hiring Professional Contractors:

Lifting a house is a complex undertaking that demands the expertise of professional contractors. Their experience ensures that the process is carried out safely and efficiently. Additionally, they can advise on the appropriate foundation type for your specific situation. While costs may vary, the average expense for house lifting services falls within the range of $10,000 to $15,000.

Budgeting for Equipment and Permits:

House lifting requires specialized equipment, such as cranes, which can be rented. This rental cost, along with necessary permits, can add approximately $10,000 to $50,000 to the overall expenses. Permits, in particular, are crucial to ensure compliance with local regulations and safety standards.

Foundation and Structural Reinforcement Costs:

Building a new foundation and reinforcing the structure of the house is a critical step in the process. Costs for this phase generally range from $5,000 to $15,000, depending on factors like house size, foundation depth, and material choices. It’s advisable to consult with a contractor for an accurate estimate tailored to your specific circumstances.

Excavation and Building Underneath:

Excavation involves digging a hole large enough to accommodate the lifted house. This cost varies based on house size, soil conditions, and terrain, and can range from $15,000 to $20,000. Building the new foundation, which includes pouring concrete and installing framing and roofing, is another essential step with costs that depend on various factors.

Plumbing, Electrical, and HVAC Installation:

After the house is lifted and a new foundation is established, the next step is to address plumbing, electrical, and HVAC installation. This phase can add an additional $10,000 to $20,000 to the total project cost, depending on the complexity and scope of the work required.

Finishing and Renovation Costs:

The final step involves finishing and renovating the space underneath the house. Costs for this phase vary widely based on the size and condition of the space. On average, homeowners can expect to spend around $10,000. This may include installing floors, walls, ceilings, and any other desired amenities.

Conclusion:

Lifting a house and building underneath is a significant undertaking that requires careful planning and budgeting. By considering the various factors outlined in this guide, homeowners can make informed decisions about whether this transformative project is the right choice for their specific circumstances. Remember to consult with experienced professionals and obtain accurate estimates before embarking on this endeavor.
