Stilt homes often face stricter scrutiny due to their unique design. Building codes may specify minimum heights for stilts, required materials, and structural reinforcement methods. Wind load calculations are crucial in hurricane-prone regions.
Fire safety is another key consideration. Codes may require specific egress options, fire-resistant materials, or sprinkler systems for elevated homes. Accessibility requirements, such as ramps or elevators, may apply depending on the building’s use and occupancy.
Consult with local building officials early in the planning process. Their guidance can help avoid costly design changes and ensure a smoother approval process.
Construction Elements
Building a double wide on stilts requires careful consideration of key structural components. The foundation and support system are critical for ensuring stability and safety in elevated designs.
Piers and Pilings
Piers and pilings form the backbone of a stilt-supported double wide. Piers are vertical support structures that transfer the load from the home to the ground. They can be made of concrete, steel, or timber. Pilings are long, slender columns driven deep into the soil to provide additional stability. The number and spacing of piers and pilings depend on soil conditions, load requirements, and local building codes. Engineers typically determine the optimal layout to ensure even weight distribution and minimize settling.
Secure the Structure with Concrete Pilings
Concrete pilings offer superior durability and load-bearing capacity for double wides on stilts. These reinforced columns are cast in place or precast and driven into the ground. The depth of concrete pilings varies based on soil composition and load requirements. Reinforcing steel bars within the pilings enhance their strength and resistance to lateral forces. Concrete pilings are connected to the home’s frame using specialized brackets or plates. This connection system allows for slight movement while maintaining structural integrity during high winds or seismic events.
