Learn what foundation types are options for modular housing. Having a strong modular home foundation is key in keeping the home durable for a lifetime. There are different types of modular home foundations that a home can be placed on, with varying materials, but what foundation your home can be placed on may be based on local building codes.
Learn how choosing the right foundation for modular and prefab homes ensures stability and longevity while meeting building code requirements. Modular home foundations are the structural systems upon which the prefabricated sections of a modular home are placed and secured. Unlike mobile homes, which often use skirting or piers alone, modular homes are typically designed to sit on permanent, code-compliant foundations such as crawlspaces, basements, or slabs.
A mobile home foundation is the support system that sits between your manufactured home and the ground. Unlike traditional site-built homes where the foundation is integrated into the construction from day one, manufactured homes are built in a factory and then transported to your lot. Modular homes need space under the home for electrical, heating and cooling, and plumbing connections, and cannot be placed on a slab foundation because the home needs to have a way to fasten to the foundation.
Your home's foundation is a critical component that determines its stability, strength, and durability now and in the future. The foundation requirements and costs for manufactured and modular homes differ depending on the home type and the foundation style used. Foundation costs vary a lot depending on type, materials, and prep work.
For most modular homes, slab-on-grade is the cheapest, both to build and maintain. Crawlspaces cost a bit more but make repairs easier, which can save money down the road. Basements are the priciest but add valuable living or storage space, possibly boosting resale value.
The Guide to Foundation and Support Systems for Manufactured Homes contains information for many audiences but it is written with one goal in mind: to help those in the industry responsible for selecting, designing, and installing foundations recognize the available options and make well.
