Whats the difference between different types of mobilehome foundations?
There are a number of different foundations available for mobilehomes. All of them fall into the categories of either a “perimeter type” or a “pier and pad type”. The perimeter type is typically concrete or concrete block on a continuous footing and reinforced with steel rebar. The mobilehome is securely attached to the perimeter wall. This type of foundation is generally used only when installing a new home. Once the home is already installed it becomes very difficult and expensive to install a perimeter type foundation. Pier and pad type foundations are installed under the chassis of the mobilehome and are much less difficult and less expensive than the perimeter type. They work in conjunction with, but should not be confused with, the “Support System” that all mobilehomes must have. A Support System is made up of steel piers on treated wood pads spaced between 5 and 8 feet apart under each chassis beam (in some parts of the country, concrete block is used instead of steel piers).
