How Much Does A Permanent Foundation For A Mobile Home Cost?

Last Updated on March 21, 2021 by

An excellent permanent foundation for a mobile home involves blocking walls and concrete footings below them. The cost of a permanent foundation is calculated per meter with an average cost of 100 to 120 dollars. However, this cost is dependent on some factors, such as the type of permanent foundation to be laid and it may vary from state to state but not too far from the above range. 

What Is The Average Cost Of A Permanent Foundation?

The cost of a permanent foundation is typically calculated as per one meter. It is affected by factors such as;-  the type of subsoil and the type of permanent foundation installed since some are more expensive. Another factor that affects the cost of the permanent foundation is the size of a mobile home to be installed.

 Larger mobile homes are more expensive as they require more materials compared to smaller ones. Generally, a permanent foundation for a mobile home is likely to cost about 100 – 120 dollars per meter. However, the total cost of laying a permanent foundation is dependent on the size of one’s structure, with all the other factors held constant.

What Are The Types Of Permanent Foundations For A Mobile Home?

Permanent foundations are fixed immediately after being built and they provide stick-built support for the mobile home. There are two types of permanent foundations, namely; – basement foundations and pit foundations.

Basement Foundations

Basement foundations provide both structural support and additional living space to the mobile home. The advantage of this type of permanent foundation is that it can easily integrate into one’s housing plans, especially with the added extra living space created. It can also help a real estate with financing options. Basement foundations are also known to have good earthquake resistance. 

There are some disadvantages associated with the permanent basement foundation, such as the tendency to get flooded in cases of heavy downpours. They are also difficult to construct to meet the building codes of which is a must. Basement foundations are the most expensive foundations with a very long and complex installation process.

Pit Permanent Foundations

They are not so different from the basement foundation. The only significant difference is that with a pit foundation, a pit is dug out of the soil, forming a crawl space that is not livable. Their advantage is that they also give permanent stick and firm grip to the home. They also allow storage of extra facilities in the dug pit, which creates extra space even though it is not livable. Pit foundations also tend to be cheaper hence offering better financing options.

Pit foundations are at a greater risk of flooding. Their construction process is also long and challenging, making them costly as well.

What Are The Other Types Of Mobile Home Foundations?

Other than the two types of permanent foundations, there are types used for both mobile and manufactured homes. They include; 

Pier And Beam Foundation

It is the most commonly used foundation for mobile homes. It involves driving anchors on the ground to hold the mobile home down, protecting it from strong wind forces. The anchors are first driven to the ground, and steel straps get attached to them. The straps act as a connection to the main beam on the steel frame of one’s home. Outriggers are then welded to the steel beams for extra support and strength.

The advantage of pier and beam foundations is that they are very cheap and easily affordable. They take less time to install than the permanent foundations. Additionally, they can be used in extreme weather conditions such as floods, heavily frosted and seismic areas. Their ability to withstand such harsh conditions and acting as wind zone resistors makes them preferable over other foundation types.

Crawl Spaces Foundation

 Crawl space foundations designed for mobile homes are made of the excavated floor. They are built with poured concrete footers that run down to the ground for anchorage. The mobile home’s frame rests on a wall supported by piers strategically placed to offer support. These points are customized differently in each home.

Crawl space foundation installation price ranges between the permanent foundation and the pier and beam foundation, meaning it is relatively fair. Time taken to install them is almost the same as pier and beam. They also have high wind resistance ability, seismic resistance from their strong stability and can withstand frosty situations. Their only disadvantage is they are prone to floods hence cannot be used in areas that experience heavy downpours.

Slab Foundations

A slab in mobile houses acts as more of a support system than a floor to the home. In this case, a slab rests on top of the ground with anchors held on concrete. It is insulated around its perimeter, keeping the ground warmer which generates warmth to the mobile home.

Slab foundations are among the cheapest and most affordable mobile home foundations. They require very little time for their installation and are seismic compatible. They can be used in flood hazard areas and frosty environments since they are insulated and are not easily affected.  However, they are not suitable for sloping areas, and one has to verify wind zone requirements for the site before installation. They are not commonly used like the crawl space and pier and beam foundations.

What Things Should One Consider When Preparing Land For A Mobile Home?

The best advantage of a mobile home is that they allow one to establish it on vacant land more quickly than the other conventional site-built constructions. However, they have a similarity in that land preparation before installation and setup is very crucial. The following are some essential tips to consider to ensure a perfect installation of the mobile home.

Requesting For A Land Survey

It is an important step for any site work preparation, which involves site inspection. You must have updated information instead of relying on an old survey with vague descriptions and incorrect information with outdated landmarks. A current site inspection will provide clear information on any discrepancies between both survey inspections. It will also indicate whether one’s land status is suitable for a mobile home or not.

Application For Necessary Permits

Some permits are required when installing a mobile home. They include transport permits, building permits, occupancy permits, and in other cases, a utility connection permit. One can visit government sites to learn more about mobile housing and get more details on permits needed to transport and install the home. For instance, some states require one to submit permit applications at least six weeks before the scheduled transportation and installation of the mobile home.

Selecting The Location Of One’s Home

Before the installation, one should have clear markings of boundary lines of one’s property to establish a specific location of the mobile home. It helps one make decisions such as available room for the driveway and the available outdoor space after installation. Planning the site’s access before installation and setup are very important. One can even consider removing any unwanted vegetation such as shrubs and trees.

Installing The Foundation In Advance

 If one is considering a permanent foundation, it should be done early in advance as it involves pouring thick concrete that requires time to cure and dry fully. How first the concrete will cure and dry depends on the prevailing weather conditions of a place. To avoid inconveniences and delays in installation, one should consult with the builder to ensure the foundation is perfectly ready before the mobile home is installed.

Setting Up The Needed Utilities

 Bringing in utilities is another important activity to be carried out before the actual mobile home installation. The best thing is to communicate with mobile home contractors and dealers to ensure all utility services are readily available by completing the installation.

What Should One Consider Before Putting Their Mobile Home On A Permanent Foundation?

One should take their time to ensure the mobile home and the foundation fit their lifestyle and are perfect. The first thing to consider is the surrounding area and social amenities available as they all influence the value of the mobile home. Another consideration is the building permit and other licenses applicable. Application of such permits takes time before they are processed and obtained but are a must in the construction of permanent foundations. Materials used in the construction of a permanent foundation are the most costly. For this reason, one should consider hiring credible and reliable workers to ensure that the materials are sparingly used without wastage.


Mobile home permanent foundations are quite expensive compared to semi-permanent foundations. The reason is mostly because of the materials used and the labor required making them costlier.

 Other foundations such as slab foundation and pier beam are relatively cheap and are mostly considered to withstand harsh weather conditions. Permanent foundations are also prone to floods hence are not preferably used in areas that are likely to experience heavy downpours.
