In the current world, it seems like everyone is getting addicted to minimalist aesthetic living. Most of the minimalists emphasize simple living and reduced costs of living.
Besides this rising popularity, tiny houses account for less than 1% of the real estate transactions in the US. But they have recently attracted top reality shows such as Tiny House Nation and Tiny House Hunters and made a list in the viral pages such as the Cutest Tiny House in Every State. So what is regarded as a tiny house, and what would be the cost of establishing one?
For any house to be considered tiny, they must meet some basic guidelines by the American Tiny House Association. They must be no higher than 400 square feet, and they mustn’t be lower than 70 square feet. This is the first category of tiny houses. The second category is the houses that are between 400 sq. feet and 1,000 square feet. According to the 2009 statistics, the average size of an American house is 2,700 square feet.

Want to build a tiny house on a permanent foundation? Here is everything you need to know
When we picture a tiny house, we often figure the one on a trailer and with wheels. But the actual fact is that you can build a tiny house on a trailer or a permanent foundation. The tiny houses on trailers are for people that want to get around the city and move around without any restrictions. But as the tiny house movement gains popularity, some people want to build tiny houses on a permanent foundation, especially those in the rural areas where land is cheaply available.
Although the tiny houses on wheels are more popular, for some people, especially those with families, the tiny house on wheels is not very practical. Fortunately, there are two other alternatives that you can go with. You can build a tiny house on skids or a tiny house on a foundation.
Tiny House on Foundation
You can surely build a tiny house on a permanent concrete slab. Once the slab is ready, the next thing to do is get the foundation ready for the tiny house from main manufacturers in whatever size and shape you want and set it over the foundation.
Tiny house on skids/runners/piers
In case you don’t have permanent ownership of the land, you can go for the tiny hybrid house. However, you will only think of a tiny house pier foundation because it’s a semi-permanent solution. But if you go this way and you have plans of moving with your house later on, it will have to meet some standards to be allowed to be transported in a trailer. You also have to involve the building inspectors to ensure that the house is legal.
This post will mainly concentrate on the best foundations for tiny houses and tips and tricks of saving money on tiny house foundations.
Which foundation is right for your tiny house?
The right foundation for your tiny house will be influenced by a couple of factors besides the size and shape of the tiny house. You have to meet all the building standards and set regulations in your area; it will also depend on whether you permanently own the land or lease and few other factors. But in all cases, the foundation must be very strong. Depending on these factors, you will choose between semi-permanent and permanent foundations for your house. Choosing the right foundation for your house is the starting point for your precious and charming space. But how do you go about it?
The type of foundation
The first consideration is the perfect type of foundation for your tiny house. Each of them has its own pros and cons. To help you, we’ll discuss different types of foundations and their pros and cons, starting with the slab foundation.
This is one of the easiest and simple ways of getting a tiny house on foundations. It’s also very common and easy to try, especially for DIYers. It is simply a pad made by creating a wood frame known as a form and filling. In most cases, you will be required to lay in wire mesh or rebar to reinforce the pad. In the case of tiny houses, a 4-6 inch thick slab is perfect for you. But before getting to this stage, make sure you preplan and measure the slab and inquire about the measurements of the tiny house.
Concrete slab pros and cons
- Simple to build
- Very strong
- Relatively affordable
- Perfect for relatively bigger tiny houses
- Sturdy foundation
- It lacks flexibility
- Have preplan drains
Vented Crawlspace Foundation
This kind of foundation is formed by easily creating short walls that you will build the house on. You will be required to pour footers around the edge of the foundation, and the walls are built preferably between 2.3 feet. This is very important because you can run all the plumbing and the wires in the space. If your wires and the pipes run into problems, you can crawl under the space to fix them. The crawl spaces will equally have some vents in them that allow moisture out. Its main drawback is that the crawl spaces are dirty and typically dark.
Crawlspace foundation pros and cons
- Sturdy foundation
- Easy access to wires and plumbing
- Relatively expensive than slabs
- Requires steps to your house
Sealed Crawlspace Foundation
This is basically a mini basement foundation that works perfectly fine for tiny houses. The sealed space is very different from the crawlspace because there are no open spaces via vents. This will eliminate the molds. You can seal the space off and condition the space as part of the house. However, this kind of foundation is not preferred for tiny house foundation methods because there are chances of many issues such as bugs and moisture.
Sealed Crawlspaces foundation pros and cons
- Extra storage space
- It controls moisture and bugs
- Access to wire and pipes easily
- It’s strong and sturdy.
- It’s expensive
- You require HVAC
Tiny House Basement Foundation
For tiny house enthusiasts that don’t care about the expenses, this foundation is the best. It’s one of the most expensive foundations that you can get around mainly because you will have to dig to the earth, which needs engineering. The extra space that is gained will work as a basement for extra storage or additional living. But before you try this type of foundation, you have to check with the local building codes and make sure you meet all the standards. It would be highly prudent if you also got a contractor that properly understands insulations, seals and drains. Building finishes are also very important to reduce flooding in bad weather.
Basement foundation pros and cons
- Extra storage space
- You can easily access wires and plumbing
- Low-cost square footage
- It’s the most expensive type of foundation
- You require permits
- It requires engineering
Tiny house piers or tubes Foundations
This type of foundation is a footing placed in a grid pattern into the ground with a bracket on top. The bracket connects directly to the underframe of the house. The piers are simply rows of poles that are laid out in the grid. This is simply done with the use of larger timbers running between them. This kind of foundation is perfectly suitable for sloped lots.
Piers Foundation Pros and cons
- They are very affordable
- It’s very easy for a DIYer
- Access to plumbing and wires
- Not allowed in some states
- Requires permits
- It’s not a permanent solution
Skids or runners Tiny House Foundation
Lastly, let’s discuss one of the most popular tiny house foundation options that serve as a semi-permanent solution. This foundation is simply a collection of large timbers placed on the bottom of the house and works as runners that can drag the house. The skids are usually made of lumber and steel.
Skid foundation pros and cons
- Mobile in a pinch
- Low cost
- Semi-permanent and movable
- Simple materials
- String and sturdy
- Can rot away
- Hard to access under the house
Is Building a Tiny House on Foundation actually worth it?
Besides the mobility benefits, which is why tiny houses are built on wheels, there are several benefits of building a tiny house on a permanent or semi-permanent foundation. So can you put a tiny house on a foundation? Is it really worth it?
Before answering this question, you should understand all the costs and procedures of building the foundation. First of all, you will require local permitting and potential placement restrictions. Every state has some building and zoning codes that dictate how the houses should be built. Consequently, you need to make sure you have followed all the guidelines.
Constructing a tiny house on wheels is the next big thing because it has many economic and practical benefits. So, can you put a tiny home on foundation and is it really worth it? Yes, a tiny house on a foundation is safe irrespective of the type of foundation because the house will be firmly rooted in the ground. Another great reason it’s worth it is that financing a tiny house on a foundation is more the same as financing a traditional house. This means that if you have a good credit score, you can be financed easily.
The cost of building a Tiny House Foundation
You are probably wondering how much it does cost to build a foundation for a tiny house. One of the highest expenses when building any house is the foundation. The cost will, however, vary depending on the kind of foundation that you are going for. A simple slab foundation can cost up to $2,000, including the materials and the labor. But compared to building a tiny house on a trailer, this is relatively cheaper. The trailers can cost between $3,000 and $6,000.
Another area where you can incur significantly is zoning and permitting. You must ensure that you are complying with all the zoning ordinance regulations, which are additional costs. With a permanent foundation, especially the basement foundation for a tiny house, you will get permits and at the same time be required to pay for the additional costs of engineering and to dig the ground.
The building permits will equally vary depending on the type of foundation and the location. In most areas in the US, you are looking at an average of $1,200 for the permits. Besides the cost of the foundation and the permits, you will equally need a sewer and a waterline connection which is always expensive in some parts of the country. Most cities will charge as high as $11,580 for the connection.
Luck is with the people outside the city in rural locations because you can get a traditional utility hook-up or drill a well and install a temporary septic system. You might also choose an off-grid option such as a solar panel and compost toilet because these are more affordable and can stay longer. The other important thing about the off-grid options is that you don’t have an additional bill to pay after the initial cost.
Compared to the tiny houses on trailers, you might save money on the trailer, but you require a lot more to comply with building the foundation. Besides the information shared here, the cost of building the foundation will vary depending on the type of the foundation, the size and the permits.
Building a house on the foundation is worth it, but you will have to pay more depending on where you live. The cost of the foundation can vary from $4-$25 per square foot, depending on where you are in real-time. The amount that you will pay will equally depend on how shallow and how deep the design is. The Monolithic concrete slab can cost up to $14 per square foot.
Planning is the initial step in any project, which addresses some things such as the local building code and pulling the building permits. This means that the planning stage will equally contribute significantly to the cost of the foundation. Getting the right documents to start building and paying someone to design the foundation for you are major costs.
Safety is another significant consideration. You must make sure that the construction is safe. This means that you will have to carry out soil tests, oil reports, and few other considerations. The builder will equally need to know the soil’s compaction and frost line depth to determine what is needed for safe construction. This can cost anywhere between $800-$1,000 if you need the seismic and flood reports.
In some areas, you will need to pay for the inspection of your area to make sure that the structure is sound. The cost of paying inspection is around $500. You cannot skip this essential part, and the construction shall not proceed until the inspector signs off on the foundation.
A large share of the building cost will go into materials which include the cost of concrete. This will also be determined by the different types of foundation that you need to be installed. You might need few bags of concrete to thousands of concrete and concrete blocks installed to support the house. The foundation will also require labor reinforcement and molding, which equally adds to the cost. Moving on, foundation insulation will significantly impact the cost. You can end up paying up to $2,000 depending on the insulation materials and the foundation.
Drainage is very important in any type of foundation for your tiny house. It doesn’t matter whether you install a full basement foundation or a slab foundation, moisture build-up can cause significant water damage and can lead to a lot of risks. Some simple drainage systems such as a sump pump and grading can cost up to $5,000, depending on the size of the foundation.
Heating is one of the biggest considerations in a tiny house. For that reason, you might have to consider how the home is heated and how the heating system will affect the foundation. Planning and installing radiant heat can also cost you significantly, depending on the foundation type. Additional project costs may also apply to the slab foundations. If you have hot water heating, you will equally need to set the lines on the slab.
How to save money with Tiny House Foundation installation
You previously asked yourself many questions about the tiny houses and why you should put your tiny house on foundations. After giving you insights about the cost of installing different types of foundations and the factors that significantly impact the cost of Tiny House foundations. We now have to let you digest some tips on how to save money on Tiny House foundations.
Saving money with concrete foundations
One of the notable methods of saving money with a concrete slab is to go with the monolithic slab instead of the stem wall. This can save you up to $1 per square foot. You can also skip a vapor barrier because most slabs never have a fatal problem with moisture, especially if you live in a dry climate. This might save you up to $1,000 on vapor barrier installations.
Saving money on Pier and Beam Foundation
The cost of installing Pier and beam foundation will significantly increase as you add more piers. Consequently, you can save money by just going with a perfectly rectangular home. You also have to make sure that there are no bump-outs because they can significantly reduce the number of pairs needed, bringing the overall cost down.
Saving money on CrawSpace Foundation
The most effective method of saving money with the crawl space foundation is to avoid using a vapor barrier. As I’ve already stated, most concrete doesn’t have a fatal risk with moisture. However, this is not recommended unless you live in an arid climate and are not prone to floods. This means that you can combat minor water issues with proper drainage. If otherwise, you might not save money, and you can end up paying more money for the repairs.
Saving money on Full Basement
As I’ve already stated, the full Basement Foundations are the most expensive. Thus, this is where you really need to be more creative and save a significant amount of money. The first method is to avoid the vapor barrier because it can save you a few thousand dollars on installation. Additionally, you can save more money by simply leaving the Basement Foundation unfinished because it can save you more than half of the money.
