In which states can basem*nts be found? There are important structural reasons to build homes with and without basem*nts, and here’s why.
Do you find it strange when a house does or doesn’t have a basem*nt? As someone living in the United States’ Tornado Alley, I have come to expect a basem*nt in every house I visit or move into. The fact that there are some places where basem*nts aren’t common was surprising!
Where are they? Where aren’t they? And why is there such a difference between certain locations?
On average, in the United States, basem*nts are most commonly found in the Midwest. This includes states such as Nebraska, Kansas, Oklahoma, Iowa, Missouri. Expect to find basem*nts in areas that are susceptible to tornadoes, for the purpose of shelter, or a frost line, in which case the house foundation is required below freezing depth.
There are so many regulations and restrictions when it comes to the way houses are built, and differences in their requirements depending on where they are. It can be pretty confusing if you don’t know what you’re getting into, especially when moving from one area of the US to another.
That is why in this article I will explain everything from where basem*nts are, where they aren’t, why they’re important, and how in certain areas they can do more harm than good.

Which States Are Basem*nts Allowed In?
Of the 50 states in the US, only in 7 are basem*nts commonly found. These states are known as being a part of ‘Tornado Alley’. That doesn’t mean there aren’t basem*nts in any of the other 43, only that you’re less likely to find them there.
There actually isn’t a state where basem*nts aren’t allowed, just not preferred. And for good reason, trust me.
The 7 states that house the majority of the United States’ basem*nts can be found in the Midwest – no pun intended!
- North Dakota
- South Dakota
- Iowa
- Nebraska
- Missouri
- Kansas
Although they all reside in ‘Tornado Alley’, the threat of thrashing winds isn’t the only cause for concern. Do you know what a frost line is? Before this article, I had no idea how important it is.
frost line [frawst-lahyn]
noun
the maximum depth at which soil is frozen.
Definition according to Dictionary.com.
The frost line varies with different locations and is another factor that determines the need for a basem*nt. Not for shelter, but to prevent frost heaving from damaging the foundation when groundwater in soil freezes and, in doing so, expands upwards. This will push your house off balance, potentially cracking walls, ceilings, and pipes to a point to warrant danger.
Basem*nts keep this from happening by acting as supports at least two feet below the frost line. Because of how the frost line fluctuates with location, supporting basem*nts can be found in many states other than the common 7 listed above.
On the other hand, if the frost line is closer to the surface, it becomes harder to find a house with a basem*nt. This is thanks to high expenses for construction, as well as flooding and rock that is too hard to dig into. Houses in these areas are less likely to need support or protection from freezing pipes and cracking walls.

Why Are Basem*nts More Common In The North?
Why do some areas of the US have basem*nts? The North, in particular.
As you may know, the further North you travel, the colder the temperature becomes. Due to cooler weather and the dropping position of the frost line, basem*nts are needed to prevent heaving and frozen or cracked pipes.
In states such as Texas, the weather hardly gets cold enough to harm their pipes, and as such they can be found simply a handful of feet below the surface. The frost line rises closer to the surface as you near the equator, the opposite of nearing the poles, and so the need for support lessens.
I don’t know about you, but as someone in a colder state I was surprised to find this out. It can get so cold that even our basem*nts don’t protect our pipes from freezing! Heat tape is a lifesaver!
States Where Basem*nts Are Common:
Are Basem*nts Common In California?
No, basem*nts are not common in the state of California. This not only has to do with warmer temperatures, but it was cheaper to build homes on a basic foundation rather than over a basem*nt.
However, this has been changing through the years. We have come to realize that basem*nts are not only a convenient and nearby place to take shelter in the event of a tornado but during an earthquake, too. They may not be common in the majority of homes in this Western state but they are making appearances in newer buildings.
Are Basem*nts Common In Georgia?
This is a state where basem*nts really aren’t necessary. With Georgia having a warmer climate and one of the highest frost lines, only five inches from the surface according to WordPopulationReview.com, there isn’t much need for a basem*nt other than storage purposes.
However, paying for a basem*nt to be built on top of other construction fees may be too steep in some people’s eyes, and not worth the risk of flooding from the water table or working around the type of soil found there.
Are Basem*nts Common In Texas?
You aren’t likely to find many houses or buildings with basem*nts when in this state.
Why aren’t basem*nts common in Texas? The high water table causes anything underground to be prone to flooding. It costs close to a fortune to get around this with the use of pumps and pipes. Most people don’t think it’s worth it just for a bit of extra storage.
The bedrock is also closer to the surface than in other states. While the soil above bedrock is unconsolidated rock, bedrock itself is consolidated, meaning it is very solid and very tough. This makes it difficult to dig down and install a basem*nt – extremely difficult. Just like the previous roadblock to basem*nts, this will cost you a lot of time and money to get past.
Are Basem*nts Common In Colorado?
It’s true that there are some parts of Colorado where up to 50 to 60 percent of homes have basem*nts. The frost line may not be as much of an issue here as in other Northern states, but because it’s 44 inches below the surface, basem*nts are still needed to support homes and other buildings.
With temperatures dropping as low as 6°, the groundwater in soil will freeze and expand to push the items around it. Basem*nts are a strong, sturdy way to ensure that this doesn’t affect the leveling of a house. Once one part of the structure is displaced, the entire house is at risk.
Are Basem*nts Common In Kentucky?
The need for basem*nts in Kentucky tends to vary depending on location. Some consider it a Southern state, others a Northern state, due to the fact that it sits a bit in the middle of the US. At 15 inches, there are many buildings that do, indeed, have basem*nts.
Check it out here on the frost line map at WorldPopulationReview.com and decide for yourself whether it’s a Northern state or Southern state!
Are Basem*nts Common In Oklahoma?
Due to the high water table, which moistens soil and can cause flooding, basem*nts are not common in Oklahoma. Because the frost line is only 20 inches below the surface, there is no expansive need for supports or to keep pipes from freezing the way they do in Northern states.
That’s not to say you won’t find a basem*nt or cellar here and there. They simply won’t be a common occurrence.
Are Basem*nts Common In Oregon?
When construction first started in Oregon, the consequences of basem*nts or underground construction may not have been widely known. Now that we are aware, you will not find newer houses with basem*nts.
Not only is support not required, with the frost line being 18 inches below the surface, but flooding is a genuine concern in Oregon. As with many other West Coast states, basem*nts here are more subject to flooding from the ocean and the high water table.
It’s for the best that basem*nts are skipped during construction here!
Are Basem*nts Common In The UK?
It would be silly to assume that the US is the only place you can find basem*nts. Of course there are other places, but how common are they?
In the UK, for instance, you will find basem*nts. However, they aren’t the typical basem*nt you think of when you live in the United States, spacious and at times finished to become an area to casually occupy. Here, they tend to be smaller and are used for storage, like a cellar for wine or other goods.
Those cellars used to be used for coal but as time progressed, less and less homes were constructed with a basem*nt, or cellar, beneath them. Because of the cost of digging down to an acceptable depth and waterproofing, the tradition of coal cellars was pushed aside. Those that you find now are more than likely very old.
Are Basem*nts Common In Germany?
Yes. Unlike in the UK, basem*nts are very common. Not unlike the UK, they tend to be smaller in size but are typically used for storage in housing blocks
Don’t know what that is? Well, a housing block is basically just an apartment building. I know, I thought it was something else, too! Of course, apartment rooms are small and don’t have much space for storage, especially when you’re moving out of a bigger house.
Instead of having to rent out a storage unit ten miles away, the renting lease generally includes storage space in the basem*nt of the building. These can be separated by walls or chain-link fencing, locked for the residents’ security.
