"We had Mark remodel our second bathroom a few months ago. The remodel turned out exactly as we planned, Mark did an excellent job giving us a really beautiful space. He finished slightly ahead of schedule and he left the project neat and clean at the end of each day. We have an upcoming project we want Mark to do for us in 2027!"

"This group of workers are family and work together. They are very efficient, on time and do really high quality work. They built a barn for me and did it in a very short period of time with excellent outcomes. Everything was square and fit together perfectly. I was very impressed and happy that I had them do the job for me."

Barndominium Builders FAQs, answered by experts

This answer varies based on where you are, but most states require that all homes are greater than 320 square feet. Remember that four walls are not the only requirements—windows, closet space, minimal ceiling heights, and indoor air quality are also factors. Each state and municipality differs, though, and as some don’t consider tiny homes permanent shelters, you’ll need to check to ensure you aren’t violating any local or state laws with your build.

It is recommended that you check with your local building official on barn building requirements and rules, since size restrictions vary greatly from region to region based on what your property is zoned for. Some cities limit barn construction depending on if your property is residential or commercial. The three main factors your building commission will evaluate are:

  • Height and lot coverage: How tall your barn is and how much of your total property it occupies

  • Setback: Distance between barn and property line

  • Easement: Legal right for another owner to access another’s property

The foundation for a pole barn should be at least 36 inches thick to ensure that the piers won’t shift from frost heave.

Concrete blocks are the cheapest way to base a shed. However, the space in between allows critters to go under, burrow, and even damage your shed’s frame. For a more pest-proof option, consider building a shed base with gravel or paver stones. Both options are fairly affordable and easy enough for a DIY project. For gravel, you can build a wooden frame to contain the loose material.

Complex plumbing is tricky and expensive in an off-the-ground dwelling like this. By considering options like composting toilets, rainwater collection, and gray-water sinks, you save money and help the environment.
