!!!! Can Underground Houses Meet Code in North Carolina?

Hey all, I am kind of obsessed with the underground house concept - however I have no idea if the earth foundation can meet code. From what I've seen any "basement" style will require a lot of expensive concrete. Des anyone have advice on how to go about doing this?

I would hunt down a building inspector in NC and have a sane conversation.   A good building inspector can save a great many headaches.  My approach is to view them as an  expert consultant rather than seeing them as the enemy.

Oh yes,  Welcome to Permies.

Mason, welcome to the forum!

I agree with John.

I assume you would be building in a rural area rather than in a city. Are you required to get a building permit in your area?

Then contact a code enforcement or building inspector for the county you would be building in unless you are building in the city.

Just here to say how much I love walking down into my walkout basement on a 95 degree day.  A small window AC unit (subbed it for a dehumidifier) easily keeps 900 sq ft at 68 degrees F.  The basement is build from hollow 12” block.  There is a small gap at the top of the block that I have been gradually filling with insulation, but I doubt the below grade part does much.  Good luck with your house, I’d love a 75% underground with ample windows!

Thanks so much! I'll try that first and see how it goes.

I have a basement in my house that was installed by Superior Walls. (https://superiorwallsnc.com/) no problem with code enforcement, solid precast panels that bolt together and floor is poured to join it all together, backfill and your in business... it stays cool in the summer and warm in the winter with no heating or cooling. They would be a good starting place for experts  and sources.

Unrestricted and no HOA is key. The actual task requires the know how once permissions are gained.
The follow up video that dave from vikingshelters he is marketing 10 moths ago: https://www.youtube.com/watch?v=F1i-qWU1pPY
and the original video done by Kirsten Dirksen (she is worth the hours you will burn on her channel) I can't put my finger on at moment. .but was a follow of the Quonset/ shotcrete one after over a decade of being. .  
I have been taking a lot of time with pre and early Holocene rounded pit structures and the like for cross reference purposes and would be glad to discuss when I can find time. The Prehistory Guys (youtube and podcast)have some nice Çatalhöyük and similar inspiration for viewing.
Material sciences that start with cob and progress through stone masonry and mortars seem to be so exciting to me in recent years and so much is actually cutting edge technology rediscovered from ancient times.
Babbling and hopefully some useful input -
Oh, cobb is not in and of itself applicable to the humidity and to some degree cold of NC. The methods of the different regions of world uses will help define path.

Mason, there are a variety of such homes, which style are you considering?
