I am looking at buying a home that has a very large basement. The first floor is about 5.5 feet off the ground and the basement is about half a foot lower than the grand level. The basement is about 6 feet tell and is the whole floor plan size with a large wide door on the outside. Its about 1000sf. The house has no garage so this would halt to be my shop. I could easily get a dirt bike in and out of there. My caponord would go in easy but getting i out would require running it and walking next to the bike. There is a small 3-4 in drop at the door. Only half of the basement has cement so I plan to dig the other part down 1-2 feet. I'm 6,2 so I need a bit more height to stand up in about 2/3 of it. 1/3 is already dug down. My main question is what are the risks of having you shop under the house? The lower part has 4 or 5 windows plus the big door so I could easily vent the room. Should I not store any gas inside? I could prob get a small tough shed for the outside next to the house. There is slab there but in the city of sac it can't be more than 120sf or you have to get a permit. Anyways Tell me what the risks of this are that will burn or blow up my house.
