I'm building an attached two bay garage. Do I need to dig a footer and pour a foundation for this garage? Can I just pour a cement slab to build the garage on?

IM adding an attached two car garage too -- to a house with a basement. The existing garage has a block foundation, at least four cement blocks deep.

Im trying to find out if I can just dig a trench -- eight inches wide, and four feet deep - and pour a straight wall down in the ground, sticking out about a six inches. The drawings I see usually have a 16 inch wide base, below frost line, with eight inch blocks on top of that. Id like to avoid the work and expense of that 16 inch base, and the the excavating that would take. Do you, or anyone, know if I can just pour the wall as described, and forget the base?

anyone who's got such limited knowledge needs pro help,,, short answer's YES !

good luck

i'd wager there's a conc fnd UNDER those block walls,,,

if you've got frost to that depth, you'd need a footer 1st,,, THEN pour the wall on top of it,,, but the bldg code'll have your rqmts clearly outlined,,, short answer's 'NO, you cannot!'

then again, its YOUR garage !,,, but if you ever want to sell the property, you may open yourself to 'troubles'
