adding a foundation to an existing addition

Best way to get an idea as to what you will need is to bring in a mason for an estimate. Local requirements, soil, drainage, depth, all come into play. If you need this before you buy, you need to be very careful. A short sale is not for the inexperienced.

Bud gave good advice.
The basic steps are a proper footer will be poured and then underpin with concrete blocks. The final course of blocks should support the weight when done. They may be laid up to the joists or a space might be left to insert a single, treated 2x board and shims as needed. Don't forget the termite shield cap where the wood meets the block.

The old foundation and new foundation should be connected together with rebar. The footings and the foundation itself. My architect specked out 5/8" rebar, epoxied into each section of the wall. Two in the footing and 3 in the 36" poured concrete foundation wall.

There is nothing under the addition. No slab, just concrete blocks. The main house that it's attached to has a basement foundation of stone. I just want to level the addition and run some kind of foundation around perimeter to keep it level. Thanks for all of the info.

What climate zone are you in Cindy? Cold country will have some depth requirements to get below the required frost line. When you say it is currently supported on concrete blocks it sounds like a warm climate.
Do you intend to build this perimeter support yourself or hire a company?

Just wondering does the area where you are buying this home have building codes and inspections? I'm asking because it sounds like quite possibly that addition was built without any permits and inspections. If you start working on it and pull permits like you should you may run into a lot of trouble with the inspectors wanting additional work done and areas opened up for inspections. Just so you are warned.
