This is a new home inspection. Home is built on a slope, and the soil is very sandy. The column footing in the first photo is not deep enough and is already starting to be undermined at the downhill side. In my area foundation footings must be 18" below grade, but I don’t think that applies to post footings in the crawlspace. Anyone know if there are any other requirements that dictate minimum post footing depth?
Also, the home has a post that bears on the exposed exterior foundation footing in the crawlspace. I see this frequently, and these posts usually do not have any means of anchorage at the base. The post in this home was cut about 1/16" short, so it was loose at the base. The top of the post was secured with a 2x4 that prevented it from moving, but clearly this is not enough. Does anyone have a photo or explanation of how this type of post assembly is supposed to be installed?
