Re: SOG foundations

Code requires 6 inch minimum separation for wood framed structures for moisture and termite considerations.  This is typically what is built "pre-landscaping".  Then someone moves in and starts adding lawns, planters, walkways, etc.  Also soil gets shifted around over time, top soils build up, and so on.  The net result is most older residences will not have the minimum separation, regardless of how it was built.

a.  As typically shown on the plans
b.  As typically actually built
