Recently we have been having a lot of people come in to remove a wood deck and install either brick paver patios or concrete patios. These are generally from a home with a crawl or basement. Top of foundation is supposed to be 6 inches higher than grade and with 2x10 floor joists this usually puts the 1st floor to grade at 18.75 inches. Per 311.4.3 of the 2006 IRC, I have been asking for the landing outside of the exterior door. Of course the contractor just wants to install the patio 7 3/4" lower than the 1st floor which means pouring the patio right up against the siding because a home with 2x10 floor joists with a 7 3/4" drop will produce this situation. I keep telling them they have to drop their patio to 6 inches below grade but create a landing and steps with a foundation or using 8" diameter concrete piers.
Does anybody else run into this these days? Its usually a big battle once in a while when I don't let them build up grade against the foundation wall and sometimes siding. The landing always gets flashed but the patio still needs to be 6 inches below top of foundation.
