The 75 Percent Masonry Rule and What It Means for Paint
Castle Hills Code Chapter 50 requires a dwelling be not less than 75 percent masonry on its overall exterior walls. The code defines masonry as stone, brick, concrete masonry units or rock laid up unit upon unit set and bonded to one another in mortar. That 75 percent is measured across the whole wall area, not the first floor only. It is why so much of this city reads as brick and stone from the curb.
