What is the maximum height of concrete block piers under a mobile home?

Tuesday, January 5, 2021

Single block piers cannot exceed 36-inches, measured from top of pad or footing to top of concrete block stack, including 4-inch cap block. Maximum height reduced to 24-inches at corners. All piers over 36-inches and corner piers over 24-inches must be double-stacked block, and piers over 52-inches must have engineering specifications.
