19 Miss. Code. R. 7-5.06.8.1 - Placement of Door and Window Support Piers
For all homes, all exterior entry doors shall have piers or a manufacturer's approved support device on each side of the opening. All doors and windows over 48 inches wide shall be properly blocked under each side of the opening (footings for these support piers may be 8" x 16" x 4" concrete pads or equivalent). In the event that an obstruction (electrical, mechanical, plumbing or other device) is directly under one side of the opening, the blocks on that side may be offset up to maximum of 6 inches in either direction of the supported member. Factory installed outriggers and cross members may replace support piers if they are positioned directly below exterior door or window openings less than 48 inches, provided the floor rim joist has not been compromised or damaged.
