Local and county notes for Kenneth City
Florida did not adopt the model code exemption for retaining walls 4 feet or less. Section 105.2 of the Florida Building Code, Building lists only certain gas, mechanical and plumbing work as exempt, so any threshold for small landscape walls is set locally. Section R404.4 of the Florida Building Code, Residential requires an engineered design for a wall that retains more than 48 inches of unbalanced fill, or a wall over 24 inches that resists loads in addition to soil. Where one retaining wall spans several residential lots, Florida Statutes 553.79(1)(i) requires the local government to issue one permit for the whole wall. This wall will hold up a driveway, patio, structure or sloped ground, which puts extra load on it (a surcharge). Model code exemptions for short retaining walls specifically exclude walls supporting a surcharge. Surcharged walls commonly need an engineered design, drainage behind the wall, and an inspection, because a failure can undermine whatever sits above it.
