Full Breakdown
UDC § 3.02.10(A) requires a Building Permit for new fences, walls, and screening, a rule that carries forward the older Municipal Code § 151.185 permit clause for 'any fence, wall, or retaining wall.' Subsection E goes further for grade changes: a retaining wall is mandatory 'at all locations where there is a grade separation of more than 12 inches between properties,' though the Director can waive it if the City Engineer approves an alternative design. Subsection G(5) restricts materials to masonry, brick, concrete, or paver block. Where a retaining wall sits below a fence or wall, § 3.01.03(E) governs how the combined height is measured, using the lower adjacent grade or the grade-differential midpoint.
Violations & Fines
Building or replacing a retaining wall without the required permit, or below the mandated 12-inch grade-separation threshold without one, is a code violation subject to a stop-work order, code enforcement action, and required after-the-fact permitting.
