Full Breakdown
The UDO limits retaining walls near the front property line to 4 feet in height and requires design review for taller walls elsewhere on the lot. Walls visible from an adjoining property must be tiered so no single tier exceeds 20 feet, and any retaining wall visible from the public right-of-way must be built of decorative concrete modular block or faced in stone, brick, or textured cement masonry rather than left as bare poured concrete.
Violations & Fines
Building a wall that exceeds the front-setback height limit or skips the required tiering/facing triggers a stop-work order and code enforcement action through Planning and Development.
