Retaining Wall Installation en Woodland — Preguntas Frecuentes

Do I need a permit for a retaining wall in Sacramento?+

Sacramento County generally requires a building permit for retaining walls over 4 feet tall (measured from the bottom of the footing to the top of the wall). Walls near property lines or public right-of-way may have additional setback requirements.

How high can a landscape retaining wall be?+

Segmental block walls are typically built up to 4 feet without engineering. Walls over 4 feet require a licensed engineer's design and a building permit. Terracing with multiple shorter walls is a common alternative.

How long does a retaining wall last?+

A properly built segmental block wall lasts 50+ years. The key is a compacted gravel base, proper drainage behind the wall, and correct setback on each course.
