Retaining walls in Littlefield, AZ

In Mohave County, retaining walls over four feet tall measured from the bottom of the footing require a building permit. Walls at or under that height are generally exempt, but any wall supporting a surcharge load still requires review regardless of height.

Gravel backfill and a perforated drain pipe are placed directly behind the wall to give water a clear path out. This matters in Littlefield because the caliche layer in local soil blocks natural percolation, so without a built-in drainage path, water pressure builds against the wall.

Concrete masonry unit block and reinforced segmental systems perform well in Arizona because they handle extreme heat cycles and can be built with proper drainage details. The right choice depends on wall height, the load above the slope, and site-specific soil conditions.

If your wall will support a structure, driveway, or other surcharge, engineering review applies at any height.

Yes, a retaining wall next to a casita or accessory structure in Littlefield is a straightforward project when the site is assessed for slope, soil type, and drainage first. Wall height and proximity to the structure determine whether a permit is needed under Mohave County rules.
