The four foot rule, and the exception

Walls under four feet are generally exempt in Washoe County. But if a slope, driveway or structure sits above the wall, it is considered surcharged and needs a permit regardless of height.

Terracing as an alternative

Multiple shorter tiers instead of one tall wall improve drainage and often keep you under the permit threshold, while giving you the same usable yard.
