Henderson FAQ
When does a Henderson retaining wall need a permit?
Any retaining wall over 4 feet tall measured from footing to top of wall, or any wall supporting a slope, pool, or structure, requires a permit and engineered drawings.
Why is engineering required on hillside lots?
Ascaya, MacDonald Highlands, and Black Mountain areas have expansive soils and steep grades where unengineered walls fail during monsoon runoff.
Paradise FAQ
Do I need a permit for a 3-foot block retaining wall in my backyard?
Only if it is NOT supporting a surcharge load. If there is a driveway, pool, or sloped soil above the wall, a permit is required regardless of height.
Can I tier two 3-foot walls to avoid the 4-foot permit threshold?
Only if the walls are separated horizontally by more than twice the height of the lower wall. Otherwise they are treated as a single combined wall and a permit is required.
