North Las Vegas FAQ
Can I stack garden blocks up to 3 feet without a permit?
Decorative garden borders under 30 inches are exempt. Once you are retaining actual slope or soil above 30 inches, a permit is required even for stackable block.
Why do desert retaining walls need drains?
Flash floods and summer monsoon storms saturate backfill. Without weep holes, hydrostatic pressure can blow out a wall in minutes. Drainage is required by code and good practice.
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.
