Carmichael FAQ
Do I need a permit for a 3-foot Carmichael retaining wall?
Not if it retains 4 feet of soil or less and has no surcharge above it. A 3-foot wall with a sloping landscape above can require a permit because of the surcharge.
Florin FAQ
Is a 3-ft garden wall exempt?
Yes, if it supports no surcharge and is under 4 ft. Stacking multiple short walls to total over 4 ft may still trigger engineering review.
