Rancho Cucamonga FAQ
Do I need a permit to replace my existing 6-foot wood fence?
Usually no, if you're replacing like-for-like at the same location and height. A permit is required if you change material to block, increase height, or build a retaining wall.
What about a block wall?
Any masonry or block wall requires a building permit in Rancho Cucamonga regardless of height because it needs structural footing review.
