Before You Build in Yorba Linda, CA: Permit & Rule Checklist (2026)

Yorba Linda caps front-yard fences at 36 inches directly in front of the dwelling, with wrought iron up to five feet elsewhere in the front yard. Side and rear fences may reach six feet.

Yorba Linda's fence material standards favor wrought iron and masonry in front yards, restrict chainlink to non-front locations, and set decorative-element allowances under YLMC 18.10.130.
