Full Breakdown
The City's amendment to the California Building Code, Municipal Code Section 8.02.020(A), exempts 'walls and fences, other than swimming pool barriers, not over six feet ... tall' from needing a building permit. The exemption carries a carve-out: a wall or fence under six feet that was required as a condition of project approval still needs a permit. Fences taller than six feet require a building permit and must still meet the applicable zoning district's development standards.
Violations & Fines
Building a fence without a required permit exposes the owner to a stop-work order and after-the-fact permit fees through the Building Division; the section itself sets no separate fine.
