Full Breakdown
Lake Forest amends the California Building Code's permit-exemption list at Municipal Code Section 8.02.020(A), which rewrites Chapter 1, Division II, Section 105.2, Building Item 2: walls and fences other than swimming pool barriers are exempt from a permit only when six feet or under. Anything taller needs a Building Division permit, as does any pool barrier regardless of height, and any wall or fence that a project's approval conditions specifically require, even if under six feet. The Building Official, housed in the Community Development Department, issues fence permits and enforces this section.
Violations & Fines
Building or extending a wall or fence over six feet, or a required pool barrier, without a permit is a misdemeanor punishable by up to $1,000 and six months in jail per day of violation.
