Some RestrictionsNeighbor Fence Rules
Lake Forest's code does not assign cost responsibility for shared boundary fences; that is governed by California Civil Code Section 841, the Good Neighbor Fence Law. Adjoining owners are presumed equally responsible for a boundary fence's reasonable costs, and a 30-day written notice is required before incurring those costs.

Under the adopted 2022 California Building Code, retaining walls over 4 feet (measured from the bottom of the footing) or any wall supporting a surcharge require a building permit.
