Full Breakdown
025 amends Section 105 of the California Building Code as adopted locally. 1 requires any owner or authorized agent who intends to construct, enlarge or alter a structure to first apply to the building official and obtain a permit. " Read together, a fence 6 feet or under that is not a pool barrier can go up without a building permit, but a fence over 6 feet, or a pool safety fence of any height, must go through the standard permit process: an application to the building official, plans adequate for review, and payment of the processing and inspection fees on the city's current fee schedule.
That permit process is separate from the zoning approval a fence may also need. 050. A fence that both exceeds 6 feet and sits in a required setback can therefore require both a building permit and a minor variance before work begins.
Violations & Fines
Building without the required permit is enforceable through the city's Building Division stop-work and correction process; the building official can require the work to cease, plans to be submitted retroactively, and inspection fees paid before the fence is allowed to remain. A fence built over the zoning height limit without the § 21.50.040 minor variance is a separate zoning violation that can require removal or reduction in height regardless of whether a building permit was pulled.
