Summary
Livermore treats barbed wire, concertina wire, razor-cut wire, and fencing topped with spikes, nails, or broken glass as a public nuisance per se on residential property. LMC § 8.14.030(E)(5) bans these materials outright in residential zones, and any fencing or screening material that violates the City's separate development code fencing standards is likewise a declared nuisance subject to abatement.
On property in residential zones, the use of barbed wire, concertina wire, razor-cut wire, fencing topped with spikes, nails, broken glass or other such similar fencing material, and any fencing of screening material that violates LDC 4.05.040.
Full Breakdown
040" is declared a public nuisance per se. 040 so that any fence violating those separate height, location, or material rules is also automatically a nuisance under this chapter, even though the underlying development code standard is not itself part of the nuisance chapter. 15 governs the notice, administrative-hearing, and cost-recovery steps if the fence is not removed.
Violations & Fines
Maintaining barbed wire, concertina wire, razor-cut wire, or fencing topped with spikes, nails, or broken glass on residential property is unlawful under LMC §§ 8.14.030(E)(5) and 8.14.050, with each day the fence remains a separate offense. The City proceeds through the standard notice-and-order-to-abate sequence in Chapter 8.15, and an owner who does not remove the fencing after notice faces an administrative charge, City abatement of the fence, and a lien for the cost under §§ 8.15.150 and 8.15.170 through 8.15.190.
