Summary
Berkeley bans barbed wire, razor wire, sharp glass, and jagged metal fencing in every Residential District. Existing prohibited fences had to come down by 2004 or 2005 depending on their value, and none may be repaired or expanded once non-conforming.
C. Prohibited Materials in Residential Districts. 1. A fence in a Residential District may not contain strands of barbed or razor wire, sharp or jagged glass, sharp or jagged metal components (e.g., razor-spikes), or similar materials. 2. Prohibited fence materials on an existing fence may not be expanded or repaired. Table 23.304-9 shows the date by which existing non-conforming prohibited fence materials must be removed. | $1,500 or less | October 16, 2004 or within one year from the date such feature became non-conforming, whichever date is earlier | | More than $1,500 | October 16, 2005 or within one year from the date such feature became non-conforming, whichever date is earlier |

Full Breakdown
C flatly prohibits strands of barbed or razor wire, sharp or jagged glass, sharp or jagged metal components such as razor-spikes, or similar materials on any fence in a Residential District. 304-9 set removal deadlines tied to the material's adjusted market value: fencing valued at $1,500 or less had to be removed by October 16, 2004 (or within one year of becoming non-conforming, whichever came first), while fencing worth more than $1,500 had until October 16, 2005 on the same one-year alternative. The code defines adjusted market value as the likely original installation cost reduced 10 percent for every year the fence has been in place.
24. The ban does not reach Non-Residential Districts outright: there, barbed or razor wire is allowed along a street or right-of-way if the lowest strand sits more than 5 feet above ground and the wire is set at least 6 inches inside the property line, though a non-residential lot line abutting a Residential District still has to follow the residential prohibition.
Violations & Fines
Maintaining, repairing, or expanding a prohibited barbed-wire, razor-wire, or sharp-material fence in a Residential District past its Table 23.304-9 removal deadline is treated as a public nuisance, enforceable through abatement proceedings under BMC Chapter 1.24 that can compel removal at the owner's expense.
