Summary
Pleasanton bans barbed wire fencing in its R-1 and RM residential districts. Municipal Code §§ 18.32.050 and 18.36.050 list barbed wire, or any fence rigged with it to stop people or animals from climbing, among prohibited uses, with narrow exceptions for lots where horse-keeping is allowed or lingers as a nonconforming holdover from earlier agricultural zoning.
Barbed wire fences or any fence which has attached to it, for purposes of prohibiting people or animals from climbing the same, barbed wire regardless of type, with the following exceptions: 1. Where this title specifically allows for the keeping of horses, 2. Where property, although zoned for residential use, has not yet developed pursuant to that zoning and, thus, a great deal of open acreage still remains and is used for the keeping of horses and other animals included in the agricultural district, such usage becoming nonconforming as a result in change in zoning.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: rev 4955754; v17 updated 2026-06-02).
Full Breakdown
050(B), governing the R-1 one-family residential districts, prohibits 'Barbed wire fences or any fence which has attached to it, for purposes of prohibiting people or animals from climbing the same, barbed wire regardless of type,' with two exceptions: where the title specifically allows keeping horses, and where residentially zoned property has not yet been developed under that zoning so open acreage still supports horses and other agricultural-district animals as a nonconforming use after a zoning change. 050(B), governing the RM multi-family residential districts, prohibits the identical material in identical language.
Both sit inside each chapter's 'Prohibited uses' section, meaning barbed wire is not merely discouraged, it is an unpermitted use of the site that cannot be approved through ordinary design review. 090(F), the yard-regulation chapter that applies across zoning districts, allows fences up to eight feet in the C-S, C-A, I-P and I-G commercial and industrial districts for outdoor storage areas, and lets the upper two feet of those fences carry barbed wire, but only with the zoning administrator's permission, which can be refused if the appearance conflicts with the title's purposes or is detrimental to public health or welfare.
The code does not separately name electric or electrified fencing in the sections addressing prohibited fence materials or the yard-fence standards reviewed for this record.
Violations & Fines
Installing or maintaining a prohibited barbed wire fence in an R-1 or RM district is declared unlawful and a public nuisance under § 18.140.010, and the city attorney is directed to institute legal proceedings to abate, remove or enjoin it. Because zoning Title 18 is not among the chapters § 1.12.020 designates as infractions, a violation falls under the code's general misdemeanor penalty, § 1.12.010: a fine up to $1,000, up to six months in county jail, or both.
