Summary
Unincorporated Canyon County's zoning code requires a sight-obscuring fence or wall to be built of durable material such as wood, brick, masonry block, stone, vinyl or slatted chainlink, and bars scrap lumber, scrap metal, corrugated or sheet metal panels, tarps and plywood, under § 07-02-03. Ordinary confinement fencing elsewhere in the code may still include barbed or netted wire.
FENCE: A barrier built for either confinement of an area or to keep others out of a confined area. A fence may be either affixed to the ground or be placed thereon and may include, but not be limited to, rock, stone wall, retaining wall, shrubs, panels, netted wire, or barbed wire. FENCE (SIGHT OBSCURING): The construction of a solid barrier that blocks the visibility through the fence, and is erected to screen areas from public streets and abutting properties. (1) Allowed Materials: Fences and walls shall be made of high quality, durable materials that require low maintenance. Acceptable materials for a fence include chainlink with slats, wood, brick, masonry block, stone, vinyl, composite/recycled materials (hardy board) or other manufactured material or combination of materials commonly used for fencing. (2) Prohibited Materials: Fences and walls shall not be made of or contain: A. Scrap materials such as scrap lumber and scrap metal. B. Materials not typically used or designated/manufactured for fencing such as metal roofing panels, corrugated or sheet metal, tarps or plywood.
Full Breakdown
Canyon County Code § 07-02-03 draws a line between a plain FENCE, defined broadly to include rock, stone wall, retaining wall, shrubs, panels, netted wire, or barbed wire, and a FENCE (SIGHT OBSCURING), defined as a solid barrier that blocks visibility and screens a property from public streets and abutting land. Only the sight-obscuring category carries a materials standard. Its Allowed Materials clause requires high quality, durable, low-maintenance construction and lists chainlink with slats, wood, brick, masonry block, stone, vinyl, and composite or recycled material such as hardy board.
Its Prohibited Materials clause bars scrap lumber and scrap metal outright, plus anything "not typically used or designated/manufactured for fencing," naming metal roofing panels, corrugated or sheet metal, tarps, and plywood as examples. The county's zoning use matrix at § 07-10-27 ties this standard to specific commercial and industrial uses: several matrix entries, such as outdoor equipment rentals, carry a footnote requiring a sight-obscuring fence built to this § 07-02-03 standard before the county will approve the use. Because ordinary (non-sight-obscuring) fencing is defined separately and is not subject to the prohibited-materials list, a landowner erecting a standard field or livestock fence may still use barbed or netted wire under the general FENCE definition.
This standard applies only to unincorporated Canyon County; a fence inside Caldwell, Nampa, Middleton, Greenleaf, Melba, Notus, Wilder, Parma or Star is governed by that city's own code, not this county provision.
Violations & Fines
A sight-obscuring fence built from prohibited material is a zoning code violation processed under § 07-19-01: DSD issues a request for voluntary compliance giving the property owner ten days to remedy it, followed by a written order of abatement with a compliance deadline and stated penalty if the violation persists. Continued noncompliance is charged as an infraction under the county's general penalty, § 01-01-07, at fifty dollars for a first offense, one hundred for a second, and two hundred for a third, becoming a misdemeanor punishable by up to $1,000 and six months in jail on the fourth and later offenses.
