Summary
In rural Josephine County outside the Grants Pass and Cave Junction urban growth boundaries, a retaining wall in any residential, commercial or industrial zone cannot exceed four feet in height measured from the bottom of the footing. Retaining walls sit alongside a separate seven-foot sight-obscuring fence limit, and both give way to the county's corner-lot vision clearance triangle.
In any residential zone, a retaining wall not over four feet in height as measured from the bottom of the footing, and a sight-obscuring fence or wall, not to exceed seven feet in height, may be located or maintained in any interior yard except where the requirements of the vision clearance area, pursuant to JCC § 19.73.020, apply ...

Full Breakdown
030(A) caps retaining walls in residential zones at four feet, measured from the bottom of the footing, and the same limit carries over to commercial and industrial zones under subsection (B). Both subsections let the wall sit in any interior yard, and both let a sight-obscuring fence or wall up to seven feet accompany it, except where the county's vision clearance triangle applies. 020, blocks any fence, wall, hedge or vegetation over three feet within 15 feet of a corner lot's street intersection or seven and one-half feet of an alley intersection, measured from the edge of the improved roadway.
In commercial and industrial zones, a sight-obscuring wall may also sit in the front yard, but only up to three and one-half feet, half the interior-yard limit. Fences without sight-obscuring materials may be placed directly on the property line in every zone the section covers. 020 requires written notice of an alleged violation, citing the section violated and the corrective options, before the county escalates. 040. 010 sets the penalty on conviction at up to $500 for a noncontinuing offense and up to $1,000 for a continuing one. 030 and was last amended by Ordinance 2025-003 on November 13, 2025.
Violations & Fines
Building a retaining wall over four feet without site plan review, or placing one inside the vision clearance triangle, is a Rural Land Development Code violation. The Planning Director investigates, issues written notice under JCC § 19.19.020, and allows up to 30 days to correct the wall before referring the case to the District Attorney or the Board of County Commissioners. Conviction carries a fine up to $500 for a single violation or $1,000 if the violation continues.
