Plymouth, MN Fence Regulations: Neighbor Fence Rules (2026)

Plymouth's zoning code addresses one specific boundary-fencing scenario directly: where the rear lot line of a residential lot is common with the side lot line of an abutting lot, City Code Section 21130.01, Subd. 5(g) requires that portion of the rear lot line, equal in length to the required front yard setback of the abutting lot, to be fenced. The fence built to satisfy this requirement must comply with the specific fence standards in Subd. 5, meaning it is measured and limited the same way as any other fence under the section: height from adjoining grade to the top of the support posts, materials meeting the opacity and design rules, and setback treatment consistent with the district. This provision exists because a rear-to-side lot line configuration otherwise leaves a gap in visual screening between backyards and the neighboring side yard, where the abutting home's front-facing exposure would otherwise run unscreened into the rear lot.

Outside this specific common-line situation, Plymouth does not otherwise assign shared responsibility for boundary fences between neighbors: the general permit, height, material and setback rules in Subd. 1 through Subd. 6 apply to whichever owner installs a fence, and the code does not create a cost-sharing or maintenance-splitting obligation between adjoining owners beyond each owner's duty under Subd. 4(d) to keep their own fence in reasonable repair and free of nuisance conditions, since both sides of a fence must be maintained without becoming a danger or a public or private nuisance.
