Plymouth, MN Fence Regulations: Fence Permit Requirements (2026)

City Code Section 21130.01, Subd. 1 makes a permit mandatory for any fence or wall erected, altered or relocated in Plymouth, with limited exceptions spelled out elsewhere in the section. For agricultural, single-family and two-family uses, Subd. 3(a) calls this a 'no-fee' fence/wall permit: the owner submits a City application form, and unless the fence would exceed seven feet or the wall four feet (which instead triggers a building permit under Section 1015), there is no permit charge. Every application, fee or no-fee, must include a site plan drawn to scale showing the house, any accessory structures or improvements, all public easements, and any required wetland buffers on the lot, together with the exact location of the fence or wall to be built, altered or relocated.

Developer-installed fencing shown on an approved subdivision plat is exempted from the no-fee permit requirement, though a building permit is still required if that fencing exceeds the seven-foot (fence) or four-foot (wall) threshold. For all other land uses, commercial, industrial, institutional and similar properties, fence and wall requests are not processed as a standalone fence permit at all; instead they go through site plan review or a site plan amendment under Section 21045, with the appropriate review fee, plus a separate building permit if the height thresholds are exceeded. Hedges and other plantings never need a permit under this section, though they still must respect the traffic sight visibility rules in Section 21105.05.
