St. Peters, MO Fence Regulations: Neighbor Fence Rules (2026)

The St. Peters Municipal Code does not split boundary-fence costs between neighbors; instead, Section 405.360(D)(3) places sole responsibility for upkeep on 'the owners of residential properties,' whether the fence sits on a shared line, a side yard, or a rear yard. That owner must also remove the fence outright if it 'becomes unsightly or a menace to public safety, health or welfare,' language broad enough to cover a rotted, leaning, or partially collapsed structure a neighbor might otherwise complain about. The Article's general provisions reinforce the same standard: Subsection (B)(8) defines 'good condition' for every fence in the City to include, at minimum, replacing damaged boards, staining or painting worn surfaces, and removing rust.

Subsection (B)(6) separately bars building a fence that encloses or blocks a stormwater catch basin, culvert, or other stormwater structure, and makes the City Engineer responsible for inspecting such violations and reporting them in writing to the Administrative Officer. Because the ordinance addresses maintenance and removal rather than construction cost-sharing between adjoining owners, a resident whose neighbor lets a shared fence deteriorate has a City code-enforcement complaint route through the ordinance's maintenance duty rather than a specific cost-splitting rule.
