Lee's Summit, MO Fence Regulations: Fence Permit Requirements (2026)

The rule sits in the Unified Development Ordinance's residential accessory-use standards for fences and walls. Anything six feet or under, front-yard decorative fencing with two-inch slat spacing capped at four feet, or a rear-yard fence up to six feet, needs no city sign-off. Cross the six-foot line and the calculus changes: the Building Official must issue a permit first, and if the fence is over six feet and was required as part of a preliminary development plan for a subdivision, the applicant must also secure final development plan approval before that permit can be issued.

The same permit trigger applies to major fence replacement work, not just new construction, so a homeowner rebuilding half or more of an aging six-foot-plus privacy fence cannot skip the permit by calling it a repair. Materials are restricted too: residential fences may use only wood, vinyl, steel, masonry, or wrought iron, limited to two materials across the main face, with post caps and similar accents allowed on top of that. Design standards require the finished side to face outward from the property, with posts and support beams kept to the inside or built into the finished surface.

Fences along an arterial or collector street must include a gate opening per lot so the strip between the fence and the street can still be mowed and maintained. The city's separate encroachment policy layers on additional restrictions for any fence, wall, or retaining wall placed near an easement or right-of-way.
