Fence Installation Permits in Missouri
Fences are governed mainly by local zoning, not a statewide building permit. Cities set height limits (commonly 3-4 ft in front yards and 6 ft in back and side yards), setbacks, and corner sight-line rules, and many require a zoning permit for any fence. Most jurisdictions exempt fences up to 7 ft from a building permit (IRC R105.2) and require one above that. Replacing a fence at the same height, material, and location usually needs no permit; a fence used as a pool barrier always does.
The Building Code in Missouri
No statewide residential building code (home-rule)
Missouri has no statewide residential building code; cities and counties adopt and enforce their own. Fences are therefore purely a local matter, and rural areas may have no permit requirement at all.
Who Sets the Rules
What's Different in Missouri
With no state code, practice ranges widely. St. Louis and Kansas City generally require a permit for fences over about 6-7 feet, while many smaller jurisdictions require none for a standard residential fence. Confirming with the local building division is essential here.
