Summary
Columbia's Unified Development Code sets no blanket height cap for residential fences in Boone County, they're allowed up to the lot line, but on corner lots, no fence may stand inside the required sight triangle where it blocks a driver's view of traffic.
Except in the M-DT district (section 29-4.2), on any corner space or lot on which a front or side yard is required, no wall, fence, sign, or other structure or no plant growth of a type within a sight triangle which would interfere with traffic visibility, in accordance with city policy based on the Missouri Department of Transportation's Engineering Policy Guide provided plant material reaching no more than three (3) feet or higher at maturity will be allowed.(e)Property edge buffering.(1)Buffering required. Where a property contains at least ten thousand (10,000) square feet of area or more than one thousand five hundred (1,500) square feet of paved area or any vehicle loading/unloading areas, buffering shall be installed as required by Table 4.4-4.(i)To use this table, an applicant identifies the proposed use of the property in Row 3, across the top of the table, and then reads down Column 2 to identify the zoning of the adjacent property along each property line. The box at the intersection of Column 2 and Row 3 identifies the screening and buffering requirement for the applicant on that property line. Different types of screening and buffering may be required on different property lines, as indicated in Table 4.4-4.(ii)Transitional screening shall not be required for urban agriculture and farmer's markets.

Full Breakdown
Under UDC Section 29-4.1(c)(2) (Table 4.1-5), fences and walls in Columbia, Missouri may run right up to a lot's boundary line: the code sets no numeric front, side, or rear height ceiling for a residential yard fence. The one hard limit sits at street corners: Section 29-4.4(c)(5) bars any wall, fence, sign, or structure inside the sight triangle required at a corner lot with a front or side yard, applying the Missouri Department of Transportation's Engineering Policy Guide, with plantings capped at 3 feet at maturity. The M-DT downtown district is expressly carved out and follows its own building form standards instead.
Violations & Fines
A fence obstructing a corner sight triangle is a Chapter 29 violation: the director can order its removal, and noncompliance is a misdemeanor punishable by a $10-$250 daily fine under Section 29-6.6.
