Full Breakdown
Jackson County's Unified Development Code caps buildings in the Residential Estates District (RE), the county's 2-acre-minimum-lot zoning for unincorporated land, at 35 feet under the Exhibit 240.10 dimensional standards table, Jackson County Code § 24004.4.f. The same 35-foot cap recurs in the county's other unincorporated single-family districts (RS, RU) under their own exhibits. This only governs unincorporated Jackson County under § 24001.4; Kansas City, Independence, Lee's Summit, Blue Springs, Raytown and Grandview each administer their own zoning code with separate height rules that a resident of those cities must check instead.
Violations & Fines
Building over the district height cap without an approved variance is a County ordinance violation under § 24001.12: up to one year in county jail or a $1,000 fine, and each day the violation continues counts as a separate offense.
