Full Breakdown
Olathe's Unified Development Ordinance ties height limits to zoning district. In the R-1 Single-Family district, the dimensional standards table caps residences at 2½ stories/35 feet across every lot configuration option, while nonresidential uses in the same district may reach 75 feet. UDO § 18.30.110 measures height from average ground level to the roof's highest point (or a 12-foot story equivalent where height isn't set in feet) and exempts chimneys, spires, church steeples and monuments from the district cap, though water towers and other accessory towers must still comply. Nonresidential structures taller than 35 feet must be set back from every property line a distance at least equal to their height.
Violations & Fines
Exceeding the 35-foot/2½-story residential cap without a variance from the Board of Zoning Appeals is a zoning violation; nonresidential buildings over 35 feet that skip the height-equal setback also fail plan review.
