Full Breakdown
On infill residential lots in Kansas City's R-80 through R-0.3 districts, the Zoning and Development Code caps maximum building coverage at 50% of the lot area and maximum impervious surface coverage, roofs, concrete, and asphalt combined, at 75% of the lot area. An infill residential lot is one within 200 feet of, and on the same block face as, existing development in an established neighborhood. Detached accessory buildings on any residential lot face a separate cap: their combined footprint can't exceed 40% of the actual rear yard area.
Violations & Fines
The city planning and development director may approve a project that falls within 10% or less than a foot of any infill standard, whichever is less. Beyond that, non-compliant plans are denied at permit review; built violations are enforced as zoning code violations through the Codes Administration division.
