Summary
Total lot coverage from every structure on a property, including the house and all accessory buildings, cannot exceed the maximum percentage Zoning Table A sets for that district under Section 17.12.070(B)(3). Most residential and commercial districts cap coverage at 75 percent, the F-1 Floodway district drops to 10 percent, and the CON Conservation district allows 30 percent.
17.12.070(B)(3): 'Total lot coverage for all structures on the lot must not exceed the maximum allowed per Table A, at the end of this Title.' Table A, Standards for the Principal Building on Individual Lots, Maximum Lot Coverage column: R-1 75%; C-1 75%; W-I 75%; F-1 10%; CON 30%.
Full Breakdown
070(B)(3) ties lot coverage directly to Table A, the standards table at the end of Title 17 that fixes a maximum-lot-coverage percentage for every zoning district alongside height, frontage, and yard requirements. The cap counts every structure on the lot together, not just the principal building, so a homeowner already near the limit with the house alone can be blocked from adding a detached garage, pool house, or oversized shed even if that new structure meets every individual setback. Across the county's agricultural and residential districts (A, R-1 through R-5) and its commercial and industrial districts (CO-1, CO-2, C-1, C-2, C-4, W-R, W-I, M-1 through M-3), Table A sets the same 75 percent maximum lot coverage.
Two districts break from that pattern: the F-1 Floodway district caps coverage at just 10 percent, reflecting the flood-conveyance purpose of that district, and the CON Conservation district allows 30 percent. 5 acres or more exceed the principal structure's own footprint, up to an aggregate 5,000 square feet, without that added area being treated as exceeding the district maximum. Table A's coverage figures sit on their own line for each district and are not modified by any of the table's footnotes, unlike the frontage and yard columns in the same table.
Violations & Fines
Exceeding the maximum lot coverage for a district is enforced as a Title 17 violation: the Area Plan Commission issues a Notice of Ordinance Violation, and Section 17.36.150 sets civil penalties of up to $500 for a first offense, rising to $1,000, $2,500, $5,000, and $7,500 for further violations within twelve months, with continuing noncompliance counted as a separate violation each day.
