Summary
Summit County sets no countywide lot-coverage or maximum-building-footprint rule. The percentage of your lot that structures may cover is set by your city, village, or township zoning code. Townships derive this authority from ORC 519.02.
The board of township trustees may regulate by resolution, in accordance with a comprehensive plan, the location, height, bulk, number of stories, and size of buildings and other structures, the percentage of lot areas that may be occupied, set back building lines, and the sizes of yards, courts, and other open spaces.
Full Breakdown
Maximum lot coverage, the share of a parcel that buildings and sometimes impervious surfaces may occupy, is a local zoning standard in Summit County, not a county rule. Municipalities apply their own zoning codes; townships adopt coverage limits under ORC Ch. 519. ORC 519.02 authorizes township trustees to regulate the bulk and size of buildings and to establish the percentage of lot areas that may be occupied. Coverage caps vary by district and are commonly stated as a maximum percentage of lot area. The county's riparian setback (Chapter 937) can further reduce buildable area on stream-adjacent lots. Confirm your district's coverage limit with your local zoning office.
Violations & Fines
Exceeding permitted lot coverage leads to denial of zoning approval, a violation notice, fines, and possible orders to remove the excess structure or impervious area.
