Medina, OH Building Setbacks & Zoning: Lot Coverage Limits (2026)

Section 1105.95 defines 'maximum lot coverage' broadly: the greatest amount of any hard-surfaced, man-made area that does not readily absorb or retain storm water, including building roofs, parking and driveway areas and sidewalks, that is permitted by zoning district on an individual lot. The definition itself uses a seventy percent example only to illustrate the math, stating that a maximum lot coverage of seventy percent (70%) means seventy percent of the lot can be covered by hard, impervious surface; the actual limit is set district by district in each zone's own Lot Development Standards table, not by the definition section.

For the R-1 Low Density Urban Residential District, Section 1121.05 sets Maximum Lot Coverage at 50%, alongside the district's other lot standards of a 10,000-square-foot minimum lot size and an 80-foot minimum lot width. That figure covers everything counted under Section 1105.95's storm-water-based test, not just the footprint of the house itself; driveways, patios, sidewalks and detached accessory structures all count toward the 50% ceiling along with the principal building's roof. Other residential districts set their own percentages in their own Section X.05 tables; the O-C Open Space-Conservation District, for comparison, caps coverage at a stricter 20% under Section 1115.05 because of its conservation purpose.

A property owner adding a patio, pool deck or oversized driveway that would push a lot over its district's percentage needs to either redesign the addition or apply for a variance from the Board of Zoning Appeals before proceeding, since the Zoning Certificate the Planning Director issues checks proposed coverage against the district table.
