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

10(b) of the City of Middletown Development Code addresses livable floor area and lot coverage together for residential zoning districts. All single-family dwellings of two stories or taller must have at least 1,700 square feet of livable floor area, dropping to 1,500 square feet for a single-family home under two stories; two-family and three-family dwellings need a minimum of 1,000 square feet of livable floor area per unit, and multi-family dwellings need at least 500 square feet per unit. Immediately after those floor-area floors, division (b)(4) sets the impervious surface ceiling: impervious surface, defined to include driveway, walkways, and sidewalks, cannot exceed 30% of the front yard on any residential lot.

10(a)(5)E, a homeowner widening a driveway or adding a walkway has to keep the total paved footprint within that 30% ceiling for the whole front-yard area, not just the driveway itself. The Development Code Administrator in the Department of Community Revitalization/Planning checks this during the certificate of zoning compliance review that a driveway expansion or new walkway triggers, and Table 1204-4's separate minimum lot area and lot width figures for each district (R-1 through R-4) set the denominator against which any coverage question is measured.
