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

Total lot building coverage is defined in § 1115.03(c)(4) as "the percentage of the lot that is occupied by the ground area of a building and its accessory buildings," and the same subsection specifies that fences, walls, and gates are excluded from that calculation, so a deck footing counts but a privacy fence does not. The actual percentage varies by district and use: Table 1109.02.1 for the Low Density Residential (R-LD) district sets a 50% maximum for a one-unit dwelling, 60% for a townhome, and 60% for a two-unit dwelling, alongside the district's 5,000-square-foot minimum lot for a one-unit dwelling and 4,000-square-foot minimum for a townhome.

By contrast, the Agriculture (R-AG) district's Table 1109.01.1 lists "N/A" for total lot building coverage, meaning R-AG has no maximum footprint limit at all, and the Heavy Commercial Corridor (C-HC) district similarly shows "N/A" under Table 1110.03.1. Coverage is calculated per lot, not per building, so accessory structures such as detached garages, sheds, and covered porches count toward the same cap as the principal dwelling. A property owner proposing to exceed the applicable percentage in a district that sets one, such as R-LD, needs a variance from the Board of Zoning Appeals rather than a building permit alone, because the coverage figure is a dimensional standard under Title Three of the Zoning Code.
