Dayton, Ohio Zoning Districts: What Do They Mean?
Zoning districts are areas regulated by specific laws that determine land use, building types, and development rules. Each district below shows its zone type. Dayton's ordinance does not state permitted uses as citywide flags, so they are read from each district's own table rather than summarised here.

|---|---|---|---|
ER-4 Eclectic Single Family Residential | - | 5,508.2 ac | Standards & uses → |
SR-2 Suburban Single Family Residential | - | 4,157.2 ac | Standards & uses → |
MR-5 Mature Single Family Residential | - | 3,867.6 ac | Standards & uses → |

Dayton regulates land through 26 zoning districts, and the residential and commercial districts are prefixed by neighborhood character rather than by density.
Three prefixes run through the roster: Eclectic, Mature and Suburban. Eclectic Single Family Residential is the largest district in the city at roughly 5,508 acres, Suburban Single Family Residential covers about 4,157 and Mature Single Family Residential roughly 3,868. The same prefixes apply to the multifamily and commercial districts.
Naming a district eclectic is unusual and informative: it describes a neighborhood of varied building types and ages rather than a uniform pattern, which is a real condition in an older industrial city.
The Well Head Operation district at roughly 2,272 acres is the distinguishing classification. It protects the wellfield that supplies the city's drinking water, and zoning it explicitly rather than through an overlay means the constraint is part of the district itself.
An Airport District covers roughly 3,215 acres, the fifth largest classification, and a Campus Institutional district about 1,324.
Park And Open Space covers roughly 3,714 acres.
A Transitional district covers roughly 459 acres, and an Urban Business District about 493. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
