Full Breakdown
Edmond Title 22 defines a "garage apartment" as a dwelling unit for one family erected connected to a private garage. The zoning code names garage apartments as a housing type in the C-3 high-density multi-family district's purpose statement, but the only district use table that lists "single-family detached dwelling with or without garage apartment" as a permitted-by-right use is D-1-NRC, Restricted Commercial-Nonresidential Conversions. In D-1-NRC, that use carries the district's standard yard requirements: a 25-foot street yard, a 30-foot rear yard (reduced to 10 feet with a dedicated alley), and a 5-foot side yard, with no minimum lot size or height cap set.
Violations & Fines
A garage apartment built in a district whose use table doesn't list it, or that ignores the D-1-NRC yard setbacks, will fail zoning review and can be ordered removed or converted.
