Edmond, OK Accessory Structures: ADU Rules (2026)

Section 22.4.25 governs the D-1-NRC district, a restricted commercial zone meant for neighborhood retail beside low density homes. Its residential block has two entries: a single-family detached dwelling with or without garage apartment, and a two-family dwelling. Edmond's Chapter 9 definition reads "GARAGE APARTMENT. A dwelling unit for one family erected connected to a private garage." So an owner in this district can build a one-family unit attached to the garage, and Section 22.4.2 reads a check mark in the P column as allowed by right, with no specific use permit and no City Council vote. Allowed by right still carries conditions: Section 22.4.2 says permitted uses are subject to all other applicable regulations of Title 22, and subsection (E)(2) points to the Chapter 6 site design standards.

The dimensional standards in subsection (D) apply to the lot as a whole, garage apartment included. There is no minimum lot area and no minimum lot width, so a small lot is not disqualified. The street yard is 25 feet and the side yard is 5 feet. The rear yard is 30 feet, and a footnote cuts it to 10 feet when there is a dedicated alley, which matters for a garage apartment because the garage is the structure sitting closest to the back lot line. Maximum height is listed as None in the table.

Two limits keep the allowance narrow. Subsection (E)(1) says residential structures shall not be converted to a commercial use, so a house with a garage apartment cannot be flipped into a shop. And Section 22.4.2 treats any use not expressly listed as prohibited unless the Planning Director makes a similar use determination under Section 22.4.34, and the D-1-NRC table lists no standalone detached accessory cottage. The section's history line ends with Ord. No. 4086, § 1, May 26, 2026, and the district traces to Ord. 3068 of November 27, 2006.
