How Edmond Handles Accessory Structures: A Practical Guide
Edmond maintains 82 local ordinances across all categories, and 2 of those deal specifically with accessory structures. Here is a breakdown of what the city actually requires, what is prohibited, and where Edmond falls on the strict-to-permissive spectrum compared to other cities.
Shed & Carport Rules
Edmond caps residential accessory structures like sheds at 20% of the home's floor area or 600 square feet, whichever is larger, and requires a principal house on-site before a permit issues.
Key details: Urban lot accessory cap: 20% of house or 600 sq ft. Rear setback (single-story): can reduce to 5 feet. Street-yard sheds: barred under 2.5 acres. Permit required: needs existing principal residence.
Building a shed without a permit, in an easement, or oversized for the lot can result in a stop-work order, permit denial, or a Board of Adjustment appeal to remedy.
ADU Rules
In Edmond's D-1-NRC district (Restricted Commercial, Nonresidential Conversions), a single-family detached dwelling is listed in the use table "with or without garage apartment." The lot carries a 25-foot street yard, a 30-foot rear yard (10 feet with a dedicated alley), a 5-foot side yard, no minimum lot size and no stated height cap.
Key details: District: D-1-NRC, Restricted Commercial, Nonresidential Conversions. Garage apartment: Listed with single-family detached dwelling; Section 22.4.2 treats check in P column as by right. Street yard: 25 feet. Side yard: 5 feet. Rear yard: 30 feet; 10 feet with a dedicated alley.
Title 22 is enforced by the City Manager or his designee under Section 22.8.2. Building a garage apartment that crosses the 25-foot street yard, 30-foot rear yard or 5-foot side yard lines, or converting the residence to a commercial use, violates the Title. Under Section 22.8.6(G) a conviction is a Class B offense under Section 2.56.210 of the City Code, each day the violation continues is a separate offense, and liability falls on the property owner as well as agents or employees acting for the owner.
The Bottom Line
Edmond's accessory structures rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Edmond is broadly strict or permissive.
