ADU Permit in Edmond, OK — Cost, Requirements & Process
An accessory dwelling unit (ADU) permit in Edmond covers a secondary dwelling — detached or attached — on a residential lot. ADUs are permitted only in A and A-1 single-family districts, subject to lot size minimums, an owner-occupancy requirement, and an 800 sq ft maximum habitable area set in Title 22.
The owner must occupy either the primary dwelling or the ADU. This is enforced through an affidavit at permit application and through the city's rental registration when the unit becomes a long-term rental. Short-term rentals (Airbnb, VRBO) of an ADU may face additional regulation under Edmond's evolving short-term rental rules — verify the current ordinance before designing for STR use.
ADUs require a full plan submittal as a separate dwelling — site plan, architectural drawings, foundation, framing, energy compliance, and trade sub-permits for electrical, plumbing, and mechanical. The lot must be at least the district minimum plus 2,500 sq ft (so 14,500 sq ft in A district, 15,000 sq ft in A-1). One additional off-street parking space is required.
