No statewide ADU law - entirely local municipal control. Oklahoma City Council approved ordinance easing ADU restrictions on May 22, 2025, making it easier for homeowners to add housing on their land. Oklahoma City has specific landscaping criteria for vegetation type and placement around ADUs to ensure they blend with local character. ADU approval shaped by individual municipal zoning codes rather than state mandate. Tulsa and other cities may have different local approaches. Oklahoma represents traditional local control model without state intervention, similar to Texas approach.
