Springdale, AR Accessory Structures: ADU Permits (2026)

The two-track permitting process for a Springdale ADU works as follows. Zoning Track: The applicant first verifies that an ADU is permitted in the underlying district under the Springdale zoning code. If permitted by right (a so-called "as of right" use), a zoning permit issues from Planning & Community Development upon a showing of compliance with dimensional standards. If permitted by special use permit or conditional use, the application goes to the Springdale Planning Commission (established under A.C.A. §14-56-404) which holds a public hearing with notice. If a variance is needed, the application goes to the Board of Adjustment under A.C.A. §14-56-416(b)(2)(C)(ii). The variance standard under Arkansas law generally requires unique physical conditions, hardship not self-created, and consistency with the spirit of the ordinance. Building Track: After zoning approval, the applicant submits construction documents to the Building Official under the locally adopted IRC. Plan review confirms structural, electrical, plumbing, mechanical, and energy provisions of the IRC for one- and two-family dwellings (or IBC for townhouses or larger configurations). Inspections occur at footing, foundation, framing, rough-in, insulation, and final stages. A Certificate of Occupancy is issued before the ADU may be occupied. Springdale typically requires separate utility metering or affidavits for ADUs with kitchens — water and sewer service is provided by Springdale Water Utilities. Properties in the FEMA Special Flood Hazard Area along Spring Creek and other local waterways face additional floodplain permit review.
