Fort Smith Zoning & Land Use Guide
Key Zoning Facts
Fort Smith Zoning Overview
Fort Smith is the second-largest city in Arkansas, located on the Arkansas-Oklahoma border at the confluence of the Arkansas and Poteau Rivers. The citys zoning addresses its heritage as a frontier military post and river trading center, with ongoing efforts to revitalize the downtown and riverfront areas. Fort Smiths economy includes manufacturing, healthcare, and education, and the citys land use patterns reflect the transition from heavy industry to a more diversified economic base.
Key Zoning Districts
Fort Smith uses a district-based zoning system with residential, commercial, and industrial classifications. Arkansas does not mandate a statewide residential building code, so local jurisdictions adopt and enforce their own building codes and development standards. Most larger Arkansas cities have adopted editions of the International Building Code.
ADU Regulations
Arkansas does not have a statewide ADU law, so accessory dwelling unit regulations are determined entirely by local ordinance. Fort Smith addresses accessory structures through its zoning code. Contact the local planning department for current requirements regarding ADU permissibility, size limits, and permitting procedures.
Development Process
Building permits are processed through the local building and planning departments. Projects must comply with the locally adopted building code and zoning ordinance. Rezoning requests and variances typically go through the planning commission and board of adjustment.
