From the South Dakota guide
Eight South Dakota counties do not require a residential building permit in unincorporated areas: Tripp County, Corson County, Jones County, Oglala Lakota County, Ziebach County, Campbell County, Buffalo County and Haakon County.1 Another 11 counties require a permit only in some cases, and 47 require one.23 The no-building-codes county list compares them.
The "limited" label covers different things. Custer County's entry reflects building permits for larger structures, while Todd County, Dewey County, Harding County, Yankton County, Aurora County and Potter County are listed as limited because of the statewide electrical wiring permit.2 Read the individual county page before assuming a limited county has no permit at all.
