Zoning, building permits and septic rules in Wiota, Iowa

Rules another office applies inside Wiota

Wiota does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

• Who permits septicMixed (with conditions)

  Private sewage disposal systems (PSDS) on homes inside Wiota city, Iowa: the state rule applies, and the administrative authority is the department or the local county board of health

  • The state rule (567 IAC 69) defines the administrative authority as the department or the local county board of health, as authorized by Iowa Code section 455B.172 and chapter 137.
  • The Cass County board of health's role for Wiota addresses was not separately verified on an official page.
  • The IAC copy opened (dated 07-08-2026) shows a rescission date of 7/12/31; a 2025 notice of intended action proposing a new Chapter 69 was seen in search results and not checked.

  “"administrative authority" means the department or the local county board of health as authorized by iowa code section 455b.172 and chapter 137.”

  • Permit issued by the administrative authority (department or local county board of health).

  • Where a publicly owned treatment works (POTW) is available, or a local ordinance requires connection to it, a private sewage system may not be installed.
  • A POTW is treated as unavailable when it is more than 200 feet from the proposed building or drainage facility on a lot that abuts and is served by a POTW.
