Zoning, building permits and septic rules in Town of Wellton, Arizona

Town of Wellton’s own rules

• InspectionsLimited

  Manufactured home placement inside Wellton town limits

  • Inspection requirement is stated for manufactured homes set above ground; no general inspection schedule for other residential or commercial construction was located in the sources opened.
  • The placement permit fee covers administration and inspection costs.

  “all manufactured homes, which are set above ground level, shall be skirted at the time of inspection.”

• Local zoningPresent (with conditions)

  All land inside Wellton town limits; the Town of Wellton adopts and administers its own zoning ordinance (Development Code of the Town of Wellton, Arizona)

  • Opt-out window: property owners who wished not to use the new zoning districts created by ordinance 159 had to opt out within one year of October 4, 2024; that window has passed as of the 2026-11-01 extraction date.
  • Code text in the source shows amendments by ordinance #161 (December 3, 2024) and ordinance #162 (August 5, 2025); this claim relies on the code as posted, not on a separately verified amendment history.
  • Annexed land is zoned to a district no more intense than the county district, and Yuma County building permits in annexed areas transfer to the town zoning administrator (see building permit claim).
