Answers from the rulebook for Odin

Rules another office applies inside Odin

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

  • Building code adoptedAdopted (with conditions)

    Buildings inside Odin city limits that are of a type governed by the Minnesota State Building Code.

    • The statute excludes agricultural buildings except for the stated inspection/rulemaking and skylight provisions.
    • The source does not establish whether Odin administers or enforces the code locally.
    “The State Building Code is the standard that applies statewide for the construction, reconstruction, alteration, repair, and use of buildings”
  • Off-grid sanitationLimited

    New construction or replacement individual sewage treatment systems serving property inside Odin city limits.

    • Treatment and dispersal must comply with Minnesota Rules 7080.2150 and parts 7080.2200 to 7080.2400 as adopted into the applicable local ordinance.
    • This does not identify the local permit administrator or determine public-sewer availability.
    “Treatment and dispersal of all sewage for new construction or replacement ISTS must be in compliance with this part [...] as adopted into local ordinances.”
  • Well permitLimited

    Construction of water-supply, dewatering, or environmental wells inside Odin city limits.

    • Except for the statutory drive-point-well exception, a notification prescribed by the commissioner and the statutory filing fee are required before construction.
    • A drive-point water-supply well constructed by an individual on property used for farming, agricultural purposes, or the individual's abode requires post-construction notification within ten days and no fee.
    • The state notification preempts local permits and notifications unless the commissioner delegates authority.

    drive-point-well notification deadline: <= 10 days after completion (Applies to the statutory individual drive-point-well exception.)

    “a person may not construct a water-supply, dewatering, or environmental well until a notification of the proposed well [...] is filed with the commissioner”

Each answer was extracted from an official source and independently re-checked against that source by a second reviewer. That is an evidence check, not legal advice. Rules change; confirm with the authority before you buy or build.

Unanswered questions are usually a sign that Odin publishes no rule on the point, not that none exists. Watonwan County’s page lists the county offices to call.
