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

    • Accessory buildings also need a permit; approval is issued by Marathon County and a hard card is posted
    • The county, not the town, issues the permit approval, so the county is the rule-maker for this claim

  • Septic permitRequired

    New home construction inside Spencer town needing a private septic (sanitary) permit before building permit

    • Sanitary permit is obtained through a plumber for a home; then the county planning and zoning department is called for the application process
    “in the case of a home, contact your plumber to get a sanitary permit.”
