Zoning, building permits and septic rules in Town of Wells, Wisconsin

Rules another office applies inside Town of Wells

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

• Septic permitRequired

  New structures inside Wells town's limits that require connection to a private onsite wastewater treatment system

  • A building permit may not issue for such a structure unless a compliant private on-site system already exists or all permits necessary to install one have been obtained (Wis. Stat. 145.195(1)).
  • Before issuing a building permit for construction on property not served by a municipal sewage treatment plant, the county, city, town or village must determine that the construction does not interfere with a functioning private on-site system (Wis. Stat. 145.195(2)).
  • Which local unit issues the sanitary permit for Wells town was not confirmed; see the septic authority claim.

  “No county, city, town or village may issue a building permit for construction of any structure requiring connection to a private on-site wastewater treatment system unless a private on-site wastewater treatment system satisfying all applicable regulations already exists to serve the proposed structure or all permits necessary to install a private on-site wastewater treatment system have been obtained.”

• Building in a floodplainRequired

  Development on land inside Wells town's limits that is near water or within a mapped floodplain; the county page names Wells among the towns to contact before construction

  • Monroe County's zoning department page names Wells among the towns where property near water, or in one of the listed towns, should contact the county office before beginning construction.
  • A floodplain land use permit is required before starting work in a floodplain, including filling and material removal, according to the same page.
  • The county page notes that updated floodplain maps are proposed for Monroe County in 2026; the adopted map in effect for a given parcel was not confirmed.
  • Related county ordinances listed on the page are county zoning chapter 47, floodplain zoning chapter 50 and shoreland zoning chapter 53.

  “Floodplain Land Use Permit Application -This permit must be obtained before starting any work in a Floodplain including filling, gratin g and material removal.”

• Permit processPartial

  County zoning permit applications for land inside Wells town's limits (a town, not a city or village)

  • The county zoning department page says its permit applications are for unincorporated areas of Monroe County only, and directs applicants on land within a city or village to that municipality.
  • The page links permit application forms but the full process was not opened; whether Wells town falls under county permits depends on the unresolved zoning status.

  “Note the following applications are for unincorporated areas of Monroe County only. If the project site is within municipal boundaries of a city or village please contact that respective municipality for permit applications.”
