Zoning, building permits and septic rules in Portage Township, Indiana

Rules another office applies inside Portage Township

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

• Building permitRequired

  New construction, additions, alterations, repairs and remodeling in the unincorporated part of Portage township (5-digit address area of the St. Joseph County/South Bend Building Department)

  • Permit must be obtained in advance; work may proceed only after the permit is issued.
  • If work proceeds without a required permit, the fee schedule says permit fees are tripled as a penalty.
  • Parts of Portage township inside the City of South Bend are under city jurisdiction of the same joint department; this claim is for the unincorporated portion.
  • The fee schedule states the towns of Lakeville, North Liberty, Osceola, Roseland and Indian Village are covered for building code inspection, not for Portage township.

  “no person, company, or corporation shall perform or cause to be performed any work on or in the unincorporated areas of st. joseph county, city of south bend, towns of lakeville, north liberty, osceola, and roseland, and indian village without obtaining in advance a permit from the building department.”

• Septic permitRequired

  New construction, replacement, and repair of septic systems for one- or two-family dwellings in St. Joseph County, including Portage township

  • Obtaining the health department permit does not release the owner from other required permits or approvals.
  • A copy of the applicable permit must be on site at all times during construction of any septic system.
  • Commercial systems need separate commercial permits; this claim covers residential.

  “residential permits shall be required for the following: 1. one- or two-family dwelling;”
