Answers from the rulebook for Olive Township

Rules another office applies inside Olive Township

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

  • Who permits septicCounty (with conditions)

    On-site septic systems on land inside Olive township, which is unincorporated St. Joseph County; the St. Joseph County Health Department administers the county septic chapter (Code of Ordinances Chapter 51) there.

    • The county health department issues septic permits, soil-report procedures and variances under Chapter 51; state rule 410 IAC is referenced by the chapter.
    • Olive township itself is not shown to adopt any septic rule; no township septic authority was found.
    • Whether any municipality in St. Joseph County has its own septic authority does not change the answer for unincorporated Olive township.
    “the health department may issue policies and procedures concerning the preparation and submittal of soil reports to support any decision concerning septic systems”
  • Septic permitRequired

    New structures served by an on-site septic system on land inside Olive township (unincorporated St. Joseph County).

    • Site activity for the structure (clearing, grading, soil borings, system placement) may not start until the septic permit is issued, so construction may proceed only after the permit.
    • Increasing bedrooms in an existing residence, or moving a structure including a manufactured home to a new location served by an on-site system, requires a septic permit or a written health-department opinion that the existing system is adequate.
    • Permit applications for repair or replacement must include an operational status report prepared by a licensed septic installer or inspector.
    • Designs and drawings for a septic permit must be prepared by a county installer licensee, certified soil scientist, professional engineer, professional geologist or licensed surveyor, subject to listed exceptions.
    • Lot-specific and dimensional conditions are not stated in the cited passages; the chapter's exceptions were not fully read.
    “no site activity undertaken for the erection of any structure to be served by a septic system may be initiated prior to obtaining a septic permit.”
  • Subdividing landRegulated (with conditions)

    Division of land into building lots in unincorporated St. Joseph County, including Olive township; the county page says the City of South Bend processes applications only inside South Bend's incorporated limits.

    • Subdivision applications are filed by a land surveyor and reviewed by Area Plan Commission staff, then approved or denied by the plat committee.
    • A registered land surveyor must be involved in preparing, representing and certifying the plat.
    • The plat committee may approve a subdivision only if it meets the subdivision regulations.
    • Lot splits that do not create building lots are not addressed by this page; the subdivision regulations text itself was not opened.
    “local ordinances require that a property be subdivided when a parcel or portion of land is intended for sale or lease”

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