Zoning, building permits and septic rules in Byron Township, Illinois

Rules another office applies inside Byron Township

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

  New residential construction on unincorporated land inside Byron township

  • Permits are generally required for most construction on residentially used land, including new homes, additions, decks, porches, patios, detached buildings such as sheds, and pools.
  • Construction may proceed after the permit is issued, so the status is conditional.
  • The City of Byron and other incorporated areas are outside this county rule.

  “on residentially used land, for example, permits are generally required for most construction including new homes”

• InspectionsRequired

• Minimum lot sizeDistrict specific (with conditions)

  Resulting parcel when an existing farm dwelling in an AG-1 district, built before March 24, 1992, is separated (split off) on unincorporated land in Byron township. This is a split-off condition, not a general minimum lot size for new lots.

  • A plat of survey is required, prepared by an Illinois-licensed professional land surveyor.
  • If the existing dwelling is at least 300 ft from the road, an access strip at least 20 ft wide may be used; the interior parcel must still meet the minimum lot size (excluding the strip) and the 150 ft width requirement.
  • The plat of survey must be presented to the zoning administrator for review and approval before recording and sale or transfer.
  • Source states that the interior parcel must meet the minimum lot size and width requirement, and that yard area requirements must be met.

  minimum lot area of resulting parcel: >= 1 acre (AG-1 split-off of an existing farm dwelling built before March 24, 1992 (43,560 square feet)) · minimum road frontage of resulting parcel: >= 150 feet (AG-1 split-off of an existing farm dwelling)

  “the resulting lot/parcel must comply with the illinois plat act 765 ilcs 205, be at least one (1) acre in area (43,560 square feet) and have at least 150′ of road frontage.”
