What should you check before buying land in Perry County?

Verify jurisdiction, zoning district, residential use, lot area and the buildable envelope.

Verify jurisdiction, zoning district, residential use, lot area and the buildable envelope2. Confirm County Board approval before buying a newly created parcel that falls within the subdivision rules12. Only about 3.2% of county soils are mapped without severe limitations for conventional drain fields, so make sewage feasibility a purchase contingency13. Check permanent street access, floodplain constraints and private-well permitting before placing improvements2,3,14.

Watch-outs

  • Zoning compliance comes before the building-permit application1.
  • A private sewage system cannot be covered or used before inspection and written approval3.
  • An owner may apply for a permit, but we could not confirm a general owner-builder exemption from Perry County's rules; Illinois provides only a limited plumbing exception for qualifying owner-occupants1,4.

Illinois rules that apply here

  • Owner-builder exemptionConditional

    Owner occupants or lessee occupants of single-family residences, and owners of single-family residences under construction for their own occupancy, performing plumbing planning, installation, alteration, or repair in Illinois.

    • The exemption is limited to plumbing work on the specified single-family residence; the cited statute does not establish a general owner-builder exemption for all construction trades or a statewide exemption from building permits.
    • The plumbing must comply with the minimum standards in the Illinois State Plumbing Code.
    • The plumbing is subject to inspection by the Illinois Department of Public Health or by the local governmental unit if it retains a licensed plumber as inspector.
    • The owner, owner occupant, or lessee occupant may not employ anyone other than a plumber licensed under the Illinois Plumbing License Law to assist.
    • An occupant must have taken possession of and be living in the premises as their bona fide sole and exclusive residence, or, for a residence under construction, expect to take possession and live there as that residence, with current intent to live there for at least 6 months after completion of the plumbing work or, for a residence under construction, at least 6 months after completion of construction.
    • Failure to possess and live in the premises as a sole and exclusive residence for 6 months or more creates a rebuttable presumption that the required intent was lacking.

    minimum occupancy period: >= 6 months (After completion of plumbing work; for a residence under construction, after completion of construction.)

    “Nothing herein contained shall prohibit the owner occupant or lessee occupant of a single family residence, or the owner of a single family residence under construction for his or her occupancy, from planning, installing, altering or repairing the plumbing system of such residence”
