Do you need a building permit in Scott County, Illinois?

Scott County, Illinois appears not to require a county residential building permit in unincorporated areas, but the county does not publish a direct permit statement1. Illinois does not issue building permits, conduct building-code inspections, or issue occupancy permits for privately funded construction; the applicable county, city, or village decides whether each is required111213. Illinois's statewide building-code baseline took effect in 2025, but residential requirements still depend on whether the jurisdiction has adopted a code and on the purchaser-builder conditions for a jurisdiction without one14. Before ordering plans or materials, ask the Scott County Clerk whether an unincorporated parcel needs a building permit, building inspections, code review, or an occupancy certificate.

Who issues building permits in Scott County, and who handles septic?

Scott County does not list a separate building or zoning department12. Ask the Scott County Clerk to identify who decides building permits, building inspections, setbacks, and occupancy certificates for an unincorporated parcel; the county's published material does not resolve those questions12. Inside a city or village, ask that municipality about its building permits and zoning approval because Illinois leaves those requirements to the applicable local government11. Septic plan review does not move with municipal building or zoning authority: IDPH regulates private sewage-system installation, and local health agencies may review plans under local authority or as IDPH agents15. In Scott County, start septic and private-well work with the Health Department's Environmental Health division at 335 West Cherry St., Winchester, IL 62694, (217) 742-8203, or health@scottchd.com16.

Does Scott County have zoning?

Scott County does not list a planning or zoning department, but the county does not publish a clear statement confirming or denying countywide zoning2. The City of Winchester has separate municipal zoning administration, so land inside Winchester needs a city-specific answer3. Illinois law allows a county zoning district to establish building and setback lines outside municipalities that have their own zoning17. A county zoning district may also regulate building height, but the applicable ordinance must provide the actual limit18. We could not confirm a countywide minimum lot size, minimum dwelling size, setback, lot-coverage limit, or height limit. Ask the County Clerk to check the parcel's jurisdiction and any applicable ordinance before treating rural land as unrestricted2.

How do septic permits work in Scott County?

A new private sewage disposal system in Illinois needs septic plan approval before construction, including a septic-tank replacement or the removal or addition of a major component5. IDPH regulates installation, while local health agencies may review construction plans under a local ordinance or as an IDPH agent15. Scott County's first contact is the Health Department's Environmental Health division, which lists private sewage disposal among its services16. A person constructing, installing, repairing, or modifying a system must notify the Department or local authority at least 48 hours before work starts; covered portions may have to be uncovered if they prevent an inspection6. Only 33.6% of Scott County soils are rated without severe limitations for a conventional drain field, so make septic plan approval and any site evaluation a purchase contingency10. Alternative sanitation systems must meet the applicable state standards19.

Can you live in an RV or tiny home on your land in Scott County?

Illinois treats a recreational area as a campground when it maintains at least 3 tents, cabins, RVs, or other shelters for camping, or offers camping space for at least 10 people on at least 6 days in a year; a covered campground needs a state license with a $100 nonrefundable fee7. That rule does not answer whether one household may live in an RV on private land in unincorporated Scott County20. Ask the County Clerk before relying on an RV as temporary or permanent housing. Manufactured homes are subject to Illinois installation standards plus any applicable local zoning and covenants821. Scott County's zoning status is unconfirmed, so check a manufactured home's placement for the specific parcel2. We also could not confirm county rules for tiny-home occupancy or minimum dwelling size. The state plumbing exemption for a qualifying owner-occupant is not a general exemption from building rules22.

What are the steps to build a home in Scott County?

  1. Ask the Scott County Clerk to confirm whether a building permit, building inspection, county zoning approval, or occupancy certificate applies to the parcel12. Inside Winchester, check the city's zoning requirements; septic plan review still starts with the Scott County Health Department34.
  1. For possible floodway or floodplain work, send IDNR enough information to determine whether state authorization is required; that determination review is free, though this does not mean every authorization is fee-free23. Covered rural floodways use a 10-square-mile drainage-area threshold, and IDNR may require a permit anywhere in an undelineated floodplain; some minor work is covered by statewide permits24.
  1. Obtain septic plan approval through the Scott County Health Department before construction165.
  1. Give the Health Department or IDPH at least 48 hours' notice before septic work begins6.
  1. Obtain an IDOT driveway permit before work in a state-highway right-of-way9.

What should you check before buying land in Scott County?

Only 33.6% of Scott County soils are rated without severe limitations for a conventional septic drain field, so make the Health Department's site requirements a purchase contingency10. About 84.2% of the county is at a slope of 15% or less, while 15.2% is wooded; those countywide figures do not replace a parcel survey or site visit2526. Check flood maps and state permit jurisdiction before buying near a stream because qualifying floodway work requires state review27. A land division into 2 or more parts generally requires a survey and subdivision plat when any resulting part is under 5 acres, subject to statutory exceptions and possible supplemental county standards28. Scott County averages 39.2 inches of precipitation annually, and severe drought occurs in 2.2% of years2930. The effective property-tax rate is about 1.4%, the median annual bill is about $1,406, and the typical home value is about $89,662313233.

Watch-outs

  • Scott County does not publish a clear countywide building-permit or zoning answer; confirm both with the County Clerk before building12.
  • Long-term RV occupancy and tiny-home occupancy on private land remain unconfirmed; ask the County Clerk before planning around either use202.

Illinois rules that apply here

  • Building permitLimited

    Privately funded construction in Illinois; the State does not itself issue building permits, while any required permit is addressed by the applicable local government.

    • Permit requirements may be imposed and administered by the municipality, village, city, or county having jurisdiction.
    • The Illinois Capital Development Board states that statewide building codes became effective 1/1/2025, while local code officials remain the best source for project-specific answers.

    statewide building-code effective date: 2025-01-01

    “No. If any of these are required, they would be addressed by the unit of local government.”

      “No. If any of these are required, they would be addressed by the unit of local government.”
    • Not required — Issuance of building permits by the State of Illinois for privately funded construction.
      “No. If any of these are required, they would be addressed by the unit of local government.”
  • 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”

      “No. If any of these are required, they would be addressed by the unit of local government.”
    • Conditional — Statewide treatment of local plumbing permits and inspections for qualifying owner occupants performing plumbing work on a single-family residence.
      “Nothing contained in this Act shall prohibit any city, town, village, township or county from providing for a Plumbing Inspector or from requiring permits for the installation and repair of plumbing and collecting a fee therefor, but a city, town, village, township, or county that requires a permit for installation and repair of plumbing may not issue that permit without verification that the applicant has a valid plumbing license or that the applicant is the owner occupant of a single family residence that is the subject of the permit.”
  • Building code adoptedPartial

    New residential and commercial construction in Illinois, including Scott County, subject to whether the local jurisdiction has adopted a compliant building code and to the residential purchaser-builder conditions stated by the Capital Development Board.

    • Statewide building codes are effective 1/1/2025.
    • For residential buildings in jurisdictions that have not adopted a building code, where the home purchaser and home builder agree, new construction must use the current IRC or most recent preceding edition, or a municipal/county residential code within 100 miles of the home; the source identifies this requirement as effective 1/1/24 excluding Chapters IV and VII and cites 815 ILCS 670/15.
    • For residential buildings in jurisdictions that have not adopted a building code, where the home purchaser and home builder do not agree, new construction must use the current IRC; the source identifies this requirement as effective 1/1/24 excluding Chapters IV and VII and cites 815 ILCS 670/15.
    • For residential buildings in jurisdictions that have adopted a building code, local codes and amendments apply, and starting 1/1/25 local codes must regulate structural design at least as stringently as the IRC.
    • For commercial buildings in jurisdictions that have not adopted a building code, new or substantially improved buildings must comply with the listed state baseline codes, including the IEBC, IBC, NEC, Illinois Energy Conservation Code, Illinois Accessibility Code, Illinois Plumbing Code, and Fire Prevention and Safety Rules; non-state buildings must be inspected by a qualified inspector.
    • The Illinois Energy Conservation Code, Illinois Plumbing Code, and other listed state requirements may apply in addition to the residential or commercial structural-code requirements.
    • The Capital Development Board page states that its summary covers major construction codes only and that exceptions, exemptions, and other codes may apply.
    • Illinois municipalities and counties are not required to adopt building codes; if they do not adopt one, they are treated as non-building-code jurisdictions and section 10.09-1 of the Capital Development Board Act applies.

    statewide baseline effective date: 2025-01-01 · alternative municipal/county residential code distance: <= 100 miles (Available only for new residential construction in a jurisdiction without an adopted building code where the home purchaser and home builder agree.)
