Unincorporated Marshall County, Illinois requires a county building permit before construction begins, and the Zoning department provides the application1. County zoning applies, with township zoning maps available for parcel research23. Private septic permits go through the Bureau, Putnam & Marshall Health Department rather than the county Zoning office4.

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

Yes. Unincorporated Marshall County requires a Building Permit before construction of a building, structure or addition begins, and the county Zoning department publishes the application1. Qualifying structures used for agricultural purposes in an agricultural district follow a narrower written-notification process showing setback lines rather than the ordinary application requirements1. Illinois does not issue building permits for privately funded construction; any permit requirement is administered by the applicable local government10. Illinois has also required statewide baseline building codes since January 1, 2025, while locally adopted codes must comply with the state framework11. Ask Marshall County Zoning which code, plan documents and inspections apply to the specific project because the county-specific code adoption and inspection stages were not confirmed12.

Who issues Marshall County building permits, and how do you reach the office?

Marshall County Zoning is the first stop for building-permit and land-use questions in unincorporated Marshall County, and its official page provides the Application-for-Building-Permit5. The office is at 552 State Route 26 in Lacon, and it can be reached at 309-246-6401 or [email protected]5. Variances, special uses and amendments that cannot be processed administratively go to the Zoning Board of Appeals, so applicants should contact staff to confirm the hearing date and filing deadline5. County permit fees, required inspection stages and any certificate of occupancy requirement could not be confirmed; ask Zoning for the current fee and project checklist before submitting.

Does Marshall County have zoning?

Yes. Marshall County has a county Zoning Ordinance, a Zoning Administrator and a Zoning Board of Appeals2. The county publishes zoning maps by township, but warns that map information may not include the most recent updates, so use the map to identify a likely district and then confirm it with County Zoning3. Setbacks and building-height limits are district-specific rather than one statewide measurement78. The county materials available here did not confirm a single minimum lot size, minimum dwelling size or lot-coverage limit for every parcel. Incorporated municipalities may have different land-use rules, so ask the municipality rather than Marshall County Zoning when the property is inside city or village limits.

How do septic permits work in Marshall County?

The Bureau, Putnam & Marshall Health Department reviews plans and issues permits for private sewage disposal systems, offers consultations before construction and inspects systems before use13. Illinois requires plan approval from the Department or local authority before construction of a new private sewage disposal system begins14. The rule treats replacement of a septic tank, addition or removal of a major component, and an absorption-field change of at least 25 percent as new-system work14. The installer must notify the Department or local authority at least 48 hours before construction, installation, repair or modification begins15. Only 14.6 percent of Marshall County soils are rated without severe limits for a conventional septic drain field, so make the site evaluation an early purchase contingency rather than assuming a standard system will fit16.

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

We could not confirm a Marshall County rule allowing long-term residential RV occupancy or tiny-home occupancy on a private parcel. County zoning still applies, and the zoning district controls local land-use questions, so give Marshall County Zoning the parcel number and describe the proposed dwelling and duration before buying or moving a unit onto the land25. Illinois campground rules address licensed campgrounds and temporary RV parking in that setting; they do not establish permission to occupy an RV as a residence on a private lot17. Manufactured homes have a separate statewide framework: installation may be performed by an Illinois-licensed installer or the homeowner and must follow the manufacturer's instructions or the state installation code, while local zoning, building and floodplain requirements may still apply18.

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

  1. Ask Marshall County Zoning to confirm the parcel's district and the applicable use, setback and height rules27.
  2. If the site needs septic, obtain health-department plan approval before beginning system construction14.
  3. If the site needs a private well, obtain the required permit from IDPH or the approved local health department before well work starts19.
  4. File the county building-permit application with Marshall County Zoning and ask which plans, fees and inspections apply15.
  5. Obtain a Highway Department permit before creating an entrance or doing other work in county right-of-way20.
  6. For a driveway on a state-maintained road, obtain the separate IDOT right-of-way permit before work begins21.
  7. Give the health authority at least 48 hours' notice before septic work begins and arrange the pre-use inspection1513.

What should you check before buying land in Marshall County?

Confirm the zoning district and current township map with Marshall County Zoning before relying on a listing's description3. Put septic feasibility near the top of due diligence because only 14.6 percent of county soils are rated without severe limits for a conventional drain field16. Verify legal access too: a new entrance in county right-of-way needs a Highway Department permit, while access from a state-maintained road follows the IDOT permit process2021. New private wells require a permit and plan review before construction9. For price context, the typical home value is $143,081, farmland averages $10,448 per acre, and the median property-tax bill is $2,743 a year at a 2 percent effective rate22232425.

Watch-outs

  • Long-term RV living and tiny-home occupancy were not confirmed; ask Marshall County Zoning about the specific parcel and proposed use before purchase25.
  • A county entrance permit is required for work in county right-of-way, while a state-road entrance follows a separate IDOT permit process2021.
  • Only 14.6 percent of Marshall County soils are rated without severe limits for a conventional septic drain field, so obtain a site-specific evaluation early16.
