Unincorporated Fulton County, Illinois requires a zoning permit before construction, formerly called a building permit, but the county describes it as a land-use permit rather than a full building-code inspection permit1. County zoning applies, and well or septic permit numbers must be secured before the zoning permit can issue23. Septic permits and inspections go through the Fulton County Health Department45.

Do you need a building permit in Fulton County, Illinois?
Unincorporated Fulton County requires a zoning permit before construction; the county formerly called it a building permit, but it is a land-use and zoning approval rather than a full building-code inspection permit1. The application goes to the Zoning Office with parcel, ownership, proposed-use, location, sketch, address, and applicable well and septic information10. Illinois nevertheless has a statewide building-code baseline, so receiving a county zoning permit does not by itself answer every structural-code question11. The state does not issue building permits or conduct building inspections for privately funded construction; local governments handle any such administration1213. Ask Planning & Zoning which code-compliance documentation applies to your particular house before finalizing plans3.
Who issues permits in Fulton County, and how do you reach them?
Fulton County Planning & Zoning is the first stop for a project on unincorporated land: call (309) 547-0902, email [email protected], or visit 257 West Lincoln Street Lewistown, IL 615423. The office issues the county zoning permit and administers county zoning12. Fulton County Health Department Environmental Health handles septic and private-water permits at 309-647-1134, 700 East Oak Street1447. The Planning & Zoning office also serves as the county floodplain contact, and development in a special flood-hazard area must meet stricter construction rules153. For a driveway from a county road, contact Public Works & Highways at (309) 647-0351 before installing the entrance1617.
Does Fulton County, Illinois have zoning?
Fulton County administers zoning in unincorporated areas and publishes district-specific uses, lot dimensions, yards, and mobile-home standards26. Setbacks and building-height limits therefore depend on the parcel's district rather than one countywide number1819. Manufactured homes outside mobile-home parks face county conditions involving age, a HUD seal, skirting, anchors, utility connections, removal of running gear, and district-specific width or living-area standards9. A mobile home in the Agricultural Conservation district must have at least 500 square feet of living area, but that is not a general minimum size for every type of dwelling20. Before buying, give Planning & Zoning the parcel number and proposed use and ask for the district, setbacks, and whether special-use approval or a variance is needed3.
How do septic permits work in Fulton County?
A Fulton County Health Department permit is required before constructing, renovating, altering, or extending a private sewage disposal system4. The application requires the applicable fee, plans, soil information, owner information, and other information requested by the Health Officer, and the permit remains valid for one calendar year4. The installation cannot be covered or placed in service until the Health Officer has inspected it and approved it in writing5. About 38.6% of Fulton County soils are rated without severe limitations for a conventional septic drain field, so make soil and system feasibility an early purchase contingency21. County rules incorporate Illinois private-sewage statutes and codes22. Contact Environmental Health at 309-647-1134 before ordering a system or scheduling excavation14.
Can you live in an RV or tiny home in Fulton County?
Fulton County has not confirmed a general rule allowing long-term RV occupancy or temporary camping on private land. Ask Planning & Zoning whether the proposed use is permitted in the parcel's zoning district before buying or moving an RV onsite23. Fulton County also has not confirmed a specific tiny-home occupancy rule, and the published minimum of 500 square feet applies only to mobile homes in the Agricultural Conservation district rather than every dwelling20. A manufactured home is a separate category and must meet county requirements for its construction date, HUD seal, anchoring, utilities, running gear, and district dimensions9. Any allowed dwelling using private sewage still needs Health Department approval, and a new or modified private water supply needs its own permit47.
Building a home in Fulton County: the steps, in order
- Give Planning & Zoning the parcel number, site address, proposed use, and sketch so the office can identify the zoning requirements10.
- Determine whether the site lies in a special flood-hazard area, where development must satisfy strict construction rules15.
- Obtain the required well and septic permits from Environmental Health before the county zoning permit can issue347.
- Submit the zoning-permit application and supporting information to Planning & Zoning10.
- Apply to Public Works & Highways for an entrance from a county road; use the responsible township, state, federal, or municipal authority for other roads16.
- Leave the septic installation uncovered until it passes the required written inspection5.
- Contact Planning & Zoning when construction is complete so the office can issue the required certificate of occupancy or completion3.
What should you check before buying land in Fulton County?
Confirm the zoning district, allowed use, setbacks, and any special-use or variance path with Planning & Zoning before closing263. Make septic feasibility a contract contingency because only about 38.6% of Fulton County soils are rated without severe limitations for a conventional drain field21. Verify the private-water plan early because constructing, modifying, or deepening an individual or semi-private water supply requires a county permit7. Check mapped flood risk because special flood-hazard areas carry strict construction conditions15. Identify the road owner: a county-road entrance needs a county permit, while township, state, federal, and municipal roads go to their respective authorities16. Fulton County's effective property-tax rate is about 2.1%, with a median annual bill of about $2,1862324.
Watch-outs
- A Fulton County zoning permit is not the same as a full building-code inspection permit; ask Planning & Zoning what code-compliance documentation applies to the project13.
- Fulton County has not confirmed a general owner-builder exemption, so ask Planning & Zoning before assuming that acting as your own contractor changes any permit requirement83.
- Long-term RV living and tiny-home occupancy are not confirmed countywide rights; obtain a parcel-specific answer from Planning & Zoning before committing to either use23.
