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

Yes. Unincorporated Macon County, Illinois requires a building permit for new construction and remodeling outside incorporated cities, villages and towns1. The zoning code specifically requires a permit for any building or structure longer than 10 feet on any side and for any addition1. The county reviews applications, issues permits and enforces the International Building Code11. Illinois also sets a statewide building-code baseline that took effect in 2025, including for jurisdictions without a locally adopted code12. Apply before work starts: unpermitted work is illegal, and a late application doubles the permit fee1. Land and structures used solely for agriculture have a conditional permit exemption, but agricultural structures must still follow building or setback lines8.

Who is the Macon County Planning & Zoning Department, and how do you reach them?

Macon County Planning & Zoning reviews applications and issues building permits for new construction and remodeling in unincorporated Macon County11. Reach the department at (217) 424-1466, or visit 141 South Main Street, Suite 501, Decatur, Illinois13. The county publishes a fee schedule and a required-inspections document, but the available material does not provide the project fees or inspection stages; ask the department for both when applying914. A local inspector oversees permitted work, and unpermitted work can cause trouble when the property is sold13. We could not confirm an owner-builder exemption, so ask whether the owner may pull the permit and perform the proposed work15.

Does Macon County have zoning?

Yes. Macon County Planning & Zoning administers zoning, subdivision, floodplain and stormwater ordinances in unincorporated Macon County5. The county also regulates subdivision plats and development, including approval and filing steps and private-sewage planning for proposed subdivisions16. Lot size and building height depend on the zoning district1718. In the A1 Agricultural District, permitted uses generally require at least 10 acres, with limited routes for certain single-family homes on qualifying tracts of at least 1 acre17. Ask Planning & Zoning to identify the parcel's district and confirm allowed uses, setbacks and height limits before designing. Incorporated cities, villages and towns have separate jurisdiction5.

How do septic permits work in Macon County?

The property owner must obtain a Macon County Health Department permit before constructing or repairing a private sewage system7. A permit may go to an Illinois-licensed installer or a homeowner installing the homeowner's own residential system, and the county acts on applications within 14 days7. The permit lasts 6 months if construction has not begun7. Environmental Health inspects septic-system construction and installation, and Illinois requires plan approval from IDPH or the local authority before a new system is built, with at least 48 hours' notice before work begins1920. The county's ordinance expressly requires inspection of septage disposal sites; the reviewed text does not state that every private system installation must be inspected21. These septic rules apply to every address in Macon County, including lots inside incorporated places7. Only about 2.6% of Macon County soils rate free of severe limits for a conventional drain field, so establish wastewater feasibility before fixing the house site22. Reach Environmental Health at (217) 423-6988, extension 1134, or 1221 E. Condit St., Decatur, Illinois23.

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

Macon County allows manufactured homes as residential dwellings in the RMH1 Single Family Residential District, alongside site-built and modular homes, subject to district height, area and parking rules10. That does not establish permission on every parcel, so have Planning & Zoning verify the zoning district before buying or placing a manufactured home. We could not confirm a separate county rule for tiny-home occupancy or a minimum dwelling size; ask Planning & Zoning how the proposed unit would be classified and which district standards apply. Illinois campground licensing rules govern campgrounds, not living in an RV on one's own parcel24. We also could not confirm whether an RV may serve as a residence on private rural land in unincorporated Macon County; ask Planning & Zoning before relying on an RV for temporary or long-term housing25.

Building a home in Macon County: the steps, in order

  1. Confirm the parcel's zoning district, allowed use, lot standard and height limit with Planning & Zoning61718.
  2. Check floodplain constraints before fixing the building site because regulated development needs a county permit26.
  3. Apply to Environmental Health for the septic permit and, if needed, the private-well permit before either system is built74.
  4. Submit building and zoning applications before construction begins; applying late doubles the building-permit fee11.
  5. Schedule the county's required building inspections and Environmental Health's septic installation inspection1419.
  6. Obtain the certificate of occupancy before occupying a new building or addition27.

What to check before you buy land in Macon County

Confirm the parcel's zoning district, lot standard and allowed use with Macon County Planning & Zoning before buying617. Ask whether the building area is affected by the county floodplain ordinance26. Have Environmental Health evaluate wastewater feasibility because only about 2.6% of Macon County soils rate free of severe limits for a conventional drain field22. A private water well requires county plan review and a permit4. If the parcel touches a state-maintained highway, IDOT requires a permit before right-of-way work, including an access driveway28. The median property-tax bill is about $2,560 a year at an effective rate near 2.1%2930.

Watch-outs

  • Applying for a Macon County building permit after work has already begun doubles the permit fee, so apply before you start9.
  • Macon County's agricultural exemption applies only while land and structures are used solely for agriculture, and agricultural structures must still follow building or setback lines8.
  • Macon County's own pages do not address whether a recreational vehicle may serve as a residence on private rural land, so confirm with Planning & Zoning before assuming it is allowed25.
