Unincorporated Livingston County has a building-permit process, and Regional Planning and Zoning publishes a Building Permit Application5. We could not confirm every project that requires a building permit; ask Regional Planning and Zoning about your proposed work1,5. Construction using an existing septic system may require Health Department clearance before the zoning office can issue the building permit; a noncompliant system must be upgraded when the proposed construction requires a building permit1. Illinois statewide baseline building codes have applied since 2025, and residential buildings also fall under the Illinois Energy Conservation Code9. Whether Livingston County has separately adopted a code is unconfirmed; ask Regional Planning and Zoning which codes, building inspections and occupancy approval apply5,10.
Who issues building permits in Livingston County, and how do you reach the office?

Does Livingston County have zoning, and what does that mean for setbacks and building height?
County zoning applies to unincorporated Livingston County.
County zoning applies to unincorporated Livingston County2,5. Pontiac, Dwight and Forrest have their own zoning11,12,13. Pontiac also issues its own building permits inside city limits14. The county's zoning and building-permit rules here apply to unincorporated land. Municipal zoning does not replace Livingston County Health Department septic approval for properties without public sewer3. Streator, which reaches into Livingston County from LaSalle County, also has city zoning; ask Livingston County Health Department to confirm septic jurisdiction for an address on the Livingston side15,16. In the R-A district, a single-family dwelling must have at least 720 square feet of ground-floor area if it is one story or 672 square feet if it has more than one story8. An R-A single-family lot must have at least 15,000 square feet with municipal water and sewer, 22,000 square feet with municipal or community water and an individual sewage system, or one acre with individual water and sewage systems8. The county's online code may not be current, and current setbacks and building heights remain unconfirmed5. Before buying or drawing a site plan, ask Regional Planning and Zoning to confirm jurisdiction, the parcel's current district, allowed uses, setbacks, height, lot size and any subdivision review5.
How do septic permits work in Livingston County?
The Livingston County Health Department handles local septic plan approval, permits and inspections for properties without public sewer; IDPH regulates private sewage disposal statewide.
The Livingston County Health Department handles local septic plan approval, permits and inspections for properties without public sewer; IDPH regulates private sewage disposal statewide3,4. The process starts with a completed application mailed with the applicable fees3. A new or altered system needs a Permit to Construct or Alter after plan approval, and a subsurface seepage field requires a soil investigation by an Illinois-licensed soil classifier or registered engineer2,17. The 2025 residential application lists a $150 permit fee and a $125 fee when a building permit is required, so the form itself is inconsistent; confirm the amount with the Health Department before filing2. Commercial systems use a separate application that requires daily-flow and sizing information, and construction is not permitted until the fee is paid18. An owner may install a system for the owner's personal residence; a second-party installer must be licensed by IDPH2,17. Inspection is required: owner-installers must notify the Health Department at least 48 hours before excavation and again before covering, and licensed contractors must give 48 hours' notice before covering for final inspection2. Countywide soil data rates 0% of soils as free from severe limits for conventional drain fields, so arrange soil work early19.
Can you live in an RV, tiny home or manufactured home on your land in Livingston County?
We could not confirm long-term RV occupancy, temporary camping or tiny-home occupancy rules for unincorporated Livingston County; ask Regional Planning and Zoning before planning to live on the parcel.
We could not confirm long-term RV occupancy, temporary camping or tiny-home occupancy rules for unincorporated Livingston County; ask Regional Planning and Zoning before planning to live on the parcel5. Illinois campground licensing rules do not answer whether one household may live in an RV on its own parcel20. Manufactured homes can be occupied under Illinois rules, but state installation standards apply in addition to local zoning, building, floodplain and utility requirements21. Because Livingston County administers a zoning ordinance, ask the Regional Planning and Zoning Office whether the parcel's district allows the proposed RV, tiny home or manufactured home, whether temporary occupancy during construction is allowed, and what dimensional or utility conditions apply5. Do not rely on a seller's claim that rural land is unrestricted; the county's published page confirms zoning but does not expose the full district schedule5.

- Schedule septic inspection: owner-installers must give at least 48 hours' notice before excavation and again before covering; licensed contractors must give 48 hours' notice before covering17.

Soils: countywide data rates 0% of Livingston County soils as free from severe limits for conventional septic drain fields, making an early site evaluation essential19.

Zoning: confirm the parcel's district, uses and dimensions with Regional Planning and Zoning because the online ordinance may not be current5. Access: IDOT requires a permit before work in a state-road right-of-way; ask the County Highway Department about county-road access7,24.

Watch-outs
- Livingston County requires building permits for some construction, but the available county material does not identify every covered project or the building inspections, occupancy approval and fees that apply; confirm those points with Regional Planning and Zoning1,5.
- The county's published zoning code may not be current, so get the parcel's current district and standards from Regional Planning and Zoning before relying on the online text5.
- Livingston County's owner-installer allowance applies only to a private sewage system for the owner's personal residence; it does not establish a general exemption from building requirements2.
- The Livingston County Health Department's septic application states both a $150 and a $125 permit fee, so ask which applies to your project before sending payment2,25.
