Do you need a building permit in the Village of Matherville, IL?
We could not confirm the Village of Matherville’s building-permit requirement, fee schedule, inspection sequence or certificate-of-occupancy requirement; request project-specific answers from Village Hall before starting work.21011 Illinois places building-permit administration with the applicable local government.2 Illinois statewide baseline building-code requirements took effect in 2025, so an unanswered local permit question does not mean construction is exempt from building standards.12 Ask Village Hall which code and local amendments apply to the proposed home.13
Does the Village of Matherville have zoning for RVs and tiny homes?
The Village of Matherville has residential, commercial, manufacturing and mobile-home-park zoning districts.1 Matherville’s district list distinguishes general residential from multiple-dwelling residential uses; the existence of a mobile-home-park district does not establish permission for a manufactured home on any residential parcel.5 We could not confirm Matherville’s RV occupancy, temporary camping, tiny-home, accessory-dwelling, minimum lot size or setback rules; ask Village Hall for the parcel’s district and the operative use and dimensional requirements before buying.5 Request a separate answer for temporary occupancy during construction and permanent occupancy.1
How do septic permits work inside the Village of Matherville?
Mercer County Health Department handles private onsite wastewater applications inside the Village of Matherville.3 Construction or repair requires an application, soil report and permit fee; the published fees are $200 for contractors and $600 for homeowner installation, and the permit is valid for 1 year.4 An onsite soils evaluation determines soil suitability and system sizing.14 Surface-discharging systems also require an Illinois EPA NPDES permit.4 Obtain plan approval before construction and notify the applicable health authority at least 48 hours before work begins.15
What are the steps for building a home in the Village of Matherville?
- Ask Village Hall to identify the Matherville parcel’s zoning district and confirm that the proposed residential use meets that district’s requirements.5
- Request the village’s building-permit, inspection and occupancy requirements before committing to a construction schedule.21011
- For a subdivision, resolve sewer access with the village: where public sanitary sewer is reasonably accessible, subdividers must connect or provide for connection and a village-board-approved system accessible to each lot.7
- If the project uses private septic, arrange the soils evaluation and submit the application, report and fee to Mercer County Health Department before construction.1415
What should you check before buying in the Village of Matherville?
Keep village land-use approval separate from private sewage approval: Matherville has its own zoning, while Mercer County Health Department handles private septic applications.13 We could not confirm a Matherville private-well permit rule; ask the health department about the proposed water source.3 An Illinois owner-occupant plumbing exemption is conditional and does not remove local plumbing-permit or inspection requirements.89 For land outside village limits, use the Mercer County guide: the county zoning resolution divides land outside incorporated municipalities into districts.16
