Building permits, zoning and septic in Stronghurst Township, Illinois

Stronghurst Township, Illinois has no confirmed township-wide building-permit answer; the Village of Stronghurst issues building permits within its jurisdiction.1 The village zoning code applies inside the village and within its stated surrounding area, rather than establishing township-wide zoning.2 In Henderson County, private septic systems and new wells go through the Henderson County Health Department.34

Do you need a building permit in Stronghurst Township, IL?

For Stronghurst Township land within the Village of Stronghurst’s jurisdiction, the village building-permit office says a completed building permit must go to the Zoning Committee for approval before work starts.1 We could not confirm a township-wide building-permit requirement outside that jurisdiction; ask Village Hall to identify the boundary before choosing an application route.1 Illinois does not issue building permits for privately funded construction; any required building permit is handled by the applicable local government.7 Illinois statewide building-code requirements took effect in 2025, so an unconfirmed local permit requirement is not an exemption from applicable building standards.8

Who handles building permits in Stronghurst Township?

The Village of Stronghurst Building Permits/Zoning Board issues village building permits, reviews building plans, conducts construction inspections and issues certificates of occupancy.1 Village Hall gives the building-permit contact as 309-924-1525.1 For a project within village jurisdiction, download the building-permit application from the village page, complete the form and return it to Village Hall.1 Ask Village Hall which review and inspection steps apply to the proposed project and whether the parcel is within village jurisdiction.1 Private septic-system approval remains with the Henderson County Health Department rather than the village building-permit board.3

Does Stronghurst Township have zoning or farm-building exemptions?

The Village of Stronghurst zoning code states that its provisions apply throughout the village and within its surrounding jurisdiction; that rule is not a township-wide zoning ordinance.2 Ask Village Hall to locate the parcel against that jurisdiction before relying on village zoning for a Stronghurst Township purchase.1 Agricultural land and agricultural buildings in the village zoning jurisdiction receive an exemption from the title’s restrictions, but agricultural buildings must still conform to building or setback lines and may require a building permit.5 The farm exemption therefore does not establish blanket permission to place a barn wherever desired.5

How do septic permits and wells work in Stronghurst Township?

New or renovated private sewage systems in Stronghurst Township require Henderson County Health Department plan review before construction, with a site evaluation and inspection.39 Illinois also requires approval before private sewage-system construction and notification to the Department or local authority at least 48 hours before work begins.10 New private wells in Stronghurst Township require county health department plan review and site evaluation before a construction permit is issued.4 For an existing rural property, the health department offers septic-system inspections and private-well evaluations with sampling upon request; ask for those services before committing to a purchase.1112

Can you live in an RV or tiny home in Stronghurst Township?

We could not confirm township-wide permission for residential RV occupancy, tiny homes or temporary camping; for land within the village zoning jurisdiction, start with Village Hall and describe the intended use before placing a structure.21 Village zoning applies to its stated territory, so the absence of a confirmed township-wide answer does not establish an unrestricted parcel.2 Illinois allows specified alternative human-waste arrangements subject to technical requirements, but other domestic wastewater must still go to a conventional private sewage disposal system.13 Ask the Henderson County Health Department how an RV or tiny-home proposal would satisfy wastewater requirements before treating a compost toilet as a complete sanitation solution.1413

Building in Stronghurst Township: what should you check first?

Start by asking Village Hall whether the Stronghurst Township parcel falls within the village’s zoning jurisdiction and which village building approvals apply.21 Arrange private septic plan review and site evaluation with the Henderson County Health Department before construction, and obtain a new-well permit if the project needs a private well.34 Ask IDNR about proposed work in a regulated floodway; local floodplain requirements may also apply.15 A new driveway onto an Illinois state highway requires IDOT approval before work begins.16 For land outside Stronghurst Township, consult the Henderson County guide for the county’s septic and well responsibilities.1718

Watch-outs

  • The Village of Stronghurst’s zoning jurisdiction is not the same as Stronghurst Township; verify the parcel boundary with Village Hall.21
  • Agricultural buildings in the village zoning jurisdiction must follow building or setback lines, and a building permit may still be required.5
  • Illinois’s owner-occupant plumbing exemption does not establish a general owner-builder exemption from building permits or inspection requirements.619
