Off-Grid Living in Tazewell County, Illinois

I've been digging into what off-grid living actually looks like in Tazewell County, Illinois, and the short version is: this is not a "no rules" county. Unlike some rural Illinois counties that have never adopted zoning, Tazewell County has countywide zoning administered by its Community Development Department, plus a countywide Health Department that runs septic and well permitting. So a lot of the off-grid picture here is set locally, not just deferred to the state.

Zoning. In unincorporated parts of the county, the Tazewell County Zoning Ordinance (Title XV, Ch. 157) applies, with districts like A-1, A-2, and Conservation. Worth knowing: if your land sits within 1.5 miles of an incorporated city or village that has its own comprehensive plan, that municipality can claim extra-territorial jurisdiction over what you build. Always check with Community Development before assuming county rules alone apply.

Dwellings, tiny homes, RVs. The county's district regulations treat RVs mostly as temporary or seasonal uses, not permanent housing. A guest RV is capped at 60 days per year, and in agricultural or conservation districts an RV used "strictly for recreational purposes" can be allowed seasonally, but only with Health Department sign-off on water and sewage. I did not find a confirmed minimum square footage for tiny homes, so ask Community Development directly if that's your plan.

Building permits. The county requires a building permit, issued once the Community Development Administrator confirms your application meets code, and all required approvals and fees (unspecified here, confirm with the county) are in. New residential construction also needs Illinois Energy Conservation Code compliance (a REScheck report) and either septic approval or proof of sanitary district connection.

Septic and composting toilets. The Tazewell County Health Department issues septic permits, following Illinois Department of Public Health (IDPH) standards, including a required soil investigation. The Board of Health acts on applications within a set review window and permits are valid for a defined period, so confirm current timelines directly. Composting toilets fall under the state's IDPH baseline; no county-specific rule beyond that turned up.

Greywater and rainwater. I couldn't confirm any Tazewell-specific ordinance on either. Both default to the state's Illinois Plumbing Code framework under IDPH, with local health department input likely required case by case.

Wells. The county Health Department permits all well construction, repair, and pump installation, and requires wells and pumps be kept in safe condition by the owner. A specific permit fee applies, confirm the current amount with the Health Department rather than relying on any number you see elsewhere.

Utility disconnection. No outright ban on going off-grid electrically was confirmed, but building and habitability requirements effectively force a water/sewage solution, either an approved septic system or proof you've applied for sanitary district hookup.

Bottom line: Tazewell County is workable for off-grid living but expects you to go through its own zoning, building, septic, and well permitting rather than skip it. Call before you build.
