Off-Grid Living in Pike County, Illinois

I've been digging into Pike County, Illinois for anyone thinking about building or living off-grid out here, and the honest headline is: it's workable, but you'll be making a lot of phone calls before you break ground.

Zoning is county-administered by the Pike County Zoning Administrator, but here's the catch: 13 municipalities in the county have their own zoning ordinances that override the county's rules inside town limits, and all but one township (Greene) has adopted its own zoning too. So whether you're free to just buy raw land and sit on it, or build, depends heavily on whether you're in unincorporated county territory or inside one of those local jurisdictions. Don't assume, call the Zoning Administrator's office and ask specifically about your parcel.

Dwellings, tiny homes, and RVs are handled case by case. From what I found in one residential zoning district's text, living in an RV requires a special use permit through the Planning and Development Department, tied to a "certified hardship" process, followed by a separate building permit for the temporary RV installation. You'll also need to submit water/well and septic plans to the Health Department before that's approved. I could not confirm any minimum dwelling size rule or whether Pike County has adopted an Appendix Q tiny-house provision, so ask directly.

Building permits do exist at the county level, since the Health Department's Environmental Health page links to a building permit application. I wasn't able to confirm which building code edition the county has adopted, so that's a question for the Zoning or Building office directly.

Septic is well documented: Pike County requires a permit for all new septic installations or repairs, under a formal ordinance (Pike County On-Site Sewage Disposal System Ordinance, 2020-A&B). Installation is generally required to be done by a licensed installer, though homeowners may self-install after contacting the Health Department's Environmentalist about the procedure. A fee applies, payable to the Health Department.

Greywater and rainwater harvesting are both unclear. I found no Pike County-specific ordinance addressing either one. That's not the same as "prohibited," it just means the county hasn't published clear guidance, so ask the Health Department's Environmental Health division how they'd classify a greywater system.

Wells are permitted and regulated jointly by the state (Illinois Department of Public Health) and the Pike County Health Department, which is the local approving authority. State rules require a permit before construction, modification, or sealing of a well, and require the driller to notify the health department a couple of days before work starts.

Full utility disconnection (no grid power, no municipal water/sewer) isn't explicitly addressed either way in what I found. The RV/special-use process suggests the county does want to see an approved water and septic plan before signing off on occupancy for at least some dwelling types, which acts as a practical floor even without a blanket "must connect" ordinance.

Bottom line: Pike County isn't hostile to off-grid living, but a lot of the fine print sits in documents that aren't fully public online. Call before you buy or build.
