Off-Grid Living in Wilson County, Kansas
Wilson County, Kansas has countywide zoning and its own 2011 Sanitary Code, so off-grid builders need a Zoning Permit and a septic permit through the County Health Department, not just state-level compliance. Wells and rainwater fall back to Kansas state rules since no county-specific ordinance was found for either.
Is it legal to live off-grid in Wilson County, Kansas?
There is no outright ban on living off-grid in Wilson County, Kansas - it is legal but regulated. Zoning and land use are restricted, putting a cabin, tiny home, or RV on raw land is set locally and vary by area, and building permits are restricted. Plan around septic/wastewater (restricted) and disconnecting from utilities (not clearly documented online, so confirm it locally). Because these rules are set locally, confirm the specifics with Wilson County before you buy land or build.

I've been digging into Wilson County, Kansas for anyone thinking about building or living off-grid out there, and here's the honest picture based on what the county and state actually publish.
Zoning. Unlike a lot of rural Kansas counties, Wilson County is not "unzoned." The county's Zoning Regulations, administered by the County Zoning Administrator, require a Zoning Permit before you build, rebuild, or change land use. If you want a non-farm residence, the county sets a five-acre minimum lot size; other non-farm uses need a smaller minimum. Straight agricultural use is exempt from zoning as long as it's outside a floodplain. Variances and conditional uses go to the Planning Board, which doubles as the Board of Zoning Appeals.
Dwellings, tiny homes, RVs. The zoning rules spell out what's a permitted residential structure: single-family homes, earth-sheltered homes, modular homes, and manufactured homes on permanent perimeter foundations. That wording suggests an RV or a tiny home not on a permanent foundation may not qualify as permitted, and could need a conditional-use approval instead. This isn't fully spelled out in what I could find, so if that's your plan, call the Zoning Administrator before you commit to a site.
Building permits. The county's Zoning Permit and Occupancy Certificate process is the mechanism that governs new construction. I did not find a standalone county building code (like an adopted IRC) on official pages, so treat that as unconfirmed rather than assume there isn't one.
Septic. Wilson County has its own Sanitary Code (adopted 2011, on file with KDHE), enforced by the County Health Department's Sanitarian, who issues septic installation, modification, and hauler permits. State minimum design standards from KDHE back this up. Composting toilets aren't clearly addressed in what I found for this county specifically, so ask the Health Department directly.
Greywater. I could not confirm Wilson County's specific greywater language. It's likely folded into the Sanitary Code's wastewater rules, but I couldn't read the exact text, so treat this as unclear and confirm with the Health Department.
Rainwater harvesting. Nothing suggests Wilson County restricts this beyond the Kansas state baseline, which allows it under the domestic-use exemption in the Water Appropriation Act.
Wells. No county-specific well ordinance turned up. Well construction runs through the state, KDHE's Water Well Contractor's License and Water Well Construction rules.
Off-grid utilities. I found no explicit rule requiring hookup to public utilities, but you'd still need to clear the Zoning Permit and Sanitary Code hurdles regardless of grid connection.
Bottom line: Wilson County is more regulated than people expect from rural Kansas. Call before you buy land or start building.
