Off-Grid Living in Tama County, Iowa

I've been digging through Tama County, Iowa's official pages to see what off-grid living actually looks like here, and the short version is: this is a zoned county, so you're dealing with real permitting requirements, not a blank slate.

Zoning. Unlike some rural Iowa counties that have no zoning at all, Tama County adopted a countywide Zoning Ordinance under the authority of Iowa Code Chapter 335, administered by the County Zoning Office in Toledo. The ordinance requires zoning certificates for development and splits uses into those permitted by right and those needing a special exception from the Board of Adjustment. If you're inside an incorporated town, though, that town's own code applies instead, not this county brief. I did not find anything in the county's public materials that treats "just living on raw land" (vehicle, yurt, etc.) as its own category, so I'd assume the standard zoning/building process applies.

Dwellings, tiny homes, RVs. This is genuinely murky. The county's zoning ordinance text is posted online, but I couldn't find an official excerpt spelling out minimum square footage or a clear rule on RVs or tiny houses as permanent residences. Iowa Code §335.30 does limit how counties can regulate HUD-code manufactured homes on agricultural land, which matters if that's your plan. For anything else, call the Zoning Office before you buy or place a unit.

Building permits. The Zoning and Planning Administrator issues both zoning permits and building permits for unincorporated Tama County. Iowa's statewide Chapter 103A Building Code sets the floor, and factory-built structures (manufactured/modular homes) get separately licensed and inspected by the state Department of Inspections, Appeals and Licensing.

Septic and wells. Both require permits through the county's Environmental Health/Sanitarian office, currently under Environmental Health Officer Chris Behrens. Septic systems need site analysis and soil sampling; well construction has its own "Non-Public Water Well Construction Permit." Health board minutes show these permits are actively issued, so this isn't a rubber-stamp process, but it is a normal, functioning one.

Greywater and rainwater. I found nothing in county or Iowa DNR materials that specifically addresses either one. That's a genuine gap in the public record, not a green light, so ask the Sanitarian's office directly before setting up a greywater or catchment system.

Utilities. No outright ban on disconnecting from the grid, but the zoning/building certificate process and the county's septic and well permitting are still the practical gatekeepers. There's no separate "off-grid permit," but you can't skip the underlying building, septic, and well rules just because you're not hooking up to utilities.

Bottom line: Tama County is workable for off-grid living, but it runs through real permits, not around them. Call before you build.
