Off-Grid Living in Pottawattamie County, Iowa

I've been digging into what it actually takes to live off-grid in Pottawattamie County, Iowa, and the short version is: this is a zoned county, which changes the picture compared to some Iowa counties that have no zoning at all.

Zoning. Pottawattamie County has adopted a full zoning ordinance, administered by the Planning & Development office, with districts for agricultural, residential, commercial, industrial, and slope-protection uses. A Board of Adjustment handles variances and conditional use requests. That said, I didn't find anything in county sources that specifically addresses "raw land occupancy," meaning just living on unimproved land without a permitted structure. I'd treat that as a gap to ask Planning & Development about directly, rather than assume it's fine.

Dwellings, tiny homes, RVs. The zoning ordinance sets lot and building standards by district, but whether a tiny house on a foundation counts as a legal dwelling, or whether an RV can be a permanent residence, isn't spelled out in what I found. This is exactly the kind of question where you want to call the Development Director's office before you buy land or a unit.

Building code. The State of Iowa, under Chapter 331 and Chapter 103A of the Code of Iowa, lets counties adopt and enforce the state building code. Pottawattamie County has done so, adopting current International Codes plus the state Mechanical and Electrical codes, enforced by the county's Building Safety Division in unincorporated areas. Incorporated towns inside the county run their own separate building departments.

Septic and composting toilets. Septic systems are regulated jointly by the State of Iowa (567 IAC Chapter 69) and the county (County Code Chapter 5.50), and you need a permit for new installs or repairs, administered through Pottawattamie County Public Health's Environmental Health Division. There's also a county assistance program helping rural homeowners replace failing systems. I found no county-specific carve-out for composting toilets, so assume the standard septic permit framework applies unless Environmental Health tells you otherwise.

Greywater and rainwater. Neither is directly addressed anywhere I could find, county or state. That's a real gap, not a green light, so check with Environmental Health before setting up a greywater system, and don't assume rainwater catchment is unregulated just because nothing prohibits it.

Wells. Private wells need a permit under state rules (567 IAC Chapters 38, 49, 82) and Iowa Code Chapter 137, administered locally by the county through the Iowa Well Information System. A licensed well driller does a site evaluation before you apply, and the county Planning Director's office does its own evaluation before the permit is issued.

Grid disconnection. Nothing explicitly bans going off-grid electrically, but your dwelling still has to clear the building code, septic permit, and well permit hurdles regardless of whether you're hooked to the power company.

Bottom line: Pottawattamie County is more regulated than a no-zoning county, so plan on real conversations with Planning & Development and Environmental Health before you commit to land.
