43.0339, -92.4952 · 1,070 ft elevationRead this before you act on anything below. This is my researched starting point for Chickasaw County, IA, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.
The local rulesChickasaw County, IA
Zoning & raw-land occupancy
Varies locallyChickasaw County has no countywide zoning ordinance, so raw land in unincorporated areas is mainly subject to the county's subdivision and floodplain rules through the Land Use Office. If your parcel is inside New Hampton or within its two-mile fringe, that city's own zoning and planning department takes over, so check location carefully before assuming county rules apply. source
Dwellings, tiny homes & RVs
Unclear - verifyI couldn't find a Chickasaw County ordinance specifically addressing tiny homes, RVs, or manufactured housing siting on raw land. With no countywide zoning, this likely falls to individual towns/townships or defaults to Iowa's general manufactured-housing statute, so I'd confirm with the Land Use Office or the relevant town before setting up a dwelling. source
Building permits & codes
Unclear - verifyIowa only requires cities of 15,000+ residents to adopt the State Building Code, and no Chickasaw County page describes a countywide residential building-permit process, the County Engineer only permits road/right-of-way work. State inspectors step in only where a local jurisdiction has adopted the state code, so I'd ask the Land Use Office or your town directly what applies to your build. source
Septic & composting toilets
RestrictedSeptic and alternative wastewater systems are regulated in Chickasaw County through the Environmental Health Department's Waste Water Systems program, which issues permits and may require ongoing maintenance contracts on certain systems, consistent with Iowa DNR oversight. Composting toilets aren't separately addressed, so I'd check with the County Sanitarian before relying on one instead of a permitted system. source
Greywater reuse
Unclear - verifyI found no Chickasaw County or Iowa DNR page that specifically addresses residential greywater reuse; it seems to fall under the general onsite wastewater program without dedicated rules. Ask the county Sanitarian in the Environmental Health Department before installing a separate greywater system.
Rainwater harvesting
Unclear - verifyNo Chickasaw County ordinance or Iowa DNR rule was found that explicitly permits, restricts, or requires a permit for rainwater catchment. I'd still confirm with the county Environmental Health office before setting up a system, especially if you plan to use it for drinking water.
Private wells & water rights
Generally allowedPrivate wells serving a single household are permitted through the Chickasaw County Environmental Health Department, which issues Water Well Construction Permits and handles required post-construction water testing under state rule (567 IAC Ch. 49), working within Iowa's statewide well program (IWIS). Expect a required water sample window after construction as part of the process. source
Living disconnected from utilities
Varies locallyI found no Chickasaw County ordinance that bans living disconnected from the grid, but going off-grid doesn't exempt you from the county's well and septic/wastewater permitting requirements through Environmental Health. So you can disconnect from utilities, but you'll still need permitted water and waste systems in place. source
