The local rulesShelby County, IA
Zoning & raw-land occupancy
Varies locallyShelby County has adopted countywide zoning under Iowa Code Chapter 335; the Board of Supervisors can regulate lot use, density, setbacks, and even restrict tents/trailers as dwellings. Applies even on unincorporated land. source
Dwellings, tiny homes & RVs
Varies locallyCounty zoning ordinance 2006-6 sets district standards and gives the Board of Adjustment discretion over nonstandard uses; specifics on tiny homes or long-term RV occupancy are not confirmed on official pages, so ask the Zoning Administrator.
Building permits & codes
Varies locallyThe county Zoning Administrator processes construction and conditional use applications, but which state building code edition applies, and any off-grid exemptions, is not confirmed from official pages. source
Septic & composting toilets
Generally allowedShelby County Environmental Health requires a permit before septic construction, sized per state code by soil and bedroom count, with a percolation test; systems are inspected at time of property transfer. source
Greywater reuse
Unclear - verifyNo official Iowa DNR or Shelby County page spells out greywater reuse rules. Not confirmed, ask Shelby County Environmental Health since it may be handled under septic permitting. source
Rainwater harvesting
Unclear - verifyNo official state or county page confirms rainwater harvesting rules one way or the other. Not confirmed, ask Environmental Health or Planning & Zoning.
Private wells & water rights
Generally allowedShelby County permits and inspects new private wells, requires a state-certified well driller, and offers free water testing plus a DNR-funded well grant program. source
Living disconnected from utilities
Varies locallyNo outright county ban on disconnecting from utilities was found, but occupied dwellings still must meet zoning, septic, well, and a county radon-resistance construction requirement adopted in 2005. Certificate of occupancy for fully off-grid homes is not confirmed, ask Planning & Zoning. source
