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 rulesDoniphan County, KS
Zoning & raw-land occupancy
RestrictedDoniphan County has adopted countywide zoning administered by its Planning & Zoning Department, with districts including Agricultural, Residential-Outer, Mixed Use, Industrial, and Planned Overlay. This is a county-level rule, not a state mandate, so confirm your parcel's district before planning. source
Dwellings, tiny homes & RVs
Unclear - verifyNo official county document defines rules for tiny homes, RVs, or park models. Claims that the county is 'tiny-home friendly' come from non-official sources; ask Planning & Zoning about your specific district.
Building permits & codes
Varies locallyThe county's own FAQ says Doniphan has no adopted building code and requires no general construction inspections except for septic systems, but a permit is still required for most construction (not for roofing) per the county forms page. source
Septic & composting toilets
Generally allowedSeptic and wastewater permitting is handled not by the county directly but by a regional agency, Northeast Kansas Environmental Services (NEKES), operating under KDHE's statewide standards. source
Greywater reuse
Unclear - verifyNo county or NEKES page separately addresses greywater; it appears to fall under the same wastewater permitting as septic, but this is not confirmed. Ask NEKES directly.
Rainwater harvesting
Generally allowedNo county ordinance restricts rainwater harvesting. The state's general domestic-use exemption under the Kansas Water Appropriation Act appears to apply with no added county restriction found.
Private wells & water rights
Varies locallyWell construction and abandonment follow state rules (K.A.R. 28-30) enforced through KDHE-licensed contractors. Whether Doniphan County requires an additional local well permit is not confirmed; check KDHE's county permit list. source
Living disconnected from utilities
Unclear - verifyNo ordinance requiring connection to public utilities was found, and the absence of a general building code makes a hookup mandate seem unlikely, but this isn't explicitly confirmed. Ask Planning & Zoning to be sure.
