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 rulesMarion County, KS
Zoning & raw-land occupancy
Varies locallyMarion County, Kansas has countywide zoning through its Planning, Zoning & Environmental Health Department, unlike many rural Kansas counties with no zoning at all. What's allowed on raw land depends on which district it's in (Ag, Rural Residential, Suburban Residential, Single-Family Residential, Floodplain, etc.), so confirm the district and permitted uses with that department before you buy or build. source
Dwellings, tiny homes & RVs
RestrictedThe county's Manufactured Home Code bars new placement of mobile homes and non-HUD-compliant manufactured homes, while HUD-compliant manufactured homes are treated like a regular single-family dwelling if sited per the rules. RVs are only addressed as accessory/temporary parking or storage, not as a legal standalone residence, and I couldn't confirm any county standard specifically for tiny homes on foundations, so ask Planning & Zoning directly about that. source
Building permits & codes
RestrictedMarion County requires a permit before you start construction on houses, garages, pole barns and similar structures, through the Planning, Zoning & Environmental Health Department. I couldn't confirm which specific building code edition the county has adopted, so ask that department for the current standard. source
Septic & composting toilets
RestrictedSeptic and other onsite wastewater systems need a county permit through Planning, Zoning & Environmental Health, on top of state design and construction standards from KDHE (K.A.R. 28-5-6) that require wastewater go to an approved system such as a septic tank, lagoon, or other approved alternative. Composting toilets aren't specifically addressed in what I found, so confirm with the county whether one meets that 'approved system' standard. source
Greywater reuse
Unclear - verifyI found no Marion County ordinance dealing with greywater reuse specifically. It likely falls under the same state onsite-wastewater rule requiring an approved disposal system, but that's not confirmed for greywater specifically, so ask the county's Environmental Health division directly.
Rainwater harvesting
Generally allowedNo Marion County rule restricts rainwater collection, and Kansas's domestic-use exemption under the state Water Appropriation Act is the baseline that applies here with no county deviation found.
Private wells & water rights
RestrictedMarion County's Environmental Health office handles consultation and permitting for domestic wells and offers water quality screening, while actual well construction standards and contractor licensing come from KDHE under state law (K.S.A. 82a-1205 and related regulations). I couldn't confirm whether Marion County also requires its own separate well construction permit beyond water testing, so check with the county and KDHE's county well-permit list. source
Living disconnected from utilities
Unclear - verifyMarion County has no separate off-grid occupancy ordinance that I found; instead, living off the utility grid is effectively controlled through the same structure, wastewater, and well permits required for any dwelling on unincorporated land. There's no confirmed mandate to hook up to public utilities where none exist, but you still need the septic and well permits in hand to legally occupy the place, so this is worth confirming directly with the Planning, Zoning & Environmental Health Department. source
