Read this before you act on anything below. This is my researched starting point for Pottawatomie County, KS, 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 rulesPottawatomie County, KS

Zoning & raw-land occupancy

RestrictedThe county has countywide zoning under its Unified Development Regulations, administered by the Planning and Zoning Office; raw-land use and lot standards fall under this county code, not the state. source

Dwellings, tiny homes & RVs

Varies locallyBuilding permits are issued by the county Planning & Zoning Office, and mobile/manufactured homes have separate personal-property listing requirements. Claims about Appendix Q tiny home rules and foundation requirements are not confirmed on an official county page. source

Building permits & codes

Varies locallyA building code applies only in the Blue Township Sewer District/Green Valley area; outside that district a countywide mandatory building code was not confirmed, though the Planning and Zoning Office still handles permits and floodplain review. source

Septic & composting toilets

RestrictedThe county sanitation code, authorized by state law (K.S.A. 19-3706), governs septic and wastewater systems, restricts new systems within 400 feet of public sewers, and grandfathers working existing systems unless deficiencies are found. source

Greywater reuse

Unclear - verifyNo official county or state page specifically addresses greywater reuse; it likely falls under general wastewater system provisions, but this is not confirmed, so ask Environmental Health.

Rainwater harvesting

Generally allowedNo Pottawatomie County ordinance restricting household rainwater collection was found, so this defaults to the state's general allowance for domestic use.

Private wells & water rights

Generally allowedThe county's Environmental Health Division oversees private well and water supply systems, including inspections tied to property sales, refinancing, and habitation, while well construction itself follows KDHE's statewide standards. source

Living disconnected from utilities

Unclear - verifyNo official county page explicitly requires connecting to grid utilities for occupancy outside the Blue Township/Green Valley building code district; the clearest restriction found relates to distance from public sewer lines under the sanitation code. source
