The local rulesLeavenworth County, KS
Zoning & raw-land occupancy
RestrictedLeavenworth County Planning & Zoning administers countywide Zoning and Subdivision Regulations for unincorporated areas only; the six incorporated cities (Leavenworth, Lansing, Basehor, Tonganoxie, Easton, Linwood) have their own zoning not covered here. source
Dwellings, tiny homes & RVs
Unclear - verifyThe county has zoning regulations and an Accessory Dwelling Unit Policy on file, but specific tiny-home or RV occupancy standards were not found in official sources; confirm directly with Planning & Zoning. source
Building permits & codes
RestrictedLeavenworth County Planning & Zoning requires a building permit for any structure in unincorporated areas, except structures under 200 square feet; permits are valid one year from issuance. source
Septic & composting toilets
RestrictedThe Leavenworth County Sanitary Code sets its own standards on top of KDHE's baseline, regulating composting-style privies, restricting lagoon systems to large tracts as a last resort, and requiring resale inspections of septic systems. source
Greywater reuse
Unclear - verifyNo county-specific greywater rule was found separate from the general on-site wastewater definition in the Sanitary Code; this appears to inherit the state KDHE baseline, so confirm with Planning & Zoning. source
Rainwater harvesting
Generally allowedNo county rainwater ordinance was found; this inherits the state baseline under the Kansas Water Appropriation Act's domestic-use exemption, administered by the Kansas Department of Agriculture, not the county.
Private wells & water rights
Generally allowedWell construction is governed by state KDHE standards; the county's added requirement is that abandoned wells found during resale septic inspections must be filled per KDHE regulations before occupancy. source
Living disconnected from utilities
Varies locallySeptic instead of municipal sewer is common and accepted in unincorporated Leavenworth County, but no official county provision on requiring or forbidding full electric/water utility disconnection was found; treat as unclear and confirm with the county. source
