Building permits, zoning and land rules in Pottawatomie County, Kansas

Yes. Pottawatomie County requires a building permit for site-built dwellings and accessory structures, manufactured homes, moved-in homes, and additions⁶. Small storage sheds of 120 square feet or less, fences, playhouses, and play equipment are exempt⁶. Agricultural structures still need a permit for floodplain and setback review, although the permit carries no fee on 40 acres or more⁶. A county permit does not necessarily include full building-code review: except for commercial ADA requirements, the county has adopted building codes only within the Blue Township Sewer District, and buyers outside that district are responsible for checking construction quality and code compliance⁹.

The Pottawatomie County Planning & Zoning Office issues building and sign permits and administers zoning, subdivision review, addressing, and floodplain management³. The office is at 207 N. 1st, Westmoreland, KS 66549, and its phone number is 785-457-3551³. A residential dwelling permit costs $200, while residential additions and accessory structures cost $50¹⁰. Ask the office to identify the parcel's zoning district, jurisdiction, floodplain status, and application before preparing plans^2,3. We could not confirm the complete inspection sequence or a general certificate-of-occupancy rule for ordinary construction; ask Planning & Zoning what inspections and closeout documents apply³.

Yes. The county Unified Development Regulations apply to unincorporated Pottawatomie County, except designated extraterritorial-jurisdiction areas for Wamego and St. Marys, while incorporated municipalities may administer their own rules². Rural tracts generally need at least 3 acres with rural water or 5 acres with an individual well, with final size tied to water and sanitary-disposal needs and subject to stated exceptions⁷. Residential height limits depend on the development type: rural and urban residential tables use 2 stories, while planned-unit developments have a 37-foot limit⁷. In the residential tables, buildings sit 40 feet from a county road and 25 feet from an internal street, with a written reduction possible where floodplain or topography makes 40 feet impractical; side and rear yards are 14 feet in Article 5 districts and 8 feet in Article 6 districts, and individual plats can differ⁷. We could not confirm a countywide minimum dwelling size or numeric setbacks for non-residential districts; ask Planning & Zoning to check the zoning map, plat, and recorded covenants³.

Pottawatomie County Environmental Health administers private wastewater and water-disposal systems from 612 E. Campbell St., Westmoreland, KS 66549, at 785-457-3397⁵. A site plan must be reviewed before a health permit is issued, and work cannot begin before issuance⁴. The fee is $150 for new construction and $25 for reconstruction; starting first can add a $100 late-inspection fee⁴. The Sanitarian must approve the installed septic system before a residence is occupied¹¹. A private system within 400 feet of an existing public sewer is allowed only when connection is infeasible and the county certifies compliance¹². Environmental Health also issues the annual non-public water supply permit, which costs $75 per year⁵. Septic permits are a county Environmental Health matter, separate from the Planning & Zoning building permit and from any city's rules⁵. Only about 1.2% of county soils are rated without severe limits for a conventional drain field, so make wastewater feasibility an early purchase contingency¹³.

In unincorporated Pottawatomie County, a building, structure, or vehicle cannot be used as a temporary residence unless the underlying zoning district permits that use or the site is part of a designated RV or manufactured-home park⁷. Temporary camping that is not use as a residence remains unconfirmed; ask Planning & Zoning before placing an RV³. A tiny home can qualify as an accessory dwelling unit when permanently founded in a district allowing single-family housing and when the county's ownership, size, setback, sewer, parking, and plan conditions are met⁷. Manufactured homes follow separate placement rules, including options for operating farms of 40 acres or more, qualifying agricultural tracts, mobile-home parks, and residential-designed homes that meet the stated standards⁸.

1. Ask Planning & Zoning to identify the parcel's jurisdiction and zoning district^2,3.
2. Confirm tract size, setbacks, floodplain status, and plat or subdivision conditions^3,7,14.
3. Resolve water and wastewater service with Environmental Health; areas outside county sewer districts generally use private wastewater systems^5,15.
4. Apply to the county for a new entrance before adding a driveway to a county road, or obtain a state permit for a state-highway connection^16,17.
5. Submit the building-permit application to Planning & Zoning and the wastewater site plan and health-permit application to Environmental Health^4,6.
6. Arrange wastewater inspection before covering or operation, and obtain Sanitarian approval before occupying the residence^4,11.
7. Ask Planning & Zoning which building inspections and closeout documents apply³.

Start with jurisdiction: county zoning excludes designated extraterritorial areas for Wamego and St. Marys, while incorporated municipalities may apply their own rules². Verify zoning, plat restrictions, floodplain status, access, and whether a proposed split needs rezoning and platting^3,6. Test wastewater feasibility before closing because only about 1.2% of county soils are rated without severe limits for a conventional drain field¹³. Confirm whether the parcel has county sewer, rural-water service, or needs private systems¹⁵. A new county-road entrance requires an application, and a state-highway driveway requires a separate state permit^16,17. Pottawatomie County's effective property-tax rate is about 1.1%, with a median annual bill of about $2,475¹³.
