The Riley County Planning and Development Department, on the second floor at 110 Courthouse Plaza in Manhattan (785-537-6332), issues the building permit required for any structure in unincorporated Riley County — the Flint Hills ranchland and small communities outside the cities. The county has adopted no building code, so the permit checks zoning, setbacks and the county Sanitary Code rather than how the building is built. Its map is unusually carved up: Fort Riley occupies the county’s western side as federal land outside county jurisdiction, Kansas State University’s property sits under the codes the Kansas Department of Administration adopts, and the City of Manhattan permits its own construction through Risk Reduction, a division of its fire department.
What remains for the county is the rural balance, where the zoning and platting questions on ranchland and the on-site wastewater question on unsewered parcels decide the permit. Riley County has adopted no building code and its inspector does not examine construction, so the construction standard is left to the owner and the builder; Kansas has no general statewide building code and no state code agency for private buildings, and the main statewide code is the Kansas Fire Prevention Code, which does not cover one- and two-family homes.
This guide covers unincorporated Riley County. The Fort Riley reservation is federal land outside county jurisdiction, state university property sits under the Department of Administration's adopted codes, and Manhattan, Ogden, Randolph and Leonardville permit their own construction.
Three jurisdictions the county does not hold. Riley County's authority stops at three boundaries: Fort Riley, which is federal land; state university property, coded by the Kansas Department of Administration; and the City of Manhattan, which permits its own. On a project anywhere near the county's populated western half, establishing which of the four authorities holds the parcel is genuinely the first task.
What requires a building permit in Riley County?
Riley County has adopted no building code for unincorporated territory: its layer is a building permit that checks zoning, setbacks and the Sanitary Code, with platting, floodplain and on-site wastewater handled by the same department.

- A county building permit for any structure in unincorporated territory, checking zoning, setbacks and the Sanitary Code — not construction, since the county has adopted no building code
- Zoning and platting approval from the county ahead of the building permit
- On-site wastewater approval where the land is unsewered
- New buildings, additions and any structural work on an existing building
- Alterations, repairs and renovations, and any change of occupancy
- Decks, accessory structures above the local threshold, retaining walls, storm shelters and swimming pools
Often exempt
- Interior work and repairs that add no structure; there is no county building code, so there are no code-based construction inspections
- Ordinary repairs that do not alter structure, egress or systems
- Direct like-for-like replacement of a fixture, where the local jurisdiction allows it without a permit
- Painting, papering, flooring, cabinets and similar finish work
- Small accessory structures below the local threshold — the zoning ordinance still applies
What is actually local, and what is not
Locally, what stands out is the federal and state landholdings the county does not permit, and its rural Flint Hills zoning.
Kansas has no general statewide building code: each city and county adopts and amends its own. A few state rules apply everywhere, led by the Kansas Fire Prevention Code. Kansas rules
Who handles permitting in Riley County?
The Planning and Development Department is the permitting authority for unincorporated Riley County, issuing building permits that check zoning, setbacks and the Sanitary Code, and administering zoning, platting and floodplain; the county has adopted no building code. The City of Manhattan permits inside its limits through its fire department’s Risk Reduction division, the Kansas Department of Administration adopts the codes for state-owned university property, Fort Riley is federal ground outside all of it, and the Office of the State Fire Marshal enforces the mandatory Kansas Fire Prevention Code.

Permit types
Residential permits
A house in unincorporated Riley County needs a county building permit, which checks zoning, setbacks and the Sanitary Code, with platting cleared first and on-site wastewater approval where the land is unsewered. The county inspector does not examine how the house is built. The Flint Hills terrain and shallow limestone soils make the wastewater and foundation questions more binding on a rural parcel here than in the flatter eastern counties.
Commercial permits
Commercial and agricultural work in unincorporated Riley County clears the county’s zoning, platting and building permit; the county does no construction plan review, but sealed drawings are still needed where the state board’s threshold is met and the State Fire Marshal reviews the occupancies within its jurisdiction. Construction on Fort Riley or on state university property is outside the county’s jurisdiction entirely.
Verifying the code before design
In unincorporated Riley County the Kansas and Big Blue river corridors and Tuttle Creek Lake bring floodplain review into the file, the Flint Hills terrain and shallow soils govern on-site wastewater and foundations, and both federal and state landholdings sit outside county jurisdiction. An assumption that a neighbouring city's code is the same is the most common and most expensive mistake made in Kansas permitting.

Riley County permit costs and fees
Fees follow the county's adopted schedule for unincorporated territory, with Manhattan's own schedule applying inside the city.
| Item | Fee or rule |
|---|---|
| Building permit | The county's adopted fee schedule, for unincorporated territory |
| Zoning and platting | County approval ahead of the permit |
| On-site wastewater | County approval where the land is unsewered |
| City permits | Manhattan's own schedule, inside the city limits |
| Federal and state land | Fort Riley and university property outside county permitting |
| Codes | None adopted by the county; each city’s own inside its limits |
Shallow soils bind the rural parcel. The Flint Hills sit on shallow soils over limestone, which constrains on-site wastewater systems and foundation design across much of rural Riley County. On an unsewered parcel the soil evaluation frequently decides whether and where a dwelling can go at all — a question that belongs before the purchase, not after the design.

How to apply for a Riley County building permit
There is no general state building code; confirm the editions and amendments this jurisdiction has adopted before design begins.
Zoning, platting and site development approvals precede the building permit and are entirely local.
Kansas has no state licence for general contractors or the main trades; the requirement is the city’s or county’s own. A licence based on a standard exam named in state law is valid in other Kansas cities and counties that license the trade. Roofers must also register with the Kansas Attorney General.
State law, administered by the Kansas State Board of Technical Professions, sets the threshold for a licensed architect or engineer.
Reviewed against the locally adopted codes and amendments, with the Kansas Fire Prevention Code applying to all but one- and two-family homes.
Footing to final, with the trades on their own permits, then the certificate of occupancy.

Riley County reviews unincorporated work through the planning and zoning department. What delays a file here is a parcel whose authority was not established among the four, and a rural dwelling designed before the soil evaluation.
Inspections in Riley County
Inspections follow the sequence of the codes the jurisdiction has adopted — footing, foundation, framing, rough trades, insulation and final — requested from the city's inspection division by permit number, with the trades inspected on their own permits. Work that passes final receives a certificate of occupancy for new buildings and changes of occupancy. Riley County’s inspection of the work it permits checks setbacks and zoning, not construction; inside Manhattan, inspection is the city’s.

Does the county permit work on Fort Riley?
No. The reservation is federal land outside county permitting jurisdiction.
Who codes the university's buildings?
State-owned university property sits under the codes the Kansas Department of Administration adopts, not the county's or the city's.
Does the county permit inside Manhattan?
No. Manhattan issues its own permits through Risk Reduction, a division of the Manhattan Fire Department; the county covers unincorporated territory.
What makes rural building difficult here?
Shallow Flint Hills soils over limestone constrain on-site wastewater systems and foundations, so the soil evaluation often decides whether a dwelling can go on a parcel at all.
Which code editions apply?
None in unincorporated Riley County: the county requires a building permit but has not adopted building codes, and its inspector does not examine how the building is constructed. Inside Manhattan and the other cities, the city’s adopted code applies.
Is anything mandatory statewide?
Mainly the Kansas Fire Prevention Code, enforced by the State Fire Marshal, which a local jurisdiction may make more stringent but not less. It does not cover one- and two-family homes.
