Kansas City Region
Platte County permits are for unincorporated projects
Platte County Planning and Zoning handles permits for county-jurisdiction projects, so city addresses should check their own city hall first.
Before a Platte County project reaches a permit form, it needs a city-limits check. County Planning and Zoning handles projects under county jurisdiction, including plan review and permits for new construction, accessory structures, additions, decks, swimming pools, solar panels, mechanical changes, and demolitions.
A project inside Parkville, Platte City, Riverside, Kansas City, or another municipality may need city review instead. Platte County’s activity search tool reinforces that split by showing county-jurisdiction or county-funded activity, not city building permits.
Before pricing a remodel, pool, shop building, or demolition, confirm whether the parcel is inside a city. The mailing address may say Platte County, but the permit counter may still be city hall, especially in the faster-growing Kansas City edge of the county.
