Buying Land in Ray County, Missouri

Zoning: Ray County is the exception, not the rule

Most Missouri counties have never adopted the countywide zoning authority RSMo Chapter 64 makes available to them, but Ray County has: it runs an active Planning & Zoning department out of the county courthouse in Richmond, with an administrator, a board that meets monthly, and a real zoning-district map covering unincorporated land. The county's three residential districts are set by acreage rather than lot dimensions -- R-A for 19 acres and up, R-1 for 9.00 to 18.99 acres, and R-1A for 3.00 to 8.99 acres -- alongside agricultural and other district classes, and land uses outside what a district allows as-of-right generally require a Conditional Use Permit from the board.

That active zoning regime extends into places most Missouri counties don't touch at all: Ray County's Planning & Zoning office issues a distinct Solar Permit application, meaning a utility-scale or even a larger private solar installation here runs through an actual county permit process rather than a straight negotiation with the County Commission over road access, as it would in an unzoned county. The county has also adopted its own accessory-dwelling-unit rules -- an ADU incorporated into or within 100 feet of a principal structure is allowed by-right in the R-A, R-1, and R-1A districts (one per lot, and only if it's never rented, covering things like a mother-in-law suite or guest house), with a Conditional Use Permit path in other districts. See our dedicated zoning page for Ray County for the full district structure, the ADU rules, and the subdivision and building-permit process in more detail.

Because Ray County sits inside the Kansas City metro area and borders Clay County -- itself a zoned, more suburban county -- treat this as land where the zoning conversation is not optional. Confirm a specific parcel's district, any recorded conditional-use history, and setback requirements directly with Planning & Zoning (816-776-5398) before you buy, rather than assuming rural Missouri's usual absence of zoning applies here.

Building, septic, and subdivision: a real permit process with real fees

Ray County reports a $150 building permit fee and a $300 septic permit fee (plus an additional $100 if you plan to self-install rather than hire a certified installer), and a soil morphology test is required before the county will accept a septic application -- consistent with the statewide OWTS framework under Chapter 701 RSMo and Missouri DHSS rules, administered locally by the Ray County Health Department (820 E. Lexington St., Richmond, MO 64085; 816-776-5413). Reported penalties for starting construction without pulling a permit first run $250 to $1,000, a real enforcement risk that simply doesn't exist the same way in a Missouri county without zoning or building-permit staff.

Subdividing land in unincorporated Ray County means submitting a plat to the Planning & Zoning board before the County Commission and County Clerk can sign off and record it, per the county's adopted subdivision regulations under RSMo Chapter 64 and Section 89.440's plat-recording rules -- every owner of record has to sign the plat before a notary, and copies go to Planning & Zoning with the filing fee. If you're assembling or splitting acreage here, build that review step into your timeline rather than treating a plat as a simple recording-office errand.

The Missouri River, farmland, and a live levee-setback study

Ray County's southern and western edges run along the Missouri River, and the county's row-crop bottomland took real damage in the historic 2019 Missouri River flooding that hit farm ground across the state. In response, the U.S. Army Corps of Engineers (Omaha and Kansas City Districts) has been developing the Lower Missouri River Flood Risk and Resiliency System Plan, a programmatic environmental review covering the entire lower river corridor; one of the alternatives under study would set back and realign levees to give the river more room during floods, which could mean less farmable acreage protected behind some existing levee lines. The draft plan and its environmental impact statement went through a public comment period that was extended into April 2026, with the Corps now targeting final completion around March 2027 rather than the earlier May 2026 estimate.

This isn't a hypothetical for Ray County specifically: Tom Waters, a Ray County farmer, chairs the Missouri Levee and Drainage District Association and has been a vocal critic of how much farmland a large-scale setback approach could take out of production statewide. If you're looking at Missouri River bottomland in the county, ask both the seller and, where relevant, the local levee and drainage district directly about the property's current levee protection and whether it falls inside any area the Corps' plan is studying for setback or realignment -- this is a live process, not settled history, and its outcome could affect flood-zone status and levee assessments on river-bottom parcels for years to come.

Away from the river, Ray County's economy still runs substantially on row-crop and cattle agriculture -- corn, soybeans, and cattle production supported through MU Extension's Ray County office in Richmond -- even as the county's location inside the Kansas City metro area, roughly 30 miles from downtown, has kept its population essentially stable (about 23,400 as of the mid-2020s) rather than declining the way many purely rural Missouri counties have. Excelsior Springs, a historic spa city, straddles the Ray-Clay county line and is itself part of the Kansas City metro, which is a useful reminder that Ray County's western edge functions quite differently from its more purely agricultural eastern half.
