How a barndominium gets built in the Kansas City metro

Before anyone draws a floor plan, we confirm the parcel can legally and physically take a house and a shop. On the outskirts of Kansas City, in rural Johnson, Miami, Cass, Clay, Platte, Leavenworth and Jackson counties, that answer changes from parcel to parcel.

• You decide: which parcel, where on it the building goes, and whether you'll buy before or after the feasibility answers come back.
• We handle: zoning and access questions with the right office, the driveway or entrance route, the utility path, water source, and septic or sewer feasibility. We walk the site after heavy rain whenever we can, and we check the parcel on the FEMA Flood Map Service Center.

Zoning can follow parcel size. In Cass County, Missouri, parcels over 20 acres are zoned Agricultural and smaller parcels are treated as residential, according to the county zoning department's procedures. So splitting a tract can change what you're allowed to build on it.

Get utility and zoning answers in writing before you close on the land.

A barndominium plan has two parts that have to agree: the structural building (post-frame or steel) and the house inside it. We put them on one coordinated drawing set.

• You decide: living-to-shop split, room layout, door sizes, ceiling heights, and the finish level you're aiming for.
• We handle: an engineered structural design for both residential and shop use, foundation details matched to that structure, and the room, systems and energy details the permit office needs.

Simple shed plans don't cover a home. Cass County's published post-frame standards apply to agricultural and residential accessory buildings up to 3,000 square feet and 40 feet wide. Anything bigger has to be designed by a registered Missouri structural engineer. A home needs a residential design, not a farm-building detail sheet.

This is also when we price the job. Our Kansas City barndominium cost guide explains how a kit, an assembled shell and a finished home differ, and why we price by phase.

The slab is foundation, finished floor and often the heating system, all in one pour. Once it's in, plumbing, floor drains and conduit can't move without cutting concrete.

• You decide: final floor plan, bathroom and kitchen locations, floor drains, in-floor heat, and any heavy equipment or vehicle zones in the shop.
• We handle: frost-depth footings, base and vapor retarder, every under-slab sleeve and rough-in, radiant tubing if you choose it, and the inspection before the pour.

Frost depth matters here. Johnson County building officials' residential foundation guideline sets frost footings at no less than 36 inches below grade. We confirm the requirement with whichever jurisdiction reviews your parcel. More detail is on our barndominium slab and concrete floor page.

Lock the floor plan before the slab. That one rule prevents most change-order pain.

The shell takes the project to "dried-in": frame, roof, wall panels, exterior doors and windows. It's the fastest-looking part of the build, and it's where kit-only buyers most often find gaps in scope.

• You decide: exterior colors, door and window selections, porch or lean-to additions, and insulation approach.
• We handle: erection, flashing and openings, and making sure the shell scope lines up with the slab and the interior plan. We check shell lead times before anyone talks about a move-in date.

If you're comparing a kit or shell-only package, read what's actually in a shell or kit proposal first.

Permits start before land work ends. Inspections then cluster around footings and slab, framing, rough electrical, plumbing and mechanical, insulation, final, and occupancy. Who does them depends on where the parcel sits.

Wastewater, the road entrance and floodplain work often go through separate offices from the building permit. We track every approval on one sheet so nothing gets covered up before it's inspected. For the full county-by-county walkthrough, see getting a barndominium permitted in the Kansas City metro.

One person on our side answers every review comment, and nothing gets closed in before its inspection passes.

Interior finish is where two identical shells turn into very different budgets. Drywall, cabinets, fixtures, flooring and the final polish or coating on an exposed slab all happen here.

• You decide: selections, ideally early enough that allowances become real products with real prices.
• We handle: trade sequencing, protecting the finished slab, final inspections, corrections, exterior cleanup, and the occupancy and completion paperwork your lender needs.

Lenders have their own completion requirements, separate from the building department's. Our barndominium financing guide covers construction-to-permanent loans and draw schedules.

• Parcel address or search area, and whether you own it yet
• Rough living and shop square footage
• Must-have rooms, doors and shop uses
• Finish level and budget range
• Any survey, utility letters or county answers you already have

That's enough for us to tell you which step you're on and what has to happen next.
