Garage In-Law Suite Conversions in Kansas City

A two-car attached garage is 400–500 square feet of ground-floor space with no stairs, a slab already poured and the house's walls on one or two sides. For a parent who can't do stairs, it is often the best suite on the property — if the slab, the floor level and the parking question are handled honestly.

When a garage conversion makes sense

When ground-floor living matters more than a garage, and the lot has somewhere else for the cars. Metro subdivisions built from the 1970s on nearly all have attached two-car garages at or near the main floor level, which makes a step-free suite straightforward. The trade-offs: you lose the garage (some HOAs and cities care — we check), and a garage slab was poured for cars, not for living, so floor insulation, a vapor barrier and a floor system go in before anything else.

What we check at the design visit

  • Floor level. Most garage slabs sit a step below the house floor and slope toward the door. We build a level, insulated floor over it and tell you how the new floor meets the old threshold.
  • The door wall. The garage door opening becomes a framed, insulated wall with windows and the suite's entrance — the single biggest change to the street face, and the one your HOA will ask about first.
  • Plumbing route. A bath needs a drain under the slab; a garage next to a kitchen or laundry wall usually has one close. We check the invert and the route before the layout is set.
  • Fire separation. If any garage remains (a one-bay split), the wall and door between it and the suite stay fire-rated.
  • Parking. Your city's off-street parking rule and your HOA's covenants decide whether the driveway counts. We find out before you commit.

What we build

Insulated floor, walls and ceiling to the current energy code; the door-wall with windows and a private entrance; bedroom, full bath, living area; kitchenette where the jurisdiction allows; a dedicated mini-split or a tie-in to the house system; and a finish that makes it a room, not a converted garage.

What it costs

Nationally a garage conversion runs $20,000–$60,000 (Angi, September 21, 2026). A full bath, a kitchenette, a new HVAC zone and a replacement garage or carport elsewhere on the lot each add a line. Fixed written price after the design visit. The cost guide →
