Floor plans

Garage conversion floor plans: common layouts

A typical 2-car garage is roughly 20 ft × 20 ft (about 400 sq ft) — enough for a studio or compact one-bedroom. These simplified concepts show how the same footprint can be arranged. They are illustrative only, not construction drawings.

Studio / open ADU

One open room plus a kitchenette and bath. Efficient plumbing (kitchen and bath share a wall) keeps cost down.

One-bedroom ADU

A separate bedroom adds privacy but needs an egress window and a wall. Best in a 2-car or larger garage.

Office + storage

Simplest and cheapest — no plumbing. Keep a storage zone if you are giving up the garage's utility.

Guest suite

A bedroom with its own bath. The bathroom drives plumbing cost; place it near existing lines if possible.

Planning considerations for any layout

  • Plumbing clustering: keep kitchen and bath on a shared wall to minimize runs.
  • Egress: any sleeping room generally needs a compliant egress window or door.
  • The garage-door wall: usually becomes an insulated wall with a window or a new entry.
  • Ceiling height: confirms whether the space meets habitable-room minimums.
  • Natural light & ventilation: plan window locations early.
  • Entry & privacy: ADUs typically need a separate, accessible entrance.

We intentionally do not offer a floor-plan editor. For real drawings, a designer or architect will produce plans suited to your garage and local code. Start by understanding your constraints with the assessment.

The assessment flags the factors that will most shape your layout.
