22'x22' Two Car ADU Garage Loft Architectural Plans

22' x 22' Two Car ADU Garage Loft Architectural Plans

The 22' x 22' Two Car ADU Garage Loft is a complete architectural plan set for a detached two-car garage with a full livable loft apartment above — 960 square feet of combined space that adds real value to any property. Compact enough to fit on lots where a larger garage footprint isn't possible, but complete enough to function as a genuine accessory dwelling unit with one bedroom and one bathroom above a full two-car garage below.

The loft apartment is suited for a rental unit, a guest suite, a home office, or housing for a family member. The concrete slab foundation is the standard for garage construction and provides a durable, permanent base. The 95 PSF roof load handles moderate to heavy snowfall across most US climates.

Who This Plan Is For

Property owners who want to add an Accessory Dwelling Unit on a tighter lot where a larger garage footprint isn't feasible. The 22x22 square footprint is one of the most lot-friendly configurations in our ADU Garage series while still delivering a true two-car bay below and a complete one-bedroom apartment above. The loft generates rental income, houses family members, or serves as a dedicated workspace. ADU regulations vary by municipality — check your local zoning ordinance for setback and square footage requirements before purchasing.
