About this plan

A 22 by 24 foot garage with a one-bedroom apartment above, 528 square feet upstairs, drawn on a concrete slab with a 6 in 12 roof pitch. These adu garage plans come as a complete PDF set.

Built to stay under a height limit

The 6 in 12 pitch is the defining choice. It is shallower than the other garage apartments in the range, which keeps the ridge at 23 feet 6 inches while still giving eight foot ceilings upstairs. If your lot has a height restriction that rules out a steeper accessory building, this is the plan that fits under it.

The utility closet

There is a utility closet on the ground floor. Putting the water heater, the panel and the mechanical plant downstairs means none of the 528 square feet upstairs is given over to equipment, and servicing it never involves going through the apartment. Small detail, disproportionate effect on how the unit lives.

Upstairs and down

The apartment holds a bedroom, a bathroom, and kitchen and living space. Below, two seven by eight foot doors take two vehicles.

Before you build

Accessory dwelling rules vary more than almost any other part of the residential code. Some jurisdictions permit them outright, some cap the floor area, some require a separate utility connection or an extra parking space. Check what your county allows before you order materials. The rules have been loosening across much of the country, so if you were told no a few years ago it is worth asking again.

Code requirements are set locally. The International Code Council publishes the model codes most United States jurisdictions adopt.
