Garage Addition

Park Inside Again, With Room for More

Both cars under a roof, doors opening without anyone turning sideways to get out. A hood that does not turn yellow every April.

The mower and the bikes off the floor and onto a wall. A workbench that stays set up because nothing has to move for a car. Room to open a tailgate.

Before & After

Two-Story Garage Addition from Start to Finish

What You Can Build

Attached garage. Connects to the house, usually through a mudroom or the kitchen. The shared wall needs fire-rated drywall and a self-closing door into the house, which is code and not optional.

Detached garage. Sits on its own pad away from the house. More freedom on placement and size, and power or heat means trenching from the house to reach it.

Extension to the garage you have. Adds depth for a workbench or width for a third bay, without starting over. Two bays run about 24 by 24 feet, three closer to 32 by 24.

Garage with a room above. A second-story addition over the bays, finished as an office, a gym, or a shop with real power in it. If it is for family to live in, that is a mother in law suite, and if it needs its own kitchen and entrance, an ADU.

Carport to garage. Enclosing what is already covered.

What Goes In It

Doors and openers. Insulated doors and quiet openers, with headroom for a lift if that is where this is going.

Power that keeps up. A subpanel and outlets where the workbench actually is. A 240-volt circuit if you are charging a car or running a welder.

Insulation and heat. Worth doing if you plan to use the space in January. Also keeps the room above it comfortable.

Floor. A sealed or coated slab that cleans up after a spill.

Storage. Overhead racks and wall systems. A loft if the roof pitch allows one.

What Drives the Cost of an In Law Suite

Size sets the baseline, and a third bay costs more than a deeper two. A sloped lot is the most expensive place to put one, since it means grading and a taller foundation first.

Detached costs more than attached, because it needs its own foundation and utility runs. A finished room above is the bigger jump, since that is a full second floor.

The estimate breaks out every line before we start.
