ADUs & garage conversions

A small house in the backyard

Budgets from
$140,000
Time on site
4 to 6 months

An ADU is a whole house in four hundred square feet, so every inch is drawn: where the kitchen goes, where the light comes in, where the stairs to the loft don’t take up the room.

We handle the parts that stall most backyard cottages: the zoning letter, the utility runs and the inspections.

Questions

Is my lot big enough?

Most lots in the valley are. We check the setbacks and the town's rules on the first visit, free.

Is a garage conversion cheaper?

Usually by a third, if the slab and walls are sound. We'll tell you on the visit whether they are.
