Frequently asked questions
What is the difference between an accessory building and an ADU?
An ADU is a separate dwelling with its own kitchen and bathroom. An accessory building is a non-dwelling structure like a studio or workshop.
Can I add a bathroom?
Often yes, though some zones restrict it. We check before drafting.
Can I sleep in it?
If it is used as a bedroom it must meet code for sleeping rooms, and zoning may treat it as a dwelling.
Planning an accessory building?
