View two story ADU floor plans and pricing. Browse accessory dwelling unit designs for two story guest houses with one to four bedrooms, the max that will fit in the 1200 sqft size limit for ADUs in California.
We can also add a second story to any of our standard plans and adapt so that it works with your property constraints and design goals. You may want to add an ADU over a new detached garage. You can also stack two ADUs if you are in a city that permits two stacked ADUs on multifamily lots.
