A Place of Your Own
Use a backyard ADU to plan independent day-to-day living on a property with a primary residence. Start with its relationship to the main house, the garden and the route to the entrance.
Main Floor + Loft
Style BL pairs a one-bedroom main floor with a separate loft above. The main floor contains the kitchen, living area and bathroom; Style B offers the one-bedroom arrangement on a single level.

A Garden-Facing Finish
Compare exterior wall and roof finishes with the existing home. Interior finishes can be selected around daily use, while the porch provides a transition to the garden.
Confirm the site access, services and permitted use before developing an ADU proposal.
