ADU for Walnut homes
Walnut is a residential city of rolling hills and established neighborhoods, and many homeowners here already own the main ingredient for an ADU: a generous yard. Families use backyard units for parents, for adult children returning home, and for rental income.
We look at the lot first. Setbacks, slope, existing structures and where the utilities enter the property decide what is possible. You get the findings and a written scope before any design fee or contract.
What matters in Walnut
Sloped lots
On a hillside lot we use reinforced footings and plan site drainage so the unit stays stable.
Matching the main house
Many Walnut owners want a unit that matches their house. We design rooflines, siding and windows to match.
City permits
We prepare and submit the plans to the City of Walnut and respond to review comments.
