Castro Valley is an unincorporated community in Alameda County, tucked into canyons between Hayward and the hills. Many houses date from the 1940s to the 1960s, and lots range from flat streets near the boulevard to steep canyon parcels.
We remodel Castro Valley kitchens and bathrooms and take on additions and ADUs. Because the area has no city government, permits go through Alameda County, and we handle that submission for you.
Housing context
Castro Valley homes often combine original small kitchens with later add-ons of mixed quality. On canyon lots, drainage and retaining walls are worth checking before any addition.

What matters in Castro Valley
County permits
Building permits come from Alameda County Community Development rather than a city. We prepare drawings to the County's requirements.
Earlier additions
Past additions may not match the original framing. We inspect them before tying new work in.
Canyon lots
Slopes and retaining walls affect access and foundations. We assess them during the first visit.
Room for an ADU
Deeper lots often fit an ADU or garage conversion, subject to County rules on size and setbacks.
Castro Valley / Design & permits
Design, drawings and permits for Castro Valley
In Castro Valley, building permits are issued by the Alameda County Public Works Agency (Building Inspection). We prepare the drawings, file the application and answer plan-check comments for you, and when a Castro Valley project needs architectural plans, our in-house licensed architect draws them.
