Santa Clara ADU Builder.
Mission College scale, predictable plan-check.
Santa Clara's building department is among the smoother Silicon Valley jurisdictions — clear standards, reasonable timelines, and a city actively encouraging ADU development. Lot patterns are mostly mid-century tract, which works well for both detached units and garage conversions.
