The track record
How our projects come in
A pure ADU builder with one accountable team and a homeowner-first payment structure. Here's what that produces across the work above.
$1,000
down to start — California's legal maximum deposit, never more
Milestone draws
every payment tied to a passed inspection, so you never pay ahead of completed work
$95k–$500k
all-in project range across types, from a JADU to a full detached build
One team
design, permits, and construction under one roof — no markup chain
