◆ Our Process

Planning through
final delivery.

Every ADU project moves through four structured phases — no guesswork, no hand-offs.

Step 01

Planning & Feasibility

We evaluate property constraints, project goals, and ADU options before scope development.

Step 02

Design & Engineering Coordination

Design teams and structural engineering are coordinated for compliant, buildable plans.

Step 03

Permitting & Pre-Construction

Permits, city coordination, and scheduling are organized before field work begins.

Step 04

Construction & Final Delivery

We execute construction through completion, inspections, and final walkthrough turnover.
