Why Build an ADU
More Possibility From the Property You Already Own
San Diego’s high housing demand makes a well-planned ADU one of the most flexible investments a homeowner can make.
Multigenerational Living
Keep parents, adult children, or caregivers close while giving everyone a comfortable, private home.
Property Value
Add useful square footage and broaden your property’s appeal in San Diego’s high-demand housing market.
Flexible Space
Build a guest suite, home office, creative studio, or adaptable space that changes with your family.
One-Stop Design-Build
One Team Instead of Three Separate Companies
Most homeowners have to coordinate an architect, a permit expediter, and a separate contractor. Arrow brings all three under one roof, so decisions stay aligned, handoffs disappear, and you always know who is accountable.
Step 01
Design
We turn your goals and lot conditions into a thoughtful ADU plan, coordinating architecture and engineering.
Step 02
Permitting
Our team prepares the submittal, manages comments, and coordinates current city or county requirements.
Step 03
Construction
The same team carries your approved plans through scheduling, building, inspections, and completion.
