Drywall, flooring, cabinetry, electrical, plumbing, and HVAC go in. We coordinate all trades to ensure quality and code compliance throughout.

You'll always know what's happening next—and when.
Our Services
We handle the full scope of ADU construction, from initial design consultation through final inspection and certificate of occupancy in Redwood City.
Detached ADUs & Backyard Units
Detached units give families maximum flexibility and privacy. Whether you're adding a backyard cottage in Farm Hill or a second structure on a larger lot in Redwood Shores, we handle site prep, foundation, and all connections to your main home.
Detached units work best on properties with space and clear setbacks from property lines. We navigate Redwood City's site requirements and design units that fit your land.

Attached ADUs & Garage Conversions
Converting a garage or adding an attached unit maximizes your home's footprint. Many Redwood City properties have existing garages or side yards suited for this approach. We handle structural connections, electrical integration, and parking solutions.
Attached ADUs can reduce costs compared to detached units and are ideal for aging parents or adult children living nearby. We'll explore all zoning allowances for your property.

Why It Matters
An ADU is one of the smartest moves for Redwood City homeowners. Here's why families trust us to build theirs.
Rental Income & Long-Term Value
An ADU transforms your home equity into cash flow. In Redwood City, rental rates for one-bedroom ADUs are strong—many homeowners recoup their investment in years, not decades.
Beyond monthly income, a built ADU increases your home's appraisal value. Buyers see it as a bonus asset, especially in neighborhoods like Downtown and Redwood Shores where housing demand stays high.
Homeowners renting ADUs generate an average additional income of 30% of their mortgage costs, creating meaningful financial flexibility.
Multi-Generational Living & Flexibility
More Redwood City families are choosing to live together—aging parents, adult children, or extended family. An ADU keeps everyone close while preserving independence and privacy.
Whether your needs change over time or you want an in-law suite now, an ADU adapts. It can be a rental, a workspace, or a sanctuary for the next chapter of family life.
Your home, your family, your way—an ADU makes it all possible.
