So your family can move in sooner, or you can rent it out faster for higher profits.
There's no end to what you can use an accessory dwelling unit for. Here are a few of the ways our clients use their Green Galaxy ADU.

Whether it's extra space for family, a rental to offset your mortgage, or a detached office or hobby room, an ADU is a smart, flexible investment that boosts both your property value and your lifestyle.
Streamlined processes and transparent quotes keep your ADU on time, on budget, and free of surprises.
Two decades of experience focused on structural integrity, craftsmanship, and durable finishes.
We know permitting and zoning in Santa Clara County and guide you every step, so you avoid costly mistakes.
We've refined a process that delivers superior quality accessory dwelling units, faster and for less.
We pre-fabricate major components off-site using Structural Insulated Panels (SIPs) for a quieter, more energy-efficient unit, built faster with fewer weather delays.
No hidden delivery or installation fees. You know exactly what your ADU will cost before we begin, and we handle permitting, code compliance, and project management.
From design to delivery we walk you through every step, so your ADU is completed exactly as you envisioned.
Building an ADU is a great way to house family or earn rental income, but there's a lot at stake. Here's what we do differently.
Our in-house team and off-site factory use CAD/CAM production on a coordinated schedule, and our supervisor has never failed an inspection in 45 years.
Structural Insulated Panels are stronger and more stable than green lumber, with a full 20-year warranty that keeps every surface straight and level.
SIP walls come insulated, so your ADU is quieter, more private room to room, and cheaper to heat and cool for its whole life.
A stable supply of materials, a reliable in-house team, and factory work unaffected by weather mean your ADU is done 25% faster.
Low-impact methods minimize waste and maximize recycling, with added efficiency, pest resistance and minimal VOCs.
We optimize your design for your property, arrange all approvals, and keep you updated with direct access to the owner.
As triple-licensed real estate professionals, we help you maximize your return. Many clients find their ADU adds double its construction cost in value.
No low-ball online prices followed by thousands in extras, and no cutting corners on the foundation and frame you can't see.
