How it works
A clear design-build path
Our small crew handles design, permitting, and construction together — you get to know us once, not a new face at every phase.
- 01
A Conversation, Not a Sales Pitch
One of our own family walks your property with you, listens to what the space is actually for, and talks through what your lot and San Jose zoning realistically allow.
- 02
A Plan You Understand
We design around how you'll live in the space and hand you a fixed-scope proposal in plain language — you'll know the same person who drew it up.
- 03
Permitting, Handled Personally
We prepare and submit your permit package and stay on the phone with the City of San Jose ourselves until it's approved — no rotating case managers.
- 04
Built By People You've Met
The same small crew that met you on day one finishes your ADU, walks you through final inspection, and hands you the keys.
A family-run builder for Almaden Valley and across Santa Clara County
We're a small crew, not a call center
An accessory dwelling unit usually starts with a family conversation — an aging parent, a grown child, or the need for rental income — and we like to keep it that way through the whole build. You'll know our names, we'll know your property, and the same small team stays on your project from the first site visit to the day you get your keys.
- A small, family-run crew — you deal with the same people from first visit to final walkthrough
- Fixed-scope proposals, explained face to face, so you know the price before we start
- We personally manage your San Jose permit file, start to finish
- Licensed, insured, and backed by a written workmanship warranty

Questions
Frequently asked
You'll be working with us directly. We're a small, family-run ADU builder — the person who visits your property for feasibility is the same person you'll be texting throughout construction, not a rotating sales rep.
It depends on the type and size. Garage conversions typically run $120k–$220k, junior ADUs $90k–$160k, and new detached ADUs $250k–$450k. We walk through the numbers with you in person before you commit to anything.
Because we treat each build that way. Many of our projects are for aging parents or grown children moving closer to home, so we spend real time understanding how a family will actually live around the new space before we design it.
Yes, personally. We prepare the full permit package and stay on the phone with the City of San Jose ourselves through submittal to approval — you're never chasing us for updates.
California statewide standards generally allow detached ADUs up to 1,200 sq ft, and junior ADUs up to 500 sq ft. We confirm your exact lot's numbers together, in person, during feasibility.
Yes. As a small, family-run outfit we don't hand your project off between departments — the same people who scope your build are the ones who finish it and hand you the keys.
