Project overview
About this project
The converted building now has gray stucco walls, white-trimmed windows, two wood craftsman entry doors and a white sliding door on the gable end. A gray paver patio wraps the entries and the sliding door.
Inside, the living room and kitchen share one open space with wood-look plank flooring and recessed lights. The kitchen has white shaker cabinets with under-cabinet lights, gray subway tile, a white quartz-look island with seating, stainless appliances and a matte black faucet.
Two bedrooms sit off the hallway, each with clerestory or standard windows, and one with mirrored closet doors. The bathroom has large onyx-look wall tile, a black-framed sliding shower door, a linear drain and a wood-look vanity, and a washer and dryer fit in a built-in alcove with a shelf.

How we work
How a project like this comes together
The same five steps run every Quartz job, from the first visit to the final walkthrough. One team designs, permits and builds it.
Site visit and feasibility
We look at the lot or garage, utilities, access and setbacks, and talk through how you plan to use the unit.
Design and plans
Floor plan, kitchen and bath layout, and finishes are drawn up and prepared for the city.
Permits
We prepare and submit the permit package and coordinate plan check with the city or county.
Construction
Foundation or slab work, framing, utilities, insulation, drywall, then kitchen, bath and finishes.
Final inspection and walkthrough
The unit passes final inspection and we walk it with you before handing over the keys.
Questions & answers
ADUs & garage conversions: common questions
Planning something similar? These are the questions homeowners ask us most. Anything else, just call.
(650) 749-7436Do you handle ADU permits?
Yes. As your general contractor we prepare the permit package, submit it to the city or county and coordinate inspections through final sign-off.
Can a detached garage be converted into an ADU?
Often, yes. It depends on the structure, the slab, setbacks and utilities. We check those on a site visit before any design work.
What does an ADU need inside?
A legal ADU needs its own kitchen, a full bathroom, a sleeping area and a separate entrance. Heating and cooling, laundry and storage are planned into the layout.
Can I rent out an ADU?
In California, ADUs are commonly used as rentals or for family. Local rules on rental terms vary by city, so check your city's ADU rules for your lot.
Do you work in my city?
Our office is in San Jose and we build across Santa Clara, San Mateo, Alameda and Contra Costa counties. Call us to confirm your address.
Client reviews
What our clients say on Google
We had an amazing experience with Quartz Construction for our garage conversion ADU. The entire process was smooth and stress-free—they made everything incredibly easy for us from start to finish. Our project manager, Ohad, was fantastic to work with. He was always available, professional, and made sure everything ran smoothly. On top of that, they also completed a full backyard renovation, and the results exceeded our expectations. The quality of work and attention to detail were outstanding. Highly recommend them to anyone looking for a reliable and professional construction company!
We hired Ohad and his crew for a home addition, and they did a fantastic job. The new area feels like it’s always been part of the house. Great craftsmanship and smooth process.
Working with Ohad on our full home remodel was an incredible experience. He helped us through every decision and made sure everything turned out exactly how we envisioned. The team was easy to communicate with and super detail-focused. We still can’t believe how beautiful our home looks!
