Project overview

About this project

This ADU sits in the backyard as its own building, with gray stucco walls, white trim, a gable roof with vents and a white entry door with a half-round window. Rooftop solar panels sit on the gray shingle roof.

Inside, the front door opens into a living and dining room with recessed lights and wood-look plank flooring. The L-shaped kitchen has white shaker cabinets to the ceiling, white quartz-look counters, a gray-and-white mosaic backsplash, a white range and a stainless refrigerator and dishwasher.

One bathroom has a single white vanity and a glass shower with three hexagon-tile niches set into a hex mosaic band. The second has a white double vanity with black mirrors, matte black fixtures and a glass shower with a linear glass mosaic band and matching niches.

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.

  1. 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.

  2. Design and plans

    Floor plan, kitchen and bath layout, and finishes are drawn up and prepared for the city.

  3. Permits

    We prepare and submit the permit package and coordinate plan check with the city or county.

  4. Construction

    Foundation or slab work, framing, utilities, insulation, drywall, then kitchen, bath and finishes.

  5. 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

(650) 749-7436
Do 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.

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.

Ted M. Google review

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!
