Brentwood

ADU contractor in Brentwood

Two ADU shapes, two different builds. A detached unit is a freestanding structure with its own foundation, frame, roof and skin, put up in the open part of the lot. An attached unit borrows a wall from the house and has to be tied into it cleanly. Whichever it is, the drawing set is coordinated first and permit support runs with it. Ground-up construction follows, and the water, waste and electrical tie-ins are pulled from the existing service. Interior finish work then fits out the bath, the kitchenette, the flooring and the trim. The last item on a Brentwood job is the walkthrough, and nothing is signed off before the punch list is empty.

What does the first step look like? An Onsite Visit and Free Estimate booked at the Brentwood address. The visit is where the unit's placement, size and finish level are discussed, and it produces a written detailed scope of work plus a remodeling consultation. Both are free. From there, permit filing and plan submittal are taken on by MyCali Builders. Financing is available if the build is easier to fund that way. Work is carried out licensed and insured under CSLB #1072368 by a company in business since 2020, and finished ADUs carry a warranty of 5 years.

Brentwood area

Mandeville Canyon is one of the neighborhood names inside Brentwood. Putting a second dwelling on a lot here runs straight into the hillside access the client raises in the note on Brentwood remodels, since a ground-up build has to bring concrete, framing and utility lines to the back of a property before finish work starts.

Neighborhoods served: Brentwood Park, Mandeville Canyon, South Brentwood.

Near: San Vicente Boulevard, the Getty Center, Bundy Drive.

What is included

  • Detached and attached ADU builds

I recently hired My Cali Builders for a backyard remodel and couldn't be happier. Danny and his team were professional, punctual, and easy to communicate with. They really paid attention to the details and brought my vision to life. The quality of the work exceeded my expectations from start to finish. Everything was done cleanly and on schedule, which I really appreciated. Danny made the whole process smooth and stress-free. The backyard now looks amazing and feels like a completely new space. I would definitely recommend them to anyone looking for reliable contractors.

I began my Yelp search for a company to perform structural repairs and ultimately chose 5 companies, scheduling each of them for a representative to visit and discuss my needs. I chose My Cali Builders based upon Danny's (owner) review of the work and how he defined the scope of the work. The other representatives vacillated on the scope of the work and attached various caveats. My Cali Builders also gave me the best bid. So I hired them and boy, am I glad I did. Work was performed quickly, efficiently and the finish work was excellent. Every task I initially discussed with Danny was completed. Danny's crew including Francisco and Jaime, were top notch and pleasant. Each day, refuse and trash were removed. Every day, Danny either visited or texted to advise on progress and to insure the work was progressing as discussed and to ask if I was satisfied and happy. I can't convey in words how much I appreciated My Cali Builders. Look no further, they are the best I've ever encountered.

Danny Raz is a man of action; the work was done promptly and even finished ahead of schedule. The workers were polite, respectful, of cleaned up well after the job.

FAQs

ADU in Brentwood - common questions

Answers to the most common questions about this service in your area.

Yes. We have completed multiple ADU projects in Brentwood. Call (310) 220-0903 to schedule a free onsite visit, or compare public feedback on the customer reviews page.

ADU builds typically run 3 to 6 months from permit approval through final inspection. We map the milestone schedule before field work starts. We give you a written schedule during the estimate so milestone dates are clear before field work starts.

Yes. Permit work is carried by MyCali Builders as part of the ADU scope in Brentwood, alongside plan coordination. The drawings are assembled, submitted and followed through under CSLB #1072368. The owner is not the one managing the submittal. Its status is reported back through the build, and it is written into the scope of work handed over with the free estimate.
No published figure exists for an ADU in Brentwood. Square footage, attached or detached construction, how far the utility lines have to be run, and the finish specification all pull the number in different directions. The free onsite visit is where those are decided, and the detailed scope of work that comes out of it is what a price is built on. Nothing is quoted before that.

Yes. CA Contractor License #1072368. Fully insured for liability and workers compensation. The public record is on the CSLB lookup.

For a detached ADU, yes. The unit goes up on its own footprint and the main house keeps working throughout. An attached unit is a different matter, since there is a stretch where the new structure meets the existing one, and that period is planned before it arrives. Access, the crew's working area and material staging are agreed at the Brentwood walkthrough and written into the scope.
