Simi Valley

ADU contractor in Simi Valley

Every accessory dwelling unit runs through the same four stages, and the interesting decisions are all in the first one. Plan coordination is where detached or attached is settled, where the unit is placed, how big it is, and how the structural and permit sets come together as one submittal. Ground-up construction is the visible half: excavation, footings, slab, framing, roof, envelope. Utility tie-ins bring a water supply, a waste line and an electrical feed with dwelling capacity to the new building. Interior finish work covers insulation, drywall, cabinetry, worktops, flooring, tile, doors and paint. The last item is a final walkthrough with a written punch list that gets closed rather than filed.

Get in touch on (310) 220-0903, by call or text, and an Onsite Visit + Free Estimate is scheduled. It includes a detailed scope of work and a remodeling consultation, and it is free in both halves. Treat the appointment as a measuring exercise rather than a pitch. The useful part is what gets recorded: the yard, the existing services, the access, the constraints you already know about and the ones you do not. Everything written afterwards rests on what was seen that day. No price for this work is published on this site. Permit filing is handled by the builder. Financing is available. The completed unit carries a warranty of 5 years, and the contractor is licensed and insured under licence CSLB #1072368, in business since 2020.

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 Simi Valley - common questions

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

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

It runs as a sequence of stages rather than one number. Drawings and plan coordination, then the permit submittal, then ground work and foundation, framing and roof, rough services, finishes, and the final walkthrough. Nothing overlaps that should not, and each stage closes before the next begins. The realistic programme for your property is written into the scope of work you receive after the free onsite visit.

ADU builds require permits and we handle the full submittal, plan check, and inspection sequence. Permit timelines vary by city and we factor them into the schedule from day one. You can also step back to the main Simi Valley page to compare related local services.

No number is published. On a build of this kind the size, the foundation, whether the unit stands alone, the length of the water, waste and electrical runs, and the finish level are what move it, and none of those can be judged from a phone call. The free onsite visit and the written scope of work that comes out of it are where the figure is built.

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

Call or text (310) 220-0903 and describe roughly what you have in mind. A visit is arranged, the lot is walked with you, siting and size are talked through, and the result is a detailed scope of work plus a remodeling consultation at no cost. Nothing is committed at that point, and the scope is yours whether you build with this contractor or not.
