My dad bought one of these houses, and after a year, it started to break down. We contacted the company, but they refused to take responsibility. So we hired someone to come and fix the house, and we found that the inside is a mess, poorly made, and of no quality. It looks nice on the outside, but the inside is a disaster. We would never recommend anything like this.
Price assessment: Overpriced

Cover knows it stuff! All the founders and personnel are beyond reproach. I have a long history of renovations and property ownership. They made my life so easy and I'm OCD . The process with Cover was smooth and interactive. From my first contact with them to receiving the Certificate of Occupancy for my ADU required little effort from me. If you are building a custom home or ADU, I highly recommend Cover.

As a fellow contractor in Southern California, I’ve seen a lot of builders in the ADU space — and Cover Build is easily one of the most impressive operations out there.
I run a construction business myself (West Coast Deck), so I pay close attention to companies that are doing things differently — and better. What Cover Build is doing with ADUs is truly next level. Their process is fast, innovative, and systematized in a way that most builders dream of achieving. They consistently deliver modern, high-quality units in timelines that traditional crews can’t match.
What really stands out is how seamlessly they combine design, engineering, and field execution. Their builds are sharp, well-thought-out, and built to last — and they manage all of it while maintaining excellent client communication and project flow.
If you’re a homeowner considering an ADU or even another builder looking to stay sharp in the market, Cover Build is a company to watch — and learn from. They’re leading the way in the prefab and modular space, and they’re doing it with integrity and consistency.
Massive respect from us at West Coast Deck.

We just got the keys to our 1-Bedroom Cover ADU, and we're so pleased with how everything turned out!
If you check out any Cover-related content online, or visit one in person ...it's easy to tell they've got top quality materials, fixtures, and design.
Since this ADU is for my parents, I obviously wanted the best quality! But what we didn't know we wanted was SPEED:
-Permits cleared in less than a month.
-Breaking ground to final inspection in 45 days.
-End-to-end ...initial Cover agreement to Certificate of Occupancy in 3.5 months.
It's all thanks to the shared expertise of the entire Cover team, but I'll call out some standouts anyways:
-Alexis & Jemuel's tech that has these builds down to a literal science
-Rico & Alden's creativity and resourcefulness in squeezing the most upgrades possible into our guaranteed, upfront pricing
-Leor's uncanny ability to keep the project on track and the inspectors happy!
It's a huge relief to have the project done on budget and ahead of schedule. What my family needed was a team we could trust to deliver. We found one at Cover.

The whole team is extremely knowledgeable. Trusted them 100% the moment I walked through their door. What they are doing here is truly incredible and I can’t wait to build my backyard home.

The entire team at Cover is first in class. They are hardworking, passionate and dedicated to their craft. I’ve toured their factory recently and was amazed to witness their innovation and see how their technology is applied in the real world. I cannot wait to see what else this team at Cover comes up with next. True class and only quality comes from them. They are geniuses. Much respect for them!

Our first dive into ADU's was very interesting, we spoke with 4 companies and each one delivered vastly different designs and price points. "Cover" was the best overall, the consultation process was dare I say..."delightful". Rico and Anna would take our wish lists and turn them into something that you usually see with a high level design firm. No other company offered this type of personal service- not because they didn't want to, they just did not have the capabilities. We were told that we could visit their sites and make our plans accordingly. That was not going to work for us with Covid shuttering the city down. The renderings were beautiful, modern and thought thru. We had limited space so thinking out of the box was crucial. The pandemic took a toll on our family and we had to stop the process, but I would recommend this company without hesitation if someone was shopping for a FULL SERVICE ADU company.

When I first read about Cover I knew it was exactly what I'd been waiting for. We have a section of our back yard that was a steep slope down to the street below. We wanted to do something with it and a guest house (ADU) that could serve as a rental or space for our aging parents seemed ideal. So we took the plunge and paid the small fee to get a series of designs from Cover. They worked with us to refine them and create the perfect space. While they specialize in building prefabs, they also built the retaining wall system and car port our Cover sits on top of. We get as many compliments on the concrete retaining walls as we do the unit itself! Once the unit was complete we were invited to spend the night in our space before the new tenants moved in. Closing the doors, the noise of LA vanished and we were in a perfect, immaculately finished, custom home. If you're thinking of building a small house or studio on your space, these are the folks to talk to.
