California Building Structures handles both commercial renovations and residential electrical work without much fuss. We found 10 reviewers who praised the team's workmanship, and none reported shoddy installations or follow-up issues. One office renovation kept a business running during a gut remodel, with the crew coordinating around open hours. Another customer appreciated that Shannon inspected an aging roof before installing solar and replaced it first, even though high-pressure competitors had ignored the obvious problem. The electrical side moves fast. One technician finished an hour-long job in 30 minutes and charged only for actual time, not the quoted block. But we did spot one review alleging unpermitted work and signature forgery. That's a serious claim, and while it's a single outlier among dozens of satisfied customers, it's worth asking about permits and documentation before signing.
If you want straightforward electrical work or a commercial remodel without drama, this team delivers solid results at fair prices. Just confirm all permits are pulled in writing.
Scotty found himself sorting through bids for a grid-tied solar setup when several high-pressure companies pushed to mount panels on his aging roof, even though it would soon need to be torn off and replaced. CBS took a different path: they inspected the roof first, replaced it in a cost-conscious way, and only then installed a system sized to cover both his current and future electric bills. What stood out most was the math at the end — the combined price of the roof work and the solar system came in below his average power bill, leaving him insulated from future rate hikes.
Glenn found himself with a lot of questions and a same-day electrical appointment, and Brittney kept the process moving from start to finish. She arranged the visit quickly, and the technician, Rodney, turned up prepared, talked through what he was doing, and handled the work with a smooth, efficient pace. What made the visit stand out was the billing: he had been quoted $120 for an hour of labor, but Rodney finished the job in about 30 minutes, so the final charge dropped to $60. Glenn ended up with a quick, clear repair and a surprisingly fair invoice.
Bobby ended up feeling burned by a solar job that came with accusations of inflated charges, permit problems, and paperwork he believed had been handled improperly. What stood out most was the claim that the owner tried to shift responsibility onto him while moving forward without permits and even putting forward a signature he believed was not his.

Manuel was looking to get a solar project wrapped up quickly, and CBS ended up being the easy answer. He came away feeling the price was fair and the workmanship solid, with the job moving fast enough that it stood out as the main selling point. For a project at WBS, that meant getting quality work done without the usual drag of a long install timeline.
Tyler had Shannon and his team step in more than once, sometimes for urgent fixes and other times for longer-running projects, and each time they came through with the same steady attention. What stood out was how they kept both quality and cost in view as if they were protecting his interests, not just closing out a job. That kind of consistent follow-through made their help feel especially reassuring whenever something needed attention.
Scott had the roofs on his buildings sealed by a crew that showed up on time and handled the job with a polished, professional touch. The work itself came out top notch, and they wrapped it up within the estimated timeframe, which made the whole project feel orderly rather than disruptive. What stood out most was how smoothly they moved through a fairly straightforward but important job on commercial-style buildings, leaving him with a contractor he’d bring back for future projects.
Dave Leach brought Shannon and the CBS crew into a major office renovation, the kind of job where every day of disruption can ripple through a business. From the start, Shannon kept the goal simple: get them to the finish line with as little interference as possible. That focus mattered because the scope of the work was large enough to make business continuity a real challenge, yet the team handled it smoothly and kept the office operating throughout the project. In the end, they delivered a standout result at a competitive price, with the renovation wrapped up in a way that let the business keep moving without missing a beat.
Isabella reached out for help with her Generac generator and found Brandon on the other end of the line calm, kind, and already paying close attention. Even over the phone, he came across as genuinely concerned about what was going wrong, and he moved fast enough to get the issue fixed quickly. The standout here was how much care he brought before he ever arrived in person.
Oji had all three ceiling fans installed in a single quick, efficient visit, and Rodney handled the job with an easy, no-fuss touch. What stood out was how smoothly the work moved from start to finish—three fans up and running without wasting time, leaving the home ready for whatever project comes next.
