"They deserve 10 stars. Simply the best in every way. The entire team - Marlyn, Gilbert and Gus - were lovely to work with, even under stress and pressure. Their professionalism was unwavering. We did a complex kitchen remodel with structural changes, and they were thorough and detailed in their work, provided white glove service and kept the project moving, staying ahead of schedule and within budget. They were transparent about change orders and did not nickel and dime us. Although they weren't the cheapest, they weren't the most expensive and were spot on on their original budget and quote. Worth every penny. Communications was terrific, service was 5 star, and the craftsmanship is superb. I would work with them and recommend them at every opportunity. "

"⭐ 1 Star – Unsafe, Unlicensed, and Untrustworthy Contractor I hired Fernando Soto / 360FSC Inc. for an ADU and home extension in Millbrae, and it has been one of the most stressful and costly experiences I’ve ever gone through. From the start, Soto relied on unlicensed workers for critical trades. Electrical work was unsafe and failed inspection — indoor panels were installed outside, wires were left unsecured, and essential safety breakers were missing. Plumbing was just as bad: instead of replacing the pipes as I requested on day one, his crew tied old cast iron, clay, and PVC together, even forcing larger pipes into smaller ones. This caused sewage leaks and backups. Independent inspections later confirmed major issues: Flooring – failed inspection and needs to be completely redone. Foundation – the new extension has already sunk by about 3.5 inches, creating serious structural risks. On top of that, the project stalled for months after May 19th, billing was vague, and Soto even threatened to rip out work I had already paid for. He hides behind a P.O. Box in Belmont instead of a real address, which says a lot about accountability. This contractor cuts corners, uses unlicensed trades, and leaves unsafe work behind. Do not make the mistake I did — avoid Fernando Soto and 360FSC Inc. One more red flag: a glowing “review” on this page was written by Rachel G — who is actually tied to his business. That tells you everything about how much weight to give positive reviews here."

FAQs for addition to existing structure building service projects in Albany, CA

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
