"Our experience is identical to what other reviewers shared. And yes, you should run from this company as fast as you can. Do not buy what Abraham shared that the payment must be made when the inspection is passed. Check the Business and Professions code yourself, the payment only needs to be made when the job is completed. It is very COMMON that the job is not even done or poorly performed even the inspection is passed. Here are the issues that multiple families including us run into with this company:: The project was delayed for over 9 months. No one manages the job. He often employs young men from his own Jewish community. They are enthusiastic but had no prior experience. The worse part is that they don't get paid. Two of them even set up a new construction business knowing Abraham will never pay them. Subcontractors can put your house on lien also. Many reviews you see on Yelp, Google, Angi are NOT genuine. Even the references are fake with hindsight, we were given 2 references. One reference shared the exact same accent as the PM. The other reference was initially happy with their work, but then reached out to us and shared a similar horror story with them like what we experienced. You will lose a lot of $$$ on materials as the subcontractors will somehow leave a thousand dollars worth of quartz at home. Maybe they want to compensate for the money Abraham owed them? Let me tell you, reordering materials is not fun."

"Oscar truly stands out as a contractor who cares deeply about his clients, and that’s exactly how he made me feel. I reached out to five different contractors to assess my bathroom and offer ideas, but my experiences varied significantly. Some were overly sales-driven, others dismissed my ideas entirely, and one didn’t even follow up with an estimate. Oscar, however, was a breath of fresh air. He arrived on time, listened attentively to my ideas, and offered thoughtful suggestions. He was highly collaborative with the other workers on site, making sure everything was well coordinated. Oscar's expertise in the industry is evident, and he’s exceptionally creative when it comes to problem-solving. When he identified additional challenges during the project, he took the time to offer practical solutions, demonstrating his commitment to delivering the best result. Oscar has earned my trust and will be my go-to contractor for any future projects. I highly recommend him to anyone in need of a reliable, skilled, and dedicated professional"

"⭐ 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 shelter or outbuilding building service projects in Berkeley, CA

A bomb shelter is an abode built to withstand disaster. Bomb shelters may refer to a space or bunker that can protect inhabitants through a hypothetical nuclear attack, apocalypse, or any other massive crisis. People usually build bomb shelters underground and stock them to live there a few days to a month at a time. Doomsday bunkers accommodate long-term living rather than just through a short crisis.

Builders construct bomb shelters with reinforced steel, box culvert, concrete, or other durable materials (but many professionals do not recommend shipping containers, as they’re not designed to live underground. If building underground, you’ll first have to excavate land before building the actual structure. You’ll have to implement air and water filtration systems, septic systems, and power supply.

It takes a lot of experience to safely and legally construct a bomb shelter, not to mention make sure it’s fit to live in for extended periods of time. It’s best to talk to a residential structural engineer near you for proper guidance.

The current standard filtration systems require filtering both air and water. For air, you’ll want an NBC filter system, which both domestic and international producers make. NBC stands for Nuclear, Biological, and Chemical, which filters out all three. If you’re only building your shelter for natural disasters, chemical attacks, and biological attacks, you may opt for the less expensive HEPA filter system. 

Water filtration requires the same level of care. You’ll likely want to have a large water storage capacity to survive short-term disasters. For long-term living, you’ll want to have a water filtration system.

Rising S bunker prices depend on the size, ranging anywhere from $20,000 to $9 million. Their least expensive model is 96 square feet while their most expensive model has a gym, swimming pool, hot tub, and bowling alley.

  • Mini: $45,500

  • Standard Bomb Shelter: $67,500–$109,500

  • Silver Leaf: $140,000–$182,500

  • Admiral: $180,000–$500,000

  • Xtreme: $450,000–$780,000

  • Xtreme Bunker Complex: $840,000–$1,830,000

  • Luxury Series: $3,800,000–$9,600,000

You almost always need a permit to build a bunker on land with any type of public utilities running through it. You’ll want to check with your local building code enforcement agency to see if this is the case for your area. 

Because you’re building a structural component that often requires electricity, water, and sewage services, you’ll need to apply for permits to attach these utilities to your new property. However, off-grid-only units in rural areas may not need all or any of the permitting you’d normally find in more urban settings.

To survive a nuclear blast, you’ll need to have your bunker at least three feet underground. However, it’s usually advisable to put it further underground. To survive a close strike, you’ll want to have the bunker at least 10 feet down and with five-foot thick reinforced concrete. However, knowing exactly how deep to build depends on the size of the blast you’re trying to avoid. Most bunkers don’t need to be more than 5 feet below the ground.
