Fine Design Build is a third generation, design-build company. We shepherd our clients, working side by side, with architects and engineers that we have long-standing relationships with, pushing design past traditional scope limitations. We navigate through the challenging permitting, involving shorelines development, ECA steep slope areas, wetlands. Permitting can be a huge challenge particularly on waterfront parcels. We are experts at removing obstacles and creatively designing homes with minimal to zero impact to environment. After designing your home, we shepherd you through the challenging environment of building. We are very selective about our team and in our rare circumstance as a company, the general contractor, is onsite performing a good percentage of excavation, storm water management, septic, concrete, framing and finishes. We have a unique approach with full transparency where money is spent. The customer has their foot on the gas petal/brake throughout the entire build.

"Best contractor ever. At Fine Design Build the service received was like none other, quality, craftsmanship, in both work and design. We will be forever pleased with house build that we received."

Earthquake Retrofitting questions, answered by experts

According to the Earthquake Country Alliance—a public and private alliance in California that works to improve earthquake and tsunami readiness—reports that unreinforced masonry, such as stone, bricks, and hollow clay tiles, is more susceptible to earthquake damage. The mortar between bricks isn’t as stable as other building materials and methods.

Depending on where you live, your insurance company may require you to have a seismic shut-off valve. It depends on local regulations along with the specific provider. If it’s not a requirement, many providers will offer a discount if you install an earthquake valve, which can save you 5% or more. Contact your provider to learn about potential savings for your plan.

Almost all new buildings in California need an earthquake shut-off valve. The requirements for an earthquake gas shut-off valve (and who can install it) depend on where you live. For example, according to the Los Angeles Municipal Code, you’re required to hire a licensed contractor to install one whenever you build, sell, or renovate a home. Check with your local building department for your city’s laws on installing, permitting, and inspecting earthquake shut-off valves.

Projects will vary based on size and scope, but an average earthquake retrofit takes between two weeks and two months. This includes the initial evaluation and plan, bidding and contract paperwork, permitting and approval process, actual work, and final inspection. Your contractor should give you a more accurate time estimate for your specific project, and they may be able to estimate how long the permitting process will take for your area.

Hearing or feeling vibrations in your house can be unsettling, but there are a few possible causes for a vibrating noise in your wall or floor. Light bulbs and fixtures, circuit breakers, loose pipes, or faulty wiring could all cause vibrations. If you’re not sure what’s causing the vibrations, you can call a contractor to assess your home and narrow down the cause.
