Does Your Manufactured Home have Earthquake Bracing?

California, specifically the Bay Area, felt quite a rumble in January. The New Year started with a 4.4 magnitude in Berkeley along the Hayward Fault, which lasted about 10 seconds. An estimated 9.8 million people in the Bay Area felt the aftershocks of the quake, leaving them to question whether they are ready for when the “big” earthquake hits California.

The quake was a reminder that there is a one-in-three chance that a 6.7 or greater earthquake will hit the Bay Area in the next 30 years, according to the United States Geological Survey.

While the state of California’s Residential Mitigation Program offered grants of up to $3,000 for seismic retrofits of older homes, one of the most asked questions regarding manufactured homes are whether they are safe from earthquakes.

“Manufactured homes fair very well during earthquakes,” said Ara Sarkisian, a partner in Alliance Manufactured Homes. “They are built with a high percentage of shear walls, which offers great structural support during any shaking or rattling from an earthquake.”

Compared to on-site built homes, manufactured homes are lighter in general, an advantage in the context of earthquake ground motion, as seismic forces are proportional to the weight of architectural structures. These factory-built homes are built to resist the severe forces and shaking when transported on a permanent chassis from factory to site. The seismic performance of manufactured homes depends largely on the condition of the foundation and particularly on the connections between the home and the foundation, in accordance with Arash Nasseri, Ph.D. and Ehsan Kianirad, Ph.D. of ‎AIR Worldwide.

With Pier Approval by the State of California Department of Housing and Community Development, manufactured homes are installed onto a series of steel support piers, one of the most used earthquake restraint bracing systems (ERBS).

The piers offer structural foundation and seismic bracing for any lateral forces caused by earthquakes. It is also important to secure the piers to their footings and main beams of the home, as shown below (Fig 2). These connections will prevent the home from jumping off the pier or footing during an earthquake.

Alliance Manufactured Homes Installations has installed 75% of the new manufactured homes in the Greater Bay Area, accredited with over 5,000 new home installations. They are now offering earthquake bracing for any size home at the low flat rate of $1,995.

Location, location, location! Paradise Cove in Malibu California gives a whole new meaning to mobile home communities. Not only is this oasis notorious for its breathtaking canyons, nearby sea, and warm weather, but it is the home of multi-million dollar manufactured homes. Celebrities such as Matthew McConaughey, Pamela Anderson, and Minnie Driver once called this community their home. It was also a popular location for film sets such as the Beach Boys’ Surfin’ Safari record. So what does it cost to live in this beach friendly community?

David Carter, a real estate agent in Malibu says one home sold for $2.5 million in 2011. “Paradise Cove is full of gorgeous, tricked-out residences with a lot of value. It’s hard not to fall in love with this place”, Carter explains.

It is not uncommon to find luxurious features such as sub-zero appliances, recessed lighting, marble floors, and granite counters in some of these homes. So next time you’re thinking of moving you may want to consider Paradise Cove. When you’ve got the warm weather and a beach what’s not to love?

Happy Valentine’s Day!

Valentine’s Day is observed on February 14th in honor of Saint Valentine. There are many legends about the mysterious figure yet, none are for certain. Some say he was a priest who married young couples in secret from the Roman Emperor of his time who was opposed of the idea of young soldiers getting married because he thought single soldiers performed better in battle. Other legends say he fell in love with a woman while in prison and sent a love letter, and the first Valentine signed, “Your Valentine”. Cupid is another symbol of Valentine’s Day. According to Roman mythology he is the goddess of love and shoots magical arrows at those he wishes to fall in love. Today, Valentine’s Day is celebrated worldwide and includes heart shapes, doves, and the giving of flowers, candy, and cards.
