While there is no such thing as a standard cost for earthquake retrofitting a home, the average price is usually about 2 to 3 percent of the home’s cost in bay area that makes the range $8000 to $12,000 for your typical home. The cost of repairing a foundation for a typical home after an earthquake could be $25,000 or more. That is at least double the cost of a retrofit. Larger homes, those built on hillsides, and those with basements or rooms over garages will typically cost more to retrofit and will start around $15,000. Many of the average costs mentioned on other websites don’t include drawings, permits and program management with third parties such as EBB (earthquake brace and bolt).

Earthquakes occur suddenly and without warning. The motion on the earth’s crust can cause severe damage to homes. Older structures are especially at risk because many were not built to resist shaking and moving. Strengthening homes may greatly reduce or eliminate damage to a home during these types of natural disasters, and it may also prevent injury and even death.
