If you are buying or selling a home built before 1960 in California, you’ll likely have to get or complete a form regarding earthquake hazards at the home (some people / situations are exempt) called the Residential Earthquake Hazards Report. The is written and mandated by the State of California. Question # 7 asks about homes with a living space over a garage – this is referencing soft story construction. Many home buyers and sellers would benefit from understanding all of these questions and why the responses matter for earthquake safety. Today we’ll focus on the seventh one.

Soft story construction can also related to office buildings or store fronts on the first floor with large windows or doors rather than solid walls and more floors above it.

The danger arises from the lack of sheer wall in case of a quake. The all glass windows on the first floor, or big carports or garages, are simply not as strong as a wall, and may give way in the case of shaking. For that reason, many are bolstered or reinforced. I wrote about it earlier this week in my Move Move2SiliconValley blog, please read more there: Is your home safe in an earthquake?
