Fault Rupture Zone

Asked by Lg_homebuyer, Los Gatos, CA Thu Jun 30, 2011

Many houses in Los Gatos aren't on the active fault zone (Alquist-priolo maps), but are in the county and city fault rupture zones, which is apparently pointing to potentially active faults. What do these mean in terms of future additions to the house? Do these affect the value of the houses that are in these zones?

Having a home in a fault zone shouldn't affect one's ability to remodel or add on to an existing home. As long as you comply with the local building ordinances and zoning regs you should be able to do just about anything they allow.

Most contractors are aware of seismic building requirements i.e. tie downs, shear paneling, strapping, etc.. Additionally, you must pull permits for most remodeling and all room additions or structural alterations. So right there you have the planning department on your side looking out for your best interest.

As far as living near a fault line? Most of California is in a Zone 4 seismic reach. So if that's a major concern you may want to check with the http://www.consrv.ca.gov/cgs/rghm/ap/Pages/index.aspx or the http://earthquake.usgs.gov/earthquakes/recenteqsww/ to determine where active fault lines are. I believe the Sacramento area is not in a Zone 4 seismic area.

That is a very good question. Most buyers will question these fault zones when making purchasing decisions. Some buyers are more concerned than others.

As for building I suggest you discuss that with your contractor and give a call to the City Building Department.
