Earthquake Gas Seismic Shutoffs
As of January 2004, all sellers of residential homes in
California Zone 3 and 4 seismic areas must have a properly
installed earthquake gas shutoff valve installed along with
the required city building permit. This installation must be
inspected by law by a city building inspector. This is done
for your protection.
The Los Angeles City Council has expanded an existing
ordinance that requires all newly constructed homes and
businesses to install an automatic earthquake gas shut-off
valve. Moreover, if you’re making alterations or additions
valued at $10,000 or more, installing an automatic
earthquake gas shut-off valve is by law mandatory.

But forget about the legal requirements for a moment, isn’t
the protection of your family and your home worth worth it?
