SEISMIC GAS SHUT-OFF VALVE REQUIREMENTS
Revised: January 1, 2001
The Los Angeles
City Council has passed Ordinances which require seismic gas
shut-off valves to be installed on certain
buildings within the City. Seismic gas shut-off valves are
devices designed to automatically shut off the supply of
natural gas to a building to prevent a fire or explosion due
to accumulation of gas within the building in the event of
a major earthquake.
The provisions of
this Ordinance apply to:
-
New buildings
built after September 1, 1995.
-
Commercial
buildings performing additions, alterations, or repairs
with a building permit having a valuation
of greater than $ 10,000, issued after September 1, 1995.
-
Residential
buildings performing additions, alterations or repairs
with a building permit having a valuation
of greater than $10,000, issued after January 10, 1998.
-
All buildings
sold in the City of Los Angeles after February 5, 1998.
(Seismic gas shut-off valves must
be installed within one year from the date of sale.)
The seismic gas
shut-off valve may be installed on the customer side of the
meter, this installation requires a Plumbing Permit
and inspection from the Department of Building and Safety. A
Plumbing Permit may be obtained by an owner/occupier of a
single family dwelling. A Plumbing Permit may be obtained by a
licensed Plumbing Contractor for any type of
building. The cost of a Plumbing Permit for a single valve is
$43.40. To request an inspection, call 1-888-LA-4-BUILD
