Residential building shall mean any single-family dwelling, duplex, apartment building, condominium, townhouse, lodging house congregate residence, hotel, or motel. Seismic Gas Shutoff Valve shall mean a system consisting of a seismic sensing means and actuating means designed to automatically actuate a companion gas shutoff means installed in a gas piping system in order to shut off the gas downstream of the location of the gas shutoff means in the event of a severe seismic disturbance, The system may consist of separable components or may incorporate all functions in a single body. The terms “Seismically Activated Gas Shutoff Valve” and “Earthquake Sensitive Gas Shutoff Valves” are synonymous. Upstream of the Gas Utility Meter shall refer to all gas piping installed by the utility up to and including the meter and the utility’s bypass tee at the connection to the customer owned piping.

The alteration or addition is valued at more than $10,000 and the building permit for the work in residential buildings including condominium units, is first issued on or after January 10, 1998. Alterations or additions to an individual unit shall require seismic gas shutoff valves to be installed for all gas piping serving that building. SEC. 94.1219.2.3. Building or structures which contain fuel gas piping, that are sold shall have seismic gas shutoff valves installed within 12 months of sale. The sale of an individual condominium unit in a building shall require the installation of seismic gas shutoff valves for all gas piping serving that building if the building has a single gas line. If the building in which the condominium unit is located has multiple gas lines then the valve only required on the line serving the condominium unit and any other condominium unit in the same building. EXCEPTIONS: (1) Seismic gas shutoff valves may be installed upstream of a gas utility meter provided they meet the requirements of this section.

(a) That the building or structure is owned, operated, and maintained by a governmental entity or public utility; or that the building or structure is owned by a private concern and provides a public benefit, such as a co-generation facility which shares its excess power with a public utility or with large industrial facility which has governmental contracts; (b) That the building or structure has available 24-hour, year-round, maintenance staffing; and (c) That the gas piping system contained in the building or structure is designed to withstand seismic effects of earthquakes.

(4) A single seismic gas shutoff valve may be upstream of the gas utility meter at the discretion of the gas utility. SEC. 94.1219.3. General Requirements. Seismic shutoff valves installed either in compliance with Section 94.1219.2, et seq., or voluntarily with a permit issued on or after September 1, 1995, shall comply with the following requirements: SEC. 94.1219.3.1.
