Selling in Porter Ranch and worried a small missing part could delay your closing? You’re right to check. The City of Los Angeles requires a seismic gas shutoff valve before a home or condo with gas piping can change hands. This guide explains what the rule means in Porter Ranch, when it applies, how to install the right valve, typical costs, and the exact paperwork escrow needs. Let’s dive in.
In the City of Los Angeles, properties with fuel gas piping must have an approved seismic gas shutoff valve or an approved excess flow valve installed before entering a sale agreement, or before close of escrow if one is already signed. This applies to single family homes, condos, and multi family buildings in Porter Ranch. You can review the city rule in the Los Angeles Municipal Code and its technical requirements for devices, installation, and warranty. See the city’s ordinance for details on the requirement and scope at the Los Angeles Municipal Code Section 94.1217.
The requirement applies to any building with fuel gas piping at the time of sale, including the gas piping that serves each condominium unit being sold. If the valve is missing or noncompliant, it must be installed or corrected before close of escrow. See the city language on timing and condos in the Los Angeles Municipal Code Section 94.1217.
There are limited exceptions. Valves installed before September 1, 1995 may remain if they have been maintained. Certain government or public utility facilities can qualify for exemptions, and some upstream installations are allowed only if they meet strict code requirements. Review exceptions and placement allowances in the Los Angeles Municipal Code Section 94.1217.
Here is a common flow that keeps your sale on track:
Order the city transfer report. Sellers typically request the City of Los Angeles “Requirements When Selling” report early. It lists items that must be met, including the seismic shutoff valve. You can order this through the Los Angeles Department of Building and Safety’s Requirements When Selling page.
Hire a licensed installer and confirm placement. A qualified contractor checks if you already have a compliant device and installs one if needed. By utility policy, valves must be installed on the house side of the gas meter. Devices on SoCalGas-owned piping are not allowed. See SoCalGas guidance on placement and service policies at About Earthquake and Excess-flow Valves.
Pull permits and schedule inspection. Work often needs a permit and a city inspection. After approval, you will receive a sign-off or certificate to satisfy escrow. The city’s transfer process outlines this requirement on the Los Angeles Department of Building and Safety’s Requirements When Selling page.
Deliver proof to escrow. Provide the permit and inspection sign-off or Certificate of Compliance, the installer’s invoice showing model details, and manufacturer or DSA documentation that the valve is certified. The city’s transfer form includes a seismic valve checkbox; see a sample of Form 9A items at LADBS Form 08-B-9A.
In practice, sellers usually arrange and pay for the valve before close, but it is negotiable in the contract. Because the law requires compliance before entering a sale or before close of escrow, missing valves can delay closing. Build a little time into your escrow timeline to avoid last-minute surprises. See the city’s sale requirement language in the Los Angeles Municipal Code Section 94.1217.
There are two common devices: Earthquake Sensitive Automatic Shutoff Valves and Excess Flow Valves. For residential use, products are certified by the state’s Division of the State Architect. You can confirm certification and learn about product lists on the DSA Gas Shutoff Valve Certification page.
SoCalGas does not allow valves on its side of the meter and no longer installs valves for customers. That change was authorized by the California Public Utilities Commission in Decision 01-11-068. Only SoCalGas or its authorized personnel may operate the utility service shutoff and restore service or relight pilots after a shutoff. Review placement and relight guidance on SoCalGas’s About Earthquake and Excess-flow Valves and see the CPUC decision at Decision 01-11-068.
Los Angeles requires a 30-year warranty for valves installed under this section and ongoing maintenance for the life of the structure. Keep your installation paperwork and reset instructions for future owners. Warranty and maintenance requirements are described in the Los Angeles Municipal Code Section 94.1217.
Typical single family installations in Los Angeles often range from about 400 to 1,000 dollars or more, depending on valve size, site conditions, and permit or inspection needs. Some retrofit providers advertise same-day or next-day installs, but actual timing depends on contractor availability and city inspection schedules. For planning, get written quotes tied to your property conditions. See a market example of cost ranges at GS Retrofit’s service information.
