Water heater replacement in Los Angeles
Updated · Editorial team; not yet technically reviewed
Short answer
In Los Angeles, a water heater replacement needs a permit from the Department of Building and Safety (LADBS), and California requires every water heater to be strapped against earthquake motion: one strap in the upper third and one in the lower third of the tank, with the lower strap at least 4 inches above the controls.
What's different in Los Angeles
LADBS's guidance requires water heaters to be strapped in at least two places: the upper one-third and the lower one-third of the tank, with the lower strap at least 4 inches above the controls. [1]
Bracing can be done with an over-the-counter water heater restraint kit approved by the California Office of the State Architect. [1]
California law requires water heaters to be braced, anchored or strapped to resist falling or horizontal movement due to earthquake motion. [2]
Earthquake strapping, step by step
Upper strap
Within the upper one-third of the tank, anchored to wall studs.
Lower strap
Within the lower one-third, at least 4 inches above the gas or electric controls.
Approved hardware
Use a restraint kit approved by the Office of the State Architect, or equivalent straps and fasteners into framing.
Flexible connectors
Flexible water and gas connectors let the heater move slightly in a quake without breaking lines.
Why the permit matters in LA
The LADBS inspection confirms the strapping, venting, gas connection and relief valve discharge. A gas water heater that tips in an earthquake can break its gas line and start a fire, which is why strapping is enforced on every replacement. Unpermitted installs can also cause trouble at sale.
Choosing a replacement
Many LA homes are considering heat pump water heaters as the region electrifies; they need space, airflow and an electrical circuit, and still must be strapped. See water heater replacement and our tankless vs. tank comparison.
