What state law and the regional water district say to rental owners
California Health and Safety Code section 19211 requires all new, replacement and existing residential water heaters to be braced, anchored or strapped to resist falling or shifting in an earthquake. In California's water heater bracing law, the Legislature found that renters are not authorized to strap, brace or anchor the water heater in their unit without the owner's advance approval.
The Metropolitan Water District's SoCal WaterSmart rebate program takes applications for single units under its residential program. Applications for five or more units under a single water meter, and for landscape or outdoor measures or devices for a multi-family property's common areas, must go through its commercial program instead.
