According to current code, at least two metal straps must secure the water heater, one placed in the upper third and one in the lower third of the tank’s height.

Inspectors verify that the strapping is tightly fastened to wall studs or other structural members, not just drywall or paneling. Homeowners should be aware that simply replacing an old unit with a new one is not enough; seismic strapping must be brought up to code each time a new unit is installed. For clarity on exact requirements, reviewing Portland’s plumbing permit guidelines can help avoid costly missteps and re-inspections.

Oregon Building Code Requirements For Earthquake Straps

The Oregon Residential Specialty Code outlines statewide standards for securing water heaters, which Portland adopts within its local code framework. These requirements specify the use of heavy-duty straps, commonly galvanized steel or equivalent, installed at both the upper and lower portions of the water heater. The straps must be anchored directly to solid framing, such as wall studs or masonry, to ensure they can resist the shaking forces of an earthquake.

Instructions for proper installation are detailed in the state code, including guidelines for strap tension and the number of fasteners required per bracket. Most manufacturers include installation diagrams, but city inspectors may refer to Oregon seismic safety codes for final judgment on compliance. It’s important for homeowners to confirm that any contractor or installer follows these published standards, as deviations can result in failed inspections regardless of the strap’s appearance.

Insurance providers may also deny claims related to earthquake damage if code-mandated strapping was not in place at the time of the event.

Non-compliance can also delay occupancy or utility service activation after installation.
