Placer County Homeowners: New Water Heater Seismic Strapping Requirements Could Save Your Home in the Next Big Earthquake

When the ground starts shaking in California, your water heater can quickly become a dangerous projectile—or a lifesaver. The updated code requires dual-strap anchoring systems for all water heaters over 30 gallons. The straps must meet new strength standards and connect to approved structural elements within the building. For Placer County residents planning water heater installations in 2025, understanding these enhanced earthquake safety requirements isn’t just about compliance—it’s about protecting your family and property when the inevitable happens.

What’s Changed in 2025: Stricter Strapping Standards

California has strengthened its water heater seismic requirements for 2025, building on decades of lessons learned from major earthquakes. The new laws regarding strapping help to keep the tanks in place and strapping types and attachment hardware rules have been upgraded for safety since the Loma Prieta quake of 1989 and the Northridge earthquake of 1994. The current regulations require more robust anchoring systems that can better withstand the horizontal forces generated during seismic events.

All new and replacement water heaters, and all existing residential water heaters, shall be braced, anchored, or strapped to resist falling or horizontal displacement due to earthquake motion. This means whether you’re installing a brand-new unit or replacing an aging system, your water heater must meet current seismic safety standards.

The Two-Strap Rule: Proper Positioning Saves Lives

The foundation of water heater earthquake safety lies in proper strap placement. Water heaters require two seismic straps: one within the top 1/3 of the water heater unit and one at the bottom 1/3. The bottom strap must be at least 4″ from the water heater controls. This positioning prevents both tipping and sliding during earthquake motion.

For larger units, additional requirements apply. The third strap is required for water heaters exceeding 52 gallons and the ends of all straps must be secured to a stud with a minimum ¼- inch x 3-inch lag bolt with a washer. The strapping material itself must meet specific standards—plumbing tape is not permitted as strapping material—ensuring the system can handle the forces generated during seismic activity.

Why Flexible Connections Matter

Beyond strapping, the 2025 requirements emphasize the critical importance of flexible connections. Rigid connectors for the heater gas and water piping must be replaced with flexible connectors. During an earthquake, even properly strapped water heaters will experience some movement. Even if the water heater moves only a small distance, the connectors may break if the connections into the water heater are rigid. The break can cause the water to flood the area or more seriously, cause a gas leak.

Professional Installation: More Important Than Ever

With enhanced requirements come increased complexity. If your water heater is older, you will want to have it inspected by a professional water heater installer to ensure that you have the current and safe strapping that is necessary.

The Hidden Benefits of Compliance

Proper seismic strapping offers benefits beyond earthquake preparedness. After an earthquake the water heater also holds available cooking and drinking water in the event of an extended power outage. A properly secured unit is more likely to remain intact and functional when you need it most.

Additionally, compliance affects property transactions. The seller of any real property containing a water heater shall certify to the prospective purchaser that this section has been complied with. Proper installation protects your investment and ensures smooth real estate transactions.

Special Considerations for Placer County

THE PLUMBING CODE IS QUITE EXTENSIVE; PARTS OF THE CODE THAT MOSTLY APPLY TO EXISTING WATER HEATER REPLACEMENTS IN THE SACRAMENTO, YOLO & PLACER COUNTIES ARE SHOWN BELOW: It shall be unlawful for a person to install, remove, replace, or cause to be installed, removed, or replaced a water heater without obtaining a permit from the Authority Having Jurisdiction. Some areas of California do not require a permit. Placer County residents should verify local permit requirements before beginning any water heater work.

The county’s proximity to active fault lines makes proper seismic installation particularly crucial. Earthquake strapping a water heater is critical in California, where earthquakes are a regular occurrence. From Los Angeles and San Diego, to San Francisco and Sacramento, earthquake damage in homes and businesses can happen without warning, and most of us don’t think about our water heater’s safety before an earthquake.

Looking Ahead: Investment in Safety

The enhanced 2025 requirements represent California’s continued commitment to seismic safety. With proper earthquake strapping, your home will be much less likely to be devastated by an unfortunate water heater issue due to earthquake tilting. While the upfront investment in proper installation may seem significant, it pales in comparison to the potential costs of gas leaks, flooding, or structural damage from an unsecured unit during an earthquake.

For Placer County homeowners, the message is clear: don’t wait for the next big one to ensure your water heater is properly secured. Whether you’re installing a new system or upgrading an existing one, compliance with 2025 seismic strapping requirements isn’t just about following the law—it’s about protecting what matters most.
