The Ultimate Guide to Seismic Upgrades
If you live in an area like California where earthquakes and other seismic activity are common, it’s important that you take special precautions to ensure your home or building is properly built to withstand damage. In this guide, we’ll discuss some of the top seismic upgrades building owners and homeowners should consider.
What Are Seismic Upgrades?
A seismic upgrade is a type of renovation that is designed to make a structure more resistant to seismic activity, such as earthquakes. The purpose of a seismic upgrade is to increase the safety of the occupants and to minimize damage to the structure in the event of an earthquake.
Who Needs Seismic Upgrades to Their Home or Building?
Seismic upgrades may be necessary for a structure if it is located in an area that is at risk of earthquakes. The need for seismic upgrades will depend on a variety of factors, including the age and condition of the home, the type of construction, and the local building codes.
In general, homes or buildings that were constructed before the adoption of modern seismic codes may be more vulnerable to earthquake damage and may require upgrades to improve their safety. Additionally, homes that have suffered damage during previous earthquakes or have been subject to landslides or other geological events may also require seismic upgrades.
Are Home Seismic Retrofits Required?
In some cases, seismic upgrades may be required by law. For example, in California, all buildings constructed prior to 1975 and homes built after 1980 must be evaluated for seismic safety and may be required to undergo seismic retrofitting if they do not meet current safety standards. Other states and jurisdictions may have similar laws or regulations in place.
At the end of the day, anyone who lives in an area that is at risk of earthquakes should consider the potential benefits of seismic upgrades for their home. This can include homeowners, landlords, property managers, and commercial building owners. Upgrading a structure to make it more resistant to seismic activity can help to protect the occupants and minimize damage to the structure, potentially saving lives and reducing repair costs in the event of an earthquake.

Can Earthquake Retrofitting Increase Home Value?
Studies have shown that earthquake retrofitting can actually increase the value of a home by up to 10%. These upgrades help reduce the chance of severe damage that could occur during an earthquake, reducing the cost of repairs and increasing the home’s longevity.
Earthquake retrofitting can also help to qualify a home for insurance discounts. Seismic upgrades can not only help protect your home from damage but also increase its value and even save you money to cover the cost of a seismic retrofit in the long run. Investing in earthquake retrofitting is a smart way to ensure your home remains a safe investment for years to come.
Which Seismic Upgrades Should You Consider?
There are hundreds of steps you can take to better protect your home or building from the potential damage that an earthquake can cause. However, there are three categories of upgrades that you should prioritize.
Let’s take a look at each in further detail.
Strengthening a home’s foundation is an important part of seismic upgrades, as the foundation provides the primary support for the structure of the home. Here are some common ways to strengthen a home’s foundation with seismic upgrades:
- Install additional reinforcement: One common way to strengthen a home’s foundation is to install additional reinforcement, such as steel or concrete. This can help to distribute the weight of the home more evenly and provide additional support in the event of an earthquake.
- Upgrade the footings: The footings are the part of the foundation that rests on the soil and supports the weight of the home. Seismic upgrades may involve upgrading the footings to make them stronger and more resistant to seismic activity.
- Install foundation bolts: Foundation bolts are metal bolts that are anchored into the foundation and connect the home’s frame to the foundation. These bolts help to keep the home from shifting or sliding during an earthquake.
- Add shear walls: Shear walls are walls that are designed to resist lateral forces, such as those that occur during an earthquake. Seismic upgrades may involve adding shear walls to the foundation or to the structure of the home to provide additional support and stability.
- Strengthen the cripple walls: The cripple walls are the short walls that rest on the foundation and support the floor of the home. These walls are often vulnerable to collapse during an earthquake, so seismic upgrades may involve strengthening the cripple walls with additional bracing or reinforcement.
You should consult with a professional contractor or engineer who specializes in seismic upgrades to determine the best approach for your specific situation.
Strengthening a building’s roof is another key part of performing seismic upgrades. Here are some specific steps to consider investing in:
- Install additional bracing: One common way to strengthen a home’s roof is to install additional bracing, such as metal straps or plywood panels. These can be attached to the rafters or trusses of the roof to help prevent the roof from collapsing or shifting during an earthquake.
- Add a secondary roof system: Another approach to strengthening a home’s roof is to install a secondary roof system that is designed to provide additional support and stability. This can include a system of trusses or beams that are installed on top of the existing roof.
- Upgrade the roofing materials: Seismic upgrades may involve upgrading the roofing materials to make them more resistant to damage during an earthquake. This can include using materials like metal or tile that are less likely to crack or break.
- Install roof-to-wall connections: Roof-to-wall connections are metal brackets that are used to connect the roof to the walls of the home. These connections can help to prevent the roof from shifting or collapsing during an earthquake.
- Reinforce the chimney: The chimney is often a vulnerable part of the roof, as it can become detached during an earthquake and cause damage to the home. Seismic upgrades may involve reinforcing the chimney with additional bracing or support to prevent it from collapsing.
3. Plumbing and Gas Lines
Upgrading plumbing and gas lines is another important part of seismic upgrades for a home, as these systems can be vulnerable to damage during an earthquake (and may create a host of expensive and dangerous problems should they become compromised).
Here are some common upgrades:
- Install flexible piping: One common approach to upgrading plumbing and gas lines for seismic purposes is to install flexible piping. This type of piping is designed to bend and flex during an earthquake, which can help to prevent the pipes from breaking or leaking.
- Add earthquake shut-off valves: Earthquake shut-off valves are devices that can automatically shut off the flow of gas or water in the event of an earthquake. These valves can help to prevent gas leaks or flooding that can occur during an earthquake.
- Reinforce pipe supports: Seismic upgrades may involve reinforcing the supports for plumbing and gas lines to make them more resistant to seismic activity. This can include adding additional bracing or reinforcement to prevent the pipes from shaking loose or breaking.
- Relocate pipes: In some cases, it may be necessary to relocate plumbing and gas lines to make them less vulnerable to seismic activity. This may involve moving the pipes to a different part of the home or installing them in a more secure location.
- Upgrade to modern materials: Seismic upgrades may involve upgrading plumbing and gas lines to modern materials that are more resistant to damage during an earthquake. For example, modern gas lines may be made of materials like high-density polyethylene (HDPE) that are less likely to rupture during seismic activity.
