An earthquake can turn an ordinary California morning into a continuity problem. Utilities may fail, communications may become unreliable, records can be difficult to retrieve, and a home office may contain enough computers, storage devices, and networking equipment to create both physical hazards and business disruption. A resilient household needs more than a quick reminder to Drop, Cover, and Hold On.
This California Earthquake Preparedness Checklist for Homeowners moves from preparation to immediate response and recovery. It covers documents, furniture, emergency supplies, utility controls, communications, structural assessments, and the digital systems that families and small businesses rely on. It also addresses what to do with electronics affected by impact, water, smoke, or age. Reworx Recycling can help homeowners and organizations plan for secure data destruction, responsible electronics recycling, and appropriate retirement of devices when equipment is no longer safe or useful. For a broader perspective on evaluating service providers, you can also review these reasons to choose Canada, although earthquake decisions should remain grounded in California-specific conditions and official guidance.
1. Secure Your Important Documents and Digital Data Before an Earthquake
A recovery process becomes harder when insurance records, identification, financial files, and business documents exist on only one device or in one room. Start by listing the information your household would need if the home became inaccessible. Include insurance policies, agent contact details, property records, medical information, tax files, banking information, passwords, contracts, and documentation for renovations or major purchases.
Keep physical copies in a waterproof, fire-resistant container, and maintain a separate copy outside the primary residence, such as in a bank safety deposit box. Digital copies should use encrypted cloud storage, such as Google Drive or iCloud with appropriate security settings. Home-based IT consultants and small business owners may also keep encrypted backup drives in a separate earthquake-safe location.
Build a recovery system you can actually test
Automatic backup should run on computers and mobile devices, but an enabled backup isn't enough. Test restoration procedures quarterly so you know the files can be recovered, the credentials work, and the backup device isn't corrupted. A password manager can reduce the risk of losing access to essential accounts during a stressful event.
Keep a printed record of insurance policy numbers, claims procedures, and contact information where a household member can find it quickly. Photograph home improvements and store receipts with property records. These details can help establish what existed before damage occurred.
Practical rule: A backup that has never been restored is an assumption, not a recovery plan.
Computers, servers, and storage devices also need physical protection. Secure them against tipping, keep backup equipment away from likely water exposure, and retire old drives through a documented secure data destruction process. Reworx Recycling explains what data sanitization involves for organizations replacing equipment that may contain sensitive household or business information.
2. Secure Heavy Furniture and Appliances to Prevent Injury and Damage
Heavy furniture can shift, tip, or spill its contents during shaking. California guidance recommends bolting bookshelves to wall studs, bracing water heaters to studs, using flexible gas-line connections, and moving beds away from windows. These steps protect people first, but they also reduce damage to property and equipment.
Walk through each room and identify furniture that could fall across a doorway, block an exit, or strike a bed or work area. A tall bookcase should be attached near its top to a wall stud with suitable brackets. Use a stud finder before drilling, and don't rely on drywall anchors for a load that needs structural support.
Treat the home office as a small equipment room
Home offices often combine desks, filing cabinets, monitors, printers, UPS units, and shelving. Secure heavy cabinets so drawers can't pull the unit forward, place dense equipment low, and brace racks or shelves that could roll or tip. A small business owner should also account for network switches, backup drives, and power equipment, not just the desktop computer.
Water heaters require particular attention. California preparedness guidance calls for strapping them to studs, while flexible connections can reduce stress on utility lines. Refrigerators and other large appliances should have enough flexibility in their connections to accommodate limited movement without pulling on pipes or cables.
Inspect brackets, straps, and fasteners regularly for corrosion, looseness, or deterioration. Renters can use approved restraint systems that don't damage the property, while complex installations, server racks, and unusually heavy equipment deserve professional review. During an office move or equipment transition, professional office relocation support can help keep bulky assets from becoming unsafe stored items.
3. Create and Maintain an Earthquake Emergency Supply Kit
A power outage, blocked road, or damaged water line can leave a household without normal services. Build an emergency kit around a three-day survival baseline, including three gallons of water per person and at least three days of nonperishable food. Add a manual can opener, battery-powered or hand-crank radio, flashlight with extra batteries, first aid kit, prescription medications, cash, copies of critical documents, whistle, local map, phone chargers or power banks, plastic sheeting, duct tape, and a wrench or pliers for utility shutoffs. The California earthquake readiness guide provides the full preparation framework.
Water is often the gap between having supplies and being able to manage an extended interruption. A California survey found that more than 80% of households kept first aid kits, flashlights, and batteries, while only 40% stored the recommended minimum of three gallons per person (California Office of Emergency Services survey data). Check stored water directly rather than assuming a stocked kit covers the household.
Distribute supplies for access and continuity
Use waterproof containers and place kits where everyone can reach them. Several smaller kits may be easier to carry than one heavy container, particularly if occupants must shelter in different rooms or leave quickly. Keep separate supplies for the home, workplace, and vehicles.
Tailor each kit to household needs. Include dietary items, medical supplies, protective gloves, and relevant documents. Home-office workers should add a power bank, charging cables, written computer shutdown instructions, and a paper list of critical contacts. Businesses with multiple locations should assign a coordinator and maintain an inventory at each facility.
Review food, medications, batteries, and power equipment on a schedule. Do not place expired lithium batteries or obsolete power equipment in ordinary trash. Reworx Recycling explains lithium battery recycling and responsible handling options for retired electronics. That process keeps damaged or outdated devices out of household waste while supporting safer recovery and replacement planning.
4. Know How to Shut Off Utilities and Locate Shut-Off Valves
After shaking stops, inspect the situation before touching utilities. A damaged gas line, broken water pipe, or compromised electrical system can create serious hazards. Every capable household member should know where the gas, water, and electrical shutoffs are located, what tool is needed, and which conditions require a call to the utility provider or emergency services.
Mark shutoff locations clearly. Keep an appropriately sized wrench beside the gas meter, not buried in a toolbox across the house. Label the electrical panel so family members can identify circuits, and photograph the controls for reference. Written instructions belong in the emergency kit because a phone may be damaged, uncharged, or unavailable.
Practice the sequence without creating new risk
Practice locating the valves and panel, but don't manipulate systems in a way that could damage them. Gas shutoff procedures deserve special care because the utility company generally needs to restore service after the valve has been closed. If you smell gas or suspect a leak, leave the area and call 911 from a safe location. Don't use switches, flames, or devices that could create an ignition source near a suspected leak.
Water shutoff knowledge can limit flooding if pipes break. Electrical awareness helps prevent contact with energized equipment after water intrusion. Homeowners should also understand which systems are supplied by shared building infrastructure, especially in apartments and condominiums.
For a home office or small business, utility planning includes safe shutdown of computers, servers, networking systems, and cooling equipment. Document who can shut down systems, where the procedure is stored, and how the business will avoid restarting damaged hardware. A facility manager should coordinate IT procedures with building-level emergency controls rather than treating them as separate plans.
5. Identify and Secure Potential Hazards in Your Home and Office
A room-by-room hazard assessment reveals risks that are easy to overlook during ordinary life. Look above eye level, behind doors, inside storage areas, and around workstations. Heavy objects on high shelves, unsecured mirrors, glass artwork, hanging fixtures, unstable cabinets, and exposed chemicals can injure people or complicate recovery.
California's official preparedness guidance organizes household action around identifying hazards, creating plans and kits, inspecting building weaknesses, protecting yourself during shaking, and checking injuries and damage afterward (California earthquake preparedness guidance). Use that sequence as a practical audit rather than limiting preparation to supply shopping.
Include technology and hazardous materials
A home office assessment should cover monitors, printers, external drives, desktop towers, battery backups, cables, and shelving. Secure servers and computers so they can't roll or tip, move heavy equipment lower, and keep data-bearing devices away from likely falling objects or water sources. A damaged device may present electrical, battery, or data-security concerns even when its exterior appears intact.
Photograph each hazard and rank corrections by likely consequence. Move heavy items from high shelves, attach mirrors and artwork with appropriate fasteners, and replace unstable storage with lower, secured alternatives. Examine ceiling tiles and fixtures, and review hanging lights where a safer configuration is practical.
Chemicals, cleaning products, laboratory equipment, and other breakable materials require separate attention. Store them so a fallen container won't block an exit or contaminate electronics. If a device has been exposed to smoke, water, or impact, isolate it and avoid powering it on until a qualified professional assesses it. Retired equipment should enter an appropriate IT equipment disposal or electronics recycling process, not an informal pile in a garage.
6. Develop a Family Communication and Reunification Plan
Phone networks may be congested, electricity may fail, and household members may be at school, work, or on the road when an earthquake strikes. Set the out-of-state contact, primary meeting location, backup location, and status-reporting method before an emergency. Put children's contact details on an ICE card in their backpack or wallet.
Choose a primary meeting place by address, then select a secondary site if the first is damaged or inaccessible. A neighborhood park, school campus, or familiar public location may be suitable. Check each site for falling structures, broken glass, fire, flooding, and damaged utilities before assigning it.
Write the plan for a stressful moment
Keep printed copies at home, at work, and in emergency kits. Include phone numbers, email addresses, medical information, school pickup instructions, pet responsibilities, and directions for leaving a voicemail with the out-of-state contact. Text messages may work when voice calls fail, so agree on a brief format that states who is safe, where they are, and what help they need.
Businesses need a parallel workforce plan. Managers should define employee check-in procedures, assign responsibility for accounting for each team, and document how essential work will transfer if the workplace becomes unsafe. Home-based businesses should separate family reunification from client communication. Prepare a written notice explaining how operations will continue during an outage, including how remote work, data access, and customer updates will be handled.
Low-tech tools remain useful. A prearranged message-board location, printed contact tree, battery-powered radio, and paper map support decisions when mobile devices fail. Store the plan with important documents, and review it when addresses, schools, workplaces, medical needs, or household responsibilities change. California's Seismic Safety Commission advises registering for earthquake early-warning alerts and keeping emergency information on paper (California Seismic Safety Commission preparedness guides).
7. Conduct Regular Earthquake Drills and Update Preparedness Plans Annually
A plan is useful only when household members can follow it under stress. During each drill, practice Drop, Cover, and Hold On, find emergency supplies, identify utility controls, and confirm how everyone will communicate after the shaking. Check for practical failures, such as a blocked kit, missing charger, inaccessible document safe, or unclear responsibility for pets and children.
California households have reported preparedness gaps, so written plans need regular practice and review. Update the plan when household needs, work arrangements, or equipment change.
Test recovery, not just reaction
Include the home office and any small business operation. Practice shutting systems down safely, identify equipment that must stay powered, verify that backups can be restored, and record how work will continue if the primary workspace is unavailable. Test data recovery on a schedule and document the results, including failed steps that need correction.
Use varied scenarios during the year. One drill can address sheltering at home, another separation during commuting, and another a prolonged loss of power or internet access. Time the search for supplies and the contact process, but use the result to find bottlenecks rather than to rank household members.
After each exercise, record gaps and assign an owner to every correction. Replace expired food, medications, and batteries. Update contact details and floor plans, remove obsolete equipment from the emergency setup, and confirm that sensitive devices and records remain protected.
Retired or damaged electronics should not return to service without an assessment. Set aside devices for secure handling, preserve required data-protection procedures, and use Reworx Recycling's training and education resources to build practical habits for equipment handling, data protection, and responsible technology retirement. Revisit the checklist annually and after any major household or business change.
8. Work with Professional Assessment Services and Stay Informed About Structural Improvements
Supplies and drills cannot correct a weak connection between a house and its foundation. Begin with a structural inspection, then address documented risks through appropriate retrofitting and a family emergency plan. Older homes, additions, crawl spaces, and properties with visible foundation or framing concerns deserve particular attention. California homeowners can review California Earthquake Authority information when considering common brace-and-bolt approaches.
Retrofit requirements depend on how the house was built and the foundation it uses. Brace-and-bolt work may involve securing the house to its foundation and adding bracing around the crawl-space perimeter. A generic hardware kit may not suit every structural condition, so obtain an assessment before choosing materials or starting work.
Use qualified assessments and documented priorities
Contact the local building department about permits, retrofit resources, and local programs. For major work, consult a licensed structural engineer and contractors with seismic-retrofitting experience. If the proposed project is extensive, compare professional opinions and rank corrections by documented risk, not appearance or sales pressure.
Keep permits, engineering notes, invoices, photographs, and completion records with your insurance documents. Revisit the assessment after a property change, major renovation, or new information about building risk. Include IT and facilities professionals when the property supports a home office or small business. Their review should cover equipment anchoring, server-room layout, cooling dependencies, power needs, and plans for continuing work if the primary workspace is unavailable.
Physical safety and technology handling require the same care in vendor selection. Before transferring storage devices or damaged electronics, review vendor selection criteria for responsible equipment handling and confirm how data-bearing equipment will be handled. For another perspective on evaluating a property's physical condition, consult this Firm Foundations home assessment. Keep damaged devices separate until their condition, data-protection requirements, and recycling or disposal path are documented.

Turn Preparedness Into a Recovery Routine
A useful earthquake plan isn't a binder that disappears onto a shelf. It's a maintenance routine that connects physical safety, household communication, financial documentation, technology continuity, and responsible recovery. Start by securing furniture, appliances, water heaters, shelves, monitors, racks, and other hazards. Then verify that everyone knows where the emergency kit, document copies, utility controls, and paper contact information are stored.
Refresh the kit on a schedule. The official California checklist calls for three gallons of water per person, nonperishable food, a manual can opener, radio, flashlight, first aid supplies, medications, cash, critical documents, a whistle, map, chargers or power banks, plastic sheeting, duct tape, and tools for utility shutoffs (California earthquake readiness guidance). A kit should reflect the household's actual needs, including prescriptions, dietary requirements, mobility concerns, pets, and home-office responsibilities.
Review backups and communications as carefully as physical supplies. Keep insurance information and property records in both protected paper form and secure digital storage. Test restoration procedures, confirm that passwords remain accessible, and make sure family members and employees understand how to check in. California research also found that more than 60% of residents reported learning basic earthquake safety, supplies, and household-content protection, while fewer than 35% had learned how to make the home's structure safer or safeguard finances (California preparedness survey). That difference shows why recovery planning must extend beyond immediate survival actions.
Electronics need a clear post-quake protocol. Devices exposed to impact, water, smoke, or unstable power should be isolated and kept away from people until they can be evaluated. Don't casually reconnect a wet laptop, swollen battery, damaged power supply, or smoke-exposed server. Data-bearing equipment should go through secure data destruction before disposal, resale, donation, or recycling when the data cannot be safely retained.
Usable equipment may support donation programs or technology reuse. Obsolete hardware may require computer recycling, laptop disposal, or broader IT asset disposition services. Businesses managing an office cleanout, facility cleanout, data center decommissioning, medical equipment disposal, laboratory equipment disposal, product destruction, or a corporate donation program should document the chain of custody and separate reusable assets from damaged materials.
Reworx Recycling is a donation-based social enterprise recycling partner that helps organizations and individuals approach electronics recycling, IT equipment disposal, data destruction, and equipment retirement with environmental responsibility and community impact in mind. Its mission includes technology donations, digital inclusion, and workforce development, while its published resources help businesses plan e-waste drives, office recycling programs, reverse logistics, and ITAD initiatives. That makes responsible electronics handling part of the same resilience plan as structural inspections and emergency communications.
Preparedness improves when each task has an owner and a review date. Secure the hazards, inspect the structure, refresh supplies, test backups, practice communications, and record what should happen to damaged or obsolete devices. A household or business that follows that cycle is better positioned to protect people, preserve information, resume essential work, and keep electronics out of improper disposal channels after the shaking stops.
Reworx Recycling helps homeowners, offices, schools, agencies, and businesses manage electronics recycling, secure hard drive destruction, equipment decommissioning, donation-based recycling, and responsible IT asset disposition.
