How to Build a California Go-Bag That Will Actually Get You Out the Door
What should I put in a California earthquake or wildfire go-bag?
A California go-bag should include at least three days of water (one gallon per person per day), non-perishable food, copies of important documents in a waterproof container, cash in small bills, a first-aid kit with any prescription medications, an N95 mask, a flashlight, a battery-powered radio, a portable phone charger, and sturdy closed-toe shoes. Tailor it to your household's specific medical or dietary needs.
How much water should I store in a go-bag for an emergency?
Cal OES and FEMA recommend at least one gallon of water per person per day for a minimum of three days, so a two-person household should plan for at least six gallons. Because that's heavy, water purification tablets or a portable filter are widely accepted alternatives for a go-bag, as long as you also know where to source water at your destination.
How do I find my wildfire evacuation zone in California?
Evacuation zones in California are managed at the county level, so the best starting point is your county's Office of Emergency Services or Sheriff's website. CalFire's website at calfire.ca.gov provides fire hazard severity zone maps and links to local county resources. Knowing your zone number or letter in advance matters because evacuation orders are typically issued by zone, not by street address.
How often should I update my emergency go-bag?
Cal OES recommends reviewing your emergency kit at least once a year. A practical approach is to do it on the same schedule as changing smoke alarm batteries. Check water and food expiration dates, replace expired medications or those with updated prescriptions, and make sure any battery-powered devices and power banks are still functional and charged. Update the bag any time your household changes.
Do I need an N95 mask in my go-bag for California wildfires?
CalFire recommends N95 respirators or better for wildfire events because wildfire smoke contains fine particulate matter that standard cloth masks don't adequately filter. An N95 rated mask, properly fitted, provides meaningful protection during smoke exposure. Include one per person in your go-bag if you live in or near a fire-prone area, and check periodically that stored masks haven't degraded.
When a wildfire evacuation order drops at 2 a.m. or a major earthquake severs utilities across your neighborhood, the difference between a smooth exit and a chaotic scramble often comes down to what you packed before the emergency started. Cal OES and CalFire both recommend having a go-bag ready to grab in under two minutes, but most guidance on what to put in one is vague enough to be nearly useless. Here's what you actually need, based on official state and federal emergency management recommendations.

The Core Supplies: What Goes In First
Water is the non-negotiable foundation. FEMA and Cal OES recommend at least one gallon per person per day, for a minimum of three days. For a two-person household, that's six gallons, which is heavy, so a practical alternative is several one-liter bottles plus a quality water filter or purification tablets, which the American Red Cross also endorses for go-bag use.
Food should be non-perishable and require no cooking or refrigeration. Granola bars, nut butter packets, dried fruit, and sealed crackers work well. Pack enough for at least 72 hours. If you have an infant or a pet, that means formula or pet food as well, enough for the same window.
Documents are where most people underpack. A waterproof bag or sealed plastic envelope should hold: copies of your driver's license, passport, insurance cards (home, auto, and health), the deed or lease to your property, Social Security cards, and, if relevant, custody agreements or medical directives. Keep a small amount of cash, in small bills, since ATMs often go down after a disaster. A USB drive with scanned copies of these documents adds a second layer of protection.
Medical and Safety Supplies
A standard first-aid kit is the baseline, but tailor it to your household. If anyone takes prescription medication, a three-to-seven day supply should rotate through the bag regularly so it doesn't expire. Include a list of current medications, dosages, and the prescribing physician's contact information on paper, not just in your phone. Glasses or contact lens supplies belong here too, along with any medical devices like a blood glucose monitor, extra batteries, and chargers.
For a wildfire evacuation specifically, the California Department of Forestry and Fire Protection (CalFire) recommends an N95 respirator or better. Smoke inhalation is a serious risk during and after a wildfire event, and a cloth mask provides minimal protection against fine particulate matter. Goggles are also worth including if you have them.
For earthquake situations, where shelter-in-place may be necessary before you can leave, add a pair of heavy work gloves and sturdy closed-toe shoes stored near the bag. Broken glass is one of the leading causes of post-quake injury. A whistle, a flashlight with extra batteries, and a hand-crank or battery-powered radio round out the safety tier.
Communication and Power
Your phone will be essential, but cell networks frequently saturate or fail after a major earthquake or during a large evacuation. Pack a portable battery charger (power bank) that's kept charged, and a car charger as a backup. A battery-powered or hand-crank NOAA weather radio lets you receive official updates even when cell service is out; the Cal OES-endorsed Wireless Emergency Alert system uses cell broadcast rather than standard data, so those alerts often get through when regular calls won't, but having a radio is a true fallback.
Write down key phone numbers on paper. Include at least one out-of-state contact, since it's often easier to reach someone outside the affected region during a local disaster than to call across town. The American Red Cross and FEMA both recommend designating an out-of-area contact as a family communication hub.

Wildfire-Specific Additions
If you live in or near a State Responsibility Area (SRA) or a local government Very High Fire Hazard Severity Zone, CalFire's official guidance suggests keeping your go-bag near the exit most likely to be your route out, not necessarily the front door. Have a plan for at least two evacuation routes from your home and know which zone you're in, since evacuation orders frequently use zone designations rather than street addresses. Your county's Office of Emergency Services website is the right place to look up your specific zone; CalFire's website at calfire.ca.gov provides maps and links to local resources.
Keep a pair of clothes for each person in the bag, including long sleeves and long pants made from natural fibers like cotton or wool, not synthetic materials that can melt. Closed-toe shoes for everyone are essential. If you live with elderly family members or people with mobility limitations, plan now for how they get out and whether any specialized equipment needs to be pre-staged near the exit.
Storing and Maintaining the Bag
A bag you packed three years ago and forgot about is only marginally better than no bag at all. Cal OES recommends reviewing your kit at least once a year, a common approach is to do it when you change your smoke alarm batteries. Check food and water expiration dates, replace any medications that have expired or whose prescriptions have changed, and make sure the power bank is charged. If you've had a life change, a new baby, a new pet, a new prescription, update the bag to reflect it.
Store the bag somewhere accessible, not in a storage unit across town or buried under boxes in the garage. A hall closet near the primary exit, or the trunk of your car if you're in a high-risk area, are common choices. The goal is to be able to grab it without thinking, even if you're woken up in the dark.
