How to Build a Home Emergency Kit (Complete Checklist)

A basic home emergency kit should include one gallon of water per person per day for at least three days, a three-day supply of non-perishable food, a first aid kit, flashlights, batteries, a battery or hand-crank radio, medications, important documents, and basic tools. FEMA and the Red Cross recommend building toward a kit that covers at least 72 hours of self-sufficiency for your household.

Building an emergency kit tends to fall to the bottom of the to-do list until you actually need one. Here’s a full breakdown to help you put one together without missing the essentials.

Quick Answer: The Core Essentials

If you only have time to gather a few things right now, focus on water, non-perishable food, a first aid kit, a flashlight with extra batteries, any regular medications, and copies of important documents. These cover the most urgent needs during the first 72 hours of most emergencies, from power outages to natural disasters.

Complete Home Emergency Kit Checklist

Water and Food

• One gallon of water per person per day, for at least three days
• Three-day supply of non-perishable food (canned goods, protein bars, dried fruit)
• Manual can opener
• Paper plates, cups, and utensils

Medical and First Aid

• First aid kit with bandages, antiseptic, and basic supplies
• Seven-day supply of prescription medications
• Over-the-counter pain relievers and any household-specific medical needs
• Hand sanitizer and disinfecting wipes

Tools and Supplies

• Flashlights (one per person) with extra batteries
• Battery-powered or hand-crank radio, ideally with a NOAA weather alert function
• Multi-tool or basic toolkit
• Duct tape and plastic sheeting
• Whistle for signaling help
• Local paper maps in case digital maps aren’t accessible

Documents and Money

• Copies of ID, insurance policies, and medical records in a waterproof container
• Cash in small bills, since ATMs and card readers may not work during power outages
• Emergency contact list, printed rather than only stored digitally

Comfort and Sanitation

• Blankets or sleeping bags
• Change of clothing per person
• Garbage bags and moist towelettes for basic sanitation
• Face masks

Detailed Guide: Storage and Rotation

Store your kit in a easily accessible location that all household members know, such as a hall closet or garage shelf, rather than somewhere hard to reach in an actual emergency. A duffel bag or large plastic storage bin works well since it’s portable if you need to evacuate.

Check food and water supplies every six months, rotating out items nearing expiration and replacing batteries in flashlights and radios. Setting a recurring reminder tied to daylight saving time changes is a common way people remember to do this consistently.

Keep a smaller version of your kit in your vehicle as well, since emergencies don’t only happen at home. A car kit typically includes a smaller water supply, snacks, a flashlight, blanket, and basic first aid supplies.

What Is a 72-Hour Kit?

A 72-hour kit, sometimes called a “go bag,” is a scaled-down emergency kit designed to sustain one person for three days if you need to evacuate quickly rather than shelter at home. It typically includes lighter, more portable versions of the same essentials in your home kit, packed into a single backpack or bag that’s ready to grab without preparation.

How Much Water Should You Store Per Person?

The standard recommendation is one gallon per person per day, covering both drinking and basic sanitation needs, for a minimum of three days. Households with pets should account for their water needs as well, and anyone in a hot climate or with medical conditions requiring more hydration may want to store additional water beyond the baseline recommendation.

Tips for Kids and Pets

For households with young children, include comfort items like a favorite small toy or book, along with any specific supplies like diapers or formula sized for at least three days. For pets, pack extra food, a collapsible water bowl, any medications, and a recent photo in case you become separated during an evacuation.

Involve older children in building the kit when possible. Walking through what’s inside and why helps reduce anxiety if the kit ever needs to be used, and makes the process feel less like a scary hypothetical and more like a practical household task.

Regional Considerations for Your Kit

Households in hurricane-prone areas should consider adding a battery bank or portable power station for charging phones during extended power outages, along with waterproof storage for important documents. Households in wildfire-prone regions may want to add N95 masks specifically rated for smoke filtration, along with a plan for quick evacuation given how fast wildfire conditions can change. Households in areas prone to winter storms should include extra blankets, hand warmers, and consider a backup heating source that doesn’t rely on electricity, along with carbon monoxide detection if using any fuel-burning backup heat source.

Checking what specific risks are common in your area, whether that’s earthquakes, flooding, tornadoes, or extended power grid failures, helps you tailor the baseline checklist to what you’re actually likely to face rather than preparing generically for every possible scenario.

Budget-Friendly Ways to Build a Kit

Building a full emergency kit doesn’t need to happen in one expensive shopping trip. Adding a few items each month, starting with water and non-perishable food, spreads the cost out and makes the project far less daunting. Many of the items on this checklist, like flashlights, batteries, and basic first aid supplies, are often available at reasonable prices during routine shopping trips rather than requiring a dedicated emergency supply purchase.

Final Thought

An emergency kit is one of those household projects that’s easy to postpone indefinitely since there’s no urgent deadline forcing action. Setting aside even one afternoon to gather the basics puts your household meaningfully ahead of where most families are, and it’s a project that, once done, mostly just needs periodic maintenance rather than starting over from scratch.

Keeping the Kit Current

An emergency kit isn’t a one-time project. Revisit it whenever your household changes, such as a new pet, a change in medication needs, or a move to a different climate, since regional risks like hurricanes, wildfires, or winter storms may call for slightly different supplies beyond the core checklist.
