Build the household baseline
Ready.gov frames a basic kit around being self-sufficient for several days. For a home, that means water, food, light, first aid, sanitation, communication, documents, medication, pet needs, and weather-specific comfort. Start with 72 hours because the gaps are easy to see, then extend water, food, batteries, hygiene, and medication in weekly layers.
Home preparedness checklist
- Water: one gallon per person per day as a planning baseline, plus pet water, hygiene water, and a treatment method.
- Food: several days of familiar shelf-stable meals, manual can opener, safe cooking plan, and food safety thermometers.
- Power and light: flashlights, headlamps, lanterns, spare batteries, charged power banks, and a radio with battery or hand-crank backup.
- Health: first aid kit, prescriptions, nonprescription medicine, glasses, copies of medical information, and hygiene supplies.
- Sanitation: soap, sanitizer, wipes, trash bags, gloves, disinfectant, toilet backup, and paper goods.
- Documents: IDs, insurance, bank records, titles, prescriptions, pet records, contact cards, and some cash in a waterproof container.
Power, heat, and cooling
Use battery lighting before candles. Keep refrigerator and freezer doors closed during outages and track time so food decisions are based on safety, not hope. Never run generators, grills, camp stoves, or charcoal indoors or in garages. In cold weather, close unused rooms, block drafts, layer clothing, and gather sleeping areas. In extreme heat, plan shade, airflow, hydration, and a backup location if the home becomes unsafe.
Extend beyond 72 hours
Modern outages increasingly last longer than three days. Many emergency managers now recommend a seven-day baseline for water and food, because infrastructure repair timelines and supply chain disruptions can extend well past the weekend. After you have 72 hours covered, add one extra day per week until you reach seven, then re-assess based on your household's specific medical and mobility needs.
Medications, medical equipment, and special needs
Prescription management is one of the most under-prepared areas in household readiness. Aim for a 30-day buffer by requesting early refills when possible, and document every medication with name, dose, prescribing doctor, and pharmacy contact in a waterproof card. Households with power-dependent medical equipment — oxygen concentrators, CPAP, insulin storage, home dialysis — need a written utility-failure plan coordinated with the equipment provider and local utility company before an emergency happens. Note any household member's allergies, hearing or vision limitations, and mobility needs in your document kit.
Air quality and chemical hazards
Wildfire smoke, industrial accidents, and chemical releases are increasingly common reasons to shelter in place with sealed windows. Keep a small supply of N95 respirators for each household member. During a smoke event, close all windows and doors, switch HVAC to recirculate, and avoid cooking or anything that raises indoor particulates. Authorities issue shelter-in-place instructions for specific airborne hazards; follow local guidance on whether to seal a room rather than doing it preemptively, as improper sealing can reduce breathable air. A battery-powered carbon monoxide detector is non-negotiable in any home that may use combustion devices during an outage.
Household dependency map
List what your household depends on each day: electricity, refrigeration, water pressure, internet, transportation, prescription access, mobility equipment, pet care, childcare, and heating or cooling. Then write what fails when each dependency stops. A freezer outage creates food decisions. A water outage creates toilet and hygiene decisions. A medication dependency creates timing and storage decisions. A mobility dependency changes evacuation planning and shelter choices.
This map keeps home preparedness practical. Instead of buying random gear, you can solve the most fragile dependencies first. If someone needs powered medical equipment, battery backup and a utility notification plan come before camp gadgets. If the home has a well pump, stored water moves up the list. If summer heat is the main threat, cooling and hydration matter more than winter blankets.
Priority reset questions
Use this guide as a seasonal reset rather than a one-time read. Ask what changed since the last review: new address, new commute, new school, new medication, new pet, new vehicle, new weather risk, or new family responsibility. Preparedness plans drift out of date quietly. A short review keeps the system matched to the life you actually have now.
Then choose one action that can be finished today. Replace expired supplies, print a contact card, charge a battery, label a container, test one tool, or move gear to the place where it will be needed. Small completed actions beat large plans that stay theoretical.
Document the result of each reset in one sentence: what changed, what was replaced, and what still needs attention. That tiny note makes the next review faster and helps another household member understand the system without asking where everything is or why it was packed that way.
Make one household member responsible for the next review date and write that date directly on the container, printed checklist, or calendar. Ownership prevents the supplies from becoming anonymous clutter and makes the system easier to maintain when the household is busy.
Common mistakes
- Buying gear before writing down household needs, medication requirements, and local hazards.
- Storing everything in one place that may be blocked by fire, flood, or a damaged garage door.
- Forgetting sanitation, pet supplies, spare glasses, and paper copies of contacts.
- Letting batteries, water, food, and prescriptions expire quietly.
Maintenance rhythm
Use a seasonal review. Replace expired medicine and food, recharge power banks, test flashlights and radios, refresh water, check smoke and carbon monoxide alarms, and update documents after moves, new jobs, new schools, new pets, or health changes. Once a year, run a no-power evening so the household learns where lights, radios, and comfort items are stored.
Scenario notes
For winter storms, prioritize heat retention, safe cooking, water, and prescription access. For summer outages, prioritize food safety, cooling, hydration, and neighbors who may be medically vulnerable. For chemical emergencies, be ready to follow local shelter-in-place instructions and seal a room only when directed by authorities.
