Most home safety comes down to a short list of inexpensive devices and protections — and to checking that they actually work. Here are the ten things every home should have, why each matters, and how to confirm yours is doing its job. Many of these are exactly what a home inspector looks for, because they’re the difference between a near-miss and a tragedy.
1. Working smoke alarms (in the right places)
You need alarms inside every bedroom, outside each sleeping area, and on every level of the home. Test them monthly, replace batteries yearly (or use 10-year sealed units), and replace the alarms themselves every 10 years — they wear out. Interconnected alarms, where one triggers them all, are best.
2. Carbon monoxide (CO) detectors
CO is an odorless, deadly gas produced by any fuel-burning appliance — a gas range, water heater, furnace, or a car in an attached garage. Put CO detectors near sleeping areas and on each level, especially if you have any gas appliances. They’re cheap insurance against an invisible threat.
3. Fire extinguishers
Keep at least one multi-purpose (ABC) extinguisher in the kitchen and the garage, mounted and accessible. Check the gauge periodically and know the “PASS” technique — Pull, Aim, Squeeze, Sweep — before you ever need it.
4. GFCI protection near water
Ground-Fault Circuit Interrupters cut power in a fraction of a second if they sense a fault — preventing electrocution. They’re required at outlets near water: kitchens, bathrooms, laundry, garage, and outdoors. Test them with the built-in button; a GFCI that won’t trip needs replacement.
5. AFCI protection against arc faults
Arc-Fault Circuit Interrupters detect the dangerous electrical arcing that causes many house fires, and shut the circuit down. Modern homes have them on most living-area circuits; older homes often don’t, which is worth knowing.
6. A safe electrical panel
Your panel should be free of double-tapped breakers, missing covers, corrosion, and known-hazard brands. You don’t need to open it yourself — but it’s a top focus of any inspection, because panel defects create both shock and fire risk.
7. Water-heater safety: TPR valve + drain pan
As covered in our water heater guide, every tank needs a temperature-and-pressure relief (TPR) valve with a proper discharge tube, and a drain pan wherever a leak could cause damage. A missing TPR tube is a genuine safety hazard, not just a code item.
8. Handrails and guardrails
Handrails on stairs and guardrails on balconies, decks, and elevated landings prevent falls — the most common home injury. Guardrails should be sturdy, the right height, and have baluster spacing tight enough that a child can’t slip through (a 4-inch rule of thumb).
9. Secured, properly vented gas appliances
If you have gas, appliances need proper venting and accessible shutoff valves, and a freestanding range needs an anti-tip bracket so it can’t tip forward. Gas safety overlaps with your CO detectors above — together they protect against the two big gas risks: leaks and combustion byproducts.
10. Knowing your shutoffs and an escape plan
Finally, the knowledge items: every adult in the home should know where the water, electrical, and gas shutoffs are and how to use them, and the household should have a fire escape plan with two ways out of every room and a meeting point. In Florida, that readiness ties directly into hurricane preparation.
How these work together
Safety isn’t any single device — it’s the layers. Alarms warn you, GFCIs and AFCIs prevent the event, extinguishers and shutoffs let you respond, and rails and brackets stop the everyday accidents. Gaps in any layer are what turn small incidents into emergencies.
Why an annual look matters
A home inspection systematically checks every item on this list — alarm placement, GFCI/AFCI function, the panel, the water heater’s safety valve, rails and spacing, gas shutoffs and venting — and Prosight’s included thermal imaging adds a look for overheating electrical connections that can’t be seen any other way. It’s the most thorough way to know your home is genuinely safe. Make it a yearly habit alongside the other reasons annual inspections pay for themselves, and schedule an inspection when you’re ready.
