Your New Home Checklist: The Top 10 Safety Items Every New Homeowner Needs to Address Right Now

Moving into a new home is one of the most exciting experiences in life. There are boxes to unpack, rooms to decorate, and neighbors to meet. Safety inspections and system checks are probably the last thing on your mind. But the first weeks in a new home — whether it's brand new or decades old — are exactly the right time to address the safety items that protect your family, your investment, and your peace of mind. Some of these take five minutes. Some take an afternoon. All of them matter.

At White Glove Building Inspections, we have spent over 35 years helping Chicagoland homebuyers understand exactly what they are moving into. This list reflects what we see in homes every single day — the safety items that are most frequently overlooked, most commonly deficient, and most important to get right from day one.

1. Rekey Every Lock in the Home — Immediately

This is the first thing every new homeowner should do — before the moving truck is unloaded. You have no way of knowing how many copies of your home's keys exist. Previous owners may have given keys to neighbors, house cleaners, contractors, family members, or friends, real estate agents, past tenants, and even prior owners before the people you bought from may have copies. Rekeying locks or replacing them entirely with new hardware — is inexpensive, takes less than an hour with a locksmith, and immediately closes a security vulnerability that most new homeowners don't think about until something goes wrong. While you're at it, check that all ground-floor windows have functioning locks, and consider adding secondary security pins or window stops to any windows that could be accessed from outside.  Don’t forget that Ringbell, cameras, and security systems, if present, need attention. 

2. Test Every Smoke Detector and Replace Batteries

Smoke detectors save lives — but only when they work. The U.S. Fire Administration recommends smoke detectors on every level of the home, inside every bedroom, and outside every sleeping area. Test every detector in the home the day you move in by pressing and holding the test button. Replace the batteries in every unit regardless of how new they appear — you don't know when they were last changed. If any detector is more than 10 years old (check the manufacturing date printed inside the cover), replace it entirely. Smoke detector sensors degrade over time and become less sensitive, even with fresh batteries. While you are evaluating detectors, make a note of where they are located and confirm that the coverage meets current recommendations for your home's layout.

3. Install Carbon Monoxide Detectors on Every Level

Carbon monoxide is odorless, colorless, and deadly. It is produced by malfunctioning or improperly vented combustion appliances — furnaces, boilers, water heaters, gas ranges, fireplaces, and vehicles in the attached garage. Carbon monoxide poisoning kills hundreds of Americans every year and sends tens of thousands more to emergency rooms. Illinois law requires carbon monoxide detectors in all residential dwellings, and they should be installed on every level of the home, particularly near sleeping areas. If your new home has combination smoke and CO detectors, confirm they are within their service life. If it has separate CO detectors, test them and check the manufacturing date. Carbon monoxide detectors have a service life of five to seven years regardless of battery condition — replace any unit that has exceeded that age.

4. Locate the Main Water Shutoff and Test It

A burst pipe, a failed supply line, or a plumbing emergency can dump hundreds of gallons of water into your home in minutes. Knowing where your main water shutoff valve is located — and confirming that it actually works — is essential knowledge for every homeowner. In most homes, the main shutoff is located where the water supply enters the home: in the basement near the front foundation wall, in a utility room, or in a crawl space. Once you locate it, turn it off and back on to confirm it operates smoothly. Valves that have not been exercised in years can seize or fail to fully close when you need them most. If the valve is stiff, corroded, or leaking, have a plumber service or replace it before an emergency forces you to use it.

5. Locate the Electrical Panel and Label Every Breaker

Find your electrical panel and open it up. Many homes have panels with breakers that are unlabeled, mislabeled, or labeled in ways that made sense to a previous owner but mean nothing to you. Spend an hour with a helper — one person at the panel, one walking the home — systematically tripping each breaker and identifying what it controls. Label every breaker clearly. This simple exercise accomplishes two important things: it gives you an accurate map of your electrical system for future use, and it gives you the chance to identify any obvious panel issues — double-tapped breakers, breakers that feel warm, breakers that won't reset — that should be evaluated by a licensed electrician. If your home has a Federal Pacific, Zinsco, or Challenger panel (see our blog on dangerous electrical panels), consult an electrician about replacement immediately.

6. Have Furnace and HVAC System Serviced

Schedule a professional HVAC service call within the first season of moving into your new home — ideally before you first need to use the heating or cooling system heavily. A qualified technician will clean the system, check combustion efficiency, inspect the heat exchanger for cracks that could allow carbon monoxide to enter the living space, verify that flue connections are intact and properly venting, and change the air filter. You have no way of knowing the service history of the HVAC system in a home you just purchased. An aging furnace with a cracked heat exchanger is a carbon monoxide hazard that can be present with no visible warning signs whatsoever. A $150 service call that catches a cracked heat exchanger is one of the best investments a new homeowner can make.

7. Test All GFCI Outlets and Install Where Missing

Ground fault circuit interrupter outlets — the outlets with the TEST and RESET buttons — are required by code in kitchens, bathrooms, garages, exterior locations, and anywhere else that an outlet is near a water source. They are designed to cut power in a fraction of a second when they detect a ground fault, preventing electrocution. Test every GFCI outlet in your home by pressing the TEST button and confirming that it trips, then press RESET to restore power. If any GFCI outlet fails to trip or fails to reset, replace it immediately. If you find standard outlets in locations where GFCI protection is required, have a licensed electrician add GFCI protection — either with a GFCI outlet or a GFCI breaker — before those locations are used. This is one of the most common electrical deficiencies found in home inspections, including in homes that have passed local code inspections.

8. Check Water Heater Temperature and Pressure Relief Valve

Your water heater presents two safety concerns that are quick to address but important not to ignore. First, check the temperature setting. The recommended setting is 120 degrees Fahrenheit — hot enough to prevent Legionella bacterial growth, but below the scalding threshold for adults and children. Many water heaters are set higher than necessary, increasing scalding risk and energy consumption. Second, locate the temperature and pressure relief valve — the T&P valve — on the side of the water heater. This safety device opens automatically if temperature or pressure inside the tank exceeds safe limits, preventing catastrophic tank failure. Confirm that the valve has a discharge pipe directing it downward, away from the burner and toward the floor or a drain. If the T&P valve shows signs of leaking, corrosion, or previous discharge, have a plumber replace it. A failed T&P valve on an overheated water heater is a serious hazard.

9. Test Radon Levels — Especially in the Chicagoland Area

Radon is a naturally occurring radioactive gas that seeps from the soil into homes through foundation cracks, sump pits, and utility penetrations. It is the second leading cause of lung cancer in the United States, responsible for approximately 21,000 deaths per year — and it is completely undetectable without testing. The Chicagoland area, including Naperville and the surrounding communities, falls within EPA Zone 1 and Zone 2 for radon — regions with elevated radon potential where testing is strongly recommended for every home. If a radon test was not performed as part of your home inspection, purchase a short-term radon test kit from a home improvement store or contact a certified radon testing professional. If your results come back at or above 4 picocuries per liter (pCi/L), contact a licensed radon mitigation contractor. Radon mitigation systems are highly effective, typically reducing levels by 90 percent or more, and cost $800 to $2,500 for most residential installations.

10. Purchase and Place a Fire Extinguisher on Every Level

Every home should have at least one readily accessible fire extinguisher, and ideally one on every level — with a dedicated unit in the kitchen and where the clothes dryer is located, where the majority of residential fires start. Choose a multi-purpose dry chemical extinguisher rated ABC, which covers ordinary combustibles, flammable liquids, and electrical fires. Mount it in a visible, accessible location — not buried in a cabinet where you'll spend precious seconds looking for it in an emergency. Learn how to use it before you need to: the PASS method — Pull the pin, Aim at the base of the fire, Squeeze the handle, Sweep side to side — is straightforward but worth practicing. Check the pressure gauge annually and replace or recharge the extinguisher if the gauge needle drops out of the green zone or after any use, even partial and if past the expiration date.

One More: Create a Home Safety Binder

Before the chaos of moving in takes over, take an afternoon to create a home safety binder — a single organized location for your inspection report, appliance manuals and warranty documents, HVAC service records, the location of every shutoff valve and the electrical panel map you created, and emergency contact numbers for your plumber, electrician, and HVAC technician. When a pipe bursts at 11 PM on a January night or a circuit breaker won't reset before a holiday gathering, having this information immediately at hand is invaluable. New homeowners who do this in the first week almost always say it was one of the smartest things they did.
