How to Childproof and Pet-Proof a New Home

Within a day of moving in, your toddler will find the one cabinet you forgot to latch, and your dog will discover a gap behind the dryer you never knew existed. A house you’ve lived in for years has been quietly edited for safety over time. A new one hasn’t. Every outlet, stairwell, balcony rail, and shrub in the yard is an unknown until you check it, and the people and animals who trust you to keep them safe don’t yet know where the hazards are either.

This guide walks you through hazard-proofing a new home room by room for kids and pets. It focuses on the physical safety setup of an unfamiliar space. It does not cover the structural and systems inspection you do before moving in (see our guide on what to inspect before move-in), changing your entry-door locks for security, or the emotional side of helping children and pets adjust. Those are separate jobs. Here, the question is narrower and more urgent: before small hands and curious noses have the run of the place, what could hurt them, and how do you shut those risks down first?

Why a New Home Needs a Fresh Safety Sweep

The danger of a new house is precisely that it’s new to you. You don’t yet know which steps creak and shift, whether the deck railing has wide gaps, how hot the tap runs, or what the previous owner left under the kitchen sink. Familiarity is a safety system you haven’t built yet.

Move-in week stacks the odds against you, too. Doors prop open for hours while the truck unloads. Boxes block sightlines. Cleaning supplies, tools, and medications get set down “just for now” on low surfaces. A child or pet that’s already unsettled by the chaos is more likely to wander, climb, and chew. The same week you have the least attention to spare is the week the house is least secure.

The fix is to treat childproofing and pet-proofing as part of unpacking, not a project for later. Do a deliberate pass before kids and pets are loose in the home, then keep a closer eye on them for the first several days while you learn the space. Get down to their eye level in each room. What looks reachable, swallowable, or climbable from eighteen inches off the floor is not what you notice standing up.

Securing Furniture, Cords, and Windows From Tip-Overs and Falls

Furniture and television tip-overs are one of the most serious home hazards for young children, and a move is exactly when they happen. Dressers, bookcases, and TVs get set in place before they’re anchored, and a child climbing an unsecured dresser like a ladder can pull it over. The U.S. Consumer Product Safety Commission’s national “Anchor It!” campaign urges anchoring TVs and top-heavy furniture such as bookcases and dressers securely to the wall. Anti-tip brackets are inexpensive, and CPSC notes most anti-tip kits cost under $20 and install in under 20 minutes. Anchor into wall studs, not just drywall, and do it as each piece lands rather than adding it to a someday list. Push heavy items low and toward walls, and don’t store tempting objects like toys or remotes on top of furniture a child might climb to reach.

Window covering cords are a quieter but lethal hazard. The CPSC reports that, on average, about nine children under five die each year from strangling in window blind, shade, or drapery cords, and entanglement can cause strangulation in under a minute. The agency’s clear guidance is that cordless window coverings are the only option that eliminates the strangulation risk, so where young children are present, install cordless products in every room they’ll use. If you can’t replace existing corded coverings right away, CPSC advises keeping cords short and out of reach, installing and adjusting cord stops, anchoring continuous-loop cords to the wall or floor, and moving cribs, beds, and furniture away from windows and cords.

Windows themselves are a fall risk, especially above the ground floor. A screen keeps bugs out but will not stop a child who leans against it. Keep furniture a child could climb away from windows, and look into window guards or stops that limit how far a window opens.

Kitchens, Bathrooms, and Cabinets: Locks and Latches

The kitchen and bathrooms concentrate the most poisons and burn risks in the house, and in a new home you may not yet know what’s stored where. Before kids or pets explore, open every low cabinet and drawer. The American Academy of Pediatrics’ HealthyChildren.org recommends safety latches or locks on drawers and cupboards, and storing all medicines and supplements in their original packaging in locked cabinets. The cabinet under the sink, where cleaners and dishwasher pods usually live, is a top priority. Relocate anything toxic up high and out of reach, then latch what remains.

Hot tap water is an underrated danger to small children. The CPSC urges setting water heaters to 120 degrees Fahrenheit. The agency notes that at 140 degrees a serious burn can occur in about six seconds, while a lower setting buys critical time. After move-in, locate the water heater and check the dial, since you have no idea where the last occupant left it (for help finding your water heater and other systems, see our guide on locating shutoffs and breakers). Anti-scald devices on faucets and showerheads add another layer.

In the bathroom, latch the cabinet that holds medications, razors, and cleaners, and never leave a young child alone near standing water. A few inches in a tub or even a mop bucket is enough to be dangerous, and a curious pet can be drawn to an open toilet. Keep toilet lids down and bathroom doors closed when the room isn’t in use.

Stairs, Outlets, and Door/Gate Barriers

Stairs are one of the first features a crawling or newly walking child will test, and a new staircase may be steeper, more open, or differently lit than what they’re used to. HealthyChildren.org recommends installing safety gates at both the top and bottom of stairs, mounting them firmly to wall studs, and avoiding old accordion-style gates that can trap a child’s arm or neck. Hardware-mounted gates are the sturdier choice for the top of stairs.

Electrical outlets sit right at toddler height. The AAP advises putting safety covers in all unused outlets to keep a child from inserting a finger or object, and blocking stubborn outlets with furniture if a child won’t leave them alone. Choose covers large enough that they aren’t themselves a choking hazard. Walk the new house and count the outlets, because there are usually more than you expect, and a move often means lamps and chargers plugged in at floor level with cords trailing.

Doors and gates control where kids and pets can go. HealthyChildren.org suggests using gates, door locks, or doorknob covers to keep a toddler from slipping outside or into the garage unnoticed. In a new home the garage, basement, and yard are full of unknowns, so keep those doors secured until you’ve cleared each space. During move-in, when the front door is open and people are coming and going, a baby gate or a watchful adult at the threshold prevents a fast exit toward the street.

Pet-Specific Hazards (toxic plants, gaps, fencing, secure spaces)

Pets face their own version of the unfamiliar-house problem, and some of their hazards are invisible to a person scanning at standing height. Plants are a big one. The ASPCA warns that many common houseplants and landscaping plants are toxic to pets, including lilies, sago palms, tulips, and azaleas. Lilies are especially dangerous to cats, where even small exposures, including pollen, can cause kidney failure. Inventory both the plants you’re bringing and anything growing in the new yard or left behind by the previous owner, and remove or fence off what you can’t identify as safe.

The garage and utility areas deserve a careful sweep before a pet is loose. The ASPCA highlights antifreeze as a serious threat: it commonly contains ethylene glycol, which is highly toxic, tastes sweet to animals, and can be fatal in a small amount. Store antifreeze, pesticides, and rodenticides sealed and high up, and check the new garage and shed for spills or bait stations the last occupant may have left. The ASPCA also notes that ingesting concentrated cleaners like undiluted bleach can injure a pet’s mouth and esophagus, so keep cleaning products secured the same way you would for a child.

Then there are the gaps. A new house has openings your pet will find before you do: a loose deck board, a gap behind appliances, a fence with a missing slat, a gate that doesn’t latch flush. Walk the yard fence line looking for holes, weak spots, and gaps under the fence a determined dog could dig through. Indoors, block access behind the refrigerator, washer, and dryer where a cat might wedge in. Set up one quiet, secured space, such as a closed room or crate with water and a familiar item, where a stressed pet can stay during the busiest hours of move-in without bolting through an open door. Keep your pet’s ID current as a backstop in case they do get out (see our guide on updating pet records and microchip info).

A Quick Walk-Through Safety Check Before Kids and Pets Move In

Before you let kids and pets roam, do one focused walk-through, ideally crouched to their height. Move through the house room by room and confirm each item:

Furniture and TVs: dressers, bookcases, and televisions anchored to studs; nothing tempting stored on top.
Windows: cordless coverings or cords secured out of reach; climbable furniture moved away from windows; guards or stops where there’s a drop.
Kitchen and bathrooms: cleaners, medications, and sharp items moved up high and latched; water heater confirmed at 120°F; toilet lids down.
Stairs and outlets: hardware-mounted gates at the top and bottom of stairs; covers in unused outlets; trailing cords tucked away.
Doors and exits: garage, basement, and exterior doors secured; a gate or adult at the door during move-in.
Pet hazards: toxic plants removed or fenced off; antifreeze, pesticides, and rodenticides sealed and high; fence line and gaps checked; one quiet, secured space ready.
Floors and small objects: packing materials, plastic bags, zip ties, screws, and coins picked up from the floor, since these are choke and swallow hazards everywhere during a move.

Keep two phone numbers handy as you settle in. For a child, the national Poison Help line is 1-800-222-1222, free and confidential, 24 hours a day. For a pet, the ASPCA Animal Poison Control Center is (888) 426-4435, also available around the clock, though a consultation fee may apply. Save both in your phone and post them on the fridge before you need them.

A new home rewards patience. You won’t catch everything on day one, and you’ll keep adjusting as you learn the space and as kids grow into new abilities. The goal of the first sweep isn’t perfection. It’s making sure the obvious, serious hazards are handled before anyone you love starts exploring a house none of you knows yet.
