How to Childproof and Petproof a New Home on Day 1
Your old home had every hazard neutralized through years of lived-in scrutiny. This one is full of unknowns: a cabinet you haven't opened, a fence gap you haven't seen, a toxic plant you haven't identified. The first 48 hours are when curious kids and newly relocated pets explore, and they find hazards adults walk past without noticing. A focused 90-minute childproofing sweep catches the worst problems before they become emergencies.

The Four-Hazard Priority List for Kids
Not every childproofing task is equal. These four categories account for the majority of serious home injuries for children under 6. Address them before anything else.
Anchor every tip-prone piece of furniture
Dressers, bookshelves, armoires, and TVs. CPSC data shows a child dies every 11 days from furniture tip-overs. Use anti-tip straps ($10 for 4-pack) attached to wall studs. Every piece taller than 30 inches needs anchoring before a child enters the home.
Latch cleaning product and medication cabinets
Under-sink cabinets in kitchen and bathrooms hold bleach, drain cleaner, dish soap, and medications. Magnetic latches (Safety 1st Magnetic Locking System, $25) install with adhesive in 10 minutes. Every under-sink cabinet plus medicine cabinet.
Cover electrical outlets at kid height
Walk every room at 2-foot height and insert tamper-resistant plugs or sliding covers. Newer homes may already have TR outlets built-in (check for TR marking)—older homes need covers. A pack of 40 plugs runs $10.
Cut or secure all window blind cords
Looped blind cords strangle approximately 9 children per year in the US. Cut looped cords in half, install cord wind-ups ($5 each), or replace with cordless blinds. No exceptions in bedrooms or playrooms.
Petproofing a New Home: Indoors and Out
Pets in a new home are more escape-prone than normal because they're disoriented. Indoor hazards include toxic plants and chemicals; outdoor hazards are primarily fence gaps and unknown plants.
- Identify every plant in the yard: Use PictureThis or PlantSnap apps. Cross-reference with the ASPCA toxic plant database. Remove or fence off lilies, sago palm, oleander, foxglove, and azalea.
- Check common indoor toxic plants: Pothos, philodendron, and lilies are frequent houseplants and highly toxic to cats. Move or remove before cats have free roam.
- Walk the fence line twice: Once outside looking under the fence, once inside checking for broken boards or loose pickets. Gaps larger than 3 inches are escape routes for cats; 4 inches for small dogs.
- Check gate hardware on every fence gate: Latches that look secure often aren't under weight. Confirm gates self-close or have a drop bolt. Install magnetic gate latches at dog height if needed.
- Inspect pool gates and fencing: Pool fences must be self-closing and self-latching with the latch at least 54 inches high. Any pool gate that swings freely is a code violation and a drowning hazard.
- Hide electrical cords and set up a safe zone: Give pets one room with bed, food, water, and litter for 24 to 48 hours while they adjust. Reduces stress and escape attempts.
The Hazards Hiding in an Unfamiliar Home
Previous owners leave behind hazards you won't find unless you look. These are the commonly missed items new homeowners discover weeks in—often the hard way.
Check for abandoned pesticides and chemicals
Look in the garage, basement, and shed. Previous owners frequently leave half-used rat poison, ant bait, weed killer, and pool chemicals. These must be removed and taken to hazmat disposal. Never consolidate into a kid-accessible area.
Inspect for loose staircase railings and trip hazards
Wobble every staircase railing. Loose rails fail when a child hangs on them. Check for loose steps, worn carpet edges on stairs, and any rug that slides on hardwood. Non-slip rug pads cost $20 and eliminate 80% of indoor slip hazards.
Check water temperature at every faucet
Previous owners may have set the water heater above 120 degrees Fahrenheit, which causes third-degree burns on a child in 5 seconds. Turn the water heater thermostat down to 120 degrees Fahrenheit today. Test a hot faucet with a thermometer after 24 hours.
Pro Tips
- •Crawl the house at kid height: Get on hands and knees in every room. You'll notice outlets, cords, sharp furniture corners, and small objects that are invisible from standing height. This one exercise reveals more hazards than any checklist.
- •Keep the ASPCA Poison Control number saved: 1-888-426-4435. Save it to every adult's phone and tape it to the fridge next to the emergency contacts list. Costs $95 per call but they handle every species.
- •Update your pet's microchip registration: The microchip database still has your old address. Update it the same week you move. A lost pet in a new neighborhood is 10x harder to recover if the chip points to the wrong city.
- •Re-do the sweep as kids age: Toddlers find hazards infants ignore. Age 2 is when outlet covers become insufficient and tamper-resistant outlets become necessary. Plan a childproofing refresh at 18 months and again at 3 years.
Frequently Asked Questions
What should I childproof first in a new home?
Prioritize the four deadliest categories: furniture anchoring (dressers, TVs, bookshelves), cleaning chemical access (under-sink cabinets with child-resistant latches), electrical outlets (tamper-resistant plugs), and window blind cords. These four alone address the majority of home injuries for children under 6 per CPSC data. Stair gates come next, followed by toilet locks, door knob covers, and stove guards. Complete furniture anchoring and under-sink latches within the first 48 hours before children have free roam.
What common houseplants are toxic to dogs and cats?
Lilies (all varieties) are severely toxic to cats and can cause fatal kidney failure from a single leaf. Sago palm is highly toxic to dogs and cats with 50% mortality if ingested. Other dangerous plants include oleander, foxglove, azalea, rhododendron, tulips, daffodils, pothos, philodendron, dieffenbachia, and castor bean. When walking a new home's yard and garden, identify every plant using apps like PictureThis or PlantSnap and cross-reference with the ASPCA toxic plants list. Remove or fence off any toxic plants before pets have outdoor access.
How do I check fencing for pet escape routes?
Walk every inch of your fence line twice—once from outside looking for gaps under the fence, and once from inside checking for broken boards, loose pickets, and gate hardware. Small dogs can squeeze through 4-inch gaps; cats through 3 inches. Pay attention to corners where fence panels meet, spots where landscaping has eroded soil beneath the fence, and gates that don't latch tightly. Temporary fixes include chicken wire along the base, landscape timbers, or L-footer dig barriers. Full repair can wait a week but gap identification cannot.
