First Home Essentials: New House Checklist for First-Time Buyers

You got the keys. The paperwork is signed, the boxes are piled in the living room, and it’s finally yours. Then it hits you: a house needs a lot more than an apartment ever did. Who knew you’d need opinions about air filters, extension cords and snow shovels?

This first home essentials checklist covers everything that comes with owning a house rather than renting one: safety gear, a real tool kit, yard tools, maintenance supplies and the moving-day box that saves your sanity. We’ve skipped the generic stuff and focused on what new homeowners actually need in the first few weeks, plus what can wait until you’ve lived there a while.

Before You Move In: Your First-Week To-Do List

A little prep before the furniture arrives makes everything easier (and safer). Most of this costs nothing:

• Change or rekey the locks. You have no idea how many copies of the old keys are out there.
• Find the main water shutoff and the breaker panel. Label the breakers now, not during a leak at 2 a.m.
• Test every smoke and carbon monoxide alarm. Replace any that don’t work or are past their date.
• Check the HVAC filter. Write the size down, because you’ll be buying these for years.
• Deep clean while the rooms are empty. It’s ten times easier before the couch moves in.
• Set up utilities, internet and trash pickup so day one isn’t spent on hold.

Moving from an apartment? Your kitchen, bathroom and bedroom basics are covered in our first apartment checklist, so this list focuses on everything a house adds.

Safety First

Start here before anything else. These are the items that protect your family and your biggest investment.

• Smoke and carbon monoxide alarms: One on every level, inside each bedroom and outside sleeping areas. The NFPA recommends replacing smoke alarms every 10 years, so check the date on any you inherit. If your house has hardwired alarms, replace them with hardwired ones (an electrician can help).
• Fire extinguishers: Keep one in the kitchen and one in the garage, and make sure everyone knows where they are.
• New locks: A keypad deadbolt means no more hiding spare keys under the mat.
• A video doorbell: See who’s at the door (and catch package thieves) from your phone.
• A first aid kit: Bigger than the one you had in your apartment. Houses come with more projects and more scraped knuckles.
• Water leak detectors: Cheap little sensors under sinks and near the water heater that can save you from a very expensive surprise.

Smoke & Carbon Monoxide Detector Best Pick

Home Fire Extinguisher Best Pick (2-pack!)

Keypad Deadbolt Best Pick (no more hidden spare keys!)

Video Doorbell Best Value Pick

Home First Aid Kit Best Pick (family-size!)

Water Leak Detectors Best Pick (multi-pack!)

Your Starter Tool Kit

In an apartment, you called the landlord. Now you’re the landlord. A small, solid tool kit handles 90% of new-house jobs: hanging curtains, tightening hinges, assembling furniture and unclogging the drain your house had waiting for you.

• A cordless drill: The one tool every homeowner uses weekly. Get a kit with a battery and charger.
• An all-in-one tool set: Hammer, screwdrivers, pliers, wrenches, tape measure and a level in one case.
• A sturdy step ladder: For light bulbs, smoke alarms and high shelves. Please don’t use a chair.
• A stud finder: So the heavy mirror and the TV stay on the wall.
• A drain snake: For sink, tub and shower clogs a plunger can’t touch. (Toilets need a toilet auger, a different tool.)
• A wet/dry shop vac: Garage messes, water spills, drywall dust. It does what a regular vacuum can’t.

Cordless Drill Kit Best Pick (with battery and charger!)

Homeowner Tool Set Best Pick (all-in-one with case!)

Step Ladder Best Pick (sturdy and foldable!)

Stud Finder Best Pick

Drain Snake Best Pick (for sink and tub clogs!)

Wet/Dry Shop Vacuum Best Pick

Maintenance Must-Haves

These are the boring purchases that keep a house running smoothly (and keep small problems from becoming big ones).

• HVAC air filters: Most need changing every 1 to 3 months. Buying a multi-pack in your size means you’ll actually do it.
• LED light bulbs: Houses have a lot of sockets, and half the bulbs will be burned out or mismatched. A bulk pack fixes that in one afternoon.
• A rechargeable lantern or flashlight: For power outages and trips to the basement.
• A heavy-duty outdoor extension cord: For yard tools, holiday lights and that one outlet that’s always too far away. Plug it into a GFCI outlet and never daisy-chain cords together.

Rechargeable Lantern Best Pick (for power outages!)

HVAC Air Filters Best Value Pick (multi-pack!)

LED Light Bulbs Best Value Pick (bulk pack!)

Outdoor Extension Cord Best Pick (heavy-duty!)

Lawn and Yard

If your new house has a yard, congratulations, you now have a weekend hobby. Battery-powered tools are the easiest place to start: no gas, no pull cords, and you can share batteries between them if you stick to one brand.

• A lawn mower: A cordless electric mower handles most suburban lawns quietly.
• A string trimmer and leaf blower: For the edges and the cleanup that make a yard look finished.
• A garden hose (plus a spray nozzle): For plants, cars, patios and kids on hot days.
• A rake: Fall arrives every year, whether you’re ready or not.
• A snow shovel: If you live anywhere that snows, buy it before the first storm (they sell out).
• A heavy-duty doormat: Your floors will thank you.

Cordless Lawn Mower Best Pick (battery-powered!)

Cordless String Trimmer Best Pick

Cordless Leaf Blower Best Pick

Garden Hose Best Pick (kink-resistant!)

Leaf Rake Best Pick (adjustable!)

Snow Shovel Best Pick (back-friendly!)

Outdoor Doormat Best Pick (all-weather!)

Garage and Storage

The garage becomes the “deal with it later” room within a week. Shelving and clear bins keep it usable (and keep the car inside). Anchor tall shelving units to the wall so a loaded shelf can’t tip over.

Garage Shelving Unit Best Pick (heavy-duty!)

Clear Stackable Storage Bins Best Value Pick

Cleaning a Whole House

More rooms, more stairs, more floors. A cordless vacuum with a long runtime saves you from dragging a cord up and down the stairs, and a spin mop makes hard floors a quick job.

• A cordless vacuum with enough battery for the whole house.
• A spin mop and bucket for hard floors. (Empty the bucket after every use if you have little ones at home.)
• An extendable duster for ceiling fans and high corners you didn’t have in your apartment.

Cordless Vacuum for the Whole House Best Pick

Spin Mop and Bucket Best Pick

Extendable Duster Best Pick (for ceiling fans and high corners!)

Moving Day Essentials: Pack a First Night Box

The day you move in, you’ll be exhausted and surrounded by boxes, and the one thing you need will be in the box at the very bottom. Pack one box (or a suitcase) with the essentials, label it “First Night,” and keep it in your car:

• Toilet paper, hand soap and a roll of paper towels
• Phone chargers, a power strip and a flashlight
• Sheets, pillows and towels for everyone
• Basic tools for putting beds together
• A mini kitchen kit: a pan, a knife, plates, mugs and a can opener
• Medications, toiletries, snacks and a change of clothes
• Trash bags (you’ll fill more than you think)

If you’re still packing up the old place, a moving box kit with tape saves you from hunting down boxes behind the grocery store. One kit usually covers about a bedroom’s worth of stuff, so plan on two or three for a whole house.

Moving Boxes Kit Best Value Pick (about one room per kit!)

Nice-to-Haves: Upgrades for Later

You don’t need these on day one, but they’re worth adding once the boxes are unpacked:

• A smart thermostat: Saves money on heating and cooling, especially if the house came with an old manual one. Check compatibility with your system first (most don’t work with line-voltage baseboard heat), and turn off the breaker before installing.
• Ceiling fans in bedrooms that don’t have them.
• A water filter for the kitchen sink or fridge.
• Patio furniture and a grill for the backyard you finally have.
• Window treatments for every room, once you know which rooms get morning sun.

Smart Thermostat Best Pick

How to Budget for Your First Home Essentials

Buying a house is expensive, and the closing costs have a way of draining the “fun money.” Here’s how to keep the essentials list from getting out of hand:

• Safety first, always. Alarms, extinguishers and locks before anything decorative.
• Pick one battery brand for cordless tools. Batteries are the expensive part, and sharing one battery across your mower, trimmer and blower (like the EGO picks above) saves a lot.
• Borrow before you buy big, rarely used tools from neighbors or a tool library.
• Watch the holiday sales. Tools and yard gear go on sale around Father’s Day, Black Friday and spring.

The first few months in a new house are a learning curve, and that’s normal. Get the safety gear and basic tools in place, keep the first night box handy, and add the rest as you discover what your house actually needs.

Frequently Asked Questions

Should I change the locks when I buy a house? Yes, ideally on day one. Previous owners, their relatives, contractors and real estate agents may all still have keys. Rekeying the existing locks is usually cheaper than replacing them, or you can switch to a keypad deadbolt like our pick above and skip keys altogether.

What should I buy first for a new house? Safety items first: smoke and carbon monoxide alarms, fire extinguishers and new locks. Then a drill and tool kit, followed by cleaning supplies and the yard tools you’ll need for the season you move in.

Do new houses come with smoke detectors? Usually, but don’t assume they work. Test every alarm on move-in day and check the manufacture date on the back. Smoke alarms should be replaced every 10 years, and carbon monoxide alarms typically every 5 to 7 years depending on the model.

What tools does a new homeowner need? A cordless drill, an all-in-one tool set (hammer, screwdrivers, pliers, wrenches, tape measure, level), a step ladder, a stud finder, a plunger and a drain snake. Add a shop vac and yard tools as you need them.

How much should I budget for first home essentials? It depends on the size of the house and the yard, but many first-time buyers spend a few thousand dollars in the first year on tools, yard equipment and household basics. Spread purchases out and prioritize safety and maintenance items first.
