The keys are finally in your hand, the truck is in the driveway, and a wall of boxes is waiting. It’s an exciting moment — and a slightly overwhelming one. When everything feels urgent, it helps to know which tasks genuinely come first and which can wait until the weekend.
This guide walks through the first things to do when moving into a new house, roughly in the order that matters most: safety and security, then the systems that keep the house running, then the practical setup that turns a new address into home. You don’t have to do it all on day one. But knowing where to start makes the whole move feel far more manageable.
Start with safety and security
Before you think about where the couch goes, spend your first hour making the house safe. These tasks are quick, and they protect the people and belongings you just moved in.
Change or rekey the locks
You have no way of knowing how many copies of the old keys are floating around — former owners, contractors, cleaners, neighbors, a real estate agent. Changing or rekeying every exterior lock is the single most important thing to do on move-in day. Don’t forget the side door, the garage entry, and any basement or patio doors.
You have two options: rekey the existing hardware (a locksmith adjusts the lock so old keys no longer work) or replace the locks entirely. Rekeying is usually faster and cheaper if the hardware is in good shape; replacing makes sense if you want new finishes or smart locks. For a deeper walkthrough of rekeying versus replacing and every code and device worth resetting, see our guide on when to change the locks after buying a house.
Test smoke and carbon monoxide detectors
Press the test button on every smoke and carbon monoxide detector in the house. Swap in fresh batteries, and if any unit looks yellowed or is more than about ten years old, replace it. It’s a five-minute job that’s easy to skip in the chaos of moving — and one you’ll be glad you didn’t.
Locate the main water shutoff and electrical panel
Find these before you need them in an emergency. The main water shutoff valve is usually where the water line enters the house — in a basement or crawl space, a utility closet, near the water heater, or in warmer climates like much of Texas, near an outdoor faucet or in a covered box near the street. Look for a lever or a round wheel and make sure you can turn it.
While you’re at it, find the electrical panel and check that the breakers are labeled. If they aren’t, labeling them is a great rainy-day project. Knowing how to cut the water or flip a breaker fast can turn a burst pipe or electrical scare into a minor inconvenience instead of a disaster.
Confirm the systems that keep the house running
With the house secure, turn to the services and systems you’ll rely on every day. Ideally you arranged these before the move, but move-in day is the time to confirm they actually work.
Make sure the utilities are on and in your name
Walk the house and check that electricity, water, and gas are all live. Flip switches, run a faucet, and confirm the water heater and HVAC respond. Then verify each account is in your name and billed to your new address so you’re not paying for someone else’s usage — or facing a surprise shutoff. If anything isn’t on yet, call the provider right away.
If you haven’t set everything up, or you’re still sorting out who to call for what, our overview of setting up utilities breaks down the order to tackle electricity, water, gas, and trash so nothing slips through. In parts of Texas with a deregulated electricity market, you also get to choose your own provider — worth doing before your first bill rather than after.
Check internet and connectivity
For many households, getting online is nearly as essential as the water being on. If your installation isn’t scheduled yet, book it early — appointment windows fill up, especially at the end of the month when a lot of people move. Our timeline for internet and TV setup can help you plan so you’re connected on day one instead of a week in.
Set up or review your home security
If the home has an existing alarm system, change the codes and, where possible, transfer or restart monitoring under your account. If it doesn’t, moving in is the natural moment to decide what level of security fits your needs — from a simple video doorbell to a fuller system. Our home security resource covers the options so you can protect a house that’s still half full of boxes.
Get the house livable
Now for the part that actually feels like moving in. A little strategy here saves a lot of frustration.
Do a walk-through before you unload
Before the boxes come off the truck, take five minutes to walk the empty house. Open every door, test the light switches, check that windows lock, and note anything that looks damaged or unfinished. If you’re moving with professional movers, this is also when you’ll want to note any damage to your belongings for a possible claim.
Clean before you fill the rooms
An empty house is far easier to clean than a full one. If time allows, wipe down cabinets, shelves, and bathrooms — or the spaces you can’t easily reach later — before furniture arrives. Many buyers also replace toilet seats and swap the HVAC air filter on day one for a simple fresh start.
Unpack the essentials first
Resist the urge to open every box at once. Set up the bedroom so you have somewhere to sleep, then the bathroom, then the kitchen. Keep an “essentials box” — toiletries, phone chargers, a few dishes, medications, a change of clothes — accessible so your first night is comfortable even if most boxes stay sealed.
Handle the paperwork and details
Once the house is functional, tie up the administrative loose ends that are easy to forget in the shuffle.
- File a change of address with the postal service, and update your bank, employer, insurance, and subscriptions.
- Collect every key and opener. House keys, mailbox key, garage remotes, and any community or amenity passes.
- Update your driver’s license and vehicle registration if you moved to a new state. If you’re new to Texas, there are specific deadlines to meet.
- Locate important documents from closing and store them somewhere safe.
- Meet the neighbors and learn trash and recycling pickup days — small things that help a new place feel familiar fast.
Frequently asked questions
What should I do the very first day I move in?
Prioritize safety: change or rekey the locks, test the smoke and carbon monoxide detectors, and locate your main water shutoff and electrical panel. After that, confirm your utilities are on and set up beds so you have a comfortable first night. Everything else can wait.
Do I really need to change the locks on a house I just bought?
It’s strongly recommended. You can’t know how many copies of the old keys exist or who has them. Rekeying or replacing every exterior lock is inexpensive relative to the peace of mind it buys, and it’s easiest to do before you’re fully unpacked.
How do I find my water shutoff valve?
Look where the main water line enters the home — a basement, crawl space, utility closet, or near the water heater. In warmer climates it may be near an outdoor faucet or in a covered box close to the street. You’re looking for a lever or round wheel. Test that you can turn it before an emergency ever happens.
How long does it take to feel settled in a new house?
Most people get the essentials working within the first few days and feel reasonably settled within a few weeks. Focusing on safety and key systems first — rather than trying to unpack everything at once — makes the transition far less stressful.
A calmer way to move in
Moving into a new house is a lot, but it’s much easier when you tackle it in the right order: secure the home, confirm the systems, then make it comfortable. Handle the safety basics on day one and let the rest unfold over the following weeks.
