7 Things You MUST Do the First Week in Your New Home

The first week in a new home is a mess. Boxes everywhere, you can’t find the scissors, and you’re not sure which bag has your toothbrush. It’s exciting, but it’s also a lot.

Here’s the thing though: what you do in that first week actually matters. It’s not just about unpacking. It’s about making your new place safe, comfortable, and actually feel like yours. Skip these steps now, and you might end up dealing with bigger headaches (or bigger bills) down the road.

So before you get lost in decorating or figuring out where the couch goes, let’s walk through the 7 things you really shouldn’t put off. None of them take long, and doing them now will save you a ton of stress later.

1. Change the Locks

Here’s a question you probably haven’t thought about: who else has a key to your house?

Think about it. The old owners might have made extra copies for family. A contractor who worked on the place years ago could still have one. Maybe an old renter never gave theirs back. You have no way of knowing how many keys are floating around out there — and that’s not a great feeling when it’s your home now.

The fix is simple: change the locks. Like, this week. It’s one of those jobs that feels like a hassle but takes way less time and money than you’d think.

A few things to cover, not just your front door:

The back door and garage too
Any keypad codes (garage door, alarm system) — reset these to a new code only you know
Smart locks — same deal, update the passcode or app access

You’ve got two easy ways to handle it:

Call a locksmith. They’ll usually charge somewhere between $50 and $150, and it’s done in an hour.
Do it yourself. Hardware stores sell rekey kits for way less, and honestly, it’s a pretty simple job even if you’re not handy. There are plenty of videos online walking you through it step by step.

Either way, don’t skip this one. It’s the easiest peace of mind you’ll get all week.

2. Locate and Test Safety Essentials

If there was a gas leak right now, would you know how to shut it off? What about the water, if a pipe burst?

If you’re not sure, don’t worry — most people aren’t when they first move in. But this is exactly the kind of thing you want to figure out before you need it, not during an emergency when you’re panicking and Googling “where is my water shutoff” at 2am.

So take a walk around your new place and find these three things:

The main water shutoff. This stops water flowing to your whole house. Usually near where the water line enters your home (basement, garage, or outside near the street).
The gas shutoff. If you have gas, find this valve too. It’s often near your gas meter outside.
The electrical panel. This is your breaker box — good to know where it is if something trips or you need to cut power to a room.

While you’re at it, check the smoke detectors and carbon monoxide detectors. Don’t just assume they work because they’re already installed — press the test button on each one. If you hear a weak beep or nothing at all, swap in fresh batteries right away. This isn’t a “get to it eventually” task — it’s genuinely one of those things that can save your life.

Same goes for any fire extinguishers in the house. Find them, and check the little gauge on the side to make sure they’re still charged and not expired.

Last thing: if you’re in a house with multiple floors, walk through and figure out your exits. Where would you go if there was a fire upstairs? Having an answer in your head now means you won’t be figuring it out in a panic later.

None of this takes more than 20-30 minutes total, but it’s 20-30 minutes that genuinely matters.

3. Deep Clean Before You Fully Unpack

Okay, this one’s less about “must-do for safety” and more about “you’ll regret skipping this.” Here’s why: right now, your rooms are empty (or close to it). That’s actually the best time to clean, because once your furniture and boxes are everywhere, cleaning gets ten times harder.

Even if the place looked clean when you walked through it, you don’t really know how the last people lived there. So it’s worth giving everything a solid once-over before you settle in.

Focus your energy on these spots first:

The kitchen. Wipe out the inside of cabinets and drawers before you fill them with your stuff. And don’t forget the fridge — clean the shelves and drawers even if it looks fine.
The bathrooms. Toilets, sinks, showers, and don’t skip behind the toilet (you know why).
The floors. A good vacuum and mop everywhere, especially if there was carpet — you’d be surprised what’s hiding in there.

If you moved into a place where you have no idea who lived there before, or the previous owners had pets you’re not used to, it might be worth paying for a professional deep clean. It’s not required, but for some people it’s worth the peace of mind — especially if anyone in your house has allergies.

Bottom line: 30 minutes of cleaning now, while the rooms are still empty, saves you hours of cleaning around furniture later.

4. Check and Service Key Systems

Your new house came with a bunch of systems you’re now in charge of — heating, hot water, appliances, all of it. Before you get too comfortable, it’s worth spending a little time making sure everything actually works the way it should.

Start here:

Replace the HVAC filter. This is the filter for your heating and cooling system, and you genuinely have no idea how old the current one is or how long it’s been in there. A fresh filter means cleaner air and a system that doesn’t have to work as hard. While you’re at it, set up your thermostat — figure out how it works, and program it if it’s the smart kind.
Check the water heater. Look for any rust, leaks, or weird smells around it. You don’t need to be an expert — just eyeball it and make sure nothing looks off.
Test your appliances. Run the dishwasher, oven, washer, and dryer at least once. It’s way better to find out now that something’s broken than three weeks from now when you actually need it for something important.
Look under every sink and around every toilet. Just a quick check for drips or water stains. Small leaks are way easier (and cheaper) to fix before they turn into big problems.

This whole check might take an hour, but it’s the kind of hour that can save you from a surprise repair bill later.

5. Update Your Address Everywhere

This one’s not exciting, but it matters — and it’s way easier to knock out in one sitting than to remember piece by piece over the next few months.

Here’s your list:

Set up mail forwarding with USPS. Do this first, since it catches anything you forget to update elsewhere. It takes five minutes online.
Update your driver’s license and car registration. Most states give you a set window of time to do this after you move, so don’t put it off too long.
Update your banks and insurance. Think checking accounts, credit cards, health insurance, car insurance — anywhere your address is on file.
Update your subscriptions and employer. Streaming services, online shopping accounts, your job’s HR system — basically anywhere a package or important letter might get sent.
Update your voter registration. So you’re set up to vote in the right district next time there’s an election.

Pro tip: make a simple list of every place your old address is on file, then knock them out over a lazy afternoon. It feels tedious, but future-you will be really glad you did it now instead of six months from now when a bill gets sent to your old place.

6. Get to Know the Neighborhood

Your new home isn’t just the house — it’s everything around it too. Getting familiar with your neighborhood early makes everything feel less new and a lot more comfortable, comfortable, fast.

Here’s where to start:

Say hi to your neighbors. You don’t need a big introduction — just a quick “hey, we just moved in!” goes a long way. It’s nice to have a friendly face nearby, and neighbors are often your best source for local tips (best pizza place, which streets to avoid during rush hour, stuff like that).
Find the nearest hospital, pharmacy, and grocery store. You don’t want to be figuring this out for the first time during an actual emergency or when you’re out of medicine at 9pm.
Learn the trash and recycling schedule. Every neighborhood does this a little differently — figure out which days are pickup, and what bin goes where. Nothing says “new to the neighborhood” like a trash can sitting out on the wrong day for a week.
Check in with your HOA, if you have one. Get their rules, contact info, and find out about anything you’re required to do (like registering your car or getting approval before painting your front door a bold color).

None of this needs to happen all at once — just start picking it up naturally as you settle in.

7. Set Up a Home Emergency Plan

Nobody likes thinking about worst-case scenarios, but having a plan in place means you’re not scrambling to figure things out if something actually happens. It only takes a few minutes to set up, and it’s one of those things you’ll be really glad you did if you ever need it.

Here’s what to cover:

Save important numbers in your phone. Local emergency services, poison control, and the nearest urgent care or ER. Don’t just assume you’ll Google it if something happens — have it ready to go.
Pick a meeting spot. If everyone in your house talked about this, you’d have a spot to meet up outside in case of a fire or other emergency. Somewhere simple, like a neighbor’s driveway or the mailbox at the end of the street.
Look into local community alerts. Some areas let you sign up for text alerts from local police or fire departments — things like severe weather warnings or safety notices for your area. Worth a quick search to see if your city offers this.
Keep important documents somewhere safe and easy to grab. Think your house deed, insurance papers, passports, birth certificates. A fireproof box works great, and bonus points if you also scan copies and save them somewhere online, just in case.

This section might feel like the least exciting one on the list, but it’s the one you’ll be most thankful for if you ever actually need it.

Conclusion
And that’s it — 7 things that’ll make your first week in a new home way less stressful and a lot more settled.

Let’s do a quick recap: you’re changing the locks, finding your safety shutoffs, giving the place a deep clean, checking that your systems actually work, updating your address everywhere, meeting your neighbors, and putting together a simple emergency plan. That’s it. Do those seven things, and you’ve covered the big stuff — safety, security, and comfort — all in your first week.

Here’s the truth though: you don’t need to do all of this on day one. That’s a recipe for burnout, and honestly, nobody unpacks their entire house in 24 hours anyway. Instead, just pick one or two things each day. Maybe locks and safety checks on day one, cleaning on day two, and so on. By the end of the week, you’ll have knocked out everything on this list without feeling like you ran a marathon.

Moving into a new place is a big deal, and it’s easy to get caught up in just unpacking boxes and decorating. But taking care of these basics first means you can actually relax and enjoy your new home, instead of worrying about what you might’ve missed.

Grab a notepad (or your phone’s notes app), turn this list into your own checklist, and start checking things off. You’ve got this.
