First things to do after you move in

The keys are yours — now what? Moving in is overwhelming, so do it in order. A few of these are about safety and come first; the rest are the practical setup that quietly saves you time, money, and stress later. You don’t have to do it all on day one, but do the top of this list early.

1. Safety first: alarms and shutoffs

Before anything else, make sure the home can warn you and that you can shut it down in an emergency.

• Smoke and carbon-monoxide alarms.Confirm there’s a smoke alarm on every level, inside each bedroom, and outside each sleeping area. Test every alarm, and replace any unit that’s more than 10 years past its manufacture date (printed on the back). Keep CO alarms a safe distance from fuel-burning appliances.
• Find the shutoffs. Locate the main water shutoff, the electrical panel, and the gas shutoff now, while it’s calm. Tag the water valve and make sure everyone in the household knows where it is. For gas, call your gas company to learn the right procedure — and if you ever smell gas, leave first, then call from outside.

2. Change or rekey the locks

You have no idea how many keys are out there — previous owners, agents, contractors, dog walkers. Rekey or replace the locks on every entry door as soon as you take possession. It’s a small cost for knowing exactly who can get in.

3. Label the breaker panel

Open the electrical panel and label each breaker to the room or circuit it controls. Ten minutes now saves you flipping every switch in the dark when you need to kill power to one outlet later.

4. Find the HVAC system and change the filter

Locate the heating and cooling system and replace or clean the air filter— you don’t know when it was last done. A clean filter can meaningfully cut the system’s energy use and helps it last; plan to change it every month or two going forward.

5. Set up utilities and your address

• Transfer the utilities— electric, gas, water, internet — into your name so nothing lapses.
• File a change of addressthrough the official USPS site (there’s a small identity-verification fee; standard mail forwarding runs about a year). Skip the look-alike sites that charge far more for the same free form.

6. Make a home inventory and check your insurance

Walk through with your phone and photograph or film each room — note what things are, where you bought them, and roughly what they cost, and flag valuables like jewelry that may need extra coverage. Store the inventory somewhere offsite (the cloud works). If you ever file a claim, you’ll be glad it exists. While you’re at it, confirm your homeowners policy is active from day one.

7. Clean, then settle in

It’s far easier to deep-clean an empty house than to work around furniture, so clean before you fully unpack. Then find the water heater, learn the home’s other systems (sump pump, sprinklers, septic if you have them), and update your address on your license, bank, and accounts as you go.

Do the safety items first, knock out the setup over the first week or two, and the rest can happen at your own pace. A little order up front turns a chaotic move into a home you actually know how to run.
