New Homeowner Checklist: 4 Things to Do the First Week

The first week in a new home is the time to handle four things that protect you before anything goes wrong: find the shutoffs, change the locks, test the detectors, and map the breaker panel. None takes long, and each one saves you a frantic scramble later — the difference between a confident new owner and a stressed one.

Where are the main water and gas shutoffs?

Locate the main water and gas shutoffs on day one — before you ever need them. If a pipe bursts or you smell gas, you need to stop the flow in seconds, not spend ten minutes searching. Find the main water valve (often near where the line enters, the basement, or a meter box) and the gas shutoff, and make sure everyone in the house knows where they are.

Should I change the locks on a new house?

Yes — rekey or replace every exterior lock. You have no idea how many copies of the old keys exist — previous owners, agents, contractors, neighbors. Rekeying (cheaper) or replacing the locks the first week is the simplest way to actually control who can enter your home. Consider a smart lock while you're at it.

Why test the smoke and CO detectors first thing?

Because you can't assume the previous owner kept them working. Test every smoke and CO detector, replace any dead batteries, and check the manufacture dates — replace any unit over ~10 years old. Confirm there's coverage on every level and outside bedrooms. It's the fastest, highest-value safety task — see our detector schedule and fire-safety basics.

Why label the breaker panel?

When a breaker trips (and it will), a labeled panel turns a confusing hunt into a five-second fix. Walk the house with a helper, flip each breaker, and note which room or appliance it controls. A clear panel map is one of those small things that pays off every time something goes dark.

Frequently asked questions

What else should new homeowners do first?

Find the HVAC filter and change it, locate the water heater, do a quick roof and exterior look, and note appliance models. Then settle in.

How do I know if detectors are too old?

Check the manufacture date printed on the back. Smoke alarms are generally good for 10 years, CO detectors often 5–7. Replace anything past its date.
