Your first month in the house: do these things

Your first month in a new house has one real job, and it is not decorating. It is learning the house: where the water shuts off, what condition the systems are in, and what the previous owner knew that you do not yet. The short list looks like this. Find and label the shutoffs. Change the locks and the HVAC filter. Test the smoke and carbon monoxide detectors. Photograph everything while it is still empty enough to see. Review your insurance while the closing documents are fresh. And start the record that the house will run on for as long as you own it. None of it is hard. All of it is dramatically easier now than at any later point.

What should you find in week one?

Three shutoffs, before you need any of them. The main water shutoff is the most important object in the house you have never thought about, because every plumbing emergency starts with someone trying to find it while water is running. Locate it, make sure it actually turns, and show everyone in the household where it is. Then the gas shutoff, if your house has gas service, and the electrical panel. Open the panel and check whether the breakers are labeled honestly. If they are not, an hour with a helper and some tape, flipping breakers and noting what dies, is one of the best hours you will spend all year.

While you are exploring, find the attic access, the crawl space or basement corners you would otherwise never visit, and the outdoor faucets. You are building a mental map of the house while curiosity is high and nothing is broken. That map is exactly what you will wish you had during your first emergency.

What should you change right away?

Locks first. You have no idea how many copies of the old keys exist, or with whom: neighbors, dog walkers, contractors, a previous owner's relatives. Rekeying or replacing the locks, and resetting the garage door keypad code, closes that question permanently for a modest cost.

Then the HVAC filter. You cannot know when it was last changed, and a fresh filter is the cheapest favor you can do your most expensive system. While you are at it, note the filter size on your phone, because you will never remember it at the store. As a rule of thumb, filters want changing every one to three months depending on the filter type, pets, and allergies, so this is also the moment to start that rhythm.

Finish with the detectors. Test every smoke and carbon monoxide detector, replace batteries you cannot vouch for, and check the manufacture dates, since detectors themselves expire. A house you just bought is a house whose safety equipment history is unknown. Make it known.

What should you photograph and file?

Everything, and now, while rooms are empty and access is easy. Photograph every room from the corners, the exterior from all sides, and, most valuably, the boring stuff: the serial number and model plates on the furnace, water heater, and every appliance, the electrical panel with its labels, the water meter, and any existing damage or quirks. These photos become your baseline for insurance, your reference for every future repair call, and your proof of condition. We wrote a full guide to what to photograph the day you move in, and it is worth doing before the boxes fill the frame.

The paper deserves the same treatment. Your closing documents, inspection report, seller disclosures, and any warranties or manuals the sellers left behind should land in one place, digitized, before they scatter into drawers. The inspection report in particular is a treasure map: it lists every known issue with the house, graded and photographed, and it is the closest thing to an owner's manual you received at closing.

What should you learn about your systems?

Their ages, mostly. The working life of a house is governed by a handful of clocks: tank water heaters typically run 8 to 12 years, furnaces roughly 15 to 20, and roofs and appliances on their own timelines, all varying with climate and care. The serial plates you photographed usually encode manufacture dates, and the inspection report often estimates ages too. Knowing that the water heater is in year nine is the difference between planning a replacement and mopping one up.

Write these ages down somewhere permanent, alongside the model numbers and the service stickers you found on the equipment. Ten minutes of transcription in month one buys you years of instant answers to the question every technician and every insurer will eventually ask: how old is it, and when was it last serviced?

What sets up the whole first year?

Two rhythms and a record. First, insurance: read your policy while the purchase details are fresh, confirm the coverage matches what you actually bought, and file the policy with everything else. Second, a maintenance calendar, because the house will now present its needs seasonally and forever. Our first-year homeowner maintenance calendar lays out what to do and when, so nothing depends on you spontaneously remembering gutters in November.

And finally, the record itself. Everything this month generated, the photos, the documents, the system ages, the filter size, the first repairs, wants to live in one place that grows with the house. This is precisely what Holm was built for, and if this is your first house, our page for first-time owners shows how the whole system fits together from day one.

There is a particular feeling available at the end of a first month done this way. The house is still new, but it is no longer a stranger: you know where its valves are, how old its heart is, and where its papers live. That quiet confidence is the real move-in, and it lasts a lot longer than the smell of fresh paint. When you are ready to give your new house its memory, Holm is a good first entry.
