The new homeowner's survival guide — what to do in your first 30 days

This article is for educational purposes only and is not a substitute for professional advice. Local codes, regulations, and best practices vary by region.

You have the keys. The closing happened yesterday, or maybe an hour ago. Now you’re standing in your house thinking about everything you don’t know. Where’s the shutoff? Who do you call if something breaks? What was that noise? Everything looks fine until it suddenly doesn’t, and you realize you have no idea what to do.

This is normal. Everyone feels this way for the first few weeks. The good news is that the first 30 days don’t require you to fix anything or make any major decisions. They require you to find three critical things, understand what you have, document what matters, and establish a baseline for how your house actually works. Do that, and your confidence will rise faster than you’d expect.

Know Where to Turn Off the Water and Gas

The single most important thing you can do in your first week is locate and label your main water shutoff and gas shutoff. If something goes catastrophically wrong—a pipe bursts, a gas line breaks—you need to be able to stop it immediately without thinking.

The main water shutoff is almost always located near where the water line enters the house. In most homes, this is in the basement, crawl space, or utility area. It’s typically a lever valve on a copper or PVC line. Turn it clockwise to shut off water to the entire house. Find it, test it (turn it off, run a faucet to confirm water stops, then turn it back on), and label it clearly with a piece of tape and a marker. Do this today.

The gas shutoff is usually located near the gas meter, often on the outside of the house or in a utility space. It’s a lever handle on the gas line itself. Unlike water, you shouldn’t test it by turning it on and off—that can trap air in the system. Just locate it, understand that it turns perpendicular to the pipe to shut off gas, label it, and commit the location to memory. If you ever smell gas, you know exactly where to go.

Find these two things first. Nothing else matters until you know where to stop the water and gas.

Locate Your Electrical Panel

The electrical panel (also called the breaker box or breaker panel) is usually in the basement, utility room, garage, or on an exterior wall. It’s a metal box, often gray or tan, usually about the size of a small medicine cabinet. This is where all the circuits in your house originate. Every light, outlet, and appliance is connected to a breaker in this box.

Open the door. Inside you’ll see a series of switches, usually arranged in two columns. Each one is labeled—or should be, though previous owners sometimes don’t label them well. Spend an afternoon mapping your panel. Take a phone photo of the inside of the door. Go through your house, turn off breakers one at a time, and figure out which breaker controls which circuits. This sounds tedious, but it’s information you’ll use for years. Write it down, take notes, update the label inside the panel door.

While you’re looking at the panel, note the main breaker. This is usually a larger switch at the top that controls the whole panel. You won’t turn this off often, but you should know where it is and understand that it kills power to the entire house.

Document Your Systems

Walk your house methodically. In the basement or utility area, locate your water heater, furnace or heat pump, air conditioning conditioner (if there is one), and any other major systems. For each one, find the serial number and model information. Take photos. Write down what you find—or better, create a simple binder where you collect this information.

These details matter if something breaks. When you call a technician, they’ll ask what model water heater you have, when it was installed, what kind of heating system you’re running. Having this information ready means you can get better answers, faster service, and more accurate repair estimates. It takes an hour to document your house properly. It will save you hours later.

Find the thermostat for heating and cooling. Learn how it works. Understand how to adjust the temperature. These systems run your utilities, and you need to know how to operate them.

Set Up Utility Accounts and Find Your Bills

Contact the utility companies (electric, gas, water, and any others for your area) and put the accounts in your name. You should have received information about this during closing, but it’s worth calling to confirm. Ask for the account numbers and service addresses. Set up online portals so you can view your bills and usage.

Your first utility bills will arrive in a few weeks. They’re worth reading carefully, even if they seem boring. Your electric bill shows your consumption in kilowatt-hours and your gas bill in therms. Water usage is measured in gallons. These numbers are your baseline. As seasons change, your usage will change—heating costs spike in winter, air conditioning costs spike in summer. But you need to know what normal looks like so you can spot problems later. If your water bill suddenly doubles with no explanation, something is leaking. If your electric bill spikes wildly, something is wrong. You can only spot these changes if you know what normal is for your house.

Review Your Home Inspection Report

You had a home inspection before closing. That report is yours—find it, and read it. Seriously read it. Don’t skim for the scary parts; read the whole thing.

Your inspection report is a snapshot of your house’s condition on the day of the inspection. It notes what works, what doesn’t, what needs attention soon, and what should be monitored. The inspector probably flagged some things that need repair or attention. Some of those items may have been addressed before closing; some may not have been. You need to know what you’re walking into.

The report isn’t a to-do list to tackle immediately. It’s information. Prioritize it: what’s dangerous or urgent (major structural issues, active leaks, electrical hazards), what’s important but not emergency (roof age, furnace condition, insulation), and what’s minor but worth knowing (cosmetic issues, small repairs). Use it to understand your house and to plan your first-year maintenance.

Create a Basic Home Maintenance Binder

Buy a simple three-ring binder. Over the next few weeks, put the following documents in it:

The home inspection report. Copies of your utility account information. The original closing documents. Warranty information for appliances. A list of all the contractors or services you’ve used—their names, phone numbers, dates of work, and what they did. Photos of your house taken before you moved in.

Later, you’ll add receipts for repairs, maintenance records, and a schedule of what needs to be done when. For now, just start collecting the baseline information. This binder becomes the definitive record of your house. When you eventually sell, you’ll hand it to the next owner. When something breaks in three years, you’ll remember exactly when it was installed and who fixed it last.

This doesn’t have to be perfect. It doesn’t have to be color-coded or beautifully organized. It just has to be consistent and findable. A three-ring binder and some page protectors cost ten dollars. The knowledge and documentation it holds is worth thousands.

Get Your Paperwork Right

Make sure your address is updated with your insurance company. Your homeowner’s insurance should be in place before you close; confirm it is. Understand what your policy covers—this will be important later.

Update your address with your employer, your banks, your credit cards, and your doctor. Change your voter registration. Update your driver’s license. These are the boring parts of moving, but they matter.

Your First Month Checklist

The first 30 days should include finding the water shutoff, gas shutoff, and electrical panel. It should include documenting your major systems and taking photos. It should include setting up utility accounts and reading your first bills. It should include reviewing your home inspection report and creating a home maintenance binder. It should include getting your insurance in place and updating your address everywhere.

You don’t need to understand how everything works yet. You don’t need to fix anything or make any major decisions. You just need to know where to start and what you’re working with. After these 30 days, you’ll have a foundation of knowledge that will make every future project easier and every future problem less stressful.

The home is now yours. You’re not moving into it blind anymore—you’re moving in informed. That confidence matters more than you realize.
