New Homeowner Move-In Checklist: What to Do in the First 30 Days

Closing day is the beginning, not the end. The first 30 days of homeownership involve a specific set of tasks that most new owners either don't know about or treat as optional — until they find out why they weren't optional.

This checklist is organized by urgency. The first section covers safety-critical items that should be done before you're fully unpacked. The rest follow in sequence.

Day 1-3: Safety Fundamentals First

Locate and test every utility shut-off. Before you do anything else, find the following and verify they work:

• Main water shut-off valve: Typically where the supply line enters the foundation — basement, crawlspace, or utility area. Gate valves require multiple clockwise turns; ball valves require a 90-degree handle rotation. Turn it yourself on day one. Don't wait until water is flowing where it shouldn't be.
• Individual fixture shut-offs: Under every sink, behind every toilet. These allow you to isolate a single fixture without shutting off water to the whole house.
• Electrical main breaker: Located in the service panel. Identify which breaker is the main, and confirm all individual circuits are labeled accurately. Unlabeled panels create dangerous guesswork during emergencies.
• Natural gas meter: If your home has gas service, locate the meter and the shut-off valve. Keep a crescent wrench accessible nearby. In a gas emergency, turning the valve 90 degrees stops flow immediately.

Change all locks. You don't know who has copies of the previous owner's keys — contractors, neighbors, relatives, former tenants. Rekeying locks costs $25-$75 per lock through a locksmith, or you can replace deadbolts yourself for $30-$60 each. Smart locks with keypad entry eliminate the issue entirely.

Test every smoke and carbon monoxide detector. Press the test button on each unit. If any detector is over 10 years old (check the manufacture date on the back), replace it — the electrochemical sensor degrades regardless of whether the unit chirps or passes the button test. Carbon monoxide detectors have a 5-7 year service life. If there's any doubt about age, replace them.

Document the electrical panel. Photograph the breaker panel with each circuit labeled. Add labels for anything that's missing or unclear by testing: turn off a breaker, then walk through the house to identify what lost power. A fully documented panel is a significant time-saver during any electrical issue.

Week 1: Systems Documentation

Locate and photograph all appliances' model and serial numbers. Refrigerator, water heater, furnace/heat pump, AC unit, dishwasher, washer, dryer, garbage disposal. Photograph the nameplate on each. Store photos in a dedicated folder — phone or cloud. When a warranty question arises or a technician needs the model number, you'll have it instantly rather than pulling the unit away from the wall.

Find all manufacturer manuals. Check the kitchen drawers and utility area — sellers sometimes leave them. If not, model numbers from your photos let you download PDFs from manufacturer websites. Manuals contain maintenance schedules, error code explanations, and warranty terms specific to your unit.

Note the age of every major system. Water heater: manufacture date is on the rating label (often encoded in the serial number). Furnace and AC: usually on the data plate near the burner. Roof: ask the sellers, check permit records, or have a roofer assess. Knowing approximate ages tells you which systems are in their end-of-life window and which aren't.

Service life reference:

• Water heater: 8-12 years
• Furnace: 15-20 years
• Central AC: 15-20 years
• Asphalt shingle roof: 20-30 years

Set up a home maintenance folder. Digital or physical — whichever you'll actually use. Store appliance records, warranty documents, service invoices as they accumulate, and your inspector's report. This folder is the foundation of your home's maintenance history and has real value at resale.

Week 2: Physical Inspection Walkthrough

Walk every inch of the property with fresh eyes. After the initial chaos of moving, do a slower, methodical inspection:

• Roof from the ground: Binoculars work well. Look for missing, curled, or damaged shingles; sagging at the ridge line; compromised flashing around chimney and vents.
• Foundation perimeter: Look for cracks wider than hairline, evidence of water staining or efflorescence (white salt deposits that indicate moisture penetration), and verify that grading slopes away from the foundation.
• Basement or crawlspace: Check for moisture, efflorescence, daylight through cracks, or signs of previous water entry (tide marks on concrete, rust stains, warped wood).
• Attic: Look for daylight through the roof deck, insulation blocking soffit vents, and bathroom fan ducts that terminate into the attic instead of to the exterior — a common defect that causes mold.
• All windows and exterior doors: Check caulking and weatherstripping condition. Feel for drafts on a windy day.

Note any deferred maintenance items from the inspection report. Your home inspection report was a snapshot. Anything flagged as "monitor" or "recommend repair" needs to be triaged by urgency. Items involving water, structural movement, or safety systems are time-sensitive. Cosmetic items can wait.

Week 3-4: First Maintenance Tasks

Replace the HVAC filter. Even if the previous owners claimed they just replaced it. You don't know their maintenance history, and a fresh filter gives you a clean baseline and ensures you're starting with known good airflow. Find the correct size (printed on the current filter's cardboard frame) and replace it. Set a calendar reminder for the next replacement at 60-90 days for 1-inch filters.

Schedule HVAC professional service if appropriate. If you closed in fall, schedule furnace service before the first heating demand. If you closed in spring, schedule AC service before summer heat. These tune-ups cost $80-$200 and are the single most high-value professional service for the first year.

Pour water through all unused drains. Guest bathrooms, basement floor drains, laundry standpipes that haven't been used recently — run water through each for 15-20 seconds. P-traps (the curved pipe under fixtures) hold a water column that blocks sewer gas. If the previous owners left a drain unused for months, the trap may have dried out, allowing hydrogen sulfide and methane to enter the home.

Establish your contractor network. Ask neighbors on Nextdoor or local Facebook community groups for recommendations: HVAC, plumber, electrician, handyman. Get names before you need them urgently. Contractors who come through word-of-mouth from satisfied neighbors are significantly less likely to price-gouge a clearly new homeowner.

The Ongoing Rhythm

The first 30 days establish your baseline. After that, home maintenance follows a monthly, seasonal, and annual rhythm that becomes habit after the first year.

The First-Year Homeowner Maintenance Calendar covers the full 12-month cycle — monthly tasks, seasonal checklists for spring, summer, fall, and winter, appliance care schedules, and a DIY vs. hire-out decision framework for every major system. If you're in the first few months of ownership, it's the most complete starting point for building that rhythm without missing critical tasks.

Canadian homeowners have the same checklist with the additional urgency of freeze timing — the irrigation winterization and outdoor hose disconnection deadlines arrive earlier in Alberta and Saskatchewan than they do in Vancouver. The framework is the same; the calendar adjusts to climate.
