First-Year Home Maintenance Checklist: What Actually Matters in Your First 12 Months

By Leo · HomePlaybook · Updated August 2026 · 11 min read

You just closed on a house, and somewhere between the movers leaving and the first strange noise from the attic, the question hits you: what am I actually supposed to be doing right now?

Most new homeowners handle this one of two ways. They do nothing until something breaks, or they try to do everything at once off a 200-item list they found online and burn out by week three. Both cost money. The fix is a short list, correctly ordered, so you spend your first year on the ten things that actually prevent five-figure problems instead of the ninety things that don't.

This is that list. It's organized by timing, not alphabet, and every task tells you whether it's a DIY job or a call-a-pro job before you start.

How This Checklist Is Prioritized

Every task on this page is ranked by four filters, in this order:

Tasks are grouped into three tiers: Critical (first 30 days), High Priority (first 90 days), and Ongoing/Seasonal (the rest of year one).

Why the first 30 days matter more than the rest of the year combined

Reporting in June 2026 found the five biggest US home insurers closed 44% of claims last year without paying, most often for lack of documentation. Your first 30 days are when you build that documentation, before furniture and before anything can go wrong. Skip that window and you're rebuilding your evidence case after the fact, which is a much weaker position.

First 30 Days: Critical Tasks

Do these first, in roughly this order. Nothing else on this page matters if a pipe bursts and nobody knows where the shutoff is.

Week 1 Priorities

Locate and physically test your main water shutoff Label it with red tape. Turn it off and back on so you know it works before you need it under pressure. DIY · 10 minutes
Locate and test your gas shutoff Same logic. A shutoff you've never touched is a shutoff you'll fumble in an emergency. DIY · 10 minutes
Test every smoke and CO detector, replace batteries Working smoke alarms cut your risk of dying in a home fire by more than half, per NFPA. DIY · 15 minutes
Change the HVAC filter and note the size on the panel You'll need that size again in 1-3 months. Write it down now so you're never guessing at the store. DIY · 5 minutes, $15-$40
Test all GFCI outlets Kitchen, bathrooms, garage, exterior. Push test, then reset. Any that don't reset need an electrician. DIY · 15 minutes
Walk the exterior after the first rain Photograph any pooling water or grading issues. This is the cheapest foundation problem you'll ever catch. DIY · 20 minutes
Photograph every room, all four exterior sides, and every major system Store it in a dated cloud folder, not just your camera roll. This is your insurance baseline. DIY · 30-45 minutes

First 90 Days: High-Impact Foundation Tasks

Once the critical safety items are done, shift to the systems that create expensive problems if they sit ignored through your first spring or fall.

Weeks 2-12 Priorities

Clean gutters and downspouts, flush test with a hose Clogged downspouts cause an estimated 70% of basement water issues, according to contractors in the field. DIY · $0-$50, or $100-$350 pro
Visual roof inspection from the ground Missing shingles, flashing gaps, granule loss. Binoculars are fine. Anything you spot goes to a pro. DIY check · $125-$350 pro inspection
Check the attic for moisture, mold, or pest signs Open the hatch and trust your nose. A musty smell now is a $500 fix. The same smell in fall is $5,000. DIY · 15 minutes
Book a professional HVAC tune-up if not done in the last 12 months An unserviced system is a much bigger gamble in 2026, since R-410A refrigerant recharges now run $400-$800. Pro · $100-$300
Deep-clean the dryer vent NFPA counts roughly 16,000 dryer and washer fires a year, 92% of them dryers, and the leading cause is a vent that was never cleaned. DIY · $0, or $120-$250 pro
Test your sump pump, if you have one Pour a bucket of water into the pit and confirm it kicks on and clears. A failed pump in a storm means a flooded basement. DIY · 5 minutes

Months 4-12: Monthly and Seasonal Schedule

Tasks You Should Almost Never DIY in Year One

These look manageable to a new homeowner and regularly turn into the most expensive mistakes on this whole list.

Always Hire: Non-Negotiable

Any electrical work beyond changing a fixtureWarm outlets, breaker work, and new circuits are fire and shock risks that require a licensed electrician.
Gas line or plumbing work inside wallsA hidden mistake here does not show up until it's a flood or a gas leak.
Roof repairs or full inspectionsBoth a safety issue and a warranty issue if done wrong. Get a licensed roofer.
Foundation concerns of any kindMonitor and photograph, but never attempt a foundation fix yourself.
Tree removal near the houseBranches within 10 feet of the roof are a job for a licensed arborist, not a weekend project.
Structural modifications or anything requiring a permitIf it needs a permit, it needs a licensed contractor pulling it.
The Golden Rule

If it involves electricity, gas, the roof, foundation, or structural elements, hire a licensed professional. The cost of getting it wrong always exceeds the cost of hiring right.

Realistic First-Year Cost Ranges

Budget 1-2% of your home's value annually for maintenance. On a $400,000 home, that's $4,000-$8,000 a year. Here's roughly where that lands depending on how much you handle yourself.

ScenarioTypical RangeWhat It Assumes
Strategic DIY$1,000-$2,500You handle filters, caulking, gutters, and minor plumbing yourself, and hire out HVAC, roof, and electrical
Realistic average$2,500-$5,000A mix of DIY and pro work, plus one unplanned repair most homeowners hit in year one
All-professional$4,000-$8,000+Every task hired out, no DIY at all
Big-ticket surprise if ignored$8,000-$20,000+A roof leak, basement flood, or HVAC failure that was caught late instead of early

Frequently Asked Questions

How much should a new homeowner budget for maintenance in the first year?

Set aside 1-2% of your home's value for the year. On a $400,000 home that's $4,000-$8,000, covering routine service plus a buffer for the one thing that always comes up. Stay on top of small tasks and you'll land closer to the low end.

What's the single most important maintenance task in the first 30 days?

Locate and physically test your main water shutoff. Water damage claims average $13,954, and most of that damage happens in the minutes before someone finds the valve. Test it, don't just look at it, and label it clearly.

Should I get a home warranty as a new homeowner?

It depends on your systems' age. A warranty can make sense if your HVAC, water heater, or appliances are already older. It's less valuable right after a full inspection with newer systems, since warranties often exclude pre-existing conditions and still charge service call fees.

How often should I really change my HVAC filter?

Every 1-3 months, depending on filter type, pets, and system runtime. Write the filter size on the panel door the first time so you're never guessing at the store.

When should I call a professional instead of doing it myself?

Anything involving electricity, gas, the roof, foundation, or structural elements goes to a licensed professional every time. The cost of getting it wrong always exceeds the cost of hiring right.
