New Homeowner Checklist: First 30 Days

You just closed. The keys are in your hand, the movers are three days out, and every homeowner you know has a war story they wish they'd known first. This new homeowner checklist covers the exact tasks — legal, safety, financial, and organizational — to knock out in your first 30 days so year two doesn't punish you for skipping year one.

Week one: safety and access

The seven days after closing are about locking the house down and knowing what you own.

• Change every exterior lock or rekey. You don't know who has copies. A locksmith rekeys a whole house in about an hour for less than replacing one lock.
• Reprogram the garage door opener and any smart-lock codes. Delete any codes named for contractors, agents, or previous owners.
• Locate the main water shutoff, gas shutoff, and electrical panel. Photograph each with the label showing. Test the water shutoff — most home floods happen because the valve seized.
• Test every smoke and carbon monoxide detector. Replace batteries in all of them on move-in day. Any older than 10 years get replaced entirely.
• Walk the electrical panel and label every breaker with a partner flipping them one at a time. Future-you at 11pm during a tripped breaker will thank current-you.

Week two: document what you own

Every appliance, HVAC unit, and system in the house has a serial number, a purchase date (that you don't know), and a warranty clock ticking. The best time to inventory is before your stuff hits the boxes.

• Photograph every serial plate — furnace, A/C, water heater, all major appliances, garage door opener, sump pump. Store in one place, not scattered in your camera roll.
• Record install dates from the seller's disclosures before you lose the file. Age is the biggest factor in when each system fails.
• Save every manual as a PDF. Most manufacturer sites have them; a quick model-number search beats digging through a drawer at 8pm on a Sunday.
• Start a digital home inventory for insurance purposes — the walkthrough is fastest when rooms are still mostly empty. A dedicated tool like MaintFolio's home inventory stores photos, serials, and receipts in one place and exports the format insurers actually want at claim time.

Week three: schedule the pros

Booking the right services in month one prevents the majority of early-ownership surprises:

• HVAC service. Full tune-up on both furnace and A/C. The tech will tell you how many years the system has left, which you need for budgeting.
• Chimney sweep and inspection if there's a fireplace. Skip only if the seller can prove one in the last 12 months.
• Roof inspection if the seller's disclosure is fuzzy or the roof is over 12 years old.
• Septic pump if applicable — every 3–5 years, and you don't know when it last was.
• Water quality test if you're on a well.
• Pest inspection — termites, carpenter ants, and rodents don't show up on most home inspections.

Week four: paperwork and money

These aren't fun, but they're the tasks that cost real money if you skip them.

• File the homestead exemption (if your state has one). Deadlines vary — some states are strict about the year you take title.
• Update your homeowners insurance once you've inventoried valuables. Confirm replacement cost, not actual cash value, and check flood/earthquake coverage gaps.
• Update your address with USPS, DMV, employer, banks, and the IRS (Form 8822).
• Save the closing disclosure and settlement statement in cloud storage. You'll need them for taxes for as long as you own the house.
• Set up a home maintenance budget. Plan on 1–4% of home value per year for upkeep and repairs. Underfunding this is the #1 way first-time owners get financially blindsided.

First-year habits that pay for a decade

Habits, not heroics, separate homeowners whose house appreciates from ones whose house drains them. In year one:

1. Run the monthly 15-minute check. HVAC filter, smoke detectors, quick leak hunt. See our complete home maintenance checklist for the full monthly and seasonal cadence.
2. Log every service, every receipt. When you eventually sell, a documented maintenance history raises buyer confidence and appraised value.
3. Update your home inventory quarterly. Add new purchases as they happen — a stale inventory is almost as bad as none.
4. Track your utility bills. A slow creep in the water bill is almost always a hidden leak. In the gas bill, it's a heat exchanger.

Print-this-page mini checklist

If you only take one thing from this page, print this shortlist:

• Change locks, test detectors, label the panel
• Photograph every serial plate; save every manual
• Book HVAC tune-up, chimney sweep, pest inspection
• File homestead exemption, review insurance
• Start a home inventory and maintenance log

The 30/60/90-day view for busy owners

If the week-by-week breakdown feels like too much, collapse it into three horizons:

• Day 1–30 (safety + baseline): Locks, detectors, shutoffs, serial-plate photos, insurance walkthrough, HVAC tune-up booked.
• Day 31–60 (systems + records): Chimney, roof, septic, pest, and water quality checks completed. Manuals and warranties filed digitally. First month of utility bills logged as a baseline.
• Day 61–90 (habits + budget): Homestead exemption filed. Reserve fund started (1–4% of home value/year). Monthly 15-minute check on the calendar. If you own a car alongside the house, a car maintenance log uses the same discipline and is worth setting up in the same week.

Five mistakes new homeowners make in year one

1. Skipping the dryer vent. Lint buildup is the leading cause of dryer fires. Our dryer vent maintenance guide walks through a 20-minute annual clean.
2. Assuming the seller's inspection is enough. A general home inspection isn't a chimney, septic, or pest inspection. Book specialists in month one.
3. Never doing an inventory until after a loss. If you live in a wildfire, flood, or hurricane zone, pair the inventory with a wildfire evacuation checklist so claim paperwork isn't the thing you build during a disaster.
4. Under-insuring for replacement cost. Actual cash value pays out depreciated — often 40–60% less than what it costs to actually replace things.
5. Losing every receipt. Capital improvements reduce your taxable gain when you eventually sell. A photo of the receipt at purchase time is worth thousands later.

New homeowner FAQ

What's the very first thing to do after closing?

Rekey or change every exterior lock the same day you take possession. You have no way of knowing how many keys are floating around from previous owners, contractors, cleaners, or agents. A locksmith rekeys a full house in about an hour and it's cheaper than replacing hardware.

How much should I budget for home maintenance in year one?

Plan on 1–4% of the home's value per year. A newer home in a mild climate lands near 1%; an older home or one in a harsh climate lands closer to 4%. Underfunding this line item is the number-one reason first-year owners feel financially blindsided.

Do I really need a home inventory if I'm not filing a claim?

Yes — the value of an inventory is that it exists before a claim. Insurers pay faster and higher with documented proof of ownership, and the walkthrough is fastest during move-in when rooms are still empty. A digital home inventory also doubles as a warranty tracker and a resale document later.

How do I keep track of home maintenance without letting it slide?

Two habits do 80% of the work: a 15-minute monthly check (filter, detectors, quick leak hunt) and logging every service call the day it happens. A dedicated tool that reminds you and stores service history in one place beats a spreadsheet — spreadsheets are abandoned by month four. See our complete home maintenance checklist for the full seasonal cadence.

What paperwork do I need to keep, and for how long?

Keep the closing disclosure and settlement statement for as long as you own the house (they matter at tax time on sale). Keep appliance and system warranties for the length of the warranty plus one year. Keep receipts for any capital improvement — new roof, HVAC, addition, kitchen — for the entire time you own the home. Everything else can go after three tax years.

The move-in month is your one shot at a clean baseline. Set it up once with a tool that tracks assets, warranties, and service history — and you'll spend the next ten years managing your home instead of reacting to it. Start your MaintFolio account and get your new home organized in an afternoon.
