Why Preparation Makes a Real Difference

A home inspection is one of the most consequential walkthroughs a property will ever receive. Whether you're on the selling side hoping to minimize surprises, or a buyer arranging an inspection on a home you're under contract for, the condition and accessibility of the home on inspection day directly shapes the quality of the report.

Inspectors are trained to document what they see. Clutter blocking a water heater, a locked crawl space door, or a tripped GFCI outlet that nobody reset can all appear in the report as items that could not be evaluated — which creates uncertainty for everyone. A well-prepared home allows the inspector to do a thorough job and gives both parties cleaner, more actionable information.

Think of this checklist as a one-time tune-up that overlaps with the kind of routine seasonal upkeep every homeowner benefits from. Many items here take only minutes but make a meaningful impression.

Don't Attempt to Hide Known Defects

Freshly painted over water stains, caulk applied over active mold, or a recently replaced ceiling tile above a leak are patterns experienced inspectors recognize immediately. Concealing defects can create legal liability in a real estate transaction and erodes trust with buyers. If you know of an issue, document it, repair it properly, or disclose it — these are always the safer paths.

Tools and Documents to Have Ready

Before you start the physical walkthrough of your own home, gather a few key items. Having these on hand saves time and helps you answer any questions that come up.

Required

Flashlight or headlamp

Lets you check dim attic, crawl space, and cabinet areas before the inspector does.

Required

GFCI outlet tester

An inexpensive plug-in device that confirms GFCI outlets are wired correctly and functioning.

Optional

Non-contact voltage tester

Allows safe verification that circuits are live or de-energized without touching bare wires.

Optional

Caulk gun with exterior-grade caulk

Used to seal gaps around windows, doors, and utility penetrations before the inspection.

Required

Maintenance records binder or folder

Organizes permits, appliance warranties, and service receipts for the inspector's reference.

The Full Pre-Inspection Checklist

Work through each group below in any order that suits your schedule. Most homeowners find it easiest to move room by room for the interior tasks and then tackle the exterior as a final loop.

Access & Clearance

Unlock all interior and exterior doors, including the attic hatch, crawl space access panel, and any outbuildings on the property. Must
Clear a minimum 3-foot radius around the electrical panel, water heater, furnace, and any sump pump. Must
Move stored items away from basement and crawl space walls so the inspector can assess the foundation. Must
Ensure pets are secured or removed from the home so they don't interfere with the inspection or exit through an open door. Should

Plumbing & Water Systems

Test every faucet for proper hot and cold function, and fix any drips before inspection day. Must
Flush all toilets to confirm they fill and stop correctly; adjust the float mechanism or flapper if a toilet runs continuously. Must
Inspect visible pipes under sinks for moisture, staining, or corrosion — even minor drips will be noted in the report. Should
Locate and confirm the main water shut-off is accessible and clearly labeled. Should

Electrical & Safety Devices

Replace any burnt-out light bulbs throughout the home — a non-functional light may be logged as an unknown electrical issue. Must
Test and reset all GFCI (ground fault circuit interrupter) outlets, typically found in bathrooms, kitchens, garages, and near water. Must
Test every smoke detector and carbon monoxide detector; replace batteries if needed and install units in rooms where they're missing. Must
Label any unlabeled breakers in the electrical panel to make the inspector's job easier and the report more precise. Nice to have

HVAC & Ventilation

Replace the furnace or air handler filter if it hasn't been changed in the last three months. Should
Confirm the heating and cooling system turns on, runs without unusual noise, and that vents in all rooms are open and unobstructed. Must
Clear leaves, debris, and vegetation from around the exterior AC condenser unit. Should

Exterior & Roof

Walk the exterior perimeter and clear overgrown shrubs or tree branches that touch the siding or roofline. Should
Check that all gutters are free of debris and downspouts direct water at least 2–3 feet away from the foundation. Should
Note any cracked caulk around windows, doors, or where utilities enter the home, and re-caulk as needed. Nice to have

Documentation & Records

Assemble any permits pulled for past renovations, along with receipts or warranties for major system replacements such as the roof, HVAC, or water heater. Should
Leave utility bills from the past 12 months accessible if requested — they can help establish baseline energy usage. Nice to have
Write a brief note for the inspector flagging any known issues, past repairs, or quirks of the home's systems. Should

Once the inspection is complete, the report may surface items that need professional attention. If that's the case, our guide on what to ask before hiring a contractor can help you vet repair professionals and understand bids without costly surprises.

Electrical and Gas Work Requires a Licensed Professional

This checklist covers tasks any careful homeowner can handle safely. However, if your preparation uncovers signs of wiring problems — such as scorch marks near outlets, tripping breakers without an obvious cause, or the smell of gas near an appliance — stop and call a licensed electrician or your gas utility before the inspection. Do not attempt to repair these issues yourself.
