After a fire or a burglary, the first thing your insurer asks for is a list of what you lost — and the second thing is proof. Not a memory, not a rough guess, but an itemized list with approximate purchase dates, replacement values, and photos or receipts for anything valuable. Claims without documentation get lowballed, because adjusters cannot pay for what they cannot verify. A printed, dated inventory with photos is the single strongest thing a policyholder can bring to a claim, and it is also the document almost nobody has made — because it sounds like a weekend of paperwork. It is not. Our free Home Inventory tool turns the job into a room-by-room walkthrough: add a room, list what is in it with an estimated value and an optional photo, and everything saves automatically in your browser. When you are done, print a clean inventory document for your insurance file and download a JSON backup for safekeeping. This guide explains how to build one properly, how to value what you own, and the mistakes that quietly make an inventory useless when it matters most.
Step one: add your rooms. Create a room for each space — living room, bedroom, kitchen, garage — and set your currency once. Walk the house with your phone and work room by room, so nothing gets skipped and nothing gets counted twice. Step two: list the items inside each room. Add each item with an estimated value and, where it matters, a photo. Big items get their own line — the TV, the laptop, the couch — and small items get grouped by category, for example "kitchen utensils — $300" or "linens — $200". Photograph the serial numbers on electronics: they prove ownership and the exact model, which is exactly what an adjuster needs. Step three: print or back up. Print a clean inventory document for your insurance file, and download a JSON backup. Browser storage can be cleared, so the backup is not optional — it is the copy that survives a new phone or a cleared cache. Most people finish a two-bedroom home in about three hours with photos, which is one Saturday afternoon for a document that can be worth thousands in a claim.
Use replacement cost: the price to buy the same item new today — not what you paid for it. That distinction is the one that costs people money. A five-year-old TV you bought for $900 might cost $600 to replace today, or $1,100 if the equivalent model went up in price; what matters is today's shelf price, not the receipt in your drawer. Check current retail prices for big items (TV, laptop, couch) and group small items by category. Update values yearly, because inflation moves them. And expect a surprise: most two-bedroom renters are surprised to find $20,000–$35,000 in belongings once everything is listed. The couch, the bed, the kitchen, the clothes in the closet, the electronics on the desks — individually they feel small, and together they are the price of a car. That surprise is the point of the exercise: the number is what your insurance actually has to cover, and most people insure far less than they own because they never added it up.
Take a two-bedroom apartment done in one Saturday afternoon: 6 rooms, 86 items catalogued in about 3 hours with photos. Electronics $8,400, furniture $9,200, clothing $4,100, kitchen and misc $2,600 — $24,300 in total. The list was printed to PDF and emailed to the insurance agent the same day. Six months later a burst pipe ruined the living room, and the inventory turned a vague claim into an itemized one: every damaged item already had a photo, a value and a room, so there was nothing to reconstruct from memory while standing in a wet living room. The claim settled in 3 weeks instead of 3 months. That is the whole case for doing this before anything happens. After a loss, you are reconstructing a list of things you no longer have, from a home you cannot walk through, while stressed. Before a loss, you are walking through your own home with your phone. The work is identical; only the timing is different, and the timing is everything.
Listing what you paid instead of replacement cost. Insurers settle on what it costs to replace the item today, so a list built on old receipts understates your claim from the first line. Skipping photos of serial numbers. A photo of a TV proves you owned a TV; a photo of its serial-number plate proves you owned that exact model, which is what stops an adjuster from pricing the cheapest equivalent. Grouping everything. Low-value items belong in groups, but valuables need their own lines — a $1,200 laptop buried inside "electronics — $3,000" is invisible when it matters. Never backing up. The inventory lives in your browser; clear your browsing data without a backup and it is gone. Download the JSON after every big update and keep it somewhere that is not the same device. Treating it as a one-time job. A new laptop, a new couch, a gifted watch — update after any major purchase, and once a year overall. Fifteen minutes with your phone camera keeps it current. Confusing documentation with an appraisal. This is a record, not a legal valuation: insurers may still ask for receipts on high-value items, and your policy terms govern what is actually covered.
The honest limits are four. First, storage lives in this browser only — the inventory is saved on the device you made it on, and clearing browsing data erases it unless you have the JSON backup. Second, photos are compressed to fit storage limits (around 5 MB), so very large photo sets need the backup-and-trim routine: download a backup, remove some photos, and keep going. Third, moving to another device takes a deliberate step — download the backup JSON on the old device, move the file over, then restore from JSON on the new one. Fourth, this is documentation, not a legal appraisal, and it does not change your policy: your coverage limits, deductibles and exclusions still govern what gets paid. Within those limits, the tool does one job completely: it turns an afternoon's walk through your home into a dated, itemized, photographed record that an insurer can actually work from. An inventory lists what you own; an inspection records the state of the place itself. For a new tenancy, start with the Move-In Inspection Checklist, then keep the inventory for the contents — and if you freeze food in bulk, the Freezer Inventory Tracker applies the same habit to a different shelf. The companion guides are our stain removal guide, for keeping the things on the list in good shape, our medication tracker guide, for another household list worth keeping current, and our mileage logbook guide, for the same record-keeping habit applied to your car.
