A bathroom remodel looks finished the day the contractor leaves, but what's behind the tile only lives in the paperwork. To track contractor work, save a few specific records at each stage of the job: who did it, what they agreed to, what changed, and what the city approved.
What Should You Save Before Work Starts?
Save the contractor's license and insurance information, along with the signed contract, before any work begins. These confirm who you hired and what you agreed to, and both are harder to track down once the job is underway.
Contractor License and Insurance Information
Ask for the contractor's license number and proof of insurance before signing anything. Licensing rules vary by state and locality, so check what applies where you live and confirm the license is active for the type of work you're hiring for.
In California, the Contractors State License Board license lookup shows a contractor's license status, along with the workers' compensation and bond information on file. The board notes that California contractors with employees must carry workers' compensation, while general liability insurance, which covers damage to your property, is not required. Ask for a certificate of insurance either way and save it with the contract.
The Signed Contract and Scope of Work
Keep the full written contract, including the scope of work, start and end dates, materials, and payment schedule. The scope of work spells out exactly what the contractor agreed to do, which matters if you later disagree about what was included.
A verbal promise to replace a subfloor is hard to prove if it never made it into writing. Save the signed contract as a PDF or photo right after signing, before it gets buried in a truck or an email thread.
How Do You Document Work as It Happens?
Document work as it happens by saving change orders, dated photos, and the exact materials installed. Waiting until the job is finished means relying on memory for details that mattered weeks earlier.
Written Change Orders
Get every change to the original scope in writing, signed by both you and the contractor. A change order should state what is changing, why, and how it affects the price or timeline. The California license board's homeowner contract checklist makes the same point: changes and additions to a contract should all be in writing, which reduces the chance of a later dispute.
If a contractor finds rotted framing behind a wall and needs to charge extra, a signed change order explains why the final invoice is higher than the original estimate.
Photos Before, During, and After the Job
Take photos before demolition, during the work, and after it's complete, especially of anything that will be covered up. Plumbing, wiring, and framing are only visible for a short window before drywall or tile goes over them.
A photo of pipe routing before the wall closes can save a plumber guesswork during a future repair. Store photos by date and by the room or system they show, so they're easy to find years later.
Materials, Fixtures, and Model Numbers
Record the brand, model, and serial number of every major fixture or appliance installed, including water heaters, HVAC units, faucets, and built-in appliances. Photographing the full rating label is the fastest way, and this guide on finding and recording appliance model numbers shows where the labels usually are.
A model number tells a technician exactly which part to order. Keep these details with the room they're installed in, not in a general folder where they're easy to lose.
How Do You Confirm Permitted Work Was Approved?
Keep the permit number, the approved plans, and the final inspection sign-off. Work that needed a permit but never got one, or never passed final inspection, can cause problems at resale or during an insurance claim.
Permit Numbers and Approved Plans
Before signing, check that the contract says who is responsible for pulling the permits, which is one of the questions on the same state checklist. Once the permit is issued, save the permit number and a copy of the approved plans.
A permit number lets you or a future buyer look up the project's history with your local building department. Without it, confirming the work was approved means searching city or county records by address.
Inspection Results and Final Sign-Offs
Keep a copy of every inspection result, especially the final sign-off that closes out the permit. A final sign-off shows the work was inspected and approved under the code in effect at the time.
A seller who can't produce a final sign-off may face questions from the buyer's side or need to close out an open permit before the sale. If you're preparing to list, this guide to home records to keep when selling a house covers what buyers typically ask for.
What Should You Collect Before Final Payment?
Collect a punch list, the final invoice, lien waivers, and warranty terms before making the final payment. It's easier to get missing paperwork while a payment is still outstanding.
A List of Unfinished or Corrected Work
Walk through the finished job with the contractor and write down anything incomplete or needing correction. This punch list should include a date for when each item will be fixed.
A cabinet door that won't close or a switch in the wrong spot is easy to forget once you've written the last check. Have both parties sign the punch list so there's a clear record of what's outstanding.
Final Invoices and Lien Waivers
Request a final, itemized invoice and the appropriate lien waivers before releasing the last payment. A lien waiver is a signed release in which the contractor, subcontractor, or supplier gives up the right to file a lien on your home for the amount covered.
California's conditional and unconditional waiver forms show the difference. A conditional waiver is signed before the claimant has been paid, while an unconditional waiver states that payment has already been received. The board also warns that paying your contractor, or getting a release from your contractor, does not guarantee that subcontractors and suppliers were paid, so ask for waivers from them too.
Workmanship Warranty Terms and Product Information
Get the workmanship warranty in writing, separate from any manufacturer warranty on installed products. A workmanship warranty covers the contractor's labor for a period the contractor sets, while a manufacturer warranty covers defects in the product itself.
If new tile cracks a year later, knowing which warranty applies tells you whether to call the contractor or the manufacturer. Save both with the model numbers they apply to, and note the end dates in an appliance warranty tracker so you know when coverage runs out.
How Should You Organize Records for Future Repairs or a Sale?
Group each job under the room or home system it affected, not by date or contractor name. When a problem comes up in a specific room, all related records are in one place.
Group Each Job by Room or Home System
Sort contracts, photos, permits, and invoices under headings like "Kitchen," "HVAC," or "Roof." A leak in the primary bathroom should pull up every record tied to that bathroom's past work, and a buyer can get the full history of the kitchen remodel without digging through paperwork from an unrelated roof job.

Choose a Method You Can Keep Using
Pick a system you'll actually update after each job. A detailed folder structure that stops getting used after the first project is less useful than a simple one that stays current.
Here's how common methods compare:
| Method | Setup effort | Easy to find records later | Reminders for warranties | Good for a future sale |
|---|---|---|---|---|
| Paper folder or binder | Low | Moderate | No | Possible, but bulky to hand off |
| Cloud folder (photos, PDFs) | Low | Moderate, depends on naming | No | Yes, but needs manual sorting |
| Spreadsheet | Moderate | Good if kept updated | Only with calendar reminders you set yourself | Needs explaining to a buyer |
| Home management app | Low to moderate | Good if organized by room or system | Usually built in | Yes, if records can be shared or transferred |
A spreadsheet works if you're comfortable updating it after every job and setting your own reminders. A home management app is worth considering if you want each job's records grouped by room and a reminder before a workmanship warranty ends.
Frequently Asked Questions
What is a free way to track contractor work on my home?
Create a folder for each room or home system, on paper or in a cloud storage app you already use, and save the contract, photos, permits, and invoices for each job as it happens. Updating it during the project is easier than reconstructing everything afterward.
Should I track a contractor's hours if the job is billed hourly?
Yes. Ask for a daily or weekly breakdown of hours worked and keep it with the signed contract. It gives you a record to compare against the final invoice and makes billing questions easier to resolve.
How can I document plumbing or wiring before the walls are closed?
Take clear, well-lit photos of plumbing and wiring before drywall or tile covers them, including a wider shot that shows where they sit relative to a fixed point like a doorway or corner. You can also ask the contractor to note pipe and wire locations on the plans or in writing before the walls are closed.
What should I do if a contractor did not give me permit records?
First, ask the contractor for the permit number. If that doesn't work, contact your city or county building department and ask for the permit history for your address; many departments let you search or request it. If work that needed a permit was never permitted, the same department can explain what it takes to resolve it.
How long should I keep records of contractor work on my home?
Keep major project records, including permits, inspection sign-offs, contracts, and workmanship warranties, for as long as you own the home. Permit and inspection history matters at resale, and receipts for improvements can support your home's cost basis when you sell, so it pays to track home improvement receipts from the start.
