How to photograph and video every open wall before drywall

To photograph walls before drywall, visit after the rough-in work passes inspection and before insulation goes in. Film every wall and ceiling slowly with a tape measure in view, then take wide labeled photos of each room. Name files by room and wall, and keep them with your home records. The window may last only days.
Why to photograph walls before drywall goes up
Once drywall goes up, nobody can see the drain line behind the vanity or the cable above the TV spot without cutting a hole. This is the only time you can see all of it at once. Years from now, these files can tell you what's behind a wall before you drill, fix a leak or plan an addition.
The chance is easy to miss. One inspection company's pre-drywall guide puts the gap at about three to seven days after rough-in sign-off, and says the insulator's schedule usually sets it. Your builder may have a different timeline, so ask for the rough-in inspection date early, in writing. Building departments set the order of inspections, and it varies by city and county. Nothing should be covered before the required inspections pass.

Pre-drywall photos: what to capture, room by room
Get permission from your builder or contractor first. It's a work site, so wear closed shoes and follow any safety rules they give you. Then capture these in order:
| Target | Why you'll want it later |
|---|---|
| Every wall, corner to corner | Shows studs, pipes and wires for hanging shelves and TVs |
| Ceilings and floor framing | Shows duct runs and drain lines before they're hidden |
| Blocking behind future TVs, grab bars, cabinets and heavy shelves | Tells you where solid wood is, or proves it was left out |
| Kitchen and bathroom plumbing walls | Where leaks are most likely to be traced later |
| Junction boxes and panel area | Helps an electrician trace a circuit |
| Shower pans and any test markings | Backs up a warranty conversation if a leak shows up |
| Exterior vents and where they exit | Shows the dryer, bath and kitchen exhaust routes |
Keep a tape measure in the frame, starting from a fixed point like a door frame or room corner. A Hacker News commenter pointed out that regular stud spacing gives you a built-in scale, though you shouldn't assume every stud follows it.
Two capture methods have worked for owners. One tagged every photo's filename to its location on the blueprints, so finding a detail meant reading the plan and opening that file. Another used a 360-degree camera, where one shot replaced about 5 to 15 photos and about 3,000 square feet took about 15 minutes. A third owner found a phone scanning app wouldn't stitch rooms without walls, so a plain video of every room did the job. Video is the safe default.
Know the limits. Photos are a record, not an inspection. For a new build, you can also hire an independent pre-drywall inspection. One company reports 3 to 5 hours on site for a 2,000 to 3,500 square foot home, and common finds include missing nail plates, sagging drain runs and missing fire-blocking. Old photos also go out of date if anyone reworks a wall, so use a stud finder before drilling and call a licensed electrician or plumber if you might hit wiring, gas or water lines.

How to photograph walls before drywall, step by step
- Ask for the schedule early
Tell your builder you want to visit after rough-in inspections and before insulation. Ask for the expected date and how much notice you'll get.
- Confirm inspections have passed
The rough-in work needs to be approved first, or your photos may show work that later changes. Your building department decides the order.
- Pack your gear
Bring a charged phone, a backup battery, a tape measure, painter's tape and a printed floor plan.
- Film each room slowly
Walk the room clockwise, saying the room name out loud at the start. Hold a tape measure in view on each wall.
- Take wide photos and close-ups
Shoot each wall straight on, then get closer on plumbing, junction boxes, blocking and anything unusual. Don't forget the ceilings.
- Name files that day
Use names like kitchen-north-wall-01 and mark the matching wall on your floor plan, while you still remember.
- Back up and store
Save a copy in cloud storage and another in your home records folder. Pass the files to the next owner when you sell.

How pre-drywall photos help with kids and pets
Leave children and pets at home for this visit. Open framing and floors, nails and loose materials make a job site a bad place for them.
The photos pay off for family safety later. CPSC recommends anchoring TVs and furniture with drawers, doors or shelves to the wall. Knowing where the studs and any blocking sit makes that easier in nurseries and kids' rooms. If you plan baby gates at stairs or a pet door, ask the builder about extra blocking while the walls are open, then photograph it.
Photos before drywall and pre-drywall inspection questions
When is the best time to take photos before drywall?
After the plumbing, electrical and HVAC rough-in work is finished and inspected, and before insulation goes in. Ask your builder for the date, because the gap can be just a few days.
Can my builder refuse to let me on site?
It depends on your contract and the builder's site rules, so read the contract and ask early. If you can't go yourself, ask whether the site supervisor can take you on a short guided visit or send photos.
Do photos replace a pre-drywall inspection?
No. Photos record what's there, while an inspector looks for defects like missing nail plates or poor drain slope. Those are generally cheaper to fix before the walls close.
