The Ultimate New Construction Walkthrough Checklist (2026 Edition)

New Construction Walkthrough Checklist

In 2026, the “Pre-Possession Walkthrough” (also known as a Pre-Delivery Inspection or PDI) is your most important defense against post-move-in headaches. This isn’t just a tour; it is a formal inspection where you and your builder document every scratch, dent, and mechanical hiccup.

Once you sign off and move your furniture in, proving that a scratch on the hardwood was the builder’s fault—and not your movers’—becomes nearly impossible. Use this 2026 checklist to ensure your “brand new” home is actually perfect.

1. The Walkthrough Toolkit

Don’t show up empty-handed. In 2026, technology is your best friend:

  • High-Output Flashlight: Even in a bright house, you need to see into dark corners and under sinks.
  • Phone Charger: The easiest way to test if every electrical outlet is live.
  • Blue Painter’s Tape: Use small strips to “flag” cosmetic defects (paint drips, drywall nicks) so the trades know exactly where to touch up.
  • Measuring Tape: Confirm your fridge or sofa will actually fit the final dimensions.
  • Thermal Camera (Optional but Recommended): Many 2026 buyers use a phone-attachable thermal camera to check for cold spots in insulation or “hot” electrical breakers.

2. Interior Systems & Finishes

Electrical & Plumbing

  • [ ] Test Every Outlet: Plug your charger into every single socket.
  • [ ] The “Flood” Test: Fill every sink and tub to the brim, then release them all at once. Check the pipes underneath for leaks under pressure.
  • [ ] Flush Everything: Flush every toilet multiple times to ensure they seal correctly.
  • [ ] GFCI Check: Test the “Reset” buttons on outlets near water sources (Kitchen/Baths).

Kitchen & Appliances

  • [ ] Appliances: Run a short cycle on the dishwasher. Turn on every burner. Ensure the fridge water dispenser works.
  • [ ] Cabinetry: Open and close every drawer. Check for “soft-close” functionality if you paid for that upgrade.
  • [ ] Countertops: Shine your flashlight across the surface to catch hidden scratches or chips in the stone/quartz.

Walls, Floors & Trim

  • [ ] The “Squeak” Walk: Walk every square foot of the floor. Listen for subfloor squeaks that need to be screwed down before the warranty expires.
  • [ ] Baseboards & Transitions: Ensure there are no gaps between the flooring and the trim.
  • [ ] Window Seals: Open, lock, and close every window. Check for “fogging” between panes, which indicates a broken seal.

3. Exterior & Mechanicals

Grading & Drainage (Vital for Alberta)

  • [ ] The Slope: Ensure the soil slopes away from the foundation on all sides.
  • [ ] Downspouts: Confirm they are attached and directing water at least 6 feet away from the home.
  • [ ] Window Wells: Ensure they are clear of construction debris and have proper gravel drainage.

HVAC & Garage

  • [ ] Thermostat: Cycle the heat and the A/C (weather permitting) to ensure the furnace kicks in.
  • [ ] Filter Check: Ask the builder to show you exactly where the furnace filter is and how to change it.
  • [ ] Garage Door: Test the safety sensors (the “electric eyes”) to ensure the door reverses if something is in the way.

The “1-2-5-10” Warranty Reality

In Alberta, your walkthrough is the baseline for your New Home Warranty.

  • 1 Year: Workmanship and materials (This is where your walkthrough items live!)
  • 2 Years: Delivery and distribution systems (HVAC, Plumbing, Electrical).
  • 5 Years: Building Envelope (The shell of the home).
  • 10 Years: Major Structural components.

How long should the walkthrough take?

Never rush this. A thorough walkthrough for a standard detached home should take 1.5 to 2.5 hours. If your builder is pushing you to finish in 30 minutes, stand your ground.

Can I bring my own home inspector?

For 2026, Edmonton council approved a u003cstrongu003e6.9% property tax increaseu003c/strongu003e. However, if your lot is classified as u0022derelictu0022 (if there’s a crumbling structure on it), you could face a significantly higher tax rate. Once the lot is truly vacant and ready for development, it is taxed at the standard residential rate.

What if an item isn’t fixed by move-in day?

This is common. Ensure the item is on the “Punch List” or “Deficiency Report” signed by both you and the builder. Most purchase agreements allow the builder a reasonable time (usually 30 days) to complete minor repairs after possession.

Should I test the A/C in the winter?

No. Do not turn on your air conditioner if the outside temperature is below 15°C, as it can damage the compressor. Most builders will provide a “seasonal warranty” to test the A/C once the weather warms up.

What is the most common missed item?

The Attic. Buyers rarely look up there. Ensure the insulation is level and that the bathroom fans are actually vented out the roof, not just blowing into the attic space.
