Buying a new construction or pre-sale home in BC is exciting — but it comes with a process that most buyers aren't fully prepared for. Between the pre-completion inspection, deficiency lists, new home warranties, and builder's lien holdbacks, there's a lot happening in the final stretch before you get your keys.
This guide breaks it all down so you know exactly what to expect, what to protect, and what questions to ask before you sign anything.
Before you take possession of your new home, you have the right to conduct a pre-completion inspection (also called a PDI — Pre-Delivery Inspection or pre-possession walkthrough). This is your formal, on-site opportunity to identify deficiencies before you take legal possession.
This inspection is not optional. It is one of the most important steps in the new construction purchase process, and many buyers underutilize it.
What you're looking for:
Who to bring: Bring a thorough friend or family member who notices detail. If you're spending $700,000+ on a home, $500 for an independent home inspector is money well spent.
At your walkthrough, the builder's representative will record all noted deficiencies on a Deficiency List. This document is critical.
Why it matters:
What to do:
If the builder misses something during the walkthrough, it's not necessarily the end of the world — BC's New Home Warranty Program covers many defects even after possession. But a clear, signed Deficiency List is your cleanest legal path to having items remedied quickly.
Under BC's *Builders Lien Act*, when you purchase a new home, your lawyer will typically hold back 10% of the purchase price in trust for 55 days after possession. This holdback period protects you from claims by subcontractors, suppliers, or tradespeople who worked on your home and haven't been paid by the developer.
Here's why this matters for you as a buyer:
Your real estate lawyer handles this automatically as part of the conveyancing process. Make sure you understand this step and confirm it with your lawyer before closing.
Every new home in BC is covered by the mandatory 2-5-10 New Home Warranty under the *Homeowner Protection Act*. This warranty is provided by a third-party warranty provider (Travelers, Aviva, National Home Warranty, etc.) — not the developer.
Coverage breakdown:
When to make a claim:
Important: warranty claims are time-sensitive. Defects must be reported within the applicable warranty period, and there are specific timelines for notification. Don't wait.
Most developers handle warranty items professionally. But if you encounter resistance:
| Milestone | Timeline |
|---|---|
| Pre-completion inspection | Scheduled by developer, usually 1-4 weeks before possession |
| Deficiency repair timeline | Builder must complete before or promptly after possession |
| Builder's Lien holdback | 10% held for 55 days after possession |
| 2-Year warranty starts | Date of possession |
| 5-Year building envelope starts | Date of possession |
| 10-Year structural warranty starts | Date of possession |
| Claim notification | Varies by warranty provider; document defects as they appear |
Do not rush the walkthrough. You are entitled to a thorough inspection. Test every switch, every tap, every appliance, every door and window. Open every cabinet. Check every wall surface under proper lighting.
Do not sign the Deficiency List until you are satisfied it reflects everything you found. Once signed, it defines the boundary of what the developer is obligated to repair.
Know your warranty provider before closing. Contact them directly if items are disputed or if defects appear after you've moved in. You don't need the developer's permission to make a warranty claim.
Buying new construction in BC comes with real protections — but those protections only work if you know how to use them. The inspection process, the Deficiency List, and the New Home Warranty are your three main tools. Understand each one, take the walkthrough seriously, and don't rely on verbal assurances from the developer.
A well-documented walkthrough and a clearly signed Deficiency List is worth more than any conversation you'll have on-site.
