Pre-Application Consultation
The Hidden Detail Most Buyers Overlook
Buying a property in the Lower Mainland is a massive investment, but many buyers overlook the most critical hidden detail: the permit history. Whether you're looking for a fixer-upper or a potential multiplex (SSMUH) site, knowing what has—and hasn't—been permitted is the difference between a gold mine and a money pit.
Step 1: Use the City's Public Permit Portal
The City of Vancouver maintains a public-facing database where you can search by address.
- Go to the Vancouver Permit Search Portal.
- Search by Address: Enter the exact street address.
- What to look for: Look for Building Permits, Electrical Permits, and Plumbing Permits.
- Red Flag: If the real estate listing says Newly Renovated Basement but there are no plumbing or building permits listed in the last 5 years, those renovations are likely unpermitted.

1. Identify Unpermitted Work Before Buying
Houses built or renovated in the 1980s, 90s, and 2000s often contain unpermitted secondary suites, unauthorized basement expansions, or structural alterations. If a previous owner finished a basement without a permit, the municipality does not care that you didn't do the work—you inherit the legal liability upon closing.
2. Verify Zoning & Setback Constraints
A pre-purchase permit audit checks the current municipal zoning matrix against the physical lot. We confirm:
- Max Lot Coverage & FSR: Ensures you can build the addition or garage you're planning.
- Environmental & Riparian Setbacks: Flags protected streams, steep slopes, or tree protection zones that restrict building footprints.
- Heritage & Design Guidelines: Identifies special municipal overlay zones (such as First Shaughnessy in Vancouver or heritage conservation areas in New Westminster).
3. Check Regional Building Permit Hub Data
For properties outside of Vancouver (Burnaby, Coquitlam, etc.), the Province has streamlined the process through the BC Building Permit Hub. This tool allows you to check local requirements and Step Code targets for specific addresses, which is vital if you plan on building an addition or a laneway house.

Why Data Isn't the Same as Certainty
Finding a permit on a website is easy. Understanding the implications of that data is where most buyers get stuck. As a Permit Consultant and CTech, I often see three major issues that a basic search won't tell you:
-
The Open Permit Trap: A permit might show as Issued but never Finalled. This can prevent you from getting home insurance or a mortgage until a professional resolves the file with the City.
-
Easements and Rights of Way: A permit search won't show you the underground utility easement that prevents you from building that 1000 sq ft addition you're planning.
-
As-Built Discrepancies: Old paper plans at City Hall are notoriously inaccurate. We use iGUIDE 3D scanning to verify if the official record matches the actual structure.

FAQ: Search Permits Before You Buy
How far back does the Vancouver permit search go?
The online portal typically shows permits from the last 10-15 years. Older permits may require an in-person records request at City Hall.
What if I find unpermitted work on a property I'm buying?
Unpermitted work can affect insurance, financing, and future renovations. A permit consultant can help you assess the risk and potentially legalize the work before closing.
Can I do a permit search for properties outside Vancouver?
Yes. Most Lower Mainland municipalities have online permit portals, and the BC Building Permit Hub provides a centralized starting point for provincial requirements.
