You’ve decided to add a secondary suite to your Burnaby or North Shore home, or perhaps you’re planning a house addition in Vancouver. Once you know a separate entrance is required, the next question is practical: what actually happens between deciding to build one and getting the green light to rent it out? Here’s the process, step by step.
Step 1 — Confirm Your Property Is Eligible
Before any drawings happen, confirm the basics with your local building or planning department:
- Zoning compliance—your lot size, setbacks, and current zoning category must allow a secondary suite
- Parking requirements—some municipalities require additional parking for a secondary suite, while others have reduced or waived requirements
- Lot coverage limits—adding square footage or altering the footprint may affect how much of your lot can be built on
- Strata restrictions—if you own a condo, your strata bylaws may prohibit secondary suites entirely
- Rental licensing—some cities require a separate business license for rental suites
Bring a property survey if you have one; it helps the planner assess setbacks and lot coverage immediately. This step alone can save weeks later—a design built around an ineligible property has to be redone from scratch.
Step 2 — Design the Entry to Meet Code
With eligibility confirmed, the entry gets designed against BC Building Code egress rules and your municipality’s site requirements:
Location and site work: The entrance location depends on your lot layout, existing landscaping, utility lines, and setback requirements. Side or rear entries often work better on smaller urban lots. You may need retaining walls, ramps, or deck work to make the entrance accessible and functional year-round.
Weatherproofing: BC’s wet climate means proper drainage around any new entry is critical. Covered stoops or awnings, sloped walkways, and guttering keep water away from the foundation and door frame.
Electrical and mechanical access: Secondary suites need independent electrical service (often requiring an electrical panel upgrade) and separate metering in some municipalities.
Fire-rated construction: Walls separating a secondary suite from the primary home must meet fire-rating requirements set out in the building code, affecting door frames and wall assembly. For the full explanation of why these rules exist and what inspectors check, see our BC Building Code guide.
Step 3 — Submit Your Permit Application
Your entry design is submitted as part of the secondary suite permit application, and the building department checks it against the code and local bylaws. In our experience, clear, detailed drawings of the entry—including grading, dimensions, landing sizes, and drainage—speed up approval. Vague or incomplete entry designs are the single most common cause of delay we see, because they prompt request-for-information letters that add weeks to the timeline.
Step 4 — Plan Review and Possible Revisions
The building department reviews your application against zoning bylaws and the building code. If anything is unclear or non-compliant—an entry that doesn’t meet setback requirements, a door swing that opens into a dead-end, insufficient landing dimensions—you’ll receive a request for revisions before the permit is issued. A professional site plan and building drawings make the difference between a quick approval and a back-and-forth process that costs time and potentially money.
Step 5 — Construction and Site Inspections
Once your permit is issued, construction proceeds against the approved drawings. Expect site visits by the building inspector during construction to verify the entrance detail, drainage, fire-rating materials, and electrical connections as the work progresses—not just at the very end.
Step 6 — Final Inspection and Occupancy
Before you can occupy or rent the suite, a final inspection confirms the entry, drainage, fire separation, and electrical work all match the approved permit. This is the gate that determines whether your secondary suite is legally occupiable and insurable.
Realistic Timeline
Adding a secondary suite entrance isn’t a fast project. From initial design review to final permit approval, expect 6 to 12 weeks, depending on how quickly your municipality responds and whether revisions are needed. If structural changes are required—moving a wall, adding drainage, or upgrading electrical—construction adds another 4 to 8 weeks on top of that.
Next Steps
Before you invest in design or permits, visit your municipal planning office with your property address. They’ll confirm whether a secondary suite is allowed, what entrance requirements apply, and what other conditions—parking, licensing, strata approval—you need to meet. Once you’ve confirmed secondary suites are permitted, our team can help you develop a compliant entrance design and guide you through the permit process specific to your municipality and property.
