You’ve decided to add a secondary suite to your Vancouver, Burnaby, or North Shore home. Somewhere in that process, you’ll run into the rule that a secondary suite needs its own separate entrance. It’s not a suggestion or a local preference—it’s a BC Building Code requirement. Here’s what the rule actually says, why it exists, and exactly what a building inspector checks for on site.
The Rule in Plain Language
Every dwelling unit—including a secondary suite—must have an independent way to exit to open air without passing through another unit. That’s the core of the requirement. In practice, it means your secondary suite needs its own direct access to the outside, separate from the main house’s entrance, and residents of the suite must be able to get in and out without walking through the primary residence.
Why This Rule Exists
The requirement is tied to egress—safe exit in an emergency—life safety, and legal occupancy. If there’s a fire or other emergency in the primary residence, occupants of the secondary suite need a way out that doesn’t require passing through it, and vice versa. This isn’t a suggestion. Without a compliant entry, your secondary suite may not be permitted, insurable, or legally rentable. Many homeowners discover this late in their renovation planning and face costly design changes as a result.
What Counts as a Separate Entry
A separate entry means the suite must have its own direct access to the outside—typically a door that opens to grade level, a deck, stairs, or a laneway. It cannot share the primary entrance with the main house, and it cannot require residents to pass through the primary suite to exit the building. In practice, this means:
- A side or rear door leading directly outside, or
- An exterior staircase to an upper-level entry, or
- A ground-level walkout from a basement or garden-level secondary suite
The entry must be weather-protected and accessible year-round. A door that opens onto a narrow alley or leads across the primary homeowner’s yard still counts, provided it’s a direct, outside path. A door that opens into a shared foyer, hallway, or laundry room inside the primary residence does not count, no matter how convenient it seems.
What Inspectors Actually Check
When a building inspector reviews a secondary suite entry, they’re checking specific, measurable things—not just “is there a door here”:
- Door swing and width: the door must meet minimum width standards and swing outward in the direction of travel—a door that opens into a closet or a dead-end alcove fails inspection
- Landing dimensions: the platform outside the door must be large enough to stand on safely and meet code-minimum size
- Stairs, guards, and handrails: if the entry involves steps, handrail height, guard height, and step dimensions all have to meet code, along with snow load standards where relevant
- Fire-rated separation: the wall and door assembly separating the secondary suite from the primary home must meet fire-rating requirements—this affects materials, not just layout
- Lighting: exterior entry areas need adequate lighting, which is a code requirement, not an optional finish
- Drainage and weatherproofing: water must be directed away from the door and foundation—pooling water or ice at the entry is a safety and inspection red flag
How This Plays Out on Real Vancouver and North Shore Lots
The secondary suite entry requirement forces real decisions early in your design process. Unlike a renovation that only affects interior walls or finishes, adding a secondary suite entry may require reconfiguring your exterior wall and foundation, building new stairs or a landing, extending utilities (water, sewer, electrical) to serve a new entry point, creating setback distances from property lines or neighbouring structures, and ensuring the entry path doesn’t conflict with driveways, fences, or easements.
On a Vancouver property lot with tight boundaries or a North Shore home built on a steep slope, creating that separate entry can eat into your usable square footage or require expensive site work.
Municipal Bylaws Add to (Not Replace) the Code
The BC Building Code sets the minimum egress standard everywhere, but each municipality—Vancouver, Burnaby, and North Shore communities—layers its own bylaws on top, covering things like setbacks, parking, and where an entry is allowed to face. Some are more permissive than others about how that entry can be configured. What’s permitted in one Vancouver neighbourhood may not be in another, and Burnaby’s requirements differ from the North Shore’s.

Budget and Timeline, Briefly
Meeting the code requirement isn’t free: a simple side-yard door with a small landing might add a few thousand dollars to your renovation, while an upper-level entry requiring a full exterior staircase and waterproofing can run well into five figures. It also affects your timeline, since the entry must be shown in your permit drawings and verified by inspection before occupancy.

Our Approach to Secondary Suite Entries
Our team works with homeowners in Vancouver, Burnaby, and North Shore communities to integrate the secondary suite entry into the overall renovation design from day one. We coordinate with local code officials early, ensure the entry meets both safety and practical standards, and plan it to minimize disruption to your existing home layout and site.
Start by confirming your municipality’s specific rules, then work backwards to design a layout and addition that makes a code-compliant separate entry feasible, safe, and affordable.
