Basement Renovations in Vancouver
Kyrax Developments renovates and finishes basements across Vancouver, Burnaby, and the North Shore — from a recreation room and home office to a fully legal secondary suite. As a licensed contractor already running multi-family and legal-suite work across BC, we bring the same code discipline to a basement as we do to a 50-unit building.
Basement finishing, done to code.
Moisture & drainage assessment
Before any framing goes in, we assess existing moisture, grading, and drainage — the single biggest risk factor in an older Vancouver basement.
Framing & insulation
Wall and ceiling framing, vapour barrier, and insulation values for below-grade space that meet the Vancouver Building By-law, or the BC Building Code outside the city.
Egress windows
Enlarging or adding egress windows where a bedroom is planned — a code requirement for any legal sleeping room below grade.
Electrical & plumbing
Panel capacity review, new circuits, and plumbing rough-in for a bathroom, wet bar, or secondary suite kitchen.
Legal secondary suite conversion
Separate entrance, fire separation, sound attenuation, and permit sign-off for a fully legal secondary suite, where that's the goal.
Finishing
Flooring, drywall, trim, and paint suited to a below-grade environment, plus final inspection and handover.
From assessment to finished space.
Moisture & scope assessment
We check for existing moisture, drainage issues, and ceiling height before confirming what the space can become.
Design & permit
Layout confirmed and, for a legal suite, a full secondary suite permit application submitted to the City of Vancouver.
Framing & rough-ins
Egress windows, framing, electrical, and plumbing installed and inspected before insulation and drywall close the walls.
Insulation & drywall
Vapour barrier, insulation, and drywall installed to below-grade code requirements, with fire separation where a suite is involved.
Finishing & occupancy
Flooring, trim, and paint completed, final inspections passed, and — for a secondary suite — occupancy sign-off secured.
What makes a basement renovation different.
Below-grade moisture is the most common reason a basement renovation fails early. We assess exterior grading, weeping tile condition, and existing dampness before any framing goes in — not after.
In the City of Vancouver both rules come from the Vancouver Building By-law, not the BC Building Code. Bedrooms and living spaces need a 2.1 m ceiling over a set minimum area (4.9 m² in a main bedroom) and 2.0 m of clear height under beams and ducts, and every bedroom in an unsprinklered suite needs an egress window. When a suite is added to a house built under a permit issued before June 22, 2004, the by-law accepts existing headroom of 1,950 mm over 80% of the suite area and all egress routes and 1,850 mm over the rest, with 2,000 mm in exits; a house permitted on or after that date must meet the full rule. That allowance is Vancouver's own: the BC Building Code's version, which governs Burnaby and the North Shore, works room by room, so it does not settle a Vancouver case. Older Vancouver and Burnaby homes often need a window enlarged or a window well added to comply.

If the goal is a legal secondary suite, the City of Vancouver requires a separate permit covering fire separation, a second means of egress, parking (in some zones), and a dedicated electrical panel or sub-panel. This is a materially different scope than a recreation-room finish, and we quote it separately.
Whether it's a media room under a busy living area or a suite above a rental unit, sound attenuation between floors is worth planning for at framing stage — it's far cheaper to add now than to retrofit later.
Bathroom additions inside a basement renovation follow the same code and waterproofing standards covered on our bathroom renovations pages.
A recreation room and a legal suite don't price the same.
We don't publish flat prices for basement renovations in Vancouver because the scope difference between a simple finish and a legal suite conversion is significant. These are the variables that matter.
Legal suite vs. recreation room
A fully legal secondary suite carries permit, egress, fire-separation, and panel-upgrade requirements a simple finish doesn't.
Existing moisture & drainage
A dry, well-drained basement is a much simpler starting point than one needing exterior waterproofing or a sump pump added.
Egress window work
Enlarging a window opening or excavating a new window well adds structural and excavation cost where a bedroom is planned.
Panel capacity
Older homes sometimes need an electrical panel upgrade or a dedicated sub-panel to support a kitchen or full suite.
Ceiling height
Basements below the minimum ceiling height sometimes require underpinning or slab lowering — a significant cost driver where it applies.
Permit & inspection scope
A secondary suite permit involves considerably more municipal review than a straightforward recreation-room finishing permit.
Answers before you ask.
In many cases, yes, subject to zoning. The City of Vancouver allows one secondary suite per single-family home, requires a permit to add or legalize one, and treats a suite as legal only once it has passed final inspection. The review covers egress, fire separation and electrical capacity, which is what we assess at the initial walkthrough. Source: City of Vancouver, Create or legalize a secondary suite, verified September 2026. The zoning and permit conditions are set out in our answer on legal secondary suites.
Yes, in almost every case. The City of Vancouver requires a permit for renovations that move interior walls or existing plumbing, electrical or gas lines, for structural repairs, and for adding a secondary suite; only replacing fixtures, cabinets or flooring, painting and minor repairs are exempt. The City's penalty for work started without a required permit is typically double the permit fee. Source: City of Vancouver, When you need a permit, verified September 2026. The exemptions and penalties are listed in our answer on basement permits.
We assess exterior drainage and existing dampness before framing starts, and address the source — grading, weeping tile, or a sump pump — rather than finishing over a moisture problem.
An egress window is a bedroom's emergency exit. In the City of Vancouver the rule is Article 9.9.10.1 of the Vancouver Building By-law, which the City adopts under the Vancouver Charter in place of the BC Building Code. Unless the suite is sprinklered, every bedroom needs an outside window or exterior door that opens from inside without keys or tools, with an unobstructed opening of at least 0.35 m² and no dimension under 380 mm, plus 760 mm of clearance in front of it where it opens into a window well. The BC Building Code, which applies in Burnaby, North Vancouver and West Vancouver, has the same article with the same figures. If your basement bedroom has no such window we can usually enlarge an existing opening or add a window well.

The provincial version is set out in our answer on egress window sizing.
On our projects, a recreation-room finish runs 6 to 10 weeks. A full legal secondary suite conversion, including permit review, usually runs 3 to 5 months from application to occupancy.
Yes — this page covers Vancouver, Burnaby, North Vancouver, and West Vancouver. For Surrey or Langley, our team runs the same basement scope under our broader renovations service.
