Basement Renovation Specialists in Vancouver
Legal secondary suites, family rooms, gyms, wet bars — every basement reno permitted, inspected, and built to last.
Basement renovations in Vancouver fall into two camps: lifestyle (family room, home gym, theatre, wet bar) and revenue (legal secondary suite generating $1,800–$2,800/month in current Vancouver rental market). Renew Co Contracting builds both, with the same attention to the things basements punish poorly-built work for — moisture management, ceiling height optimization, egress windows, and proper ventilation. Vancouver basements have unique constraints: low ceiling heights (often 6'8″–7'2″ before any work), water table issues in certain neighbourhoods (East Van and parts of Burnaby), and strict City of Vancouver Secondary Suite Bylaw requirements. We know the playbook for every one.

Legal secondary suites — the City of Vancouver playbook
Vancouver's Secondary Suite Bylaw allows most single-family homes to add a legal secondary suite, but the requirements are specific and non-negotiable. To pass final inspection in the City of Vancouver, a legal suite must include:
- Minimum ceiling height of 6'8″ in living areas, 6'4″ under beams and ducts
- Egress windows in every sleeping room (specific size and operable specifications)
- 45-minute fire separation between the suite and the main dwelling
- Interconnected hardwired smoke alarms across both units
- Separate heating zone (or proven adequate ventilation from main system)
- Independent kitchen with full cooking facilities
- Off-street parking provision (varies by neighbourhood)
- Owner-occupied requirement for the primary residence
How much does a basement renovation cost in Vancouver?
A cosmetic basement refresh — already-finished space getting new paint, flooring, and trim — runs $15,000–$35,000. Building a family room or home gym from unfinished basement runs $40,000–$75,000. A legal one-bedroom secondary suite typically costs $75,000–$130,000 including all permits, egress windows, fire separation, and finishing. A two-bedroom legal suite or a premium suite with high-end finishes runs $130,000–$200,000+. The biggest cost drivers are egress window installation (concrete cutting, window well, drainage — typically $4,000–$8,000 per window), separate hydro metering ($2,500–$5,000), and bringing existing electrical service up to code.
Family rooms, home gyms, and lifestyle basements
Not every Vancouver basement renovation is a rental conversion. We build family rooms, home theatres, home gyms with proper sound insulation and ventilation, wine cellars with humidity control, wet bars with full plumbing, and home offices with structured wiring. Lifestyle basements skip the secondary-suite requirements (no egress windows needed unless there's a bedroom, no fire separation, no kitchen) so they cost less and take less time — typically $40,000–$75,000 and 6–10 weeks.
Moisture management — the basement-specific problem
Vancouver basements deal with more moisture than most Canadian markets because of our climate (60+ inches of annual rainfall) and our older housing stock (many homes built before modern drainage standards). Before finishing any basement, we inspect for moisture intrusion, recommend perimeter drain repairs if needed, install proper vapour barriers, frame walls off the concrete on treated bottom plates, and use moisture-resistant insulation systems. We will not finish a basement that has active moisture issues — fixing the water source first is non-negotiable. This is the most common reason poorly-built basement renovations fail.
How long does a basement renovation take?
A cosmetic refresh takes 2–4 weeks. An unfinished basement converted to lifestyle space takes 6–10 weeks. A legal secondary suite takes 10–16 weeks for a one-bedroom, 12–20 weeks for a two-bedroom or premium build. The City of Vancouver secondary-suite permit timeline currently runs 6–10 weeks before construction even starts, so allow that lead time when planning. We submit complete drawings on the first try, which avoids the back-and-forth that typically extends permit timelines.
Why basements need a specialist
Basement renovations look simple — it's a box, finish it — but they have more failure modes than any other renovation. Common contractor mistakes we see in repair projects:
- Vapour barriers on the wrong side of the insulation, trapping moisture
- Insulation in contact with concrete, sucking up groundwater capillary
- Drywall touching the floor, wicking up moisture during a leak
- Egress windows installed without proper drainage, flooding the basement during heavy rain
- Drop ceilings hiding active leaks that are rotting joists above
- Wood framing in direct contact with concrete (not treated lumber)
- Bathroom fans venting into the joist cavity instead of exterior

A legal one-bedroom secondary suite in Vancouver typically rents for $1,800–$2,400 per month in current 2026 market conditions, varying by neighbourhood. A two-bedroom suite rents for $2,400–$3,200. Most legal suites pay back their full construction cost within 4–6 years.
How do you handle basement moisture issues?
Before finishing any basement, Renew Co inspects for moisture intrusion and recommends perimeter drain repairs if needed. We install proper vapour barriers, frame walls off the concrete on treated bottom plates, and use moisture-resistant insulation systems. We will not finish a basement that has active moisture issues until the water source is fixed.
What is the minimum ceiling height for a basement renovation?
City of Vancouver code requires 6'8″ minimum ceiling height in living areas of legal secondary suites, and 6'4″ under beams and ducts. For non-suite basements (family rooms, home gyms), 6'4″ is typically acceptable. Renew Co measures your basement before quoting to confirm the build is code-compliant.
