About Basement Renovation in Coquitlam
Metro Vancouver basement renovations — from finishing an unfinished space to a fully legal secondary suite with separate entrance, full kitchen, and ensuite. We pull permits, handle fire-separation and egress requirements, coordinate the inspection schedule, and deliver a code-compliant, rentable space.
Every basement project includes a written scope, fixed-price contract, BC Building Code §9.36 (low-rise residential) permit package, fire-separation per §9.10, $5M CGL, WorkSafeBC, and our 3-year workmanship warranty.

| Finishing + bath | 8–12 weeks |
| Legal 1-bed suite | 12–18 weeks |
| Legal 2-bed + ensuite | 16–22 weeks |
6. Why Our Floor is $50K and Not $35K
Below $50K in 2026 Vancouver, you're either:
- Skipping permits (puts your home insurance at risk and kills resale value of any rental income)
- Cutting fire separation / egress (illegal as a suite, dangerous to occupants)
- Using uninsured trades
We do permitted, code-legal basements. The $50K floor reflects 2026 BC trade rates + permit cost + minimum code-compliant materials.
