Fixed price or cost plus for a Vancouver renovation?

For most Vancouver homeowners, a fixed-price contract offers more budget certainty — but cost-plus can be the smarter choice for complex renovations where the scope isn't fully defined upfront.

The right contract structure depends heavily on what you're building, how well the project is scoped, and how much risk you're willing to carry. Both models are widely used in Metro Vancouver, and understanding the trade-offs will save you from nasty surprises mid-project.

Fixed-price contracts work best when the scope is crystal clear — a kitchen renovation with finalized drawings, specified materials, and no unknowns behind the walls. You agree on a number, the contractor carries the risk of overruns, and your budget is protected. The catch: contractors price that risk into their bid, typically adding 10-20% contingency to cover unknowns. In Vancouver's market, where labour and materials are already 15-25% above the national average, that buffer can add tens of thousands to a quote. You're also more likely to face change order disputes if anything shifts mid-project — and in older Vancouver homes (think Vancouver Specials, pre-1950 character homes in Kitsilano or East Van), something almost always shifts.

Cost-plus contracts — where you pay actual costs plus an agreed contractor fee (typically 10-20% of costs, or a fixed management fee) — are better suited for gut renovations, heritage properties, or any project where you're opening walls and genuinely don't know what you'll find. They're also common for high-end custom work where the homeowner wants flexibility to make changes without triggering formal change orders. The transparency is real: you see invoices, receipts, and labour hours. The downside is that your final cost is unknown until the end, which makes financing harder and requires more active involvement from you.

Vancouver-specific factors push many experienced renovators toward cost-plus for anything beyond cosmetic work. Older homes here frequently reveal asbestos (common in pre-1990 textured ceilings and floor tiles), knob-and-tube wiring, undersized electrical panels, or drainage issues once walls open up. Remediation costs are real — asbestos abatement alone runs $2,000-$8,000+ depending on scope, and that's before the actual renovation resumes. A fixed-price contractor who hasn't priced these risks either builds in a large buffer or walks away from the job when surprises hit.

A hybrid approach is increasingly popular in Metro Vancouver: a fixed price for clearly defined work (framing, drywall, tile) with a transparent cost-plus structure for demolition and rough-in phases where unknowns are highest. This gives you budget certainty where it's achievable and flexibility where it isn't.

Regardless of which model you choose, make sure your contract addresses a few key things: a clear payment schedule tied to milestones (not arbitrary dates), a 10% holdback as required under BC's Builders Lien Act, written change order procedures, and proof of WorkSafeBC coverage and liability insurance from your contractor.

Your next step is to get your project scoped as thoroughly as possible before signing anything. Detailed drawings, a finalized material schedule, and — for older homes — a pre-renovation inspection can dramatically reduce unknowns and make fixed-price bids more competitive and accurate.
