Hidden Renovation Costs in Vancouver: What to Budget for Surprises
Hidden Costs in Vancouver Renovations
The average Vancouver renovation comes in 15–25% over initial budget — not because of contractor dishonesty, but because of hidden conditions, missed items, and scope additions. This guide covers the most common hidden costs.
Top Hidden Costs by Renovation Type

The 15% Rule
Build a minimum 15% contingency into your renovation budget. For pre-1960 homes, use 20–25%. The contingency is not for choosing upgrades — it’s for genuine surprises. If it’s not needed, keep it for future maintenance.
