Renovation contingency guide
Contingency protects a plan from uncertainty; it is not permission to skip investigation.
What contingency covers
Typical uncertainties include concealed water damage, unsuitable subfloor, additional tear-off layers, access complications, price changes and small scope corrections. Known work should be priced directly rather than hidden inside contingency.
Match the allowance to risk
| Project condition | Planning approach |
|---|---|
| New, visible and well documented | Use a smaller allowance after confirming quantities. |
| Occupied remodel with some concealed work | Use a moderate allowance and document exclusions. |
| Older building or extensive demolition | Investigate first and preserve a larger reserve. |
Keep it separate
Do not tell every bidder to spend the entire contingency. Compare quotes on the defined scope, then retain the reserve for approved changes.
