The Contract Is Your Protection
A renovation contract isn’t just a formality — it’s the document that protects you if things go wrong, defines what “done” means, and sets expectations for both sides. Here’s what every Calgary homeowner’s renovation contract should include.
Must-Have Contract Elements
1. Detailed Scope of Work
Not “kitchen renovation” — it should list every major element: specific cabinet manufacturer and model, countertop material and thickness, tile brand and code, fixture model numbers, electrical scope, plumbing scope, what is excluded.
2. Contract Price and Allowances
Fixed price (better for homeowner) or cost-plus with a cap. If there are “allowances” (e.g., “$3,000 tile allowance”), understand that going over the allowance is a change order — it costs you more.
3. Payment Schedule
Tied to milestones, not to calendar dates. Example:
- 10% on signing
- 25% on demo completion
- 25% on rough-in inspections passed
- 25% on drywall and flooring complete
- 15% on substantial completion
Never pay more than the work completed to date.
4. Start and Completion Dates
With a penalty clause for late completion (or at minimum an agreed process for delays and communication).
5. Change Order Process
All changes to scope must be in writing, signed by both parties, before work begins. Change orders that aren’t in writing are the source of most renovation disputes in Calgary.
6. Permit Responsibility
Clearly state that the contractor is responsible for pulling all required permits and scheduling all inspections.
7. Warranty
Minimum one year on labour for most projects. Alberta’s New Home Buyer Protection Act covers new builds (1 year labour, 2 years mechanical, 5 years building envelope, 10 years structural). For renovations, negotiate in writing.
8. Lien Waiver Clause
Protect yourself from subcontractors and suppliers placing liens on your property if the GC doesn’t pay them. Request statutory declarations from the GC confirming all subs and suppliers are paid at each payment milestone.
9. Insurance Requirements
State the minimum liability insurance ($2M) and WCB coverage required, and that certificates must be provided before work starts.
10. Dispute Resolution
How will disputes be handled? Mediation first (cheaper than court). Which jurisdiction? Alberta law.
Red Flag Contract Clauses
- “All payments non-refundable” — walk away
- No warranty language at all
- Payment schedule requiring 50%+ upfront
- Contractor can change the price without your written approval
- No completion date
Get a Lawyer to Review Large Contracts
For renovations over $100,000, spend $500–$1,500 on a construction lawyer review. It’s cheap insurance on a six-figure investment.
