Calgary Flood-Risk Due Diligence for Home Buyers

Start with the official City flood map

The City of Calgary publishes a Regulatory Flood Map through its open-data service. Review the exact location and read the dataset context and limitations. Boundaries, regulations and mitigation can change, so save the date and source of your review.

Investigate the specific property

Ask appropriate questions about known water entry, repairs, insurance claims, floodproofing and permits. Inspect grading, drainage, sump systems, backwater protection and visible moisture indicators within the professional’s scope. Obtain specialist advice where uncertainty remains.

Confirm insurance before condition removal

Availability, limits, deductibles and exclusions can vary by insurer and address. Provide accurate property information and request written confirmation that the intended coverage is available and affordable before the contractual deadline.

• Overland-water and sewer-backup coverage details.
• Deductibles, limits and exclusions.
• Prior claims or known events disclosed through proper channels.
• Lender insurance requirements.

Compare risk with price and future marketability

A buyer may accept a known risk if mitigation, insurance, price and lifestyle fit are satisfactory. The decision should be documented, not assumed away. Consider whether future buyers and lenders will have the same questions when the property is eventually resold.
