Deck Building Cost in Winnipeg (2026)

Yes, the City of Winnipeg requires a building permit for any deck that is more than 2 feet (600 mm) above ground level or if it will eventually support a roof or sunroom. Permit fees typically range from $150 to $300 depending on the project value.

For a standard pressure-treated brown wood deck, Winnipeg homeowners can expect to pay between $32 and $50 per square foot, including labor and materials. A standard 192 sq ft deck typically starts around $6,300 to $7,800.

Composite decking costs significantly more upfront—typically $65 to $85 per square foot installed—but it withstands Winnipeg's extreme temperature swings and freeze-thaw cycles much better than wood, requiring zero staining and lasting 25+ years.

While not always legally required for low-level freestanding decks, screw piles are highly recommended in Winnipeg due to the region's expansive clay soil and deep frost line. Adding screw piles typically costs $200 to $300 per pile.
