Yes, a building permit is required if the deck surface is higher than 0.6 metres (approx. 2 feet) above grade at any point, or if it is structurally attached to the house. Uncovered decks under 0.6 metres typically do not require a building permit.
In 2026, a standard residential building permit for an uncovered deck is approximately $205.92. If the project also requires a Development Permit, the additional fee is roughly $550.00, bringing the total permit cost to about $755.92.
Due to Calgary's extreme freeze-thaw cycles, footings must typically be between 36 and 60 inches deep to reach below the frost line and prevent structural shifting or 'frost heave'.
Pressure-treated wood is the most affordable at $35–$60 per sq ft installed. Mid-to-premium composite decking ranges from $100–$130 per sq ft installed. While composite has a higher upfront cost, it typically breaks even within 8–12 years due to lower maintenance expenses.
