Common Questions

Yes, in Kitchener, a permit is required if the deck is attached to the house or if it is more than 24 inches (2 feet) above the ground at any point. Ground-level detached decks under 10 square metres (approx. 108 sq ft) typically do not require one.

The base permit fee for a residential deck in Kitchener is $95.00. However, homeowners must also account for a road damage deposit of $142.32 per metre of frontage, which is refundable upon successful final inspection.

A standard 200 sq ft deck built with pressure-treated wood typically costs between $8,000 and $12,000. If using mid-range composite materials like Trex or Fiberon, the price increases to between $14,000 and $22,000.

Pressure-treated wood is the most affordable at $35–$55 per sq ft installed. Composite decking ranges from $55 to over $100 per sq ft but is often preferred in Kitchener's freeze-thaw climate because it requires no staining and lasts 25+ years.
