Deck & Gazebo in North York — the short answer
Deck and gazebo construction covers the design, permitting and building of raised or grade-level outdoor structures — including footings below the frost line, pressure-treated framing, and pressure-treated, cedar, composite or PVC decking. In the GTA in 2026, professionally built decks cost roughly $30 to $50 per square foot in pressure-treated lumber, $50 to $75 in cedar, $65 to $90 in composite, and $80 to $110 in PVC. In North York, deck permits are issued by Toronto Building, and a permit is generally required once a deck is attached to the house or sits more than 600 mm above grade.
What we can build in a North York backyard is set by grade, lot width and what the house can carry. The older stock is post-war brick bungalow and split-level with deep lots that support walk-out grading. The newer stock is 3,000 to 5,000 square foot rebuilds from the 2000s onward, where the renovation question is almost always finish quality rather than structure. Willowdale in particular has been rebuilding lot by lot for two decades.
Lot grading in North York frequently drops toward the rear, which is the ideal condition for a walk-out basement suite. We check grade elevations at the feasibility stage because it can change a project's economics entirely.
Permits — Toronto Building
Second suites are permitted as-of-right in most North York residential zones. Deep lots here often allow a rear walk-out rather than an excavated side entrance, which is both cheaper and produces a far better unit with real daylight.
