Deck & Gazebo in Vaughan — 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 Vaughan, deck permits are issued by City of Vaughan Building Standards, 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 Vaughan backyard is set by grade, lot width and what the house can carry. Predominantly 1995 onward: 2,500 to 5,000 square foot detached homes in Maple, Kleinburg, Patterson and Vellore Village, with poured foundations, tall basements, 200 amp services and cold cellars. Thornhill holds older 1970s and 80s stock where layouts benefit from opening up.
Large lots support serious outdoor builds — multi-level composite decks, gazebos, outdoor kitchens and privacy screening — which is a growing share of our Vaughan work.
Permits — City of Vaughan Building Standards
Vaughan permits additional residential units subject to Building Standards approval and registration. Tall basement ceilings mean height is almost never the constraint — the design question is where a separate entrance can go without conflicting with the side-yard setback.
