Deck & Gazebo in Toronto — 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 Toronto, 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 Toronto backyard is set by grade, lot width and what the house can carry. Toronto homes run from 1890s brick semis with balloon framing and knob-and-tube remnants, through 1920s detached homes on 25-foot lots, to 1950s bungalows further out. Basements are frequently shallow, floors are rarely level, and joists are often undersized by modern standards. We survey structure, panel capacity and drain material before quoting rather than after demolition.
Narrow lots, laneway access and shared driveways mean material staging and dust control matter more here than anywhere else in the region. We plan delivery windows and street occupation before the first truck arrives.
Permits — Toronto Building
Toronto permits second suites as-of-right in most residential zones under Bill 23, but restricts new entrances on the front façade that make a house read as a duplex — side and rear entrances are usually the workable route. Heritage Conservation Districts and ravine protection add review steps that we check before design.
