Deck builders in Toronto are really in the footing business: a deck is only as good as what’s under it. Ours bear on footings poured below the 4-foot frost line, framed to the Ontario Building Code span tables, with the permit drawings and inspections handled for you, because an unpermitted deck becomes your problem the day you sell the house.
Anything over 24 inches off grade, most walkout and back-door decks, needs a Toronto building permit. We do the drawings, file the application, and meet the inspector at footing and framing stages. You get a deck with paper, which matters at resale and with insurance.
Toronto’s housing stock decides a lot: ledger attachment into brick veneer on a 1950s bungalow is done differently than into a modern frame wall, and walkout basements change the railing math entirely. We’ve built on all of it. Decks pair naturally with fence and privacy screening, same posts, same visit, better price together.
Pressure-treated decks run roughly $45 to $65 per square foot built; cedar $60 to $85; composite $75 to $110+. A typical 12 x 16 PT deck with stairs and railing lands between $9,000 and $14,000 including permit drawings.
Decks more than 24 inches above grade need a building permit in Toronto, and attached decks usually do regardless. We produce the drawings, submit the application, and schedule the inspections. It is built into the quote, not an extra.
PT is the budget workhorse and takes stain well after a season. Cedar looks and smells the part but wants maintenance every two to three years. Composite costs the most up front and the least every year after. We bring samples; most families with kids and a hose pick composite.
Once the permit is issued, most decks are built in 4 to 8 working days including footings. Permit timelines in Toronto run a few weeks, so start the process in late winter and the deck is ready for May.
