Cost to build a deck in 2021

Question for anyone that's gone through something similar recently..

I'll be taking possession of a semi in a few months. The basement has a walkout and will be rented. I want to build a deck walking out from the rear main floor entrance with stairs to the ground level. I'd like the deck To be approx 20ft x 20ft. The main floor exit is approx 10ft off the ground. A picture of the back is attached.

You will need a permit.

Contractor…any decent one can probably quote this over the phone in a couple of minutes.

DIY, use a program like Lowe’s Deck Designer and it will provide the cost of all the material once complete.

Do people actually get permits for this type of thing?

Any idea of how long the turn around time is in Toronto?

If it’s 10 feet off the ground you better get a permit. Any contractor who says you don’t need one is not worthy of the job.
You need to make sure it’s engineered correctly for that size and height.

Are you planning all pressure treated, wood railings? Any stairs?

My best guess is around $12,000-$15,000 for material and another $10000 for labour.

Any idea what permit costs and turnaround time look like?

Permits are usually only $200-$300. No idea on turn around.

I’m just ball parking on the labour as I always DIY.

Decks are part of the Ontario Building Code now, and not getting a permit can be a costly mistake. You'll pay a fine, and in my municipality, they'll make you expose the footings to show they are the proper depth. You can gamble and not get a permit, but if a neighbour calls it in, it'll be 2x expensive to fix.
Walk away from contractor who tells you you don't need a permit.

I'm in Ottawa. We're having a contractor replace our old deck this year with a composite, two level deck. It will be 20 x 25. Cost is $37K all in. I'm removing the old deck ahead of time, they're removing/jack hammering the concrete steps that were hidden under the old deck, re-grading the yard and drilling in screw piles for the new deck. Railing will be wood with metal balusters, and there will be two sets of steps, one being 8' wide on the side where we're installing interlock and a hot tub and the other on the opposide side that will be 3' wide as a sort of accessory entrance to the deck.

I am also in Ottawa but I am replacing my existing 12x16 deck with a PT 12x21 deck. Materials cost me $5k HST included, labour cost me $9.5k. I have railings and 2 gates.
