Permit for deck.

I am in mississauga.. looking to build a 38x16 ft deck .. (less than 2 ft from grade). It will be attached to the house (open on three sides). as well as have a roof (shingle) over the entire portion..

https://www.mississauga.ca/publication/ ... -schedule/

I took a look at the permit fee structure .. and see I need a permit for $174.. is there any sq ft. Multiplier required or deck is flat fee ??? Little unclear on that part.

Not sure if there is an additional charge for the roof part ?

Also..
If I am also doing a shed at the same time 16x10 (15 sq m) .. x $6.24
Do I just apply on the same permit .. to save the min fee ?. Or do I need a totally separate permit for that along with another $174

Thanks for the help.

Has shed size not requiring a permit been increased from 108 sq ft yet?....code change is in the works if not already in effect.

I'm too busy at moment to check, posted so you can look into. Size is going to 15 sq m which is roughly 161 sq ft, 16 x10 will not require a permit.

Will the deck roofing extend out from the house?

Yes I saw that ..but not sure when it will come into effect.
Also think that 10ft setback from the fence is crazy.. which will just mean a variance permit anyway.

You may need to check with the municipality to determine if what you are proposing is allowed or if you will need permission for a variance to the zoning bylaw. I know in Ottawa, the maximum allowance for a projection like what you are proposing is 2m from the main dwelling.

My Neighbour built one of those. It is not a deck, it is considered an extension of the house. Entirely different permits needed. You also have to tie it into the existing structure of the house. They needed engineering drawings, multiple visits through the construction process from the city for permits. A mason was needed to remove bricks to tie it into the existing structure, then to seal the house back up. He also needed existing drawings of the house structure for the engineer to make sure the new roof when tied in would handle wind and snow loads.

From what I have seen.. most of the time they tie the roof into the 2nd floor rim joists. Just like how the deck gets tied into the first floor rim joists.
3 neighbors build decks around me.. smaller than what I'm proposing.. but with roofs. No one took out any bricks.

They either did it wrong or cheap. Maybe without proper permts as well. You need to get behind the brick to get proper flashing in and not depend on caulking that will fail. Depending how the brick work is affected you may need to install a brick ledger to continue carrying the brick load.

Curious here, are you planning to do your own work? Or would be hiring?

Did some digging .. I think I'm ok with bylaw.

Just need to know what the required permits are.

On the porch.. probably a 60/40.. hire out 60%.. and do the finishing myself.
On shed.. just get a pad poured... build myself.

There are safe and legal ways of attaching a roof ledger to brick veneer without removing any bricks. I did it myself 2 years ago. I posted about it in another thread, I will look for a link to it rather than re-explain it here. It wasn’t hard or complicated (any decent contractor could pull it off) and was quite a slick solution.

Call the city just to be sure. Like the other poster said, I believe what you are trying to do will be regarded as an extension to the house, not a standalone porch or deck.

Nobody here works in the building permit department of Mississauga. Not sure what you expect in terms of answers, but you still have to call the city and apply for permits. Answers here are largely irrelevant to your next steps.

Suddenly the focal point of all backyards is the shed set dead nuts in the middle to get 10 feet on all sides. Meanwhile, your house can be 1 meter away from the lot line.

From my experience dealing with Mississauga is a PITA. I had a project where I was infilling some rear windows, Zoning department flagged it and wouldn't close the report until Planning accepted it wasn't an issue. I thought it was such a senseless request.

Onto OP's project, the moment you start dealing with any structure especially attaching to the existing house you will require a building permit. Zoning will also get involved, which means you require a Site Plan. In order to put together a site plan, you need a legal survey. It is a loooong drawn-out process which is probably why people build without a permit. Goodluck!

What.. u mean all the folks on RFD harping on pulling permits .. and it's not easy process !!.

My post is to check if anyone in Mississauga has gone through this for a deck .. and so far I see your point.... last year I saw 4 decks go up behind me.. 2 have roofs... but don't think any permits were taken.

Thanks for the luck.. looks like I'll need it.

I have done something similar, but mine was 2.5ft above ground.

We had to get structural enginner drawings and apply to the city. Structural engineer charged about $1500 and the city another $500 or so.

I believe, if yours doesn't have a roof, you can just do the drawings yourself (thats what the city inspector told me anyways)

But since your roof is going to be attached to the house, you may need full permits. You can obviously try to do it without a permit, but always a risk that 1, someone complains and you have to take it all down, and 2 god forbid something happens.

Hope this helps, goodluck.

If you're ever curious you can look up all permits on any property in Mississauga at this site. Just enter the address and you can see them all there (if there are any).
