I don't think there are rules against those things as long as lot coverage is respected.
There is a requirement for accessory buildings to be 1m from the main dwelling but I don't recall anything if the buildings are attached. There is a new one on 2nd ave that has an attached rear garage with a narrow walkway from the house.

Edit - From the land use bylaw:
Quote:

A private garage attached to a building may project without limits into a rear setback area provided it:
a
does not exceed 4.6 metres in height, measured from the finished floor of the private garage;
62P2018
b
does not exceed 75.0 square metres in gross floor area for each Dwelling Unit located on the parcel;
27P2011, 62P2018
c
has no part that is located closer than 0.60 metres to the rear property line; and
d
has no eave closer than 0.6 metres to a side property line .

So if you keep the garage under 75 square meters, respect the side and rear setbacks and keep it under 4.6m there is no issue being attached to the main residential building.
