(1) Whether or not the deck serves an entrance or exit; and
(2) The size of the deck.
A building permit is always required for a deck regardless of its size if it serves and entrance or exit. For example, a deck outside of a patio door will require a building permit.
Any deck this is larger than 108 square feet (10 square metres), regardless of whether it is attached or detached to a dwelling, is required to have a permit. However, if you construct a deck under 108 square feet in size setback regulations still apply. A setback is the distance which a deck must be setback from your property line.
To apply for a building permit in Norfolk County, you are required to complete and submit a building permit application along with 2 copies of you construction drawings and 2 copies of a survey of site plan detailing the location of you deck including the setback dimensions from all property lines and the septic system.
