Decks, Porches and Stairwells

Decks and Porches

Decks and porches are features of many residential properties. If you are planning to construct a new porch or deck first determine your property's zoning designation so that you can review the corresponding zoning regulations.

Notwithstanding any of the regulations, encroachments and/or projections are not permitted within a minimum required setback to a Greenbelt zone as identified in Table 4.1.8.1 of Zoning By-law 0225-2007, as amended. You can find these, and other regulations, pertaining to decks in Part 4 : Residential Zones of the Zoning By-law.
