Do You Need a Permit to Replace Windows in Guelph?
Like-for-like replacement and new or enlarged openings can be treated differently. Confirm the current scope with the City of Guelph.
Like-for-like is different from a new opening
Replacing a window in the existing opening can be treated differently from enlarging an opening, moving it, changing structural framing or creating a new bedroom egress opening. Confirm the current requirement with the City of Guelph for the property and scope.
Questions to ask before ordering
Will the rough opening change? Is a lintel or beam involved? Does the room rely on the window for emergency egress? Is the property subject to heritage review? These questions help identify when municipal review may be needed.
