How do I know if my property needs a Demolition Control application or just a standard building permit?

It depends on three things: whether a building permit has already been issued for whatever replaces the structure, whether the demolition removes a residential unit, and whether the property sits inside Ottawa's mapped Area of Demolition Control. If all three are true, a separate Demolition Control application applies on top of the standard permit. We check this for your specific address as part of the quote process.
