What an application usually includes

- The fixture count for the fee
- A floor plan if walls or openings change
Local quirks
- A low deck still needs a permit if it's attached to the house. One City list suggests otherwise; the deck page is the one to follow.
- Pool fences must be at least 1.53 m (60 in) high, taller than in many Ontario cities.
- London has opted out of the Line Fences Act: if neighbours can't agree, costs are only shared for a 1.22 m (4 ft) chain-link fence.
