Brampton’s checklist has the exact list; apply through Brampton Building and Business Portal.

- Ceiling heights, beams and ducts
- Window details for bedroom escape

Local quirks
- Two zoning by-laws apply right now (270-2004 and the new 14-2026, which is under appeal), and the stricter rule wins. Check both for fences and deck setbacks.
- A pool needs paperwork before digging: Alectra Utilities stamps the site plan first, and fill or road occupancy permits may apply.
