- Where to apply
- City of Mississauga ePlans
- Review time
- Pre-screening takes 7 to 10 business days, then the first review of a complete house application takes 10.
The City's sample drawing shows concrete piers at least 1,200 mm below grade and a ledger lag-bolted into a solid foundation wall. Plans also have to show the soil bearing capacity and guard heights.
What an application usually includes
Mississauga’s checklist has the exact list; apply through City of Mississauga ePlans.
- A site plan with the lot lines, the house and the deck, with distances
- A framing plan: joists, beams, posts and footings with sizes and spacing
- Elevations and sections: guard, stairs, the ledger connection and footing depth
- The application form and the owner or designer declaration
Local quirks
- ePlans wants unlocked greyscale PDFs, one drawing per file, each named to match its title block.
- Resubmissions have no guaranteed review time, and each round can add two weeks or more.
