Ontario Design Studio prepares BCIN-certified deck permit drawings for the City of Vaughan - attached decks, elevated and multi-level decks, covered porches, and screened enclosures across Woodbridge, Maple, Thornhill, Kleinburg, and Vellore. Vaughan's building department reviews decks for structure, footings, guards, and stairs, and a well-detailed drawing set is the fastest route to approval.
When You Need a Deck Permit in Vaughan
A building permit is required in Vaughan when your deck is:
- Attached to the house (a ledger connection)
- More than 600 mm (24″) above grade
- Larger than 10 m² (about 108 sq ft)
- Covered or roofed, or enclosed as a sunroom
- Serving as a required means of egress from the house
Small, freestanding, ground-level decks below these thresholds are often exempt - send us your plan and we'll confirm whether you need a permit before you spend anything.

Deck Structural Requirements (OBC)
Decks are deceptively structural, and examiners scrutinize a few details closely:
- Footings below the frost line - generally about 1.2 m (4 ft) deep in Vaughan - to prevent frost heave
- Guards at least 900 mm high (1070 mm where the walking surface is more than 1.8 m above grade), with baluster gaps under 100 mm
- Ledger connection properly bolted and flashed to the house to prevent water damage and collapse
- Beam and joist spans sized to the load - larger and multi-level decks may need engineered structural design
Covered Decks & Porches
Adding a roof turns a deck into a covered porch, which brings roof loads, posts, and beams into the design and often requires additional structural detail. We design covered decks, pergolas, and screened enclosures to the same code standard as the deck itself.
