Deck & Porch Permit
Drawings in Ontario
Permit-ready deck and porch drawings for new decks, covered porches, raised platforms, stairs, guards, footings, and structural connections. We prepare clear drawings for municipal review and safe construction.
Deck and Porch Permit Drawings: Clear, Buildable, Review-Ready
A deck or porch may look simple, but the permit drawings need to show how the structure will safely support people, furniture, guards, stairs, snow loads, and connections to the house. Municipal reviewers often look closely at footings, posts, beams, joists, guards, stair details, and ledger connections.
GranDesign Engineering prepares deck permit drawings and porch permit drawings that are clear for City review and practical for contractors to build from. Whether you are planning a backyard deck, a covered porch, a raised platform, or a replacement deck, we help organize the drawings so the permit process is smoother.
We are not a general contractor. We prepare the permit-ready drawings, structural details, and engineering notes needed for your deck or porch permit package.

What We Provide for Deck & Porch Permits
Deck and porch permit applications usually need more than a sketch. The drawings should show the size, height, framing, supports, foundations, guard conditions, stairs, and how the structure connects to the existing home. We prepare the details so the permit package is easier to review and easier to build.
- Deck permit drawings and porch permit drawings for new construction, replacement decks, and raised platforms
- Deck layout plan showing dimensions, height, stairs, landings, guards, and relationship to the house
- Structural framing details for beams, joists, posts, ledgers, hangers, and connections
- Footing details, frost-depth notes, pier locations, and support spacing for safe load transfer
- Guard, handrail, stair, landing, and porch roof support details when they apply
- Revisions and clarification responses if the municipality requests changes during permit review
If your deck is attached to the house, elevated above grade, includes a roof, or has complex stairs and guards, proper drawings can help prevent review delays and construction surprises.
Common Deck & Porch Projects We Support
Different deck and porch types require different details. A low platform deck may be straightforward, while a raised deck, covered porch, or deck attached to brick veneer may need more careful engineering and connection notes.
Raised Decks, Stairs, and Guards
Raised decks need clear framing and safety details. We show beam sizes, joist layout, post supports, stair geometry, guard requirements, and connections so the deck can be reviewed and built properly.
- Beam, joist, and post layout
- Stairs, guards, handrails, and landings
Covered Porches and Porch Roofs
Covered porches need roof framing, posts, beam supports, foundations, and connection details. We prepare drawings that show how the porch roof and supports safely transfer loads.
- Porch roof and post support details
- Footings, framing, and connections

FAQs
Do I need a permit to build a deck in Ontario?
Many deck projects require a building permit, especially when the deck is attached to the house, elevated above grade, includes stairs or guards, or has structural supports. Requirements can vary by municipality, so it is best to confirm the permit scope before construction.
What drawings are usually needed for a deck permit?
A typical deck permit package may include a site plan or location plan, deck layout, framing plan, footing details, beam and joist sizes, post locations, stair details, guard details, and connection notes. More complex decks may need additional structural details.
Do porch roof drawings need structural engineering?
Often, yes. A covered porch or porch roof must transfer roof, snow, wind, and dead loads safely through beams, posts, and footings. We provide structural details when the porch roof, supports, or connections need to be shown for permit review.
Can you prepare drawings for an existing deck replacement?
Yes. We can prepare permit drawings for deck replacement, rebuilds, and upgrades. If the size, height, structure, stairs, guards, or attachment method changes, the drawings should clearly show the proposed construction.
What details are important for deck footings?
Deck footing details should show location, size, depth, spacing, and how posts connect to the foundation support. In Ontario, frost protection and proper load transfer are important considerations for safe long-term performance.
Can you help if the City asks for deck permit revisions?
Yes. If the municipality requests clarification or revisions related to our deck or porch drawings, we can update the package and provide the information needed for review.
