Deck Permit Drawings in Simcoe County and the Lake Simcoe Area

Deck Permit Drawings in Simcoe County, Bradford & Lake Simcoe Area

If you’re building a deck in Oro-Medonte, Bradford West Gwillimbury, Innisfil, Georgina, or anywhere around Lake Simcoe, you already know a permit is part of the job. What slows projects down is waiting on the drawings.

ARCH Drafting Company prepares deck permit drawing packages for builders and homeowners across Simcoe County and the Lake Simcoe area. Two-week turnaround. Permit-ready on first submission.

Do you need a permit to build a deck in Ontario?

In most Ontario municipalities, yes. A deck that is attached to the house, elevated more than 600mm above grade, or part of a larger structure will require a building permit. That permit requires drawings.

The specific trigger varies slightly by municipality. Oro-Medonte, Bradford West Gwillimbury, and the townships around Lake Simcoe each have their own building departments, but the underlying requirement comes from the Ontario Building Code. If the deck is attached or elevated, assume a permit is needed and plan accordingly.

Building without a permit creates real problems down the road — failed inspections, required demolition, complications on resale. For builders especially, it’s not a risk worth taking.

What deck permit drawings need to include

A complete deck permit drawing package for an Ontario municipality typically includes:

A site plan showing the deck location on the property, setbacks from property lines, and the relationship to the existing house. Setbacks are where a lot of decks run into issues — particularly on rural or waterfront lots where lot lines aren’t always where people think they are.

A floor framing plan showing joist sizing, spacing, beam layout, post locations, and footing positions. This is where the structural logic of the deck gets documented for the building department reviewer.

Elevations showing deck height above grade, guard height, and stair configuration. Guard requirements under the Ontario Building Code are specific — height, baluster spacing, and top rail loading all need to be addressed.

Construction details covering the ledger connection to the house, post-to-beam connections, footing design, and any other connection or assembly the municipality wants to see documented.

A complete package gives the building department everything they need to issue a permit without going back and forth. That’s what keeps the project on schedule.

Steel deck framing is showing up everywhere out here

One thing that’s hard to miss in Simcoe County and the Lake Simcoe area right now is how many decks are being framed with steel. Products like Fortress Evolution steel deck framing have become a common sight on builds in Oro-Medonte, Bradford, Innisfil, and the surrounding townships.

It makes sense for this market. Steel framing is prefabricated, consistent to work with, and built to last without the rot, warping, or ongoing maintenance that comes with pressure-treated lumber — especially important on waterfront and rural properties where exposure is higher and access for repairs isn’t always easy. For builders running multiple projects, it also speeds up the framing phase significantly.

What it doesn’t change is the permit requirement. A steel-framed deck still needs a building permit, and the permit drawings still need to show the same information: framing plan, post and footing layout, guard details, ledger connection, and site context. The material is different; the documentation requirements are the same.

Decks on waterfront and rural properties

A lot of the deck work around Lake Simcoe and Simcoe County involves properties that come with their own complications — waterfront setbacks, Conservation Authority jurisdiction, sloped lots, older houses without much documentation.

Waterfront properties in this area often fall under Lake Simcoe Region Conservation Authority oversight. Depending on where the property sits, a permit from the Conservation Authority may be required alongside the municipal building permit. That’s worth confirming early before drawings are started.

Sloped lots also affect the design more than people expect. A deck that sits close to grade on one side can be well above 600mm on the other, which changes the guard requirements and sometimes the footing design. Getting the existing grades documented before drawing starts avoids surprises mid-review.

Why turnaround time matters for deck projects

Deck season in Ontario is short. A builder who needs to pull a permit in May doesn’t have three weeks to wait on drawings and another three weeks in the municipal queue. The drawings need to be right and they need to be ready.

ARCH turns around deck permit drawing packages in two weeks. For builders running multiple projects or homeowners trying to hit a construction window, that timeline is the difference between a deck that gets built this season and one that waits until next year.

What ARCH Drafting Company needs to get started

To prepare a deck permit drawing package, we typically need a recent survey or site plan showing the property and existing house footprint, basic project information including deck dimensions, height, and proposed layout, and confirmation of which municipality the permit will be submitted to.

If a survey isn’t available, we can work with what exists and flag any gaps before submission.
