Decks & Porches · Barrie
Decks, porches and rear canopies for Barrie houses, designed, permitted and built by one team. We set footings from the survey, size beams and guards to the Building Code, check yard setbacks in By-law 2009-141 and file through APLI with the City of Barrie Building Services.

What’s included
Outdoor structures fail at the ground and at the house: footings that heave and ledgers that rot. We design both properly, then build what we drew. In Barrie the package goes to the City of Barrie Building Services, and it is drawn to that department’s checklist.

How it runs
Four steps, with the footing inspection setting the pace.
We look at the grade, the wall the structure will attach to, the access for materials and how you want to use the space.
Drawings for the permit, with the structure sized in-house, filed with the city and answered at no extra charge.
Locates, footings, framing, decking or roof, guards and stairs, inspected at the footing and framing stages.
Railings, lighting and finishes, the final inspection, and the permit closed.

Before you call
Anything we haven’t answered here, we’ll answer on a call. The first consultation is free.
(416) 990-9179Possibly. Barrie has a site alteration by-law of its own, and we confirm with the City of Barrie Building Services whether it reaches a house lot before the deck is drawn. As a single-tier city, Barrie has no regional by-law to check on top of it.
If the lot is inside the regulated area of the Lake Simcoe Region Conservation Authority (LSRCA), yes. Ontario Regulation 41/24 counts building or enlarging a structure as development activity, so a deck near a watercourse, a wetland or a valley in Barrie can need an LSRCA permit before the City of Barrie Building Services issues the building permit. On the west side of Barrie the Nottawasaga Valley Conservation Authority takes that role instead, so we find out from the survey which of the two maps the lot.
Yes. We take on decks & porches across Barrie, including Allandale and Painswick, within an hour of our Richmond Hill office. The first consultation is free, by phone or on site.
Three things to start: property address; photos of the yard and the wall the structure would attach to; and rough size, and whether you want it covered. Send those and we tell you what the City of Barrie Building Services will ask for before we quote.
The zoning on your lot sets that, not the Building Code. For most of Barrie the yard setbacks come from Comprehensive Zoning By-law 2009-141, and inside the Allandale Major Transit Station Area from the Community Planning Permit System, so we measure against the right one on your survey before the deck is sized. The City of Barrie Building Services reviews the zoning as well as the structure before it issues the permit.
Usually, and on a typical lot without a tree permit, since By-law 2014-115 only regulates trees that belong to a woodlot of half an acre or more. The footings then go outside the main roots, and the framing leaves an opening around the trunk with room for it to grow. If the yard does include woodlot trees, we raise them with the City before the drawings go to the City of Barrie Building Services.
The deck as built, against the drawings the City of Barrie Building Services approved: footing size and depth, beam and joist sizes and spans, the ledger if the deck fastens to the house, and the guards and stairs. We call for each inspection the permit requires as the work reaches it, and you can see the file’s status in APLI between visits.
Yes. On a house in one of Barrie’s established suburban neighbourhoods we first look at what the old porch stands on and at the front wall it ties into. A rebuild that changes the porch’s size or adds a roof is checked against the front-yard setback in By-law 2009-141, and the new footings, framing and guards go on drawings for the City of Barrie Building Services.
Yes. Barrie takes residential building permit applications online through APLI, and a deck goes in that way, with its drawings, for the City of Barrie Building Services. When we prepare the deck we make the application too, so we are the ones who answer the examiner, and APLI’s email notices keep you posted as the review moves.
Usually. We measure the deck, open the ground beside a footing or two to see what it stands on, and draw it as built with whatever has to change to meet the Building Code. The City of Barrie Building Services decides what it needs to see uncovered at inspection, and we file the application through APLI.
Searched & answered
Short answers to the decks & porches questions people search most, and the broader topics they lead to.
Not covered here? Book a free consultationUsually, yes. Each municipality sets its own line. The GTA rules we work with go by the deck’s height above the ground, and some also count any deck fastened to the house. A roofed porch fastened to the house needs one under each of them. Cities word the rule differently, so Fine Engineering checks your municipality’s own wording before a deck is drawn.
Start with drawings and, in most cases, a permit, then build from the ground up. Once the permit is issued, call for utility locates, dig the footings to the depth your soil needs and call in each inspection the permit lists as that stage is reached. Then come the framing, the decking, the guards and stairs, and the final inspection. Fine Engineering draws and builds decks across the GTA.
As part of the deck, on the same permit drawings. The stringers are cut to the drawing and fastened to the deck framing, and the guard rule that applies to the deck applies to the open sides of the stair too. Fine Engineering draws the stair, its stringers and its guard on the permit set.
Either the main roof carries down over the porch, or a lower shed roof hangs off the house wall. Both put new roof and snow load on the house, so the join needs flashing and the existing wall and roof framing has to carry it. Fine Engineering checks that framing before the porch roof is drawn.
For a permit, the zoning by-law decides. Zoning is applicable law, so a permit is only issued for work that complies with it. If a covered porch would take the lot past what its by-law allows, the owner makes the porch smaller or gets a minor variance first. Fine Engineering reads the by-law for your lot, including how it treats a roofed porch, before the porch is drawn.
Most often because water crosses a property line, the ground slopes too gently away from the house, or the swales and elevations do not tie into the survey. Reviewers also return plans that lack erosion control, or an engineer’s stamp where one is required. Fine Engineering designs grading to each municipality’s own criteria and revises the plan to answer the reviewer’s comments.
Good to know
In Barrie the reviewer is the City of Barrie Building Services. Every Barrie lot sets its own terms: the height above grade, the wall the deck fastens to and the soil under the footings decide the design before anything is dug.
We walk the site with the survey on a scheduled visit before anything is drawn, then file the decks & porches package to the City of Barrie Building Services’s own checklist.
Housing in Barrie runs to high-density waterfront condos built since the 1980s beside established suburban neighbourhoods. Our deck work there is on the houses: rear decks and porches with their own footings and guards.
The 230 sq ft rear deck in our gallery is a Barrie project: a compact upgrade framed in pressure-treated lumber, with a pergola over it. Ontario’s Building Code Act counts the extension and material alteration of a building as construction, so upgrading a deck can need a permit as much as building a new one.
Before an upgrade is drawn, we look at what it changes, such as the footings, the footprint or the height, and confirm with the City of Barrie Building Services whether it needs a permit. A pergola added in the same job is part of that check, because a frame fastened to the house or carrying a roof puts load on the structure that an open freestanding one does not.
Not every Barrie lot is zoned under By-law 2009-141. Some Secondary Plan land transferred from Innisfil in 2009 is still governed by Innisfil Zoning By-law 054-04, and the boundary land added on January 1, 2026 by Springwater By-law 5000 or Oro-Medonte By-law 97-95. A deck there is placed to that by-law’s yard setbacks, while the permit itself comes from the City of Barrie Building Services.
Barrie lets a lot hold up to three additional units, and the way into one can cross a deck: a landing outside a basement door, stairs up to a unit over a garage, a porch at a coach house. Where that structure is part of the unit’s exit, we draw it with the unit’s permit rather than as a separate deck.
The Code’s guard heights for decks assume a single house, or a house with a secondary suite: 900 mm up to a walking surface 1,800 mm above the ground, and 1,070 mm higher than that. Where a deck serves more homes than that, we check which Code rules apply before detailing the guards for the City of Barrie Building Services.
