Decks & Porches

Decks, porches and canopies, with the footings sized for the load.

Designed to code, permitted and built by one team. The London porch on our project list turned the front of the house into covered outdoor space, and the Strathroy canopy did the same at the back.

Process: 4 steps from first call to sign-off.

Four steps, with the footing inspection setting the pace.

  1. Site visit

    We look at the grade, the wall the structure will attach to, the access for materials and how you want to use the space.

  2. Design & permit

    Drawings for the permit, with the structure sized in-house, filed with the city and answered at no extra charge.

  3. Build

    Locates, footings, framing, decking or roof, guards and stairs, inspected at the footing and framing stages.

  4. Finish & close out

    Railings, lighting and finishes, the final inspection, and the permit closed.

    Karl Sarkadi

  • Legal Basement

    I used them to get a permit from the City of Barrie to legalize my basement apartment … they took care of all the drawings and dealt with the city's requirements so I didn't have to stress about it. … what could've been a huge headache turned out to be smooth and painless.

    Anatoly Dobrovinsky

Before you call

FAQ: decks & porches, answered.

Anything we haven’t answered here, we’ll answer on a call. The first consultation is free.

(416) 990-9179
  • Not for a simple deck within the code’s span tables. For a roofed porch, a canopy, a tall deck or unusual spans, the municipality may ask for a stamped design. We draw either way and add the P.Eng stamp when it is needed.

  • Sometimes. An old footing can stay only if it goes deep enough for the soil, is big enough for the new deck’s load and sits where a new post will land. A roof over the new deck adds load that footings sized for an open deck may not carry. We check the old footings before the new deck is drawn, and the set shows which stay and which are replaced.

  • The structure has to carry the roof as well as the floor. The posts, beams and footings take the roof and its snow load, so each one is sized for that extra weight. We design all of it in-house and show it member by member on the drawings.

  • From a written scope, after the free first consultation and a site visit. Size, height above the ground, whether it has a roof, the decking and railing you pick and the footings your soil needs all move the figure, and the municipality’s permit fee sits on its own line.

  • Yes. The city wants drawings of what exists and what has to change to meet the code, then an inspection. Often the footings or the guard are the problem. We prepare the drawings, do the corrective work and close the permit.

  • The permit review comes first, and its length depends mostly on how complete the application is and on how many examiner comments come back. After that, the deck’s size and whether it has a roof set the length of the build. We give you a schedule with the quote.

  • The deck set in our drawing samples shows what goes in: a framing plan with a schedule for the posts, beams and piers, an elevation of the deck against the house and the grade, and a section through the ledger and the pier connections. The examiner checks those sheets, and our crew builds from them.

  • Both. The same team draws the deck, files the permit and builds it, with our own crew on the footings, framing, decking and guards. If you already have a builder, we can prepare the permit drawings on their own.

  • Only if its walking surface is more than 600 mm above the surface within 1.2 m of it. Then Ontario’s 2024 Building Code requires a guard on every open side. For a house the guard must be at least 900 mm high, or 1,070 mm once the deck is more than 1.8 m up. We draw the guards to those heights on the permit set and build them that way.

  • In most cases, yes. The ledger board bolts into the house framing, but brick veneer and a cantilevered floor each need a different detail, and some decks are better on a beam of their own beside the wall. We look at the wall at the site visit and design the ledger for that house.

  • We build with either. The choice is mostly about upkeep: pressure-treated wood costs less to buy but needs regular staining and sealing, and composite costs more up front and does not. We can price both in the written scope so you can compare them on your deck.

  • That depends on what you are building and on your municipality’s rules, so we check both before anything is drawn. A roof over the patio, or a frame fastened to the house wall, puts load where an open freestanding pergola does not. If a permit is needed, we draw the set with the posts and footings sized for that load.

  • Usually, 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

Deck permits in Ontario: application to final inspection

A deck job counts as construction under Ontario’s Building Code Act when it builds, extends, materially alters or repairs the structure. That covers a new deck, a roof put over an old one and a new set of footings. It covers repairs too, so fixing a deck can need a permit.

After the permit is issued, the inspector checks the deck at the stages the permit lists, ending with the finished deck. The permit then stays open until every required inspection has passed and the municipality closes it, so on the decks we build we book the final inspection and see the file closed.

Deck footing depth under the Ontario Building Code

Ontario’s 2024 Building Code ties minimum foundation depth to the type of soil. In clay or soils that are not clearly defined, foundations containing no heated space must go at least 1.2 m below finished ground and not less than the frost depth, unless local experience with the soil or a foundation design supports a lesser depth.

These depths do not apply to a small deck that is one storey or less, no more than 55 m², has its joists no more than 600 mm above finished ground, supports no roof and is not attached to another structure (an attached deck can qualify only if it is shown that differential movement will not harm that structure). We check a deck against that list before its footings are drawn.

Conservation and grading permits for a deck

A deck near a valley, a wetland or a shoreline inside a conservation authority’s regulated area can need that authority’s permit as well as the building permit, since building a structure there counts as development activity. Levelling the yard for it can bring in a municipal site alteration by-law too. We check both against the survey before the footings are set out, and our site engineering team draws any grading plan needed.
