Local Context
Duplex Framing in Burlington
Understanding duplex framing
What the crew checks in Burlington
Burlington requires Pre-Building Approval before the building-permit submission for house additions. That approval can coordinate zoning, grading, drainage and tree review. Materials or equipment kept on a City road require a road-occupancy permit.
Burlington requires inspection before construction is covered or carried past the applicable stage, so the duplex frame stays open until its stage clears. Alterations to a designated property can require a heritage permit before the building work proceeds. Pre-Building Approval can still be required where the unit work changes the building, grading, drainage or trees.
What belongs in the Burlington site scope
At the address, we verify unit layout, bearing lines, openings and separation details. We also confirm how lumber, engineered members and site access will reach and move through the work area. The quote separates structural changes, unit layout, separations, openings, services and access. Any unresolved drawing, access or inspection condition is named instead of being priced as if it were settled.
The systems and conditions that change the work
A side-by-side duplex concentrates the dwelling-unit boundary in a vertical wall; a stacked duplex also relies on a horizontal floor-ceiling separation. That means your engineer may need to settle the load path before material is ordered.
Adding a secondary unit to an existing house is not automatically the same design exercise as a purpose-built duplex. Existing-building and secondary-suite provisions can apply, which means your quote carries the matching member layout, connector schedule and site handling.
A dwelling unit containing two or more storeys, including a basement, generally requires a 1 h separation from the rest of a Part 9 residential building, subject to the stated exceptions. That means you get the route supported by the drawings instead of a choice made from habit.
The secondary-suite alternative in OBC 9.10.9.16(4) uses continuous smoke-tight Type X gypsum protection and cannot be applied to an unrelated assembly by analogy. That means your following trades inherit that system's spacing, openings and limits.
Problems worth preventing before they disappear behind finishes
Failure: treating municipal permission for two units as approval of the construction details. Prevention: obtain the permit and frame the approved Code design, which means you do not inherit that condition after it is concealed. Failure: locating the unit boundary from a marketing plan. Prevention: coordinate the architectural, structural and fire-separation drawings, which means you can correct the load path or assembly while the work remains accessible.
Failure: placing a stacked bearing wall over an unsupported joist field. Prevention: align or design the support path below, which means your approved repair is documented before the next trade arrives. We stop a conflict involving a side-by-side duplex concentrates the dwelling-unit boundary in a vertical because you need the designer's answer before an improvised fix becomes permanent.
Plans, sequencing, and site decisions
Member and fastening decisions that affect the result
Loadbearing studs use Stud, Standard or No. 2 grade lumber under the Part 9 table, while non-loadbearing studs can use the listed lower grades. That means your installed member must match the grade or product shown in the design. Framing lumber is installed at no more than 19 percent moisture content, which means you can verify the material condition before it is enclosed.
Floor-joist end bearing is at least 38 mm unless the permitted ribbon-board support is used, which means your bearing and connection detail must preserve that capacity. Beam ends require at least 89 mm of even, level bearing unless the applicable span-table note says otherwise. That means you can trace the fastening requirement to the actual assembly.
The hold point and the trades waiting after it
Ontario requires notice when Part 9 structural framing and the heating and air-conditioning ductwork and piping are substantially complete. That means your sequence must reach that visible hold point before finishes. The Code prescribes a two-day inspection response after notice, excluding weekends, holidays and closed-office days, which means you can plan the following trade around the stated response.
The local building department identifies and performs the required inspections; the permit holder must request them. That means your mechanical and electrical work may have to be complete before the framing review. Drywall and firestopping trades inherit the unit-boundary framing, supported edges and coordinated penetrations, which means you avoid reopening work the municipality needed to see.
What to send for a useful quote
Address, approved unit count, zoning confirmation, permit status and new-build or conversion scope, which means you give the estimator the current design basis. Coordinated architectural, structural, fire-separation and mechanical drawings, which means your takeoff can include the scheduled members and openings. Add the address, permit status and target start window, so you can separate what is ready to price from what still needs a decision.

FAQ
Duplex Framing FAQ
Does duplex framing need a permit in Burlington?
It depends on whether the scope is permit work. For a house addition, Burlington requires Pre-Building Approval before the building-permit submission.
What must be ready for the local inspection?
The issued permit package and the work for that inspection stage must be ready. Keep the approved drawings and permit card on site. Do not cover work or move beyond the listed stage before inspection.
Can Duplex Framing materials or equipment use public space?
Only when the applicable municipal approval allows it. A road-occupancy permit is required when construction materials or equipment stay on a City road.
What should I send for a duplex framing quote?
Send the address, current architectural and structural drawings, permit status and clear site photos. For this scope, the quote also needs structural changes, unit layout, separations, openings, services and access plus the proposed route for lumber, engineered members and site access.
Not sure the drawings are ready?
Most are not, and that is fine. Send what you have and we will tell you what is missing before it costs you a week on site.
