Framing is the skeleton of every building — the structural framework that supports walls, floors, roof, and everything attached to them. Whether you're building a new Ottawa home, adding an addition, converting a garage, or framing a commercial space, the quality of the framing determines the quality, safety, and longevity of the entire structure. Ottawa's building requirements demand framing that handles extreme snow loads, wind, and temperature variations. This guide covers everything you need to know about framing contractors in Ottawa — from wood vs. steel framing to costs, building codes...

Different construction types require different framing approaches:
The standard for residential construction in Ottawa. Walls are framed one storey at a time, with each floor platform supporting the walls above. Uses dimensional lumber (2×4, 2×6, 2×8, 2×10, 2×12) and engineered lumber products. Most Ottawa homes, additions, and garage conversions use platform frami...
Light-gauge steel studs used for interior partitions (commercial and some residential) and exterior walls (commercial construction). Steel framing is non-combustible, perfectly straight, resistant to rot and insects, and dimensionally stable (doesn't shrink or warp like wood). Common in Ottawa comme...
Large timber members (6×6 and larger) joined with traditional joinery or modern connections. Creates dramatic open-span interiors without interior bearing walls. Popular for Ottawa custom homes, cottages, and additions where architectural character is desired. Cost premium: 50–100%+ over standard fr...
Framing costs include labour and materials: Residential Wood Framing: Exterior walls (2×6): $8–$15 per sq ft of wall area Interior walls (2×4): $5–$10 per sq ft Floor framing (joists, subfloor): $6–$12 per sq ft of floor area Roof framing (rafters/trusses): $8–$16 per sq ft of roof area Project Estimates: New home framing (2,000 sq ft): $40,000–$80,000 Addition framing (400 sq ft): $12,000–$25,000 Garage framing (2-car): $8,000–$15,000 Basement framing (interior walls): $3,000–$8,000 Deck fram...
Ottawa follows the Ontario Building Code with local amendments. Key framing requirements include: Exterior Walls: Minimum 2×6 framing at 16 inches on centre (required for insulation depth — minimum R-24 for walls in Ottawa). Header sizes above windows and doors must be calculated based on span and load. Bracing requirements per the OBC for wind and seismic resistance. Floor Framing: Joist sizing based on span, spacing, and species. Maximum spans are specified in the OBC span tables. Engineered...
Framing quality determines everything else about your building: Experience: Choose a framing crew with specific experience in your project type (new homes, additions, commercial). Residential and commercial framing require different skill sets and knowledge bases. Code Knowledge: Your framing contractor must understand the Ontario Building Code as it applies in Ottawa — snow loads, insulation requirements, fire separation, and engineered component installation. Ask about specific code requirem...
Both materials have advantages in Ottawa construction: Wood Framing Advantages: Lower material cost for residential construction. Easier to work with (cut, shape, attach). Provides natural insulation (wood has higher R-value than steel per inch). Readily available from Ottawa lumber suppliers. Most residential contractors are skilled in wood framing. Easy to modify during construction. Wood Framing Disadvantages: Susceptible to moisture, rot, and insects if not protected. Dimensional lumber ca...
Residential wood framing costs $8–$15 per sq ft for exterior walls, $5–$10 for interior walls, and $6–$16 per sq ft for floors and roofs. A new 2,000 sq ft home costs $40,000–$80,000 for framing. An addition (400 sq ft) costs $12,000–$25,000. Steel framing adds 10–25% for residential.
Yes. The Ontario Building Code requires minimum R-24 wall insulation for Ottawa's climate zone. This requires 2×6 framing (5.5 inches deep) at minimum to accommodate adequate insulation. Some high-performance homes use 2×8 walls or double-stud walls for even higher insulation values.
A typical 2,000 sq ft Ottawa home takes 2–4 weeks for complete framing (walls, floors, roof, including sheathing and housewrap). Additions take 1–2 weeks. Basement framing (interior partitions) takes 2–5 days. Weather, crew size, and complexity affect timelines.
Ottawa's design ground snow load is 2.4 kPa per the Ontario Building Code. Roof trusses and rafters must be engineered to handle this load plus rain-on-snow and drift loads. All roof trusses in Ottawa must be designed by a P.Eng and manufactured to specification.
Load-bearing walls typically run perpendicular to floor joists, sit above a beam or wall below, and support floors or roof above. Never remove or modify a wall without first confirming whether it's load-bearing. When in doubt, hire a structural engineer ($500–$1,500) — the cost is a fraction of potential structural damage.
