What are typical material and labour costs for hanging and finishing drywall in an Etobicoke basement apartment?

For a typical Etobicoke basement apartment (600 to 900 square feet of living space), expect to pay $6,000 to $14,000 for the complete drywall scope including framing, insulation, vapour barrier, hanging, taping, finishing to a Level 4 standard, and primer. Materials typically account for 30 to 40% of this total ($2,000 to $5,000), with labour making up the remaining 60 to 70% ($4,000 to $9,000).

Basement apartments — technically called secondary suites or accessory dwelling units — are extremely common in Etobicoke, and the Ontario Building Code has specific requirements that directly affect your drywall scope and costs. A building permit is mandatory for creating a basement apartment. The City of Toronto requires permits for all secondary suites, and inspections will verify fire separations, ceiling heights, egress windows, smoke and carbon monoxide detectors, and sound isolation between the basement unit and the upper unit. Do not skip the permit — unpermitted basement apartments create serious liability, insurance, and resale complications.

Material Costs Breakdown

Drywall board selection for a basement apartment is not straightforward because different areas require different board types. The ceiling between the basement apartment and the upper dwelling unit must achieve a minimum 45-minute fire resistance rating and meet STC 50 for sound isolation. This typically requires 5/8-inch Type X fire-rated drywall ($20 to $28 per 4x8 sheet) on the ceiling, often in a double-layer configuration on resilient channel for sound control. Exterior basement walls require standard 1/2-inch drywall ($14 to $20 per sheet) over properly insulated and vapour-barriered framing. Bathrooms and kitchens need moisture-resistant green board ($20 to $28 per sheet) or mould-resistant purple board ($24 to $32 per sheet). Interior partition walls use standard 1/2-inch board.

For a 750-square-foot basement apartment with one bedroom, one bathroom, a kitchen, and a living area, you will need approximately 100 to 130 sheets of drywall across these different types. Add joint compound (four to six 17-litre boxes of all-purpose at $18 to $25 each, plus two boxes of topping compound at $20 to $28 each), paper tape ($5 to $8 per roll, three to four rolls needed), corner bead ($3 to $8 per piece, 15 to 25 pieces), and screws ($15 to $25 per box, four to six boxes). Total materials for drywall alone: approximately $2,000 to $3,500. Insulation (R-20 minimum for basement walls) and vapour barrier add another $1,000 to $2,000.

Labour Costs Breakdown

Hanging drywall in a basement apartment costs $2.50 to $4.00 per square foot for walls and $3.50 to $5.50 per square foot for the ceiling. Basement work carries a premium over above-grade work because of lower ceiling heights (which make manoeuvring full sheets difficult), the need to work around existing mechanicals, and the often awkward access through narrow basement stairways. Total wall and ceiling surface area in a 750-square-foot apartment is roughly 2,500 to 3,200 square feet. Hanging labour: approximately $2,500 to $4,500.

Taping and finishing to a Level 4 standard costs $2.00 to $3.50 per square foot. This includes three coats of compound (bedding coat, filler coat, finishing coat), sanding, and touch-up. For a basement apartment where you want the space to feel bright and welcoming rather than like a basement, a quality Level 4 finish is essential — tenants and potential buyers notice drywall quality immediately. Taping labour: approximately $1,800 to $3,500.

Sound isolation between units is both a code requirement and a practical necessity. The most common assembly uses resilient channel ($1.50 to $3.00 per linear foot) screwed to the ceiling joists, with one or two layers of 5/8-inch Type X drywall screwed to the channel — never into the joists directly, as this short-circuits the sound isolation and defeats the entire purpose. Acoustic sealant ($8 to $15 per tube) is applied at all perimeter joints where the ceiling meets the walls. This assembly adds $2.00 to $5.00 per square foot to the ceiling cost but is essential for meeting the Ontario Building Code's STC 50 requirement.

Toronto's basement moisture reality makes material choices particularly important in Etobicoke. Lake Ontario's proximity keeps humidity levels elevated, and basement walls are in direct contact with the earth. Mould-resistant drywall on exterior walls and in the bathroom is a smart upgrade over standard green board — the fibreglass facing eliminates the paper food source that mould feeds on. At $24 to $32 per sheet versus $20 to $28 for green board, the premium is modest insurance against a costly mould problem.

A basement apartment drywall project requires coordination with your electrician, plumber, and HVAC contractor — all rough-in work must be complete and inspected before drywall goes up.
