How much does garage build double detached cost in Toronto?

Building a detached double garage in Toronto typically costs $35,000-$65,000, with most homeowners spending around $45,000-$55,000 for a standard 24' x 24' structure with basic finishes.

The cost breakdown depends heavily on your specific requirements and site conditions. A basic double garage (20' x 20' to 24' x 24') with concrete pad, standard framing, asphalt shingles, and basic electrical will fall in the lower range. Premium features like insulation, drywall finishing, upgraded doors, windows, or specialty roofing materials push costs toward the higher end.

Site preparation significantly impacts pricing in Toronto's varied terrain. If your lot requires excavation for leveling, has poor drainage, or needs extensive grading, expect an additional $3,000-$8,000. Properties in older Toronto neighborhoods often face access challenges for equipment, which can add 10-15% to labor costs. The foundation type also matters - a simple concrete slab costs less than a full foundation with footings below the 4-foot frost line.

Material and labor costs in the GTA run 15-20% higher than other Ontario markets due to demand and transportation. Lumber framing typically accounts for $8,000-$12,000, while the concrete pad runs $3,000-$5,000 depending on thickness and reinforcement. Electrical rough-in and service connection adds $2,500-$4,000, though this requires an ESA-licensed electrician and permit. Roofing materials and installation contribute another $4,000-$7,000 depending on your choice of asphalt shingles versus metal or architectural shingles.

Toronto Building Division permits are mandatory for detached garage construction and typically cost $400-$800 plus development charges. The permit process takes 10-20 business days for straightforward applications. Your garage must meet setback requirements (typically 0.6m from property lines), height restrictions (usually 4.5m maximum), and lot coverage limits. Some neighborhoods have additional design guidelines that may require upgraded materials or specific architectural features.

Professional installation is strongly recommended for this scope of work. While handy homeowners might handle some finishing tasks, the foundation, framing, electrical, and roofing require skilled trades. Attempting major structural work without proper experience often leads to costly corrections and permit issues. Most contractors offer turnkey pricing that includes permits, materials, and labor, which provides better warranty protection and ensures code compliance.

Plan for a 4-8 week construction timeline depending on weather, permit processing, and contractor availability. Spring booking (January-February) secures better rates and scheduling for summer construction. Winter builds are possible but may incur weather delays and seasonal material surcharges.
