Common questions about custom home costs in Toronto
Custom home construction in Toronto and the GTA typically ranges from $350 to $600+ per square foot for construction only. A 3,000 sq ft home at premium finish runs approximately $1.2M–$1.5M in hard costs, before land, permits, design fees, and soft costs — which typically add 15–25% on top.
A construction estimate covers hard costs only. It typically excludes: land, building permits, architectural and engineering drawings, interior design, landscaping, and financing costs. In the GTA these soft costs commonly add 15–25% to the total budget.
The biggest cost drivers are: foundation and excavation complexity, structural design, envelope glazing, mechanical and electrical capacity, kitchen and bathroom count, millwork and finish level, and lot-specific conditions such as slope, soil type, or ravine setbacks.
Municipal permit fees for a luxury custom home typically range from $15,000 to $40,000+, not including development charges which can add significantly more in some municipalities. AVL coordinates the permit process and provides estimated fees at consultation.
Basement renovations typically cost $70–$200 per square foot for standard finishing and $200–$350 per square foot for permit-backed, design-led work. Whole-home renovations typically cost $450–$700 per square foot for the renovated area. Full gut renovations of older homes can reach or exceed new build costs when structural, mechanical, and electrical systems need replacement. A consultation with AVL can assess which path makes more sense for your property.
