Calculation Formula

The calculator uses the following formula to estimate home addition costs:

Total Cost = (Base Cost × Addition Type Factor × Square Footage) + (Labor Cost × Home Condition Factor × Quality Factor) + Permit Fees

Where:

Base Cost is the average cost per square foot for the type of addition.
Addition Type Factor adjusts for different types of additions.
Square Footage is the size of your addition in square feet.
Labor Cost is the estimated labor cost based on your home's condition.
Home Condition Factor adjusts for differences in home age and condition.
Quality Factor adjusts for different quality levels.
Permit Fees are estimated based on Ontario building codes.

Worked Example

Let's calculate the estimated cost for adding a 200 square foot bedroom to an average-condition home in Ontario with standard quality:

Base Cost for bedroom addition: $150 per square foot
Addition Type Factor: 1.0 (standard bedroom)
Square Footage: 200 sq ft
Labor Cost: $50 per square foot
Home Condition Factor: 1.0 (average condition)
Quality Factor: 1.0 (standard quality)
Permit Fees: $1,200 (estimated for Ontario)

Total Cost = ($150 × 1.0 × 200) + ($50 × 1.0 × 1.0 × 200) + $1,200
= $30,000 + $10,000 + $1,200
= $41,200

This example shows that adding a 200 square foot bedroom to an average home in Ontario with standard quality would cost approximately $41,200.
