What is the cost to wire a new addition in Ottawa?

Wiring a new addition in Ottawa typically costs $8-15 per square foot for basic electrical, or $2,400-$4,500 for a 300 sq ft addition, though costs can reach $6,000+ for larger or complex projects.

The total cost depends heavily on the size of your addition, electrical requirements, and how accessible your existing panel is. A basic 300 square foot addition with standard lighting, outlets, and switches will run $2,400-$4,500. Larger additions of 500-800 square feet typically cost $4,000-$8,000 for electrical work.

Key factors affecting your cost include:

Your electrical needs significantly impact pricing. Basic wiring includes general lighting circuits, outlet circuits meeting Ontario Electrical Safety Code requirements, and switches. However, if you're adding a kitchen, bathroom, or dedicated circuits for appliances like electric heat, air conditioning, or a hot tub, costs increase substantially. Kitchen additions require dedicated 20-amp circuits for countertop outlets, proper GFCI protection within 1.5 meters of sinks, and potentially 240V circuits for electric ranges or cooktops.

Panel capacity and upgrades often drive additional costs. Many Ottawa homes, especially those built before 1990, have 100-amp panels that may lack capacity for a significant addition. If your panel needs upgrading from 100A to 200A to handle the additional load, add $2,000-$3,500 to your project cost. Your electrician will perform a load calculation to determine if an upgrade is necessary.

ESA permits and inspections are mandatory for all new addition wiring in Ontario. Your licensed electrician will pull the necessary permits (typically $100-$200) and coordinate ESA inspections. The work must meet current Ontario Electrical Safety Code requirements, including AFCI protection for bedroom circuits and proper GFCI placement in wet locations.

Accessibility challenges can increase labor costs. If your existing panel is in a difficult location or requires extensive wire runs through finished spaces, expect higher pricing. Running wire through unfinished basement areas is much more cost-effective than fishing wire through finished walls.

For an accurate estimate on your specific addition, consider factors like whether you need 240V circuits, the number of outlets and switches, lighting requirements, and any special electrical needs. Most Ottawa electrical contractors offer free estimates to assess your project's unique requirements.
