Electrical Considerations for Home Renovations

Essential Electrical Considerations that Should be Part of Any Home Renovation Project

Planning Your Electrical Future

When embarking on a home renovation project in Toronto or the GTA, electrical considerations should be among your top priorities. Modern homes demand increasingly sophisticated electrical systems to support our tech-filled lifestyles, and renovation projects present the perfect opportunity to upgrade outdated wiring, enhance safety, and prepare your home for future needs. At BradCon Electrical, we've guided countless homeowners through the electrical aspects of their renovation projects, ensuring their homes are not only beautiful but also safe and functional.

Proper electrical planning early in your renovation process can save you significant time, money, and frustration. Let's explore the essential electrical considerations that should be part of any home renovation project.

Assessing Your Current Electrical System

Before making changes, it's crucial to understand what you're working with. A thorough assessment of your current electrical system will inform all subsequent decisions.

Electrical Panel Capacity

Your electrical panel is the heart of your home's electrical system. During renovations, consider whether your current panel can support your planned upgrades and additions.

Signs you may need a panel upgrade:

• Your home has a panel rated less than 100 amps (most modern homes require at least 200 amps)
• You experience frequent circuit breaker trips
• Your panel uses fuses instead of circuit breakers
• You're planning to add major appliances or systems (like central air conditioning or an EV charger)
• You're adding significant square footage to your home

A panel upgrade typically costs between $2,000-$3,500 in Toronto, depending on your specific requirements, but it's an investment in both safety and functionality that pays dividends for decades.

Wiring Assessment

The condition and type of wiring in your home significantly impacts safety and functionality. Older Toronto homes may have outdated wiring systems that warrant attention during renovations:

Types of outdated wiring to look for:

• Knob and tube wiring: Common in homes built before 1950, this wiring system lacks a ground wire and can be a significant safety concern.
• Aluminum wiring: Used in homes built between 1965 and 1975, aluminum wiring can lead to loose connections and potential fire hazards if not properly maintained.
• Ungrounded wiring: Two-prong outlets indicate ungrounded wiring, which lacks the safety features of modern electrical systems.

If your renovation involves opening up walls, it creates an ideal opportunity to replace outdated wiring with modern, safer alternatives.

Code Compliance and Permits

Electrical work during renovations must comply with the Ontario Electrical Safety Code and local building regulations. As of 2025, Ontario has adopted the 2024 Ontario Building Code, which includes updated electrical requirements.

Permit Requirements

In Toronto, electrical work typically requires permits and inspections from the Electrical Safety Authority (ESA). According to Ontario law, electrical work must be performed by a licensed electrical contractor or the homeowner of record.

When electrical permits are required:

• Installing new circuits or outlets
• Upgrading your electrical panel
• Adding or relocating lighting fixtures
• Major rewiring projects
• Any electrical work that involves changes to your service entrance

The permit process ensures your electrical work meets safety standards and code requirements. It also creates an official record of the work completed, which can be valuable when selling your home.

Strategic Planning for New Outlets and Fixtures

One of the most common complaints in older homes is insufficient outlets for today's technology-heavy lifestyle. Renovation projects offer the perfect opportunity to address this issue.

Outlet Placement and Quantity

When planning outlet locations, consider both current and future needs:

• Kitchen areas: Plan for multiple dedicated circuits to accommodate high-demand appliances like refrigerators, microwaves, and dishwashers. Consider adding outlets above countertops for small appliances.
  
  
• Living and entertainment spaces: Install additional outlets for entertainment systems, with consideration for wall-mounted TVs and associated components.
  
  
• Home office spaces: Ensure ample outlets for computers, printers, chargers, and other office equipment.
  
  
• Bathrooms and wet areas: Include GFCI (Ground Fault Circuit Interrupter) outlets for safety in areas where water is present.
  
  

Lighting Considerations

Lighting dramatically impacts both the functionality and aesthetics of your renovated space:

• Layered lighting approach: Incorporate ambient, task, and accent lighting for flexibility and visual interest.
  
  
• Smart lighting systems: Consider pre-wiring for smart lighting controls that allow for customized scenes and remote operation.
  
  
• Energy efficiency: Plan for LED-compatible fixtures and dimmer switches to reduce energy consumption.
  
  
• Future modifications: Install junction boxes in strategic ceiling locations even if you're not adding fixtures immediately, giving you flexibility for future changes.
  
  

Special Considerations for Specific Renovation Projects

Different types of renovation projects come with unique electrical requirements and considerations.

Kitchen Renovations

Modern kitchens are electrical hubs that require careful planning:

• Dedicated circuits: Today's kitchens need multiple 20-amp circuits for major appliances, plus separate circuits for high-demand items like microwave ovens and dishwashers.
  
  
• Island power: If you're including a kitchen island, plan for power access, either through floor outlets or ceiling drops.
  
  
• Under-cabinet lighting: Pre-wire for under-cabinet lighting during the renovation phase to avoid surface-mounted wiring later.
  
  
• Appliance planning: Consider the electrical requirements of all planned appliances, including specialty items like wine coolers or warming drawers.
  
  

Bathroom Renovations

Bathrooms combine water and electricity, creating specific safety requirements:

• GFCI protection: All outlets in bathrooms must have GFCI protection to prevent shock hazards.
  
  
• Ventilation fans: Ensure proper circuits for ventilation fans, which are now required by code in bathrooms without windows.
  
  
• Heated floors: If including in-floor heating, plan for appropriate wiring and controls.
