Electrical Service Upgrades in Multi-Unit Buildings: What You Should Know

If you live in an older condo or strata building, there’s a good chance your electrical system wasn’t built for the way we live today. Electric vehicle chargers, heat pumps, in-suite laundry, and air conditioning are all things that use a lot of power, and when more units start installing them, the electrical load can add up fast.  

That’s why many older buildings are now looking at electrical service upgrades. It’s not just about getting more power, it’s about making sure your building stays safe, code-compliant, and ready for whatever comes next.  

What is an Electrical Service Upgrade? 

An electrical service upgrade increases the amount of power your building can safely handle. It usually involves: 

• Replacing the main service panel or distribution equipment to support higher loads 
• Increasing the overall service capacity so the system can handle new and future demand 
• Working with the utility provider to upgrade not just the service line, but possibly transformers, fuses, and raceways  

This work must always be done by a licensed electrical contractor and always requires permits and inspections. There’s no cutting corners here. 

Why are so Many Buildings Hitting Their Limit? 

If your building was built before the 2000s, it likely wouldn’t have been designed with today’s energy use in mind. Back then, EV chargers and heat pumps weren’t even on the radar, whereas today they’re everywhere. Common upgrades that strain the system include: 

• Electric vehicle chargers 
• Heat pumps and air conditioning units 
• Induction stoves 
• In-suite laundry 

Unlike houses, multi-unit buildings share electrical infrastructure, so when lots of residents upgrade at once, it can push the whole system past its safe limit.  

Signs Your Building May Need an Upgrade 

Here are a few signs that your building’s electrical infrastructure may be due for an upgrade: 

• Breakers are tripping all the time 
• Your electrical panels are running at or near full capacity 
• Residents are being told they can’t install EV chargers due to load issues 
• The building hasn’t had an electrical review or upgrade in 30+ years 

If any of this sounds familiar, or if your strata is planning new amenities, it’s worth getting a professional opinion. 

What’s Actually Involved? 

Every building's different, but here’s what the process usually looks like:  

1. Load Calculation
An electrical licensed contractor or engineer figures out how much power the building uses now, and how much more it will need in the future. They might also recommend energy management strategies to help handle load increases smartly. 

2. Permit and Planning 
The contractor applies for an electrical installation permit, and in many cases, works with the local utility company if upgrades are needed for incoming lines, or other utility-side gear. 

3. Equipment Upgrades 
This could include new main panels or switchgear, bigger feeders or upgraded meters, or 
replacing old breakers and wiring.

Are There Rebates? 

Yes, some EV charger and heat pump-related upgrades may qualify for rebates through programs like CleanBC, BC Hydro, and FortisBC. 

Usually you will need a valid electrical installation permit, a licensed electrical contractor doing the work, and proof of eligible equipment. 

Keep in mind that rebate details can vary, especially when it comes to energy management systems.  

Think Long-Term 

When you’re already investing in a major upgrade, it’s smart to think ahead. Some things to factor in: 

• Future demand for EV chargers 
• The potential for solar panels or battery storage 
• Upcoming HVAC or heat pump conversions 
• Anticipated heat pump or HVAC conversions 
• New appliances or energy demands in individual units 
• Energy management equipment to accommodate new loads 

It often costs less to build in a little extra capacity now than to upgrade again later. 

Upgrading your building’s electrical service might sound like a big job, but it’s also an investment in safety, sustainability, and convenience for everyone who lives there. 

If you’re on a strata council or condo board, start the conversation early. Talk to licensed pros, get a proper load assessment, and make sure everyone’s on the same page. 

With the right planning, you can future-proof your building and support the tech upgrades your residents want.
