EV charging for Calgary condos and apartment buildings

CCT 01Treat the parkade as shared infrastructure

Most condo charging projects start with one owner asking to plug in. If the board approves a circuit from the nearest panel, the second request uses the next spare breaker, and the fifth finds none left. By then the corporation has spent its easiest capacity on a few stalls, and there is still no plan for billing, maintenance or the owners who come later.

The alternative is to decide the building’s charging strategy once, then connect individual stalls to it. That usually means three layers:

• A common backbone. Capacity set aside at the service or a distribution panel, plus feeders, busway or cable tray running along the parking levels.
• A control layer. An EV energy management system (EVEMS) that shares the backbone’s capacity among active chargers.
• Stall connections. A branch circuit, a charger and a way to recover the energy cost, installed when an owner wants one.

People use “EV-ready” and “EV-capable” loosely. In general, an EV-ready stall has an energized circuit waiting at it. An EV-capable stall has only some of the pathway or capacity set aside. Define the terms in the board’s own documents so owners know what they are buying into.

CCT 02What the building can supply

A parkade’s charging capacity depends on the spare capacity of the service and the distribution feeding the parking levels, not on the number of stalls. A load study establishes that figure from metered demand, usually a year of it so winter heating and summer cooling are both captured. Services over 200 A need ENMAX CT metering¹, and a demand-billed common-area account already shows its peak on the bill, so much of the data may already exist.

Two Alberta interpretations then decide how much of that capacity each charger uses:

• Without an EVEMS, EV supply equipment is taken at 100% when individual suite feeders are calculated in apartment-type buildings². Hanging chargers off suite panels quickly exhausts suite feeders.
• A charger whose current setting can be changed without an electrician counts at its maximum demand on the branch circuit, feeder or service³. The board should not accept a unit an owner can simply turn up.

The EV parkade capacity calculator shows the difference load management makes. Take a hypothetical 80 kW of spare capacity. At full output of 6.6 kW per charger, it supports 12 chargers. With a managed floor of 1.4 kW per active charger, 57 chargers can share it. Over a 10-hour night with 60 stalls requesting charge, the same capacity delivers about 13.3 kWh per stall. The load study replaces these example inputs with the building’s own figures.

If the study shows the service itself must grow, that becomes a separate project with its own ENMAX process and cost. See commercial service upgrades and the ENMAX commercial service connection guide.

CCT 03Metering and billing are three separate questions

Boards often mix up the utility meter, a submeter and the charger’s own billing. Each comes under different rules.

Any submeter or apportionment meter that sets charges for individual purchasers in a multi-unit complex is a revenue meter⁴. Revenue meters must be of an approved type and be verified and sealed before service⁴. Billing a charging session by time or as a flat fee is exempt at present. Billing by the kWh needs a dispensation or approved, verified equipment⁵. Level 1 and 2 devices put in service before January 1, 2028 can use the dispensation if the owner registers by December 31, 2027⁶. From January 1, 2030 every such unit must be approved and verified or removed from service⁶.

A board planning to charge owners by the kWh should buy chargers with a clear approval path now, rather than replace them later.

CCT 04What the board has to decide

The technical design follows the policy, not the other way round. Before tendering, the board, with the property manager and legal advice on its bylaws and the Condominium Property Act, should settle:

• Ownership. Does the corporation own the backbone and chargers, or does each owner buy a charger that connects to common infrastructure?
• Who pays for what. Common infrastructure, each stall connection, unused capacity reserved for later owners, network subscriptions and repairs.
• Cost recovery. A flat monthly fee, a time-based charge or per-kWh billing, each with its own equipment implications.
• Allocation. How managed capacity is shared when many cars plug in at once. State the charging experience honestly: a load-managed port will not always deliver its nameplate output.
• Change of provider. Whether the corporation can move to another network without replacing hardware.
• Records. Who keeps approvals, drawings, permits and the asset register for the next board.

The condo board EV charging guide walks through the approvals, cost-sharing models and the order of decisions. For the broader picture of common-area systems, suites and electrical rooms, see condos and multi-family.

CCT 05Rowhouses, townhouses and gang meters

Townhouse and rowhouse complexes raise a different problem. Units are often fed from a shared gang meter base, and the stall may be a garage or driveway rather than a parkade. In Calgary, electrification work on a rowhouse with a shared gang-meter service needs a Row Housing Electrification Authorization form, signed by the condo board or homeowner association, submitted with the permit application⁷. An owner cannot bypass the board simply by hiring a contractor.

A homeowner permit is not an option either. Calgary homeowner permits do not cover EV charging wiring or EV energy management systems⁸, and they are not available in apartment-style condominiums⁸. Every charger in the city needs an electrical permit⁷, and in a multi-unit building that means a contractor’s permit held by a master electrician⁹.

A detached, freehold house with its own service is a residential job, outside this site’s scope. The sister site CalgaryElectricians.ca covers home chargers.

CCT 06Scope table: who does what

Parkade work also touches fire separations, sprinkler and lighting routes, and resident parking during installation. Put those interfaces in the scope rather than leaving them to the site meeting. The commercial electrical permits guide explains what the City expects before inspection.

CCT 07Funding status and what the rebates imply

The City of Calgary’s ChargeYYC program was built for multi-residential buildings, but its first intake closed on November 18, 2025. The City says it anticipates reopening in the future¹⁰. Its terms show which costs the City considered eligible:

• EV Enabled Rebate: 50% of electrical upgrade costs to make parking EV-ready, up to $6,000 per stall and $90,000 per property¹⁰.
• EV Charger Rebate: 50% of Level 2 charger purchase and installation, up to $1,000 per single-port or $2,000 per dual-port station, to $10,000 per property¹⁰.
• Road map grant: the lower of $4,000 or 50% of an EV charging road map for an existing building¹⁰.

These are caps, not typical costs. The federal ZEVIP program, which also funded multi-unit residential charging, is closed for applications¹¹. A board that prepares its road map and load study now will be ready if an intake reopens, but it should not count any rebate until one does.

For budgeting, the commercial and condo EV charging cost guide explains the federal per-port study, the permit fee arithmetic and the operating cost of the common-area account.

CCT 08A sequence that survives the AGM

1. Survey owners on current and expected EVs, stall assignments and preferred cost recovery.
2. Commission a load study and road map covering capacity, a phased backbone and the EVEMS approach.
3. Adopt a policy on ownership, cost sharing, allocation and billing, with legal advice.
4. Procure the design and installation against the road map. Compare backbone and per-stall prices separately, using the bid comparison checklist.
5. Permit, install and inspect, then commission billing as well as charging before owners rely on either.
6. Connect later stalls to the plan rather than reviewing each request from scratch.

Property managers running several buildings can use the same template across the portfolio; see property and facility management. Workplace and fleet charging are covered separately under EV charging for workplaces and fleets.
