The short answer
A Calgary condo or multi-unit project should review the individual unit and the shared electrical service together. Confirm ownership, metering, board authorization, building demand, permits and any utility changes before assuming a unit panel upgrade creates extra capacity.
01 / Project knowledge
Find the shared boundary
Document the unit panel, feeder, meter and upstream building equipment. A unit may have spare breaker spaces without available capacity on the shared supply. The electrical project team needs the building information as well as the owner’s equipment list.
Ask the board, association or property manager who owns each part and who can authorize access and outages. A unit-level quote can exclude work that must be approved or funded at the building level.
02 / Project knowledge
Electrification can require coordinated authorization
Calgary’s guidance for certain row-house gang-meter services includes an authorization form signed by the condo board or homeowner association. That process addresses the overall service capacity for added loads. Confirm the current form and applicability with the contractor and City.
EV charging, heat pumps and electric heating should be considered alongside the existing building demand. An approved management design may be an option in some installations; it does not correct damaged equipment or replace required assessments.
03 / Project knowledge
Metering and service changes
Separate utility metering from panel distribution. If the project changes the ENMAX connection, confirm its commercial or residential project classification and required documents. ENMAX’s published intake requires single-line diagrams for commercial services and residential services above 200A.
04 / Project knowledge
Communicate the shutdown and final scope
List affected units, notice responsibilities, essential loads and access needs. Confirm the installation, inspection and reconnection sequence before committing to a date. Retain unit and building records together so future additions can be reviewed consistently.
- Ownership and authorization record.
- Unit equipment and building supply information.
- Metering and connection classification.
- Permit and utility responsibilities.
- Affected-unit notice and closeout records.
Questions we hear
Does replacing my condo panel guarantee room for EV charging?
No. The unit feeder and shared building supply also require review. Confirm capacity and any required board or association authorization.
Is a condo panel project always a utility service upgrade?
No. A distribution change and a supply or metering change should be scoped separately for the actual installation.
