Most electrical projects need a clear authority path before tools or materials are selected. This guide helps organize that path before work starts.
Use this guide before a project starts to identify who controls electrical authority, utility, property, rough-in, final inspection, correction, and reconnection steps.
When to use this guide
- Electrical authority path: a homeowner or contractor needs to know who may apply, who may perform the work, and which permit or notification record controls the job.
- Utility or interconnection path: the work touches service equipment, meter work, reconnects, EVSE, generator, solar, battery, or other utility-facing steps.
- Property approval path: rental, strata, condo, commercial, multi-unit, or business work needs owner or property permission before electrical filing.
Inputs to gather
- Project address, municipality, province or territory, dwelling or business type, and occupancy context.
- Exact scope of electrical work: new wiring, panel work, service work, equipment replacement, repair, or maintenance.
- Who will perform the work: licensed electrical contractor, homeowner where allowed, engineer, utility, or specialty installer.
- Property, strata, condo, landlord, or business approval path when the person requesting work does not control every permission layer.
- Inspection timing needs, especially work that will be concealed before drywall, trench backfill, concrete, ceilings, or finishes.
- Utility-side work, meter changes, service disconnects, reconnects, or interconnection steps that may be separate from electrical inspection.
Project path matrix
| Situation | Verify first | Keep evidence | Stop if |
|---|---|---|---|
| Electrical authority path: a homeowner or contractor needs to know who may apply, who may perform the work, and which permit or notification record controls the job. | Project address, municipality, province or territory, dwelling or business type, and occupancy context. | Scope description written in plain language with affected rooms, equipment, circuits, service, or panels listed. | The work involves service conductors, meter base, utility disconnects, generators, solar, battery systems, or EV load management. |
| Utility or interconnection path: the work touches service equipment, meter work, reconnects, EVSE, generator, solar, battery, or other utility-facing steps. | Exact scope of electrical work: new wiring, panel work, service work, equipment replacement, repair, or maintenance. | Photos of existing panel, service equipment, work area, trench route, equipment nameplates, and labels. | The wiring will be concealed before the authority has confirmed inspection timing. |
| Property approval path: rental, strata, condo, commercial, multi-unit, or business work needs owner or property permission before electrical filing. | Who will perform the work: licensed electrical contractor, homeowner where allowed, engineer, utility, or specialty installer. | Load list or equipment schedule when new loads are added. | The person performing the work is not clearly permitted to do so for that project type and location. |
Working checklist
- Confirm the project branch: Electrical authority path: a homeowner or contractor needs to know who may apply, who may perform the work, and which permit or notification record controls the job.
- Measure or photograph the first hard inputs: Project address, municipality, province or territory, dwelling or business type, and occupancy context. Exact scope of electrical work: new wiring, panel work, service work, equipment replacement, repair, or maintenance.
- Record the decision basis: A simple replacement, a new circuit, a panel change, and a service upgrade can follow different authority paths. Ontario users commonly encounter ESA notification language; British Columbia users commonly encounter Technical Safety BC permit language.
- Keep the handoff package together: Scope description written in plain language with affected rooms, equipment, circuits, service, or panels listed.
- Stop before work proceeds if this applies: The work involves service conductors, meter base, utility disconnects, generators, solar, battery systems, or EV load management.
Workflow
- Find the authority path for the project location before buying major equipment or booking trades.
- Classify the work by what changes: wiring, load, service equipment, utility connection, product type, or occupancy.
- Confirm who is allowed to apply and who is allowed to perform the work in that jurisdiction.
- Separate the sequence into permit or notification filing, rough-in before concealment, trench before backfill, final inspection, corrections, reinspection, and utility reconnection or interconnection.
- Keep permit or notification numbers, inspection notes, photos, revised drawings, correction records, and utility correspondence in one project file.
Decision checkpoints
- A simple replacement, a new circuit, a panel change, and a service upgrade can follow different authority paths.
- A municipal building permit does not automatically settle electrical notification, utility, or product approval requirements.
- A homeowner permission path in one province does not transfer to another province or to rental, strata, commercial, or multi-unit work.
- Utility connection and electrical inspection can be separate approvals with different lead times.
Canada-specific checks
- Ontario users commonly encounter ESA notification language; British Columbia users commonly encounter Technical Safety BC permit language.
- Other provinces, territories, municipalities, and utilities may use different forms, inspection timing, and contractor requirements.
- Use the current Canadian Electrical Code, local authority instructions, utility service rules, and product markings for the actual job.
Project package to keep
- Scope description written in plain language with affected rooms, equipment, circuits, service, or panels listed.
- Photos of existing panel, service equipment, work area, trench route, equipment nameplates, and labels.
- Load list or equipment schedule when new loads are added.
- Permit, notification, inspection, utility, correction, and contractor correspondence saved together.
Stop and get local review
- The work involves service conductors, meter base, utility disconnects, generators, solar, battery systems, or EV load management.
- The wiring will be concealed before the authority has confirmed inspection timing.
- The person performing the work is not clearly permitted to do so for that project type and location.
Questions to settle before work starts
- Which local authority, utility, property authority, product listing, or manufacturer instruction controls this permits and inspection decision?
- Which inputs are measured from the field or nameplate, and which are still assumptions from a quote, drawing, or memory?
- Which part of the work will be concealed, energized, interconnected, or purchased before review if the sequence is not controlled?
- Which single assumption would change the equipment choice, installation path, cost, schedule, or inspection timing?
- Who will keep the final photos, calculator outputs, product documents, permit or utility records, and commissioning notes?
Use the related tools
- Use the Load List kVA and Amps Calculator when the submission needs a simple proposed-load summary.
- Use the Canadian Service Capacity Calculator when new equipment may affect service capacity.
- Use the Panel Capacity Guide before adding EV, heat pump, hot tub, workshop, or similar loads.

Local standards and authority note
Confirm permit, notification, and inspection requirements with the current local authority and utility before work begins.
