Local Permit and Contractor Handoff for London, Ontario
Use the official starting points below to confirm the current permit, inspection and contractor pathway for this Ontario property. The answer can change with the municipality, property type, ownership, project scope and construction stage. A source link is a starting point, not approval for the work.
Bring the Addition Drawings Early
Give the electrician the latest plans, room uses, equipment, lighting goals, panel location, route and future loads. Early coordination can reduce conflicts with structure, insulation, plumbing, HVAC and exterior work.
Sequence Work Before the Envelope Closes

Separate Addition Work From Existing-Home Questions
An addition may expose questions about the existing panel, service, old wiring, access or previous modifications. Ask the electrician to identify those items separately from the new-room scope.

Scope Options to Compare
Depending on the project, a homeowner may be comparing an information-only consultation, a focused inspection, targeted repairs, a panel or service assessment, a room-level renovation scope, a partial rewire, a full project, or a phased plan. Ask the electrician what evidence supports each option, what remains unconfirmed, what access is needed, and how the recommendation affects cost, schedule, permits and future work.
Renovation Scope Decisions to Compare
For London, Ontario in Ontario, use these as planning questions rather than universal code answers. Access, property type, project scope and the authority having jurisdiction can change the next step, so confirm the exact requirements locally.
Design-stage review
Use current drawings, room uses, appliances, equipment and the construction sequence before demolition.
Rough-in planning
Confirm what must be decided, what remains visible and when inspection happens before finishes close access.
Panel and future loads
Include suites, EV charging, heating, garages, appliances and future phases in the first conversation.
Change-order control
Record drawing or equipment changes and ask how revised scope, pricing and schedule will be approved.
How to Compare Electrical Quotes
Compare the written scope, exclusions, access assumptions, equipment assumptions, permit and inspection responsibility, change-order process, schedule, warranty, insurance and close-out documents. A lower number may omit work another quote includes, so ask for clarification before choosing on price alone.
Documents to Keep
Keep permits or notifications, inspection outcomes, invoices, photos of accessible work before finishes close, equipment manuals, panel or service records and the contractor's contact information. These records can help with insurance, resale and future renovations.
Common Mistakes and What Can Go Wrong
Problems usually arise when work is under-scoped, a high-load project is treated as a simple addition, access is closed before inspection, an unlicensed person performs restricted work, equipment assumptions change, or records are not kept. Ask for a written scope and confirm the permit path before corrections become expensive.
Can a Homeowner Do This Work?
Some jurisdictions allow eligible homeowners to perform limited work after obtaining the correct homeowner permit, while other work must be completed by a licensed electrical contractor. Eligibility varies by province, municipality, property type, occupancy and scope. Confirm locally before relying on a homeowner pathway.
