Section 01
Why the electrical file matters more in a house that has grown
A house that has been extended, finished below grade, given a detached shop or fitted with a secondary suite has usually had several separate electrical projects, each with its own contractor and its own file. Read together, those files describe how the service has been loaded over time and where later work depended on earlier work.
This is the difference between a general reassurance and an evidenced history. A buyer of a distinctive property is not asking whether the lights work; they are asking whether the additions they intend can be supported and whether the existing work went through a permitted, inspected process.
Section 02
Documented: what the permit record contains
The City's residential electrical permit page sets out when a permit is required and who may apply, including the distinction between work performed by a licensed contractor and work an owner may apply for on their own residence. The resulting record shows the permit, the described scope, and inspections requested and recorded against it.
Where a record shows a completed inspection, that is a fact about the inspection. Where a permit remains open, that too is a fact, and an open permit on a property being sold is an item to resolve before possession rather than a matter of interpretation.
Section 03
Not documented: capacity, condition and workmanship
The permit file does not state how much of the electrical service remains available for future load. It does not report the condition of the panel, the busbar, breakers, service conductors, bonding or grounding. It does not identify obsolete or recalled equipment, and it does not describe workmanship. The City states its residential inspections are a point-in-time audit against minimum safety standards and differ from third-party home inspections.
It also cannot tell you whether the installation suits the way you will use the house. A car charger, a shop, a pool, a heat pump or a kitchen rebuild each place demands on the service that must be assessed against the actual installation by a licensed contractor.
Available service capacity is property-specific and is assessed by a licensed electrical contractor, never inferred from a permit record or a construction date.
Section 04
Reading the file without over-reading it
Work chronologically. Note each permit's date, described scope and inspection outcome, then compare that list against what is physically visible in the house — a suite, a shop, exterior lighting, a hot tub circuit, a charger. Where the house shows something the file does not, write it down as an open question for the seller and, if it matters, for a contractor.
Resist two temptations. Do not treat a missing record as proof that work was unpermitted; the City's records search gives no guarantee that records exist. And do not treat a closed permit as an assurance of quality, because that is not what an inspection records.
Section 05
The evidence request list
Request: the full electrical permit history for the address; inspection records and status for each permit, including any that remain open; the contractor names on each permit; any electrical drawings or load calculations the owner holds; documentation for major additions such as a suite panel, shop subpanel, charger circuit or standby generator; and a written seller statement about electrical work they know of without a permit record.
Then commission an assessment by a licensed electrical contractor covering the service size, panel condition and available capacity for your intended use. Ask for that assessment in writing with a scope and limitations statement, because a verbal reassurance is not evidence and cannot be handed to the next owner.
Section 06
The owner's electrical handover pack
A well-kept pack holds the permit and inspection history, contractor invoices and warranty documents, the panel schedule as it actually is rather than as it was originally labelled, photographs of the panel interior taken during service work, and the written contractor assessment with its date.
For a property with a suite, a shop, extensive landscape lighting or automation, add the as-built documentation for those subsystems. This is the material a buyer's advisor asks for, and its absence is what turns an ordinary enquiry into a lengthy condition period.
Section 07
Escalation triggers
Engage a licensed electrical contractor before purchase where the house has a suite, a shop, a pool or extensive additions; where the panel is unfamiliar or crowded; or where you intend to add significant load. Engage them immediately, rather than at leisure, where there are signs of overheating, repeated nuisance tripping or amateur alterations.
Where a permit is open, resolve it through the permit holder and the City before possession. Where a dispute about undocumented work arises in a transaction, that is a matter for your representative and, if needed, a lawyer. Nothing on this page is an electrical, engineering or legal opinion about any property.
This page describes records. It does not assess any installation and reaches no conclusion about safety at any address.
