When do I need an electrical inspection in Virginia?

In Virginia you need an electrical inspection in three situations: whenever new or changed wiring goes in, when you are buying a house, and whenever the system shows warning signs or has gone decades without a look. The building code requires the first; the other two are how you find problems before they find you.

Required: new or changed wiring

Virginia's Uniform Statewide Building Code says a permit must be obtained before work starts on electric wiring.^[1] There is one allowance for urgent jobs: for emergency construction, alterations or equipment replacement the application can be filed by the end of the first working day after the work starts.^[1]

Once there is a permit, the building department inspects. The code's minimum inspections include inspection of electrical, mechanical and plumbing materials, equipment, and systems prior to concealment,^[2] plus a final inspection, and work is not considered in compliance until the inspecting authority approves it.^[2] The code does add that where the construction cost is under $2,500 the inspection may be waived at the building department's discretion.^[2]

The code does not list jobs one by one. Examples of work that usually involves installing or altering wiring, and so usually needs a permit and inspection, include:

• A new circuit, outlet, switch or fixture location.
• A new or replacement panel, or a service upgrade.
• A circuit for a range, dryer, heat pump, hot tub or EV charger.
• Rewiring part or all of the house.
• Wiring in a basement finish, addition or remodel.

What is exempt

The code does not require a permit for replacing general use snap switches, dimmer and control switches, 125-volt 15- or 20-amp receptacles, light fixtures and ceiling fans,^[1] in the code's Groups R-3, R-4 and R-5, and in Group R-2 where serving a single dwelling unit.^[1] That covers like-for-like swaps in a typical house or apartment, not moving or adding anything.

If you want an exempt job on the record anyway, the code allows it: if an owner asks for a permit for exempt work, the permit is issued and the inspections are required.^[1]

Advised: when you buy a house

Under the Residential Property Disclosure Act, the seller makes no representations or warranties about the condition of the property, and buyers are advised to exercise whatever due diligence they deem necessary, including obtaining a home inspection.^[3]

Only a licensed home inspector may perform a home inspection,^[4] and a home inspection on a new residential structure can only be done by an inspector with the NRS specialty.^[4] The home inspection covers the electrical system along with everything else; see what a home electrical inspection includes. When the report flags the panel, wiring type or missing protection, book a licensed electrician to evaluate it before your inspection contingency runs out. For older houses, read whether knob-and-tube wiring is a problem when buying.

Advised: warning signs or a long gap

The U.S. Consumer Product Safety Commission gives a simple rule of thumb. If your last inspection was 40 or more years ago, an inspection is overdue; between 10 and 40 years ago, an inspection is advisable, especially if large electrical loads have been added or warning signs are present.^[8] If you live in an area not served by state or local electrical inspectors, so no record will be found on the panel, use the age of the house as the guide.^[8]

The warning signs on its list are worth knowing: fuses or breakers that blow or trip often, dim or flickering lights, sparks, sizzling or buzzing, switch plates or outlet covers that are hot or discoloured, a smell of hot insulation, and any shock, even a mild tingle.^[8] Any of those is a reason to call an electrician now, not at the next convenient time.

Two other moments to book an evaluation:

• Aluminum wiring. The CPSC notes that cables installed between 1965 and the mid 1970s may contain aluminum wiring.^[9] Houses built or added on in that period are worth checking.
• Before a big new load. An EV charger, heat pump or hot tub adds load to a panel that may already be full. An electrician can check capacity before you buy the equipment.

When to call a licensed pro

Anyone you hire for the jobs above must be licensed. Virginia law defines a tradesman as anyone who works "for the general public for compensation" in the electrical, plumbing or HVAC trades,^[6] and no individual may do that work unless licensed.^[5] The electrician you hire should handle the permit. The Board for Contractors is blunt about it: "Anyone who tries to talk you into getting your own building permit is not doing you any favors."^[7]

Keep the inspection in your payment terms. The Board advises, "Do not allow work to start until the contractor gives you copies of the officially issued permit(s), as required."^[7] And before the last payment: "Make sure all required building inspections have been completed to the satisfaction of the proper authorities."^[7] You can check the electrician's licence on DPOR's record first.
