Quick answer
An electrical inspection is an examination of a building’s wiring and electrical equipment to confirm it is safe and meets the adopted electrical code, done either by a government inspector to close a permit or by a qualified electrician as a condition or safety check.
Permit inspections happen at set stages of a job. Other inspections, such as before buying a home, are voluntary and look at the whole system.
Quick facts
The key facts about Electrical Inspection, with sources:
- Permit inspections
- Rough-in before walls close, then final 1
- When to request (Washington)
- Before covering; within 3 business days of finishing or 1 after energizing 1
- Who inspects
- State or local inspectors; some cities run their own programs 2
- Code used
- The edition adopted where the permit is filed 3
- Virtual option
- Minnesota DLI offers scheduled virtual electrical inspections 3
- Penalty for skipping
- Civil penalties; power may be disconnected (Washington) 1
Key takeaways
- There are two kinds: permit inspections by a government inspector, and condition inspections by an electrician.
- Permit inspections happen at rough-in, before walls close, and at final.
- The inspector checks the work against the code edition your area adopted.
- Failing is common and fixable; the inspector lists corrections and returns.
- For an older home or before a purchase, a whole-house condition inspection finds hazards permits never covered.
What an electrical inspection is
The word covers two different visits. A permit inspection is part of the legal process for new work. A state or city inspector looks at the work you had permitted and approves it or lists what must change.
A condition inspection is a review of a whole house’s electrical system, often before a purchase, after a storm, or in an older home. It is done by a licensed electrician you hire, and it reports on safety and age rather than passing or failing a permit.
This page defines both. To book one, see our electrical inspection service.
How a permit inspection works
Once a permit is issued, the contractor or owner requests each inspection. Washington requires you to request one before covering any electrical work, and no later than three business days after finishing or one business day after any part is energized, whichever is first 1.
The inspector visits, checks the work, and either signs off or writes a correction notice. After corrections, a re-inspection follows. When the final passes, the permit closes. In Minnesota you can also schedule a virtual inspection through the state 3.

Types of electrical inspection
| Type | Who does it | When | Outcome |
|---|---|---|---|
| Rough-in (permit) | Government inspector | Before walls or ceilings close | Pass or corrections |
| Final (permit) | Government inspector | Work complete | Permit closed |
| Service inspection | Government inspector | New or upgraded service | Release to the utility |
| Home-purchase inspection | Electrician you hire | Before buying | Condition report |
| Safety or insurance inspection | Electrician you hire | Older home, after damage, insurer request | Condition report and repair list |
Example: what a final inspection on a new panel looks at
| Item | What the inspector checks | Code note |
|---|---|---|
| Panel label | Circuits identified clearly | 2026 NEC 408.10(F): labels on the front of the enclosure |
| Emergency disconnect | Outdoor, readily accessible, labeled | 2026 NEC 230.70 for one- and two-family homes |
| GFCI and AFCI | Protection where required | NEC 210.8 and 210.12 (2023 and 2026 editions) |
| Grounding electrode | Rod depth and connections | 2026 NEC 250.53(A)(4): driven vertically to 8 ft unless not feasible |
| Working space | Clear space in front of the panel | NEC 110.26 (2023 and 2026 editions) |
| Breakers and wire | Sizes match; no doubled-up conductors where not allowed | 2026 NEC 110.3(B): maker instructions cannot be less strict than the code |
Where inspection records show up
Passed inspections are recorded against the permit. Buyers, lenders and insurers may check them. Washington warns that missing permits and inspections can affect financing, sale and insurance claims 1.
Condition inspections produce a private report. Keep it with your house records and share it with an electrician when you get repair quotes.
Permit inspection
- Done by a government inspector
- Checks only the permitted work
- Pass or fail against the adopted code
- Required by law for permitted jobs
Condition inspection
- Done by an electrician you hire
- Looks at the whole system
- Report of hazards, age and priorities
- Voluntary; often before purchase

What a whole-house condition inspection usually covers
Scope varies by electrician, so ask for it in writing. A typical visit looks at:
- Service and meter: the drop or lateral, meter base, and the main disconnect.
- Panel: brand and age, signs of heat, breaker sizes against wire sizes, labeling, and clear working space.
- Grounding and bonding: the grounding electrode connection and bonding of water and gas piping.
- Protection: GFCI and AFCI where today’s code would expect them, tested with the TEST button or a tester.
- Branch wiring you can see: wiring type (such as knob-and-tube or aluminum branch wiring), splices outside boxes, and damaged cable in attics and basements.
- Devices: a sample of outlets checked for polarity and grounding, and any warm or loose ones.
- Large loads: dryer, range, HVAC and any EV charger circuits, compared with their nameplates.
New work vs existing wiring
Permit inspectors judge new work against the code in force now. They do not usually make you upgrade the rest of the house to today’s code, unless what they see is an immediate hazard or local rules say otherwise.
Condition inspections work the other way. They compare the whole house with current practice to show what is dated, and then rank it. A missing GFCI in an old bathroom may be legal as built but still worth fixing. Our guides on knob-and-tube wiring and aluminum wiring explain two common findings.
Benefits and limits
What it does well
- Independent check of safety-critical work.
- Catches hidden problems before walls close.
- Creates a record that helps resale.
- Condition inspections find old hazards like worn panels or aluminum branch wiring.
Where it falls short
- Inspectors see what is visible on the day.
- Scheduling can delay a job.
- Permit inspections do not look at unrelated parts of the house.
- A pass is not a guarantee of future performance.
What inspections miss
Wiring inside finished walls cannot be seen in a condition inspection without opening walls. Inspectors note what they can access and flag what they could not.
Permit inspectors check code minimums. A design that meets code may still be inconvenient, like too few kitchen circuits for how you cook.
They also cannot judge future loads. A panel that passes today may have no room for the EV charger or heat pump you add in three years. If you have plans, tell the electrician so the report covers capacity as well as safety.
What drives inspection cost
We do not list fees. Permit inspection fees are part of the permit; condition inspections are priced by the electrician. See cost guides.
- House size and number of panels.
- Age: older homes take longer.
- Re-inspections after failed items.
- Access: attics, crawl spaces, finished basements.
- Testing included, such as GFCI and AFCI checks.
How to prepare for a permit inspection
- Confirm the inspection is booked within the required window 1.
- Clear access to the panel, attic and work areas.
- Keep the permit card visible.
- Have the electrician present if the office expects it.
- Fix listed corrections and book the re-inspection.
How often to inspect an existing home
No national rule sets a schedule for homeowners. Common triggers are buying a home, a major remodel, adding large loads, flood or fire damage, and signs like flickering lights or warm outlets.
Between inspections, press TEST on GFCI outlets monthly and keep the panel directory current. Our electrical safety check walks through owner-safe checks.
Signs you should get an inspection
- Breakers that trip often or a main breaker that trips.
- Warm or discolored outlets and switches.
- Burning smell with no clear source.
- Older panels known for problems; see hazard-era panels research.
- Unpermitted additions or DIY wiring by a past owner.
Safety
Who sets inspection rules
Inspections are run by the authority having jurisdiction. In Washington, L&I inspects most jobs; cities with their own programs and Tacoma Power’s area inspect locally 2. Penalties apply for skipping required inspections, and power can be disconnected for non-compliance 1.
Inspectors apply the adopted NEC edition. Minnesota inspects permits filed from 17 August 2026 to the 2026 NEC 3. NFPA offers free read-only access to the code text 5.

Common misconceptions
- Myth A home inspector’s report covers the electrical system fully.
- Reality General home inspections are visual surveys; an electrician goes deeper.
- Myth A failed inspection means bad work.
- Reality Many failures are small fixes like a missing label.
- Myth You can close walls and inspect later.
- Reality Washington requires inspection before covering 1.
Which inspection do you need?
- If you are having work done, your electrician books the permit inspections.
- If you are buying an older home, add an electrician’s condition inspection.
- If you plan an EV charger or heat pump, an inspection can show whether the panel is ready.
- Next step: find a local electrician.
Before you buy
Ask the seller for permit records on any panel, service or addition. Missing records are a reason to get an electrician’s inspection before closing.
Questions about Electrical Inspection
What do electrical inspectors look for?
Electrical inspectors check that the permitted work meets the adopted code: correct wire and breaker sizes, boxes and connections, grounding and bonding, GFCI and AFCI protection, panel labeling and working space. On new services they also check the disconnect, meter base and grounding electrode.
When is a rough-in electrical inspection done?
After wiring and boxes are in but before insulation and drywall cover them. Washington requires you to request inspection before covering any electrical work. Covering early can mean opening walls later.
How long does an electrical inspection take?
A permit inspection on a small job can take minutes; a whole-house condition inspection can take hours, depending on size and age. Scheduling the visit often takes longer than the inspection itself.
What happens if I fail an electrical inspection?
The inspector lists corrections. Your electrician fixes them and you book a re-inspection. The permit stays open until the work passes. Most failures are fixable items rather than major defects.
Do I need an electrical inspection when buying a house?
A buyer’s electrical inspection is not legally required in most places, but it is wise for older homes, homes with additions, or when the general home inspection flags electrical issues. An electrician’s inspection looks deeper than a general home inspection.
Who does electrical inspections?
Permit inspections are done by state or local inspectors. In Washington, L&I inspects most jobs, but some cities run their own programs. Condition inspections are done by licensed electricians you hire.
Can electrical inspections be done virtually?
In some places. Minnesota’s Department of Labor and Industry offers scheduled virtual electrical inspections. Ask your local office whether it accepts photos or video for your type of job.
What is the difference between an electrical inspection and a home inspection?
A general home inspection is a visual survey of the whole house, and electrical is one item among many. An electrical inspection is done by an electrician or code inspector and goes deeper: testing protection devices, checking breaker and wire sizes, and opening the panel cover safely. Home inspectors often refer concerns to an electrician.
How often should a home’s wiring be inspected?
There is no national schedule for homes. Get one when buying, after major remodels, before adding big loads like an EV charger or heat pump, after flood or fire damage, or when you see warning signs.
Is an electrical inspection required for an EV charger?
Usually, because the charger adds a permitted circuit. The inspector checks the breaker and wire against the charger’s rating and the continuous-load rule, and confirms the equipment is listed.
