Rewire cost breakdown (Reno, 2026)
| Scope | Range | Notes |
|---|---|---|
| Basic 3-bedroom home, accessible walls/attic | $2,500–$6,000 | HomeGuide 2026 baseline. Assumes open attic/crawl access and no panel change. |
| Per-square-foot estimating basis | $5–$17 / sq ft | Low end: open access, few fixtures. High end: plaster/finished walls, slab, many circuits. |
| Worked example — 1,500 sq ft | $7,500–$25,500 | Arithmetic only: 1,500 × $5–$17. Not a separate source. |
| Panel upgrade, if needed at the same time | $850–$2,500 nat'l · $2,600–$3,600 Reno | Common on a rewire — the old panel usually can't take the new circuit count. See the panel guide. |
| Drywall/plaster repair and paint | Separate trade — ask | Often NOT in the electrician's bid. Confirm who patches the access holes. |
| Permit + inspection | $50–$200 + $100–$200 | Required. ONE Regional portal (onenv.us); rough-in and final inspections. |
Methodology. The $2,500–$6,000 and $5–$17/sq ft figures are HomeGuide's 2026 electrical work pricing guide and cost-per-hour data (February 2026, national contractor-estimate data). The 1,500 sq ft row is arithmetic on that rate, shown so you can do the same for your square footage — it is not a separately sourced figure. No Reno-area electrician publishes rewire pricing we could cross-check, so we don't adjust the national numbers; given that Reno panel work runs above national (see the panel guide), treat the top of the range as realistic here. Recheck before republishing.
Signs a Reno home needs rewiring, not just a panel
- Knob-and-tube wiring. Ceramic knobs and tubes in the attic or basement, cloth-insulated conductors, no ground. Found in the oldest Reno and Sparks housing; it wasn't designed for today's loads and can't legally be extended.
- Aluminum branch wiring (roughly 1965–1973 construction). Dull silver conductors at outlets and switches. It expands and contracts more than copper, loosening connections over time. A full rewire is one fix; approved AlumiConn/COPALUM connectors at every device is the cheaper remediation many electricians recommend first.
- Two-prong (ungrounded) outlets throughout. One or two can be handled with GFCI protection; a whole house of them means the branch circuits have no ground conductor.
- Brittle, cracked, or rodent-damaged insulation visible in the attic or crawl space.
- Recurring symptoms across rooms — flickering, warm switch plates, a persistent faint burning smell, outlets that spark when plugging in — after a panel and device check has ruled out the easy causes.
- A major remodel. If walls are coming open anyway, rewiring costs a fraction of what it does as a standalone job.
What a complete rewire includes — and what it usually doesn't
A bid in the ranges above should include:
- Permit through ONE Regional Licensing & Permits (onenv.us), a rough-in inspection before walls are closed, and a final inspection.
- New copper NM cable (or conduit where required) to every outlet, switch, and fixture; new circuits laid out to the current code — Washoe County adopted the 2023 National Electrical Code effective July 1, 2025 (compliance required from January 1, 2026), with the 2024 Northern Nevada Amendments.
- New devices: tamper-resistant receptacles, GFCI where required (kitchens, baths, garage, outdoors, laundry), AFCI protection on the circuits the code requires.
- Grounding and bonding brought to code.
- Smoke and CO alarm wiring where the code requires interconnected, hardwired units.
- Cutting and, in most bids, rough patching of access holes. Finish drywall, texture, and paint are usually a separate trade — confirm in writing who does what.
Usually not included unless quoted: a panel upgrade (see the panel upgrade guide), new fixtures or fans beyond the boxes for them, low-voltage (data, TV, security), and finish repair. Ask for each as a line item so two bids are comparable.
What moves the price
- Access. Attic and crawl space access is the single biggest factor. A slab-on-grade single story with a low attic is fine; a two-story with no attic access over the first floor is where fishing cable becomes opening walls.
- Wall type. Plaster and lath is slower and more fragile than drywall.
- Circuit count. Today's code wants more circuits than a 1960s house had — dedicated kitchen, bath, laundry, garage circuits. More circuits, more cable, more time.
- Occupied vs. empty. Working around furniture, keeping some circuits live each night, and protecting finishes all add labor. If you can move out for the week, say so when you get bids.
- Timing with other work. Bundling with a remodel or a panel upgrade saves duplicated setup, permits, and inspection visits.
Hiring for a rewire
A rewire is the one residential electrical job where the NSCB record's monetary limit can matter — confirm the license limit covers your contract value. Check the C-2 subclass (C-2a or C-2f), get the permit and both inspections as line items, and remember Nevada caps the residential deposit at the lesser of $1,000 or 10% of the contract (NRS 624.970) — on a $12,000 rewire the lawful maximum is $1,000. Progress payments tied to the rough-in and final inspections are the normal structure. The how-to-hire guide has the full lookup and the questions to ask.
Rewiring questions
How much does it cost to rewire a house in Reno?
As of September 2026, rewiring a basic three-bedroom home in Reno, NV costs $2,500–$6,000 when walls and attic are accessible, and electricians estimate larger or harder jobs at $5–$17 per square foot — roughly $7,500–$25,500 for a 1,500 sq ft home. Add a panel upgrade ($2,600–$3,600 at Reno-quoted rates) if the old panel can't take the new circuits.
Do I actually need a full rewire, or just a panel upgrade?
A panel upgrade fixes capacity at the panel; a rewire fixes the wiring in the walls. If your problems are all "not enough power" (tripping under load, no slots), the panel guide is the right page. If they are "the wiring itself is unsafe" — knob-and-tube, ungrounded two-prong outlets everywhere, aluminum branch circuits, brittle or damaged insulation — that is a rewire question. Many older homes end up needing both.
How long does a whole-house rewire take?
Typically three to ten working days for a single-family home, depending on size and access. Expect rooms to be disrupted in sequence, power off to sections of the house during the day, and a rough-in inspection before walls are closed up, then a final inspection.
Can a house be rewired without tearing out all the drywall?
Usually, yes. Electricians fish new cable through walls from the attic or crawl space and cut small access holes at strategic points rather than opening every wall. Plaster walls, slab foundations, and two-story homes with no attic access are the cases where more opening is unavoidable — and where the per-square-foot price climbs toward the top of the range.
Will my insurance company require a rewire?
Some insurers decline or surcharge homes with knob-and-tube or aluminum branch wiring, or with certain recalled panel brands, and may require remediation at renewal or when you buy. Ask your agent before assuming; a written electrician's inspection report is usually what they want to see.
