Hillsboro OR Whole-Home Rewiring Costs (2025)

Estimated Read Time: 12 minutes

Wondering what the cost to rewire a house looks like in 2025? You are not alone. Older wiring, tripping breakers, or a planned remodel raise smart safety questions. In this guide, we break down real‑world price ranges, the factors that move your estimate up or down, and when a panel upgrade is smart. You will also learn how Portland‑area permits, inspections, and code updates shape the final number.

2025 Average Cost to Rewire a House

Rewiring is a safety and capacity upgrade, not just a cosmetic change. In 2025, typical whole‑home rewiring in the Portland metro runs from $8,500 to $22,000 for most single‑family homes, with larger, complex projects rising to $30,000+. Condos or small bungalows can land lower when access is easy. Knob‑and‑tube or aluminum branch‑circuit homes usually lean higher because of added safety steps and patching.

Where your home lands in that range depends on square footage, access to walls and attic, the electrical panel, and code items that must be updated during the same project. The right partner will walk every circuit, confirm scope, and produce a transparent line‑item proposal.

What Drives the Price Up or Down

Several factors determine how much you pay. Focus on these early so your quote is accurate.

1. Home size and number of circuits • More rooms and dedicated appliance circuits mean more labor and materials.

2. Access conditions • Open framing during a remodel costs less than fishing new cable through finished walls and plaster. • Crawlspace, attic, and multi‑story access change labor hours.

3. Panel capacity and condition • Many older homes have 60A–100A service. Modern homes often need 200A to support HVAC, EV charging, and kitchens. If the panel is outdated or full, a service upgrade is smart to do at the same time.

4. Code upgrades required • 2023 NEC adoption in the region drives requirements like AFCI protection on many circuits, GFCI in wet areas, and tamper‑resistant receptacles in living spaces. Smoke and CO detector placements are also brought up to code during significant electrical work.

5. Occupied vs. vacant • Working in an occupied home requires staging, dust protection, and daily cleanup, which adds time.

6. Finishes and patching • Fishing wires carefully can limit drywall cuts. Homes with lath and plaster often need more patching.

7. Special conditions • Aluminum branch circuits from about 1965–1973 need special terminations or replacement. • Knob‑and‑tube often lacks grounding and safe junctions. Replacement takes planning.

Line‑Item Cost Breakdown

While every home is different, here is how costs typically stack up in 2025 in the Portland area:

1. New branch‑circuit wiring and device replacement: $3,500–$11,000 • Copper NM‑B or MC cable, new grounded circuits, receptacles, and switches.

2. Panel and service upgrade: $2,800–$6,500 • New 200A panel, meter base as needed, service mast, grounding and bonding, labeling.

3. AFCI/GFCI protection: $400–$1,200 • Combination AFCI or dual‑function breakers where required by code.

4. Specialty circuits: $400–$2,000 • Dedicated lines for range, dryer, microwave, disposal, dishwasher, mini‑split, or EV charger.

5. Smoke and CO detectors: $250–$900 • Interconnected, correctly located per code.

6. Low‑voltage and add‑ons: $200–$1,500 • Doorbell transformer, data runs, surge protection.

7. Drywall patching and paint: $500–$3,000 • Varies with access, plaster vs. drywall, and homeowner preferences.

8. Permits and inspections: $250–$1,200 • City or county permits and inspections from the Authority Having Jurisdiction.

9. Project management and final inspection: $300–$900 • Documentation, circuit mapping, homeowner walkthrough.

These ranges reflect typical projects. Historical homes, high‑end finishes, or tight access can land higher. Combining a rewire with a remodel can reduce patching costs.

Whole‑Home vs. Partial Rewiring

A full rewire replaces old branch circuits throughout. A partial rewire targets high‑risk areas first.

• When a full rewire makes sense

  1. Presence of knob‑and‑tube or cloth‑insulated wiring throughout.
  2. Frequent tripping, warm outlets, or brittle insulation across many rooms.
  3. Upcoming kitchen, bath, or HVAC upgrades that will add load.

• When a partial approach can work

  1. Isolated circuits with damage or aluminum splices.
  2. Budget or timing constraints during a phased remodel.

• Savings potential • Partial rewires can save 25–50 percent versus a full project, but may require repeat permitting and patching later. We will map a phased plan so each step builds toward a fully modern system.

Timeline: What to Expect

Most whole‑home rewires take 3–10 working days, depending on size and access. A clear plan prevents surprises.

1. Home assessment and load calculation • We evaluate panel capacity, grounding, and every branch circuit. We also note smoke/CO needs and any aluminum or knob‑and‑tube.

2. Permit filing and scheduling • We help with the application process and schedule inspections with your city or county.

3. Rough‑in work • Pull new cable, set new boxes, and prepare AFCI/GFCI protection. If a panel upgrade is planned, we coordinate utility cutover timing.

4. Device install and labeling • Receptacles, switches, and fixtures are set. Circuits are labeled for easy future service.

5. Final inspection and walkthrough • We complete an end‑of‑service inspection to verify proper operation and code compliance, then walk you through any warranty and maintenance items.

Signs Your Home May Need Rewiring

• Two‑prong outlets with no ground in living spaces
• Repeated breaker trips or fuses blowing
• Warm or discolored outlets and switches
• Flickering lights not tied to a single fixture
• Aluminum or cloth‑insulated wiring visible in attic or basement
• Renovations planned that will add major appliances or HVAC

If you notice burning odors, arcing, or smoke, cut power to the circuit and call for emergency service.

Panel Upgrades: The Right Time to Bundle

We generally recommend changing everything at the same time so your home is fully upgraded and ready to handle modern appliances and power needs. Many older homes run on 60A–100A service, while 200A is the current norm for homes with heat pumps, induction ranges, and EV charging. Upgrading the service during a rewire prevents duplicated labor and future outages. It also creates room for AFCI and GFCI breakers and whole‑home surge protection.

Special Cases: Aluminum and Knob‑and‑Tube

• Aluminum branch circuits (about 1965–1973)

  1. Issues include loose terminations and higher expansion rates.
  2. Safe remediation options include complete replacement or approved connectors and CO/ALR rated devices. Many homeowners choose full replacement during a rewire.

• Knob‑and‑tube

  1. Often lacks grounding and has open splices hidden by later insulation.
  2. Replacement adds safety and makes AFCI and GFCI protection straightforward.

Both conditions tend to increase cost and timeline. A thorough evaluation confirms the best path.

Permits, Codes, and Inspections in the Portland Metro

Portland, Vancouver, and nearby jurisdictions enforce modern electrical codes. Expect permits and inspections on full rewires and most partials.

• Code milestones that affect scope

  1. Arc‑Fault Circuit‑Interrupter protection is required on many habitable area circuits under modern NEC editions.
  2. Ground‑Fault protection is required in kitchens, baths, garages, and outdoor areas.
  3. Tamper‑resistant receptacles are standard in most living areas.
  4. Interconnected smoke and CO detectors placed per current rules.

• Inspection process

  1. Rough‑in inspection verifies cable routing, box fill, support, and bonding.
  2. Final inspection confirms device installation, labeling, and function.

We handle permits, coordinate inspections with the Authority Having Jurisdiction, and keep you informed at each step.

Local Insight: What We See in Portland‑Area Homes

Homes in Portland, Beaverton, and Hillsboro often have finished basements that limit access, so we plan routes carefully to reduce drywall impact. In Vancouver and Camas, many 1990s homes are ready for 200A panels to support heat pumps and EVs. In Lake Oswego and West Linn, plaster walls and detailed trim favor careful fishing with minimal patching. This local experience informs realistic quotes and smoother projects.

Quick Cost Scenarios

• 1,200 sq. ft. bungalow, good access, 100A panel retained: $8,500–$12,000
• 1,800 sq. ft. mid‑century, moderate patching, 200A upgrade: $14,000–$20,000
• 2,500 sq. ft. two‑story with plaster, panel and several new dedicated circuits: $20,000–$30,000+

These are estimates. A no‑pressure on‑site assessment is the right next step.

What Homeowners Are Saying

"Matt came over to work on our house and our neighbor's house. He sorted out the crazy wiring in our neighbor's kitchen, then came over to our house to assess our projects. Matt returned the next day with Bryan to add a second outlet in our bathroom and button up a dead outlet in the dining room. They were both very pleasant and friendly and did an excellent job! We've been very happy with Sky (they take care of our heating/AC, too) and will call them again for any issues we have in the future."
–Matt Customer., Portland

"Our old AC unit was 23 years old and failing. We had Michael Dominguez design the system for our new dual stage AC. He and the Install team were pleasant and showed expert knowledge. We had a wiring glitch the first day, but it was fixed the next morning. Everyone was professional and friendly. I highly recommend Sky and their great service."
–Michael D., Vancouver

Frequently Asked Questions

How much does it cost to rewire a 1,500 sq. ft. house in 2025?

Most Portland‑area homes of this size land between $12,000 and $18,000, depending on access, panel upgrades, and code items like AFCI/GFCI.

Do I need a panel upgrade to rewire my house?

Not always. If your panel is safe and has capacity, we can reuse it. Many homes upgrade to 200A to support EVs, heat pumps, and kitchen loads.

Can I live in my home during a rewire?

Yes, in most cases. We stage the work, provide temporary power as needed, and keep daily areas safe. Vacant homes can shorten the timeline.

Is a permit required for a whole‑home rewire?

Yes. Your city or county issues permits and inspects rough‑in and final work. We handle the application and schedule inspections for you.

What if my home has aluminum wiring?

We will evaluate whether replacement or approved remediation is best. Aluminum tends to add cost and time but can be addressed safely by a licensed pro.
