For a new build in the Portland metro, the electrical package runs about $4 to $9 per square foot for a standard home, and up to roughly $12 per square foot for high-end or heavily automated builds. That figure covers labor, rough-in materials, standard devices, the main panel, the service entrance, and the permit. Decorative light fixtures are usually bought separately by the owner or designer, so they are not in that number.
Two things move you within that range: the size and complexity of the home, and how much capacity and code-required gear the service needs. And in 2026, there is a third factor that has nothing to do with the wiring itself: lead times on electrical equipment. Order it late and it can blow up your whole schedule. Here is the full picture.
What does new construction electrical cost in Portland?
A single price is misleading because device count, service size, and the length of the utility run all swing it. The ranges below reflect 2026 Portland-metro pricing and cover labor, rough-in material, standard devices, the panel, the service entrance, and the permit. They exclude decorative fixtures (usually owner-supplied) and any heavy site trenching.
| Project type | Size | Rough $/SF | Estimated electrical total |
|---|---|---|---|
| Spec single-family | ~1,800 SF | $4 – $6 | $7,000 – $12,000 |
| Custom / high-end | ~3,000 SF | $8 – $12 | $24,000 – $40,000 |
| Detached ADU | ~700 SF | $10 – $15 | $10,000 – $16,000 |
| Duplex (dual 200A) | ~2,400 SF | $6 – $9 | $18,000 – $28,000 |
Notice the ADU. A 700-square-foot unit costs almost as much per square foot as a luxury custom home, because it still needs the full infrastructure of a house (its own subpanel or meter, a kitchen, bathroom GFCIs, HVAC feeds) plus a trench to run the feeder from the main building. You lose the economies of scale. A custom home climbs for the opposite reason: high device density, lighting control systems, a 400-amp service for EV chargers and electric appliances, and complex routing through vaulted ceilings and glass.

The four phases of a new-build electrical scope
Unlike a remodel, new construction electrical is sequenced tightly against framing, plumbing, and HVAC. It happens in four phases, and a slip in any one cascades into the rest of the build:
- Temporary power: a temp pole, meter, and panel so the site has power for framing and tools, coordinated with PGE and inspected before it is energized.
- Service entrance: the permanent underground (or overhead) service, meter base, and main disconnect on the exterior. For duplexes and cottage clusters, this means a ganged meter pack splitting the feed between units.
- Rough-in: the heavy-labor phase. All branch wiring, device boxes, the panel, grounding, and low-voltage (data, coax, smart-home) go in after framing and before insulation and drywall. Ends with the rough-in inspection.
- Trim-out: after drywall and paint, the wiring becomes a live system, receptacles, switches, fixtures, breakers, and interconnected smoke and CO alarms, then the final inspection that clears the way for occupancy.
The code requirements driving your 2026 budget
Oregon builds to the Oregon Electrical Specialty Code (OESC), which is the 2023 National Electrical Code with state amendments. Several of its requirements directly add cost to a new home, and they are not optional:
- 200-amp service is the new floor. Heat pumps, induction ranges, heat pump water heaters, and EV charging have made 100-amp service obsolete for a new build. Larger homes increasingly go 400-amp.
- No outdoor emergency disconnect required (NEC 230.85). The 2023 code added this, but Oregon did not adopt it, so a new home here does not need an exterior emergency disconnect. Building across the river in Vancouver or Camas? Washington does require it, and it adds hardware and labor there.
- Surge protection is optional in Oregon (NEC 230.67). The 2023 code requires a surge protective device at the service of a new dwelling, but Oregon did not adopt that section either. It is worth installing to protect appliances and electronics, but in Oregon it is your call, not a mandate. In Washington it is required.
- AFCI and GFCI everywhere. Nearly every living-space circuit needs arc-fault protection, and GFCI coverage keeps expanding. These breakers cost several times more than standard ones, which adds up across a full panel.
- Tamper-resistant receptacles and hardwired, interconnected smoke and CO alarms throughout the home.
New Oregon homes must be wired to support at least one Level 2 EV charger, meaning a dedicated 240-volt circuit run to the garage or driveway so a charger can be added later without opening walls. Larger multifamily buildings (5+ units) must make a share of spaces EV-capable. New homes also need solar-ready provisions, a conduit pathway to the roof and reserved panel space, so panels can be added down the road.
Permits, inspections, and PGE
Electrical work in Oregon must be done by a contractor holding both a CCB registration and a Building Codes Division electrical license. Permit fees vary by jurisdiction (City of Portland through Portland Permitting & Development, plus Multnomah, Washington, and Clackamas counties), and Oregon adds a flat 12% state surcharge on top of every permit. Confirm current fees with your jurisdiction, since they change yearly.
The inspection sequence is rigid: temporary power, underground trench, rough-in, service/meter, and final. Each one is a gate, and a failed inspection means a re-inspection fee and a schedule hit.
This is the single biggest schedule risk in 2026. Demand from data centers has stretched lead times on engineered electrical equipment, transformers, switchgear, and large meter packs can run many months to over a year. If you wait until framing to order a 400-amp meter base or a multifamily meter pack, you can stall the whole project. The fix is simple: bring your electrician in during design so the long-lead gear is ordered months before ground breaks. Connecting permanent power through PGE also takes planning, so start that early too (PGE offers a residential line estimator to scope the cost).
Choosing a contractor for a new build
The electrical package is one of the largest line items in a build and carries real life-safety weight, so the cheapest hourly rate is the wrong filter. Look for:
- Both licenses: an active CCB registration and a BCD electrical contractor license with a licensed supervising electrician who signs the permits and owns the code compliance.
- A real load calculation (NEC Article 220) before anyone signs off on heavy loads like EV chargers or electric water heaters.
- An itemized proposal that specifies device counts, lighting allowances, and panel brand, not a vague lump sum that turns into change orders.
And the biggest red flag: any contractor who suggests skipping permits or having you pull an owner-builder permit to save money. Unpermitted electrical work can void insurance, create disclosure problems at sale, and trigger steep investigation fees. We pull the permit, coordinate PGE, and carry the work through every inspection. We do this across the Portland metro, the Columbia Gorge, and Southwest Washington, and you can see our coverage on our Portland electrician page.
Frequently asked questions
How much does electrical cost for a new house in Portland?
About $4 to $9 per square foot for a standard build, and up to roughly $12 per square foot for high-end or smart homes. That covers labor, rough-in materials, standard devices, the panel, the service entrance, and the permit, but not decorative light fixtures, which are usually owner-supplied. A 1,800-square-foot spec home typically lands around $7,000 to $12,000.
Why does a small ADU cost almost as much per square foot as a custom home?
Because a 700-square-foot ADU still needs the full infrastructure of a house: its own subpanel or meter, a kitchen circuit package, bathroom GFCIs, and HVAC feeds, plus a trench to run the feeder from the main building. You lose the economies of scale that a larger home gets, so the per-square-foot cost climbs.
What size electrical service does a new home need?
200-amp service is the modern minimum. Heat pumps, induction ranges, electric water heaters, and EV charging have made 100-amp service inadequate for a new build. Larger or fully electric homes often go to a 400-amp service.
Does a new home have to be EV and solar ready in Oregon?
Yes. New homes must be wired to support at least one Level 2 EV charger (a dedicated 240-volt circuit to the garage or driveway), and must include solar-ready provisions like a conduit pathway to the roof and reserved panel space. Larger multifamily buildings must make a share of parking spaces EV-capable.
How early should I bring in the electrician for a new build?
During the design phase, not at framing. In 2026, engineered gear like large meter bases, switchgear, and multifamily meter packs can have lead times of many months to over a year. Ordering early and starting the PGE connection process up front is the main way to avoid schedule delays.
Who can legally do new construction electrical in Oregon?
A contractor with both an active CCB registration and a Building Codes Division electrical contractor license, with a licensed supervising electrician who signs the permits. The work must be permitted and pass the full inspection sequence to clear occupancy.
