How Much Does It Cost to Wire a New House?

For a new-construction home, the useful budget question is not one universal price. It is what electrical scope is included in the quote: rough-in wiring, finish devices and fixtures, panel and service work, permits and inspections, utility coordination, low-voltage pathways, trenching, and allowances for owner selections.

The existing article listed a broad wiring range from $8,000 for a basic starter-home setup to $22,500 for a larger, higher-spec build. Those figures are retained here as indicative legacy planning numbers only. They are not verified current quotes, and they should be checked against local drawings, electrician pricing, adopted code requirements, utility rules, fixture schedules, and material costs before they are used in a proposal.

New Construction Is Different From Rewiring

This guide is about wiring a new house while framing is open. A retrofit rewire has different labor because electricians may need to fish cable, open and patch walls, work around occupied spaces, and protect finished surfaces. Do not use a new-construction square-foot allowance as a retrofit price without a separate site walk.

Use Square Footage Carefully

Square-foot allowances are useful for early budgeting, but they can hide scope gaps. The earlier copy referenced about $4 per sq. ft. for basic wiring and $9 per sq. ft. for smart-home-ready packages in San Antonio. Keep those as rough example allowances, not current market proof. Clarify whether the area is conditioned floor area, total under-roof area, garage area, porch area, attic or basement space, and whether the allowance includes rough-in only or both rough-in and finish.

Separate The Main Cost Drivers

  • Rough-in labor and materials: cable or conduit, boxes, homeruns, temporary power coordination, and crew time before insulation and drywall.
  • Finish devices and fixtures: switches, receptacles, plates, trims, light fixtures, fans, appliance connections, and fixture allowances.
  • Panel and service scope: panel size, service entrance work, meter equipment, grounding and bonding, disconnects, surge protection, and utility requirements depend on the designed load and local rules.
  • Dedicated loads: HVAC, ranges, dryers, water heaters, pumps, workshops, EV chargers, solar-ready pathways, batteries, generators, and other specialty loads can change the circuit and service design.
  • Low-voltage and smart-home scope: data, security, cameras, speakers, access control, conduit pathways, panels, and device trim should be priced separately from line-voltage wiring.
  • Permits, inspections, and utility work: permit fees, inspection trips, plan review, trenching, boring, utility coordination, temporary service, and reinspection fees can sit outside a basic wiring allowance.

Panel And Service Numbers Need Qualification

The previous copy mentioned 200-amp and 400-amp examples and listed $2,500 and $5,000 service-related figures. Treat those as retained historical estimating notes, not recommendations for a house. Service size, panel configuration, grounding, required protection, conductor types, breaker types, and load calculations must be determined by a qualified electrician or electrical engineer using the locally adopted code and utility requirements.

Permit And Inspection Allowances

The earlier article referenced Texas permit fees from $250 to $900. Keep that as a placeholder allowance only. Actual fees vary by city, county, utility, project valuation, inspection count, plan-review process, and whether reinspection or temporary-power charges apply.

Indicative Scenarios To Check Against The Drawings

Scenario A: 2,200 sq. ft. starter home
Retained legacy subtotal: $8,000. Confirm whether this includes rough-in and finish, fixtures, permits, service equipment, utility coordination, and low-voltage scope.

Scenario B: 3,800 sq. ft. smart-ready family home
Retained legacy subtotal: $18,000. Confirm what smart-home pathways, data/security devices, panel capacity, and finish allowances are included.

Scenario C: 5,100 sq. ft. higher-spec build
Retained legacy subtotal: $22,500. Confirm whether service upgrades, specialty loads, lighting controls, EV or solar provisions, trenching, and fixture selections are included.

Quote Checklist For New-House Wiring

Electrical scope affects safety, inspection approval, schedule, and final price. This article is for cost planning and proposal scoping only. It is not DIY electrical instruction. Do not work on live circuits, and do not use online cost examples as design instructions for amps, wire gauges, breaker sizes, spacing, grounding, bonding, or required protection.

Before a wiring number goes into a bid, ask the licensed electrical contractor, electrical engineer where applicable, authority having jurisdiction, and utility what the project actually requires. OSHA describes electrical work as a serious workplace hazard involving risks such as electric shock, electrocution, fires, and explosions; OSHA's construction electrical resources also point to construction standards, hazard recognition, grounding, protective devices, and safe work practices.

What To Ask Before Accepting A Wiring Quote

  • Is the quote for rough-in only, finish only, or a complete rough-in plus finish package?
  • Does it include panel, meter, service entrance, grounding, bonding, disconnects, surge protection, and utility coordination?
  • Are light fixtures, fans, trims, devices, plates, smart switches, and specialty controls included or listed as allowances?
  • Are dedicated appliance loads, HVAC equipment, pumps, exterior circuits, garage/workshop loads, EV charging, solar-ready pathways, battery/generator provisions, and low-voltage systems shown separately?
  • Are trenching, boring, temporary power, utility connection fees, plan review, permit fees, inspection trips, and reinspection fees included?
  • Does the quote list exclusions, alternates, escalation terms for copper or gear, change-order rates, and fixture allowance assumptions?
  • Has the electrician reviewed the electrical drawings, architectural drawings, equipment schedule, lighting schedule, and any owner selections?

Using CountBricks For Proposal Scope

CountBricks can help contractors organize electrical estimate line items, allowances, notes, exclusions, taxes, markups, quotes, and proposal documents in one workflow. It does not replace the licensed electrical contractor, engineer, local inspector, or utility. Use it to keep scope assumptions visible before sending a customer-facing proposal. See the CountBricks estimates workflow for proposal preparation.

Source And Case-Claim Status

The earlier article included a named Texas Builders Group case study claiming CountBricks reduced wiring costs by $4,000, from $15,000 to $11,000. No supporting customer record, permission, project scope, quote, invoice, or source citation was recovered in this audit, so the case claim should be removed rather than presented as proof.

Bottom Line

Use the retained dollar figures as early planning placeholders only. A real new-house wiring budget should separate rough-in, finish, service, permits, utility, low-voltage, specialty loads, fixture allowances, and exclusions, then be confirmed by qualified electrical professionals before the number becomes a contract proposal.
