Electrical for new construction — bidding GCs, payment cycles, and avoiding scope creep
Published
New construction electrical work — residential subdivisions, custom homes, multifamily, and light commercial ground-up — is the volume revenue line that built most large electrical shops. It is also the line that breaks the most small shops. 2026 residential new construction pricing runs $4.50–$9.50 per square foot for tract production, $6.50–$14.50 per square foot for custom, and $7.50–$18.50 per square foot for high-end custom with low-voltage and smart home integration (verified April 2026 via HomeAdvisor 2026 contractor pricing, NECA 2026 new construction labor rates, and operator reports from TX, FL, CO, and NC). The money is real; so are the failure modes. Below: bidding, payment cycles, retention, change orders, and how to stay solvent while waiting 75 days for draws.
The pricing model
Residential new construction is priced two ways:
Per square foot plumb-through. Rough-in, trim-out, service entrance, temp power. Covers base package — standard outlets, switches, fixtures allowance, 200A panel. Does not cover upgrades.
Line-item quote. Detailed takeoff from architectural and electrical plans. Each outlet, fixture, circuit, panel, and device is priced. Used for custom and high-end jobs where the base package does not apply.
Tract production builders want per-square-foot; custom builders want line-item. Both are legitimate. Knowing which you are dealing with is the first qualifier.
2026 pricing bands
| Construction type | Per sq ft (electrical only) | Notes |
|---|---|---|
| Tract production, base package | $4.50–$6.25 | Standard outlets/switches, 1 panel, 200A, no smart devices |
| Tract production, upgrade package | $6.25–$8.50 | USB receptacles, smart switches at key locations, Cat6 to media room |
| Custom home, mid-market | $6.50–$10.50 | 200–400A service, higher fixture count, some LV |
| Custom home, high-end | $10.50–$14.50 | 400A, smart home rough-in, more dedicated circuits |
| Luxury custom with full integration | $14.50–$22.50 | HomeWorks/Control4 rough-in, structured cabling, security rough-in |
| Multifamily (per unit, 2-bed) | $3,800–$7,500 | Based on unit electrical only; not common areas |
| Light commercial TI | $12.00–$28.00 | Hugely variable by scope; TI = tenant improvement |
Ranges verified April 2026 via regional NECA bid averages and general contractor payout reports. For panel-specific detail see our residential panel upgrade business guide.
The bidding process — what GCs actually want
The bid package request from a GC typically includes:
- Architectural plans (A-series sheets)
- Electrical plans (E-series sheets, if separate)
- Specifications (Division 26)
- Schedule milestones
- Insurance and bond requirements
- Payment terms
- Retention percentage and release timing
Experienced GCs will send all of this upfront. Less-experienced GCs will send partial information and expect you to ask for the rest. Ask for the rest — unpriced unknowns become change-order arguments later.
The takeoff
Accurate takeoffs drive bid accuracy. Modern electrical estimating uses digital takeoff software that counts devices from PDF plans:
| Tool | 2026 pricing | Best for |
|---|---|---|
| McCormick Estimating | $149–$349/mo | Production residential, mid-commercial |
| Accubid (Trimble) | $250–$650/mo per seat | Large commercial, engineering-heavy work |
| ConEst IntelliBid | $185–$495/mo | Mid-market commercial |
| Bluebeam Revu + Excel | $299/year + labor | Solo and small shops |
| PlanHub + Takeoff | $99–$299/mo | Smaller commercial |
| Esticom (by Procore) | Included in Procore tier | Shops already on Procore |
Verified April 2026 via vendor pricing pages and operator reports. Deeper comparison in our commercial electrical bid management software guide.
A realistic takeoff for a 3,200 sq ft custom home runs 4–8 hours for a competent estimator, plus 1–2 hours for pricing and proposal formatting.
Payment cycles — the cash flow reality
New construction payment cycles break small electrical shops more than any other single factor. The 2026 typical timeline on custom residential with a reputable GC:
| Event | Day |
|---|---|
| Rough-in started | Day 1 |
| Rough-in 50% complete | Day 14 |
| First progress billing submitted | Day 14 |
| GC review + submission to owner | Day 21 |
| Owner bank/lender draw processing | Day 35 |
| Payment received | Day 45–60 |
| Retention held until final lien waiver | +30–90 days after substantial completion |
That is the well-run version. Less-reputable GCs push payments 75–120 days, pay short against draws, and use retention as a renegotiation lever.
Retention — the money you do not have
Retention (retainage) is an industry convention where the GC withholds a percentage of each progress payment until the job is substantially complete and final lien waivers are signed. Typical 2026 retention:
- Residential custom — 5–10% of each progress billing
- Multifamily and light commercial — 10% standard
- Public works — 5–10%, state-dependent
- Large commercial — 5–10%, sometimes reduced to 0% after 50% completion
On a $180,000 electrical contract with 10% retention, $18,000 sits with the GC until the job is done. For a three-tech shop, that is 3–6 weeks of payroll.
Some states (California, Texas, Florida, Illinois, New York among others) have prompt-pay statutes limiting how long retention can be held after substantial completion. Know your state.
Scope creep — the margin killer
Scope creep eats more margin on new construction than any other single factor. Typical patterns:
- Owner walks through the framed-in house and wants outlets added. Each unrecorded add = margin loss.
- Designer changes fixture package mid-job. New fixtures have different can sizes, housing types, wiring requirements.
- HVAC subs change equipment. New condenser unit needs a different disconnect location; your original trenched whip is now wrong.
- Permit inspector requires code updates. A plan approved under prior code now needs AFCI or GFCI additions.
- GC "asks a favor." "While you're here, can you also pull a line to the shed?" No. Write a change order.
The discipline: every deviation from the original scope generates a written change order, signed before the work starts. Shops that hand GCs a stack of change orders at job close to "true up" lose those negotiations.
Change order pricing
Change orders carry a premium over original-scope pricing, and GCs expect this. Typical markup:
- Time-and-material change — loaded labor rate + 15–25% markup on materials
- Lump-sum change — 20–35% premium over equivalent in-scope pricing
- Emergency change (rush) — 40–75% premium
A 20% change-order premium is standard. GCs who push back on that are either inexperienced or difficult; either way, you want to know.
Lien rights — the last line of defense
Mechanic's lien rights protect the sub from non-payment. Requirements vary by state but usually involve:
- Preliminary notice sent within 20 days of first furnishing labor or materials
- Notice of intent to lien sent before filing
- Lien filing within a state-specific window (typically 90–180 days from last furnishing)
- Foreclosure action within a state-specific window (typically 1 year from lien filing)
File preliminary notices on every job over $10,000. It is a $50 mailing; it protects a $50,000 account. Services like Levelset, SunRay, and NCS Credit handle notice and filing for small shops.
Insurance and bonding
New construction usually requires:
- General liability — $1M / $2M minimum, higher for commercial
- Workers comp — per state rules
- Commercial auto — $1M typical
- Umbrella — $1M–$5M depending on contract size
- Performance bond — on public work or large commercial; typically 10–15% bond premium rate for newer shops
See our contractor insurance basics and commercial fleet insurance guides for deeper coverage detail.
Software fit for new construction
New construction has different software needs than service work:
- Estimating — McCormick, Accubid, ConEst for takeoff and bid
- Project management — Procore, Buildertrend, CoConstruct for GC coordination
- ServiceTitan — handles the service side; limited PM capability on construction jobs
- Housecall Pro — primarily service, weak on construction PM
- Jobber — project tracking at higher tiers; fits smaller custom work
- Workiz — service-dispatch-oriented
Shops that run both service and new construction typically use one tool for service (ServiceTitan, Housecall Pro) and a separate tool for construction PM (Procore). Full comparison in our electrical contractor software overview.
Common mistakes
- Bidding without the specs. Drawings alone are not the scope.
- Not filing preliminary notices. Unprotected accounts die quietly.
- Accepting single-page subcontracts from GCs. Read the full contract. Pay-when-paid clauses can leave you holding $40,000 that you are never getting.
- Starting work before the contract is signed. "We'll sign next week" means the work is half-done when the contract terms change.
- Undersizing your line of credit. New construction eats cash. A shop doing $1M/year in new construction needs a $150–$250K line to cover the gap between billing and payment.
