New Construction Electrical Services That Pass First Time

New construction electrical isn't a job you fix after the drywall goes up. The rough-in stage sets every circuit path, load calculation, and code requirement for the life of the building, which means mistakes stay hidden until they fail inspection or trip a breaker at 2 a.m. All Electric holds CO License #ME.0600978, carries full insurance, and has completed new house wiring and light commercial builds across the Front Range for nine years. Every install is permitted, inspected, and backed by a one-year labor warranty. Call (720) 951-4619 before your slab pours. That's when coordination matters most.

Our electrical construction services cover the full project arc: service entrance planning, load calculations, rough-in wiring, panel sizing, circuit layout for kitchens, baths, HVAC, EV pre-wires, and final trim-out. What drives cost on a new construction job is scope and service size. A 1,200-square-foot addition with a 100A sub-panel sits at a very different price point than a full 3,500-square-foot home wired for 200A with multiple dedicated circuits and smart-home integration. Every job is different, contact All Electric for an accurate estimate.

What We Cover on a New Build

From service entrance to final trim, one licensed contractor, start to finish.

  1. 01

    Service Entrance and Meter Loop

    We coordinate with the utility on service sizing and install the meter base, weatherhead, and conduit runs required before the utility will connect. Getting this right on the first inspection saves weeks on your occupancy timeline.

  2. 02

    Load Calculations and Panel Sizing

    We size the main panel to carry your actual load, not a rough guess. That means accounting for HVAC tonnage, appliance circuits, EV charging, and any future expansion the owner plans. An undersized panel in new construction is a code violation waiting to happen.

  3. 03

    Rough-In Wiring

    Box placement, circuit runs, conduit where required, and wire gauge selection all happen here. We pull the permit, schedule the rough-in inspection, and don't move to the next phase until we have a pass. No shortcuts at the stage you can't see once the walls close.

  4. 04

    Dedicated Circuits and Appliance Wiring

    Kitchens, laundry rooms, and mechanical spaces each carry their own dedicated circuit requirements. We wire these separately from general lighting circuits so a tripped breaker in one area doesn't pull down the rest of the house.

  5. 05

    Final Trim-Out and Device Installation

    Devices go in after finish work is complete. We install outlets, switches, cover plates, panels, breakers, and fixtures to the spec on file with the permit. Final inspection sign-off is our benchmark, not yours.

  6. 06

    Sub-Panels and Detached Structures

    Garages, ADUs, and outbuildings typically need their own sub-panel wiring fed from the main service. We size and install those feeders during rough-in so the conduit path is clean and the inspector doesn't flag incomplete work.

Code Compliance

Rough-In Inspections Are Not Optional

Some electrical contractors in this market skip the rough-in inspection or call it in before the work is complete. We don't operate that way. The rough-in inspection is the only point in a new build where an inspector can verify wire gauge, box fill, circuit separation, and grounding before the walls close. Passing it on the first visit keeps your framing crew moving and keeps your GC from eating delay costs. All Electric pulls every required permit for new construction work. That's not an upsell. It's the law in Colorado, and it protects the owner at resale. If a previous contractor did rough-in work without a permit, you're looking at electrical code violations that have to be corrected before a CO issues. We've walked enough buyers through that situation to know it's never worth the shortcut. Our license number is ME.0600978. Any electrician on a new construction site in Colorado should be able to show you theirs.

How We Work

Three Phases, One Point of Contact

  1. 01

    Pre-Construction Planning

    We review plans, calculate loads, and file for permits before the first nail goes in. Coordinating with your GC and utility at this stage prevents the scheduling conflicts that cost money later.

  2. 02

    Rough-In and Inspection

    Wire runs, conduit, box placement, and grounding are installed and inspected before walls close. We schedule the inspection and stay on site until we have a signed pass.

  3. 03

    Trim-Out and Final Sign-Off

    Devices, panels, fixtures, and covers are installed after finish work. We schedule and pass the final electrical inspection, then hand off documentation to the GC for the CO package.

Light Commercial Construction Wiring

Most residential electricians stop at single-family homes. All Electric handles light commercial new construction, tenant improvements, small office builds, and mixed-use projects where the electrical design has to account for higher loads, three-phase capacity questions, and commercial inspection requirements. We're not a one-trick residential shop. If you're a general contractor sourcing an electrical sub for a commercial project in the Front Range, our license covers the work and our track record, 4.9 stars across 468 Google reviews, reflects the consistency you need on a job site with multiple trades moving at once. Financing options are available on qualifying projects; ask when you call. We also wire heating and AC circuits for new mechanical installations, which matters on commercial builds where HVAC loads are often the largest single circuit draw in the system.

Safety Systems Every New Build Needs

01

Smoke and CO Detection

Colorado code requires interconnected smoke and carbon monoxide detectors in new construction. We wire them into the circuit so a single alarm triggers all devices, not just the one in the room where the problem starts.

02

GFCI Protection

Kitchens, bathrooms, garages, and outdoor locations all require GFCI outlets in new construction. We install these per NEC requirements. Not just where an inspector will look, but everywhere code applies.

03

Arc-Fault Circuit Interrupters

AFCI breakers are required in bedrooms and most living spaces in new Colorado construction. They detect the specific waveform pattern of an arcing fault before a fire starts. We spec and install these at the panel, not as an afterthought during trim-out.

04

EV Charger Pre-Wire

Running a dedicated 240V circuit to the garage during rough-in costs a fraction of what it costs to add later. If the owner plans to charge an EV in the next five years, we run the conduit now and cap it. The charger goes in when they're ready.

New Construction Electrical: Common Questions

What size electrical panel does a new construction home need?
Most new single-family homes are wired for a 200A main panel, which handles standard loads plus EV charging and electric appliances without headroom problems. Larger homes over 3,500 square feet, or homes with multiple HVAC systems and hot tubs, sometimes warrant a 400A service or a main panel with a sub-panel in a detached garage. We calculate the actual load before recommending a size, guessing costs more to correct later.
When does the electrician need to start on a new construction project?
Rough-in begins after the framing inspection passes and before insulation goes in. The earlier we're coordinating with your GC, the better, service entrance location, panel placement, and conduit routing decisions made at the framing stage affect everything downstream. Calling us after drywall is hung means cutting open walls that just got closed.
How many inspections does new construction electrical require in Colorado?
At minimum: a rough-in inspection before walls close, and a final inspection before occupancy. Some jurisdictions and project types add a service entrance or meter base inspection depending on utility coordination. We manage the inspection schedule and stay on site for each one. A failed inspection on our work is our problem to fix, not yours.
Do I need a separate electrical permit for a detached garage on a new build?
Yes. Detached garages and ADUs typically require their own electrical permit, even if they're fed from the main service on the primary structure. The feeder from the main panel to the sub-panel in the detached structure is permitted work. We pull both permits at the same time when a build includes a detached structure to keep the inspection schedule aligned.
What's the difference between a rough-in and a trim-out on a new construction electrical project?
Rough-in is everything that goes inside the walls: conduit, wire runs, box placement, and grounding conductors. Trim-out is the finish phase after drywall and paint: devices, outlets, switches, cover plates, breakers, and light fixtures. The rough-in inspection happens between these two phases. Skipping or rushing the inspection to get drywall up faster is the most common mistake builders make on new electrical work.
Can a licensed electrician also handle the HVAC wiring on a new build?
We wire the circuits for HVAC equipment, the dedicated breakers, disconnect boxes, and conduit runs to the equipment location. The refrigerant and mechanical connections are handled by your HVAC contractor. Coordinating those scopes early in the project means the heating and AC circuits are sized correctly before the mechanical equipment is even ordered.
