Service and utility coordination
Confirm the serving utility, service location, overhead or underground route, meter requirements, utility responsibilities, documents, lead times, and energization sequence.
What to know before you get started.
We handle the entire electrical scope of your new home wiring, from service size planning to rough-in, trim, and final inspection. This covers both owner-managed new builds and commercial developments.
Start with service and load planning
The building use, equipment, utility point, future loads, and site plan shape the service, meter, panel, feeder, and distribution decisions.
Calculated and future loads
List heating, cooling, water heating, cooking, vehicle charging, pumps, shop equipment, commercial equipment, and realistic future additions before sizing distribution.
Panels, feeders, and circuit layout
Coordinate panel locations, working access, feeder routes, circuit groups, equipment connections, spare capacity, labeling, and building-to-building distribution.
Lay out lighting, devices, and equipment
Room use and equipment plans should drive fixture, outlet, switch, control, circuit, and connection locations before rough-in begins.
Lighting and controls
Coordinate fixture layouts, switching, dimming, sensors, exterior lighting, equipment ratings, ceiling conditions, and owner-furnished products with the reflected plan.
Outlets and switches
Review furniture, counters, cabinets, doors, equipment, accessibility, exterior use, controls, device locations, protection, and any dedicated circuit needs.
Appliances and building equipment
Use final ratings and installation information for appliances, HVAC, pumps, chargers, tools, commercial equipment, and controls before circuits are released.
Low-voltage boundaries
Identify which provider handles data, communications, security, audio, controls, pathways, equipment, termination, testing, and any coordination with electrical power.
Match electrical work to construction milestones
The electrical schedule depends on site access, service decisions, framing, equipment selections, other trades, inspections, insulation, finishes, and utility availability.
Underground and service work
Coordinate trenches, sleeves, utility separation, building entries, pads, backfill approval, inspections, and site restoration before routes are covered.
Rough-in and inspection
Finalize layouts, equipment, circuits, boxes, supports, pathways, and changes before rough-in inspection, insulation, drywall, cabinets, and finishes.
Trim, testing, and final inspection
Sequence devices, fixtures, equipment connections, labeling, testing, correction items, utility energization, owner-furnished products, and final inspection.
Control decisions and scope changes
A new building changes as selections become final. Written decisions keep electrical revisions, cost, schedule, and responsibility boundaries visible.
Plans and equipment schedules
Keep current drawings, room uses, fixture selections, equipment ratings, control information, and utility documents available to the electrical team.
Alternates and future phases
Separate required work, preferred options, future capacity, owner-furnished equipment, and deferred features so each decision remains understandable.
Additions and remodels
Use the remodel page when new work connects to an occupied or existing building and existing circuits, finishes, access, or concealed conditions drive the scope.
Questions about new-construction electrical planning
When should an electrician join a new-construction project?
Before service, equipment, lighting, device, and utility decisions are fixed. Early coordination reduces conflicts before underground work, rough-in, insulation, and finishes.
What electrical information is needed before rough-in?
Current plans, room uses, equipment ratings, fixture and control selections, panel locations, utility information, owner-furnished items, and approved changes should be available.
How is electrical capacity planned for a new building?
Calculated loads, building use, equipment ratings, simultaneous demand, utility requirements, distribution, and realistic future additions guide service and panel decisions.
Does this page cover additions and renovations?
Use the remodel page when existing circuits, occupied areas, finishes, access, or concealed conditions drive the work. This page owns planning for a new building.
Who wires a new house, the builder's electrician or one I hire myself?
If you are working with a general contractor on a turnkey home build, they typically have an established relationship with a subcontractor who handles all electrical work. However, if you are managing the build yourself as an owner-builder, or if your contract allows you to select your own tradespeople, you can hire an independent electrician directly. We recommend discussing this option with your builder early in the planning process to clarify roles, scheduling, and contract terms.
How much does wiring a new house cost and how is it calculated?
The cost to wire a new home depends on several design and structural choices rather than a flat rate. Key cost drivers include the square footage, the required service size (such as 200-amp or 400-amp service), the complexity of your light fixtures, and whether you are preparing for future additions like an EV charger or hot tub. To get an accurate, firm price for your project, you should provide a set of architectural plans or electrical layouts to obtain a detailed, line-item quote based on your specific scope.
