This in-depth guide breaks down typical price ranges for the average electrical cost per square foot for commercial buildings. While average costs can range from around $4 to $15 per square foot, we will discuss which factors impact these numbers. Whether you’re pricing out a new office space, logistics warehouse, or retail center, knowing what to expect can save you time and prevent budget surprises.
Quick Cost Reference: National Averages by Building Type
Here’s a quick look at typical electrical costs per square foot for common types of commercial buildings. These ranges reflect average national pricing and are meant to give you a starting point based on the type of space you’re building or renovating. Keep in mind, project complexity and your exact location can impact these estimates.
| Building Type | Cost Range per Sq Ft | Includes |
| Office | $6 – $12 | Standard lighting layouts, wall outlets, switchgear, panel tie-ins, and data-ready conduit routing |
| Warehouse | $4 – $9 | Basic lighting, power distribution, limited receptacles, and minimal HVAC circuiting |
| Retail | $6.50 – $13 | Display and shelf lighting, checkout power, signage circuits, and back-room wiring |
| Restaurant Kitchen | $9 – $15 | GFCI outlets, 3-phase equipment wiring, appliance circuits, and service panel upgrades |
| Light Industrial | $7 – $14 | Power drops for machinery, panelboard coordination, floor box feeds, and task lighting |
Regional Differences in Cost per Square Foot
Creating estimates of the electrical costs per square foot in commercial buildings can depend significantly on where you are located. In cities with higher wages and stricter permitting, quotes will be higher. While some rural areas are cheaper, others can be more expensive due to fewer supply options or longer lead times. The numbers below offer a general sense of regional pricing.
| Region | Avg. Cost per Sq Ft | Explanation |
| Northeast | $7 – $14 | Costs trend higher due to strict code requirements, multiple inspections, and above-average labor rates in urban markets. Projects here often involve longer permitting timelines and more planning on the front end. |
| Midwest | $5.50 – $11 | This region tends to see steady pricing thanks to moderate labor costs and accessible permitting processes. Materials are generally easy to source, which keeps project timelines predictable. |
| South | $5 – $10 | Labor costs run slightly lower, and project timelines are often more flexible. In many areas, permitting is faster and less restrictive, which can reduce overall installation costs. |
| West Coast | $8 – $15 | Higher costs here are driven by wage rates, environmental code requirements, and extended planning cycles in many cities. Utility coordination and fire code compliance can also push budgets higher. |
Use Cases: Cost Examples by Project Type
Cost per square foot becomes more meaningful when applied to real-world projects. Below are several examples of specific commercial electrical projects across different industries and regions.
| Example Project | Region | Sq Ft | Cost per Sq Ft | Total Cost | Project Details |
| Professional Office | Midwest | 3,500 | $6 – $9 | $21,000 – $31,500 | Basic lighting, outlets, and panel upgrade in a building with easy access via a drop ceiling |
| Restaurant Kitchen | West Coast | 2,000 | $10 – $15 | $20,000 – $30,000 | Heavy-duty wiring, GFCI outlets, dedicated lines for appliances, and 3-phase power |
| Retail Clothing Store | South | 4,200 | $6.50 – $11 | $27,300 – $46,200 | Accent lighting, signage power, and multiple checkout stations |
| Light Industrial Facility | Northeast | 6,000 | $8 – $14 | $48,000 – $84,000 | Floor-mounted equipment, trenching for conduits, and multiple subpanels |
| Medical Office Suite | Midwest | 5,000 | $7 – $12 | $35,000 – $60,000 | Exam room receptacles, data cabling, emergency circuits, and code-specific lighting |
| Brewery & Tasting Room | South | 3,800 | $8 – $13 | $30,400 – $49,400 | Brewing equipment, outdoor lighting, and split service between brewing and front-of-house areas |
| Small Warehouse | West Coast | 7,500 | $5 – $8 | $37,500 – $60,000 | High-bay lighting, single service panel, and simple load distribution |
| Veterinary Clinic | Northeast | 2,800 | $7 – $13 | $19,600 – $36,400 | Lab-grade receptacles, backup power planning, and enhanced lighting for treatment rooms |
What’s Included in These Costs?
The cost per square foot listed in this guide reflects standard electrical installation for commercial buildings. These estimates include both labor and materials, so you’re looking at what it typically costs to get power running through a functional, code-compliant system.
Included:
- Conduit, wiring, and circuiting throughout the space
- Standard outlets, switches, and breakers
- Electrical panels and subpanels (if needed)
- Labor for rough-in, trim-out, and final connections
Not Included:
- High-end lighting fixtures and custom lighting design
- Fire alarm systems, data cabling, and low-voltage systems
- Backup generators or battery storage
- Engineering drawings or permit fees
We made these assumptions based on the most common types of projects. If your space includes specialty systems or detailed coordination with HVAC, AV, or automation, those would typically fall outside the standard cost range.
What Affects Cost per Square Foot?
Electrical pricing isn’t just about square footage. The real cost comes down to what the system needs to do, how the space is built, and how quickly it needs to be finished. Below are some of the most common factors that influence what you’ll pay per square foot.
| Size vs. Complexity |
| A large open space with basic wiring might be more affordable per foot than a small clinic with multiple rooms, data wiring, and emergency circuits. The more moving parts involved, the more labor and materials are required. |
| Power Requirements |
| If your building needs 3-phase power, dedicated equipment lines, or high-load panels, that will push the price higher. These setups are more common in restaurants, breweries, and industrial settings. |
| Access & Layout |
| Drop ceilings make installations easier and faster. Slab-on-grade floors or multi-story buildings often require more labor-intensive work, like trenching or vertical conduit runs. |
| Permitting & Code Requirements |
| Local codes can dictate conduit use, emergency system specs, and even fixture types. Some cities require multiple inspection stages, which adds both time and cost. |
| Timeline & Scheduling |
| If you’re on a tight schedule or need the installation completed in phases to accommodate other trades, labor costs can increase. Overtime work and scheduling with short notice often come at a premium. |

Frequently Asked Questions
How do I know if the per-square-foot estimate applies to my building?
The estimates in this guide apply to most standard commercial spaces, such as offices, retail, restaurants, and light industrial buildings. If your space has unique requirements, such as cleanrooms, specialty labs, or heavy equipment, we recommend getting a custom quote.
Does the estimate include lighting and fixtures?
No. The cost ranges here cover wiring, panels, conduit, and labor, but don’t include decorative or specialty lighting. If you already have fixture specs, we can include those in a detailed quote.
Can you work with existing electrical systems, or does everything need to be new?
We regularly upgrade and expand existing systems. If your panel has capacity and the wiring meets code, we may be able to build on what’s there and reduce your costs.
How soon can you start once I approve the quote?
Timelines vary by project size and permitting, but for many commercial jobs, we can start within 1–3 weeks of approval. We’ll give you a clear schedule upfront so you know what to expect.
Do you pull permits and handle inspections?
Yes. We take care of all required permits and coordinate with local inspectors so everything is code-compliant and ready for sign-off.
What do I need to provide to get an accurate quote?
Ideally, a set of plans or a rough layout with square footage, intended use, and any known power needs (HVAC, kitchen equipment, etc.). If you don’t have plans, we can schedule a site visit.
