Average Installation Cost by Project Type
Every commercial installation is different, and the type of space you’re wiring has a big impact on cost. An office might call for lighting layouts and data cabling, while an industrial space could need heavy-duty wiring and higher voltage systems. Here are typical cost ranges based on the most common types of commercial projects:
| Project Type | Estimated Cost per Sq Ft | Typical Project Cost Range | Project Description |
| Office Buildout | $6.00 – $12.00 | $15,000 – $75,000 | Includes lighting, outlets, panels, and basic data wiring in an office environment |
| Warehouse Fit-Out | $4.00 – $9.00 | $10,000 – $60,000 | Focuses on utility wiring, high bay lighting, and power distribution in open warehouse spaces |
| Retail Store | $6.50 – $13.00 | $20,000 – $85,000 | Covers sales floor lighting, display circuits, checkout power, and signage wiring |
| Restaurant Kitchen | $9.00 – $15.00 | $25,000 – $95,000 | Includes high-demand kitchen equipment wiring, GFCI outlets, and exhaust fan circuits |
| Multi-Tenant Facility | $7.00 – $14.00 | $40,000 – $160,000 | Covers common area power, metered service to each unit, and tenant-specific panel setups |
Numbers are based on averages and can vary depending on complexity and local markets.
Cost Differences by U.S. Region
Two commercial projects with the same plans can end up with very different price tags, depending on where they are built. In some cities, you might need multiple permits and inspections before work can even begin. Projects in rural areas might require longer material lead times or have limited choices when it comes to suppliers. All of these factors can impact the cost of a project. Even things like seasonal weather and utility coordination can affect your schedule and budget.
Here are typical labor and installation costs based on regional averages:
| Region | Average Labor Cost per Hour | Installation Cost Range per Sq Ft |
| Northeast | $95 – $125 | $7.00 – $14.00 |
| Midwest | $80 – $110 | $5.50 – $11.00 |
| South | $75 – $105 | $5.00 – $10.00 |
| West Coast | $100 – $135 | $8.00 – $15.00 |
What Impacts Commercial Electrical Installation Costs?
Electrical costs can vary widely, even for buildings with the same square footage, because no two commercial projects are exactly alike. One project might need basic lighting and outlets, while the other calls for specialized systems, heavier wiring, or added safety features. If you’re budgeting for a project, it helps to know what drives those numbers up or down. Below are the factors that tend to have the biggest impact.
Size and Scope of the Project
Larger square footage means more wiring, more devices, and more labor, but complexity also plays a role. For example, a 5,000 sq ft office with standard lighting will cost less than a 3,000 sq ft restaurant kitchen that requires dedicated circuits and 3-phase power.
Building Type and Usage
Each type of commercial space comes with its own electrical demands. These unique needs directly impact both material and labor costs. For example:
- Restaurants need GFCI outlets, heavy-duty wiring for appliances, and dedicated circuits.
- Retail stores require track lighting, signage power, and clean ceiling work.
- Offices may need structured cabling for the internet and integrated AV systems.
Local Labor Rates and Permitting
Wages for licensed electricians vary significantly by region. Areas like the West Coast and Northeast typically carry higher hourly rates, sometimes $100+ per hour, while Southern or Midwestern areas may fall closer to $75. Local codes and permitting fees can also increase costs, especially if multiple inspections or advanced load calculations are required.
Service Panel and Power Requirements
Older buildings often need panel upgrades to handle today’s energy loads. If your project requires 3-phase power, a new transformer, or multiple subpanels, your price will increase accordingly.
Accessibility and Jobsite Conditions
Challenging conditions like slab foundations, drop ceilings, or working in active business hours can add time and labor to the job. Likewise, buildings without clear access routes for conduit runs, or those requiring after-hours work, will add to project costs.
Timeline and Scheduling Constraints
Fast-track projects often cost more. If your installation must be completed on a tight timeline, expect to pay overtime rates or premium pricing for accelerated scheduling. Projects scheduled around open business hours may also require more coordination and labor shifts.
Material and Equipment Choices
Material and equipment costs add up quickly for specialized projects. Assume your material costs will be higher if your installation requires equipment such as:
- Fire-rated cabling
- Backup generators
- Surge protection systems
- Smart lighting or automation
Code Requirements and Compliance Upgrades
Every city has its own interpretation of the National Electrical Code (NEC). If your inspector requires conduit-only systems or mandates fire caulking and emergency signage, those extras add up. In some regions, electrical work must be completed by union labor or adhere to specific energy efficiency standards, which can also impact your budget.

Frequently Asked Questions
What’s included in this calculator estimate?
Our calculator includes estimated labor, wiring, panels, outlets, breakers, and conduit costs. It does not include high-end lighting fixtures or specialty systems, such as fire alarms.
Do I need a permit for commercial electrical work?
Yes, most cities and counties require a permit and inspection for new installations or major upgrades.
How long does installation take?
Most commercial installations take 2–6 weeks, depending on the system’s complexity and square footage.
Can I use residential electricians for commercial jobs?
It’s not recommended. Commercial electricians have specialized training and licensing for higher voltage, building codes, and commercial-specific systems.
