Commercial tenant improvement electrical
A tenant improvement turns a shell into a working space. The electrical scope follows the floor plan and the lease.

The short answer
Commercial tenant improvement electrical work is done by a licensed electrical contractor to permitted drawings: new circuits for workstations and equipment, lighting and lighting controls under the energy code, data and low-voltage coordination, and panel work, inspected at rough-in and final. The lease decides who pays and who owns the work.
What the scope includes
Panel and feeder review, branch circuits for outlets and equipment, lighting with occupancy and daylight controls as energy codes require, exit and emergency lighting coordination, and low-voltage pathways.
Drawings and permits
Most jurisdictions require stamped or permit drawings for commercial work. The landlord may have building standards and approved contractors.
Safety on site
OSHA 1910.303 sets general electrical requirements for workplaces, including working space around equipment. Contractors follow it and NFPA 70.
Time and what changes the price
Schedule ties to the general contractor, permits and inspections.
Price drivers: square footage, outlet and fixture density, controls, panel work, after-hours work. No price ranges are published here until we hold enough sourced, dated quotes; see cost guides.
Choosing a contractor
Ask for commercial license, bonding and insurance, and similar project references. Check the license on your state board before anyone starts: how to check an electrician license.
Lease and landlord questions
Before design starts, ask the landlord what the existing service and panel can supply to your space, whether there is a building-standard lighting fixture, who maintains the electrical room, and whether after-hours work is required for occupied buildings.
Check whether the lease requires you to remove your electrical work at move-out. Removal and make-good work can be a surprise cost at the end of the term.
Equipment-heavy tenants such as labs, salons, gyms and medical offices should share their equipment list early. Heavy loads may need a new feeder or a larger panel that only the landlord can approve.

Primary-source research and fact checking
We read the model code, the federal safety notice, the municipal fee sheet or the utility tariff ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. HyreElectrical does not perform, supervise or warrant electrical work. Authorship is organizational: this desk, not a named persona.

How this desk works
- Primary sources only. Code statements come from NFPA 70 as the model code. Safety statements come from CPSC. Permit fees come from the city or county fee sheet. Utility charges come from the filed tariff. We do not cite a blog that cites a source; we open the source.
- Our contractor store is five states, and 74% of it is Florida. Any figure built on that store is titled to those states and names the concentration in the first screen. It is not a national sample of electricians.
- Load calculations on this site are a published simplification in the shape of NEC 220.82 — first 10 kVA at 100%, remainder at 40%, HVAC at 100%, EVSE at 125%. They are labeled as not a stamped calculation. A licensed electrician using the adopted edition does that work.
- No national price for a panel upgrade is shipped. Labor rates, the adopted code edition, whether the utility is involved, and the state of the existing wiring move the invoice too far for a roundup to help. The cost pages publish named permit fees and the variables that move the price instead.
- We do not perform electrical work, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
Sources & retrieval dates
HyreElectrical is a publisher. It does not perform, supervise, inspect or warrant electrical work, holds no electrical license, and matching is still being built, so an inquiry is not a service call.
This page is general information, not a diagnosis or a quote. Code rules vary by the NEC edition your state or city adopted and its local amendments.
