Electrical & data for tenant upfits

Electrical and data for tenant upfits — retail and office spaces

When the lease turns over and the floor plan changes, the electrical and data have to change with it. Tessco is the electrical and data contractor on the job — circuits, lighting, equipment feeds and network cabling — working with your GC, landlord or franchise team.

What a tenant upfit is, in plain English

A tenant upfit (also called a tenant improvement) is the work that makes a leased space match the next tenant. Walls move. Sales counters move. Equipment gets added. That means outlets, lighting layouts and dedicated circuits have to move or get installed new — then pass inspection before you open the doors.

It is not the same job as swapping a residential panel. The paperwork, the landlord rules and the schedule around open hours are different. Broader commercial electrical (panels, troubleshooting, GC sub work) lives on the commercial electrical page.

Typical scopes we take

If the job is heavy industrial process power or a multi-story shell, say so — we will tell you straight if it is outside how we crew work.

How Tessco shows up

Our scope is electrical and data: service and panel capacity, branch circuits, lighting, equipment feeds, low-voltage/network cabling, rough-in and finish, permit and inspection for our scope. We are not the general contractor on upfits; we work alongside the GC, landlord or franchise team and fit our rough-in and finish to their schedule. You get one number for the electrical and data — Chad answers.

Common questions

What is a tenant upfit?

A tenant upfit (tenant improvement) is the work to make a leased space match the new tenant’s floor plan and equipment. Walls move, so outlets, lighting and dedicated circuits have to move or get added — then pass inspection before you open.

Do you do the whole upfit?

No. On tenant upfits our scope is the electrical and data: power, lighting, equipment circuits and low-voltage/network cabling. The general contractor, landlord or franchise team handles the rest of the build. We will tell you up front what is in our scope.

What should I send before you quote?

A floor plan if you have one, an equipment list (amps and voltages if known), landlord or franchise requirements, and the address. Photos of the existing panel help.

Can you work around an open business?

Often yes. We write the schedule around what has to stay powered and when the space can be shut down for rough-in or cutovers. Say that up front so the scope matches reality.
