How Commercial Tenant Improvement Buildouts Work, Start to Finish

For property owners and GCs: how the electrical scope of a TI buildout actually flows, and where schedules are won or lost.

How Commercial Tenant Improvement Buildouts Work, Start to Finish

Every tenant improvement lives or dies on schedule, and electrical sits on the critical path of almost every TI. Here is how we run the electrical scope of a buildout so the trades behind us start on time and the certificate of occupancy lands when the lease says it should.

Preconstruction: Where Schedules Are Won

The best TI electrical work happens before anyone touches a wire: load calculations against the existing service, early utility coordination if capacity needs to grow, and a permit package that anticipates plan-check questions instead of answering them in correction cycles. We price from real site walks, not square-footage guesses.

Rough-In and Coordination

Once demo opens the space, electrical rough-in sets the pace. Panel and outlet relocations to fit the new layout, dedicated circuits for commercial kitchens and equipment, and structured low-voltage rough-in for data, all sequenced with the framing and mechanical trades so nobody waits on anybody.

  • Electrical sits on the critical path of nearly every TI
  • Early load calcs prevent mid-project utility surprises
  • LED retrofits often qualify for utility rebates
  • First-pass inspections are a planning outcome, not luck

Lighting, Life Safety, and Finish

Modern TI lighting is LED with occupancy controls, which lowers the tenant's operating costs and usually qualifies for utility rebates. Emergency egress and exit lighting, plus fire alarm rough-in, get inspected hard, so we build them to pass the first walk, not the second.

Inspection and Certificate of Occupancy

The CO waits on the final electrical inspection more often than any other trade. We schedule inspectors early, walk the job with them, and clear corrections same-week. The paperwork is our problem, not the owner's.
