Fit-out electrical checklist

Signing a lease on a new office, shop or clinic? These are the electrical questions to answer before you commit — and before the GC starts the clock.

Before you sign

  • Available capacity: what service feeds the unit, and is there spare capacity for your equipment?
  • Landlord work vs tenant work: who pays for the panel, distribution and lighting?
  • Landlord rules: approved contractors, working hours, shutdown procedures, insurance requirements.

During design

  • Dedicated circuits for kitchen, medical, IT or specialty equipment
  • Lighting layout and controls (occupancy and daylight sensors)
  • Emergency and exit lighting to the Fire Code
  • Signage power and storefront lighting
  • Data pathways and fire alarm coordination

Permits and close-out

Electrical work needs ESA notification and inspection; building permits are separate. At close-out you should receive panel schedules, as-built markups and test records for emergency lighting.

See commercial fit-outs.

Quick questions

Who pays for electrical in a fit-out?

It depends on the lease. Landlord's work and tenant's work are usually spelled out — check before you sign.

How long does fit-out electrical take?

Small units can be a few weeks; larger fit-outs follow the GC's schedule and permit timelines.

Do I need an engineer?

Larger or more complex fit-outs usually need stamped electrical drawings. Small ones can often be design-build.
