Tenant Fit-Out Electrical: Scope, Schedule & Pitfalls
In a fit-out, electrical touches nearly every other trade. Getting it right early prevents costly rework.
Updated 2026-10-15
Start with existing conditions
Survey the base-building panel capacity, metering, emergency lighting, fire alarm, and any abandoned wiring. Landlord work letters often specify what the base building provides and what the tenant pays for.
Design considerations
Typical scope items:
- Lighting and energy-code controls (occupancy, daylight, scheduling)
- Receptacle and data layouts by workstation plan
- Dedicated circuits for kitchens, IT rooms, and equipment
- Emergency and exit lighting
- Fire alarm device relocation
- Signage power and storefront lighting
Schedule realities
Electrical rough-in follows framing and precedes drywall; trim follows ceilings. Long-lead items — panels, switchgear, specialty fixtures — can drive the schedule, so order early.
