Electrical for Tenant Buildouts: What Owners and Tenants Should Plan For

A new office, a retail space, a restaurant or a medical suite all start with the same thing: electrical work that has to be planned before the walls go up. Electrical is often one of the largest parts of a tenant fit-out, and it’s one of the easiest places for schedules and budgets to slip if it’s planned late.

This guide is for owners, tenants and general contractors planning a buildout in Central and Southside Virginia.

Start With What the Space Already Has

Before design is finished, find out:

• The available capacity to the suite: the size of the tenant’s panel and feeder, and what’s left on the building’s service
• Metering: whether the space is separately metered, and what the utility needs if it isn’t
• Condition of existing wiring and panels that will be reused
• Fire alarm and emergency lighting already in place, and who maintains them

A restaurant or a medical suite can need far more capacity than the office that was there before. See checking a building’s capacity.

What Goes Into a Buildout

• Panels, feeders and circuits for the new layout
• Receptacles and dedicated circuits for equipment: kitchen equipment, copiers, servers, medical and retail equipment
• Lighting and the lighting controls the energy code expects. See LED retrofits and controls.
• Exit signs and emergency lighting
• Rooftop or split HVAC connections
• Low-voltage: data, phones, security and access control. See structured cabling for business.
• Signage power

Drawings, Permits and Inspections

Most commercial buildouts need permit drawings, and depending on the scope, electrical plans from a design professional. The local building department reviews the plans, issues the permit and inspects rough-in and final. Fire alarm work often has its own permit and inspection. Planning for review time keeps the opening date realistic.

Working With the General Contractor

On most buildouts we work as the electrical subcontractor, coordinating with the GC, the other trades and the tenant’s vendors. What makes it go well:

• Early involvement, so the electrical scope and long-lead items are in the schedule
• Clear equipment lists from the tenant, with the electrical requirements of each item
• Coordination of ceiling layouts with HVAC and sprinklers
• Prefabricated assemblies to save field time. See electrical prefabrication.

Frequently Asked Questions

Who pays for electrical in a tenant buildout?

It depends on the lease. Many leases include a tenant improvement allowance; the electrical scope and its cost should be clear before signing.

Do I need electrical drawings for a commercial buildout?

Usually yes, for the permit. Small alterations may need only a simple plan; larger work often needs drawings from a design professional.

How long does commercial electrical take in a buildout?

It follows the construction schedule, from rough-in through final, and depends on plan review, equipment lead times and inspections.

Can existing wiring be reused?

Often, if it’s in good condition, code-compliant and fits the new layout. We evaluate it early so the scope is accurate.
