Commercial Lighting Contractors for Tenant Improvements
Lighting layouts, LED fixtures, and controls that meet the energy code and make the space work.
Lighting shapes how a space looks, how comfortable it is to work in, and how much it costs to run. In a tenant improvement it is also one of the most heavily regulated parts of the electrical scope, because energy codes set limits on lighting power and require automatic controls.
Our network connects owners and tenants with licensed lighting and electrical contractors who plan fixtures, controls, and emergency lighting together so the space passes inspection and performs well after move-in. For the full electrical scope, see our commercial electrical page.
What a Lighting Scope Includes
Lighting work on a typical build-out covers:
- Reflected ceiling plans and fixture layouts
- LED fixture selection for each room type
- Lighting controls, sensors, and dimming
- Emergency and exit lighting along egress paths
- Exterior, storefront, and sign lighting where included
Planning these together avoids gaps between the designer, electrician, and fixture supplier.
Designing for the Space
Good lighting starts with how each area is used:
- Light levels suited to offices, retail, labs, and warehouses
- Glare control at screens and workstations
- Color temperature and color rendering for retail and medical spaces
- Accent and display lighting for merchandise and brand areas
- Coordination with ceilings, ductwork, and sprinklers
Fixture choices that look right on a cut sheet can still fail in the room if the layout is not coordinated.
Energy Code Requirements
Commercial lighting must meet the adopted energy code, such as the IECC, ASHRAE 90.1, or California’s Title 24 Part 6. Requirements commonly include:
- Limits on installed lighting power for each space type
- Occupancy or vacancy sensors in many rooms
- Automatic shutoff and time-based controls
- Daylight-responsive controls near windows and skylights
- Functional testing of controls before final inspection
Energy compliance forms are part of the permit set, so the lighting design has to be settled before submittal.
Lighting Controls
Controls are where most lighting inspections and complaints happen:
- Wall-box sensors and dimmers for small rooms
- Networked or wireless control systems for larger floors
- Scheduling and override settings for after-hours use
- Integration with building automation where required
- Programming and commissioning before move-in
Controls that are installed but never programmed waste energy and frustrate occupants.
Emergency and Exit Lighting
Life safety lighting is required along exit paths:
- Exit signs at required locations and direction changes
- Emergency illumination of corridors, stairs, and exits
- Battery units or emergency circuits and inverters
- Exterior egress lighting at exit discharge
- Testing and documentation for the fire inspector
Emergency lighting is checked at final inspection and must work on loss of normal power.
Retrofits, Lead Times, and Rebates
Practical issues often decide lighting schedules and budgets:
- LED retrofits of existing fixtures where the layout still works
- Fixture lead times that can affect the finish schedule
- Approved substitutions when specified products are delayed
- Utility rebate programs for efficient fixtures and controls
- Attic stock and spare parts for future maintenance
Checking for utility rebates before ordering can help offset the cost of better fixtures and controls.
Frequently Asked Questions
Do I have to upgrade lighting during a tenant improvement?
When lighting is altered, energy codes usually require the new or altered lighting to meet current power and control rules. How much must change depends on the scope and the local code.
Are occupancy sensors required?
In many spaces, yes. Most current energy codes require automatic controls such as occupancy or vacancy sensors in offices, conference rooms, restrooms, and similar spaces.
Are there rebates for LED lighting?
Many utilities offer rebates for efficient fixtures and controls. Programs and amounts change often, so check with the local utility before buying.
