Common Area Lighting Upgrades for Apartment Buildings

Hallways, stairwells, entries and parking areas are the parts of an apartment building every tenant uses daily. When lights are dim, flickering or out, tenants notice quickly, and the lighting becomes a safety and maintenance issue. Upgrades can fix these problems while lowering energy use and service calls.

This guide explains how to plan common-area lighting upgrades in occupied multi-family buildings, including fixture selection, controls, emergency lighting and scheduling. For an overview of the electrical scope, see our page on common area lighting and electrical work.

Why does common-area lighting affect safety?

Stairwells and hallways are places where falls happen, especially at night and in winter, when tenants carry snow and salt inside. Even light levels without dark spots help tenants see steps, door edges and landings. Entries and parking lots need enough light for tenants to see people and vehicles, read keys and locks, and walk on icy pavement.

Lighting is also tied to egress. The path to an exit must remain visible during a power outage, which is why many buildings require battery-backed emergency lights and exit signs. Replace failed lighting promptly and treat egress lighting as a life-safety system, not as a convenience.

What should you inspect before planning an upgrade?

Walk the building at night and during the day. Mark each fixture type, lamp type, mounting height, condition and control method. Note dark areas, glare, burned-out fixtures, damaged lenses, water inside outdoor fixtures, and fixtures that tenants report as unreliable.

• Fixture and lamp types: fluorescent tubes, compact fluorescent lamps, metal halide, high-pressure sodium or LED.
• Controls: manual switch, timer, photocell or occupancy sensor, and whether each works correctly.
• Circuit and panel loading, and whether common-area loads are on the house meter.
• Wiring condition at fixtures, especially exterior boxes exposed to Minnesota freeze-thaw cycles and moisture.
• Pole bases and parking lot poles for rust, damage and loose covers.

This survey becomes the scope of work. A licensed contractor can compare options and quote them for commercial lighting projects of this type.

Is LED conversion worth it for hallways and parking lots?

LED fixtures use less electricity than fluorescent, metal halide and high-pressure sodium sources for the same light output, and they usually last longer between replacements. That reduces both the utility bill and the number of times maintenance staff must change lamps on ladders or in lifts. Costs depend on the fixture style, whether existing fixtures can be retrofitted or replaced, mounting height, and how much wiring or pole work is needed.

Ask your electric utility whether it offers lighting incentives for multi-family properties before ordering fixtures. Programs may require approval before purchase, so confirm current terms with the utility.

Retrofit lamps versus new fixtures

Retrofit kits and LED tubes keep the existing housing and cost less to install, but old housings, lenses and ballasts may be near the end of life. Some LED tubes require rewiring the fixture to bypass the ballast. A full fixture replacement provides new wiring connections, a sealed housing and a rated warranty from the manufacturer, which is often the better choice for exterior and wet locations. Choose fixtures listed for damp or wet locations when they are installed outdoors.

Color temperature and light levels

Select a color temperature that suits the area. Many apartment buildings use neutral white for hallways and exterior areas. Avoid over-lighting, which wastes energy and creates glare. For exterior areas, choose fixtures that direct light downward and limit light spilling into tenant windows.

Which controls work best: photocells, timers or occupancy sensors?

In hallways and stairwells that people use at all hours, many designs keep a low level of light on and raise it when someone approaches. This reduces energy while avoiding fully dark spaces. Do not let an occupancy sensor turn off the only light in an exit path.

How do emergency and exit lighting fit into the upgrade?

When fixtures, ceilings or circuits are changed, emergency lighting must be reviewed too. Some buildings use fixtures with built-in battery backup, and others use separate battery units or a central inverter. Conversion to LED can change which units are needed, and a control that switches a fixture off must not disable its emergency function.

NFPA 101 calls for functional tests of battery-operated emergency lights at least monthly for at least 30 seconds and annually for at least 90 minutes, and Minnesota sources cite related State Fire Code intervals. Test the lights after the work is finished and record the results. See our overview of emergency and exit lighting for detail.

How do you upgrade lighting with tenants still in place?

Plan the work in zones, such as one stairwell or one floor corridor at a time, and give written notice with the dates, times and any planned outage. Work during daytime hours when possible, and keep egress routes lit. If power to a corridor must be off, provide temporary lighting and keep it clear of walking paths.

• Notify tenants in writing before work begins, and post notices at the building entrance.
• Stage materials away from exits and keep stairs and hallways clear of cords and tools.
• Replace fixtures and test before moving to the next zone, so no area stays dark overnight.
• Schedule exterior work for dry weather, and plan parking lot work so tenants can still park.
• Complete a walk-through after dark to check coverage and controls, then adjust.

For buildings with a maintenance program, align lighting upgrades with the recurring tasks described in our guide to property management electrical maintenance. Upgrading while crews are already on site reduces repeat visits.
