NYC Housing Maintenance Code §27–2040: Exterior Lighting Requirements for Multiple Dwellings

New York City Housing Maintenance Code §27–2040 requires owners of multiple dwellings to provide proper exterior lighting near building entrances, yards, and courts to help maintain safe living conditions for tenants and visitors. Under this law, owners must install and maintain lighting fixtures at or near the front entrance of residential buildings and ensure that the required illumination remains on from sunset until sunrise each day. The amount of lighting required depends on the width of the building frontage and entrance configuration. Larger buildings and wider entranceways require greater illumination and, in some cases, lighting fixtures installed on both sides of the entrance.

The code also requires owners to provide lighting in all yards and courts of multiple dwellings. These outdoor areas must contain one or more fixtures providing at least one hundred watts of incandescent illumination or its modern equivalent. Proper lighting in exterior spaces helps improve visibility, reduce nighttime hazards, increase security, and assist emergency responders when accessing the property after dark. Building owners are responsible not only for installing these lights but also for maintaining them in safe and working condition throughout the year.

Failure to comply with NYC §27–2040 may result in Housing Preservation and Development (HPD) violations, tenant complaints, and potential liability exposure if inadequate lighting contributes to accidents or unsafe conditions. Many property owners now use energy-efficient LED dusk-to-dawn fixtures or automatic photocell lighting systems to help maintain continuous compliance. Owners should routinely inspect exterior fixtures, replace burned-out bulbs promptly, and verify that all entranceways, yards, and courts remain properly illuminated during nighttime hours.

Understanding NYC Housing Maintenance Code §27–2040

Lights Near Entrance Ways and in Yards and Courts of Multiple Dwellings

NYC Housing Maintenance Code §27–2040 requires owners of multiple dwellings to provide adequate exterior lighting for building entrances, yards, and courts. The purpose of this law is to improve tenant and visitor safety, reduce hazards and criminal activity, and ensure safe access to and from residential buildings during nighttime hours.

This section applies primarily to “multiple dwellings,” which generally means residential buildings occupied by three or more families living independently.

Section (a) — Entrance Lighting Requirements

1. Owner Must Install and Maintain Exterior Entrance Lighting

The law requires the owner to:

• Install lighting fixtures near the front entrance of the building.
• Maintain those fixtures in working condition.
• Keep the required lights illuminated every night from sunset until sunrise.

This means the lights cannot simply be installed once and ignored. Burned-out bulbs, broken fixtures, disconnected wiring, or inadequate lighting can result in violations.

Minimum Lighting Requirements by Building Width

The law measures lighting requirements partly by the width (“frontage”) of the building.

Buildings With Frontage Up to 22 Feet

If the building frontage is:

• 22 feet wide or less

the owner must provide lighting equal to:

• 100 watts incandescent illumination minimum
  or
• an equivalent modern lighting output.

What “Equivalent” Means

Because incandescent bulbs are now uncommon, LED or fluorescent fixtures are permitted if they produce similar brightness.

Examples of approximate equivalents:

The important factor is actual light output, not electrical consumption.

Buildings With Frontage Over 22 Feet

If the building frontage exceeds:

• 22 feet wide

the owner must provide:

• 200 watts incandescent illumination minimum
  or equivalent.

This requirement recognizes that larger buildings need broader illumination coverage.

Additional Rule for Large Entrances

If BOTH conditions exist:

1. The building frontage exceeds 22 feet, AND
2. The entrance doors together exceed 5 feet in total width,

then the owner must install:

• at least two lighting fixtures
• one on EACH side of the entrance
• with a combined illumination equal to:
  • 300 watts incandescent illumination or equivalent

Purpose of This Rule

This provision prevents dark areas around wider entrances and ensures even lighting coverage for larger apartment buildings.

Lighting Fixture Placement

The owner may choose:

• fixture style,
• design,
• exact placement,
• mounting type,
• decorative appearance,

provided the minimum illumination standards are met.

However, the NYC Department of Housing Preservation and Development (HPD) may regulate:

• maximum fixture height,
• distance from entrance,
• electrical safety,
• installation methods.

Required Operating Hours

The code specifically states:

• lights must remain ON from:
  • sunset
  • until sunrise the following day.

This means:

• motion-only lighting may not satisfy the requirement if illumination is insufficient,
• lights cannot be manually shut off overnight,
• automatic photocells or timers are commonly used for compliance.

Common Violations Under Section (a)

Owners may receive violations for:

• burned-out bulbs,
• insufficient brightness,
• non-working fixtures,
• dark entranceways,
• missing lights,
• disconnected electricity,
• improper placement,
• failure to illuminate all night.

HPD inspectors commonly issue violations if the entrance appears unsafe or inadequately lit.

Section (b) — Yard and Court Lighting Requirements

Lighting Required in Every Yard and Court

The owner must also provide lighting in:

• rear yards,
• side yards,
• inner courts,
• shared outdoor spaces.

The code requires:

• one or more fixtures,
• equal to at least:
  • 100 watts incandescent illumination
  • or equivalent.

Placement of Yard and Court Lights

The NYC department may prescribe fixture locations.

This means inspectors may require lights to be positioned where:

• dark areas exist,
• pathways are unsafe,
• tenants travel regularly,
• security concerns arise.

Yard and Court Operating Hours

Just like entrance lights:

• yard and court lights must remain illuminated:
  • from sunset to sunrise.

Why This Code Exists

The law is intended to:

• improve tenant safety,
• reduce slip-and-fall hazards,
• deter crime,
• improve emergency access,
• help firefighters and emergency responders,
• ensure safe nighttime access to the property.

Exterior lighting is considered a basic housing maintenance obligation in NYC.

Practical Compliance Recommendations for Owners

Owners commonly maintain compliance by:

• using LED dusk-to-dawn fixtures,
• installing photocell sensors,
• inspecting bulbs weekly,
• keeping fixtures clean,
• replacing damaged lenses,
• ensuring no dark spots exist near entrances,
• upgrading old low-output fixtures.

Examples of Compliance

Example 1 — Small Building

A 20-foot-wide 3-family building may comply with:

• one bright LED fixture near the entrance
• producing equivalent brightness to 100 watts incandescent.

Example 2 — Large Apartment Building

A 40-foot-wide apartment building with double entrance doors may require:

• two wall-mounted fixtures,
• one on each side of the entrance,
• combined brightness equivalent to 300 watts incandescent.

Potential Consequences of Non-Compliance

Failure to comply may result in:

• HPD violations,
• housing court enforcement,
• tenant complaints,
• DOB or electrical safety issues,
• liability exposure if injuries occur in poorly lit areas.

Poor lighting can also increase exposure to negligence claims after accidents or criminal incidents.

Important Notes About “Equivalent Illumination”

The law was written when incandescent bulbs were standard. Modern LED fixtures are generally acceptable if they provide comparable brightness.

Approximate reference:

Many owners now use commercial LED wall packs or dusk-to-dawn fixtures to meet these requirements efficiently.
