Area of Refuge: Requirements, Signage, and Communication

Area of refuge requirements come from two overlapping sources: International Building Code (IBC) Section 1009 and the ADA Accessibility Standards. Together they say that on any floor above or below the level of exit discharge in a building without a full automatic sprinkler system, there must be a fire-rated space where people who cannot use stairs can wait for rescue, along with a two-way communication system, code-compliant signage, and enough wheelchair spaces to match the floor’s occupant load.¹

When an Area of Refuge Is Required

The trigger is the combination of two conditions. First, the building has floors above or below the level of exit discharge. Second, it does not have a code-compliant automatic sprinkler system throughout. When both are true, those floors need areas of refuge as part of the accessible means of egress. Accessible spaces must be served by at least one accessible means of egress, and where a floor requires more than one means of egress, each accessible portion must be served by at least two.²

Several building types are exempt even without full sprinklers, and buildings equipped throughout with a compliant sprinkler system are the most common exemption of all.¹ Other exemptions include:

Open parking garages, where the open-air design lets smoke dissipate.
Apartment and residential buildings, where dwelling units are treated as points of safety. In some code editions, a fire-rated corridor providing direct access to a compliant elevator can substitute for a traditional refuge.
Detention and correctional facilities, where staff-controlled evacuation replaces self-directed egress.
Open exit stairways connecting floors in buildings with sprinklers meeting NFPA 13.

Because of the sprinkler exemption, many newer commercial buildings have no dedicated refuge rooms. The first question on any project is whether a full sprinkler system removes the requirement entirely.

Where the Space Must Be Located

An area of refuge has to sit directly along an accessible route leading to an exit. In most buildings it lives inside an enlarged stairwell landing or next to an elevator lobby so rescuers can find it without moving deep into the interior.¹

Where a stairwell landing doubles as the refuge, the landing has to be large enough for the required wheelchair spaces without narrowing the stairway below its minimum width. Wheelchair spaces cannot overlap the required stairway width and cannot intrude into a door swing. The IBC ties maximum travel distances to the means of egress overall, not to the refuge alone, so in practice the space sits at or inside the stairwell enclosure rather than at the far end of a corridor.

Size and Number of Wheelchair Spaces

Each wheelchair space must measure at least 30 inches wide by 52 inches deep. The count is tied to the occupant load of the floor served: one wheelchair space for every 200 occupants, or portion thereof.² A floor with 350 occupants needs two spaces: one for the first 200, one for the remaining 150.

Any evacuation chairs or stair-descent devices stored near the refuge cannot block the means of egress.³ A device leaning against a stairwell wall that reduces effective stairway width below code minimums is a common inspection finding.

Two-Way Communication

Every area of refuge needs a two-way communication device that produces both audible and visible signals.² The dual-signal rule means a person with a hearing impairment sees a light confirming the message was received, and a person with a vision impairment gets audible confirmation. A typical installation is a push-button panel with indicator lights at the refuge, wired to a matching panel at the building’s fire command center.

Where the System Has to Connect

The device must connect to the fire command center or another central control point approved by the fire department. If that point is not staffed around the clock, the system must have automatic telephone dial-out to an approved monitoring station or to 911 dispatch. This is where smaller buildings sometimes fail compliance: the hardware is installed, but no monitoring contract is in place, so the panel is connected to nothing useful during an actual emergency.

Backup Power

The communication system has to keep working during a power failure. IBC Table 2702 sets a minimum backup duration of 24 hours on battery power, or 4 hours on a generator. NFPA 72 governs the design and installation of these systems and adds pathway survivability requirements so wiring and equipment continue to function during fire exposure. Survivability levels correspond to the building’s fire-resistance rating.

Posted Instructions

Instructions for using the device must be posted next to it. They have to explain how to request help and identify the specific location within the building. Without those directions, someone using the device for the first time is trying to figure out an unfamiliar panel in a stairwell that may already be filling with smoke.

Signage

Signs identifying an area of refuge must be posted at every door leading into the space, and each sign must display the International Symbol of Accessibility together with the words “AREA OF REFUGE.”⁴ Because these designate a permanent room or space, they must be tactile. That means raised characters with Grade 2 Braille, mounted 48 to 60 inches above the floor so they can be located by touch.⁵

Directional Signs Along the Route

Directional signs pointing toward an area of refuge follow different rules. They do not have to be tactile, but they must use high-contrast characters on a non-glare background, with minimum character heights based on viewing distance, mounted at least 40 inches above the floor.⁵ Character style must be conventional. Italics, script, and heavily decorative fonts do not qualify.

Emergency Illumination

Both identification signs and directional signs must remain legible when main power fails, which usually means internal or external illumination connected to the building’s emergency power system. Burned-out bulbs and dead batteries on sign lighting are among the most common findings during annual fire marshal inspections.

Fire and Smoke Protection

The enclosure has to keep heat and toxic gases out long enough for responders to arrive. When the refuge sits inside a stairway enclosure, it inherits that enclosure’s fire-resistance rating, which varies by building height and construction type. For exterior areas used as assisted rescue points, the IBC requires at least a one-hour fire-resistance rating on the wall separating the exterior platform from the interior, extending at least 10 feet above the floor of the rescue area.⁶ Doors into the space must carry matching ratings and close automatically.

Where the refuge is enclosed by smoke barrier walls rather than full fire barrier walls, those barriers must form a continuous membrane that terminates at a fire barrier with at least a one-hour rating or at an exterior wall. Some jurisdictions also require pressurized air systems that push clean air into the refuge to keep smoke out when doors open. Compromised assemblies, such as unsealed penetrations for conduit or ductwork, can result in a building being deemed unfit for occupancy until repairs are complete.

Occupant Evacuation Elevators as an Alternative

IBC Section 3008 lets buildings install occupant evacuation elevators as part of the egress system. The elevator lobby on each floor must hold one wheelchair space (30 by 52 inches) for every 50 occupants served, plus standing room at 3 square feet per person for at least 25 percent of the floor’s occupant load. Each lobby needs a two-way communication system meeting the same standards as an area of refuge.

These elevators do not automatically remove the need for areas of refuge in every design, but in certain high-rise configurations they can replace the requirement for an additional exit stairway.

Maintenance and Testing

NFPA 72 requires two-way communication systems to be inspected and tested under its Chapter 14 protocols. Ancillary functions that do not impair the core emergency communication system must be tested at least annually. Fire marshals typically expect documentation showing that someone has pressed the call button, verified that the signal reaches the fire command center or monitoring station, confirmed the backup power engages, and checked that indicator lights work at both ends.

Signs, emergency lighting, door closers, and fire-rated assemblies need periodic inspection as well. Self-closing doors propped open with wedges are a recurring problem: a fire-rated door held open is functionally the same as no door once smoke starts moving. Organized, current maintenance records are the simplest way to show compliance during an inspection and to defend against liability if an incident occurs.
