Determining the Number, Size and Location of Fire Extinguishers Required
This page explains the number, size and location of fire extinguishers required throughout a condo building in Chicago. Each of the "building areas" detailed below has specific fire protection requirements and each corresponds to a matching area listed in our Fire Safety Cost Estimator tool.
Use the information below to complete the Fire Safety Cost Estimator tool, which will determine the cost required to fully service your property. This information will also help you understand the number of additional fire extinguishers, if any, that are needed to bring your building up-to-code.

In general, a condo building needs a minimum of one fire extinguisher on each floor of the building. This includes the first floor, or lobby floor, of the property. The number of extinguishers required on a specific floor is dependent on the length of the hallway or common area. The law requires that from any point on the floor, a person must be able to access a fire extinguisher in 75 feet or less.
Some smaller buildings and those with multiple tiers have a different layout consisting not of hallways, but of an interior staircase with landings. As detailed in the last example (below) a slightly different approach is used in these situations to minimize the number of extinguishers needed without compromising on fire protection.
Installation Example - Short hallway
Most floors require only a single extinguisher to provide the required level of protection. As shown in the example below, the extinguisher is installed next to the primary exit ways, and is within the 75 foot maximum travel distance from any point on the floor.
Installation Example - Mid-length hallway
In this example, the length of the hallway is 100ft, so the extinguisher cannot be installed next to the primary exit way. The extinguisher is installed in the middle of the hallway to ensure that the maximum travel distance to the extinguisher from any point within the hallway is less than 75 ft.
Installation Example - Long hallway
In the next example, the hallway is longer than 150 ft., requiring two extinguishers to be installed because a single extinguisher in the middle of the hallway would not meet the “75 foot maximum travel distance” rule. In this case, two extinguishers will be installed, an equal distance “inward”.
Installation Example - Stairwell or tiered configuration
In this final example, we will review a common configuration found in many smaller buildings and those with multiple tiers. Instead of a building consisting of multiple floors, with each floor having a long hallway with entrance doors for the units, these buildings consist primarily of an interior stairwell with multiple landings. Stated differently, the common area in the building or specific tier is made up of only a stair system.
In the example diagram below, there is a small landing consisting of the front entrance doors to two units, followed by a short set of stairs leading to an empty landing, which then leads upwards on an additional set of stairs to the next landing containing two unit entrance doors. This pattern may repeat depending on the height of the building or tier.
In these cases it is difficult to consider the small landing with entrance doors to two units as a full-fledged "floor" of the building. Given the limited amount of actual floor space within these tiered stairwells, instead of placing a fire extinguisher on each landing containing the entrance doors to the units, we will typically attempt to maximize stairwell clearance and reduce the total number of extinguishers needed by installing an extinguisher only on each of the "empty" landings. While a fire extinguisher on one floor is insufficient to provide coverage for another floor, even in a stairwell configuration, installing fire extinguishers on each empty landing ensures that for each floor, a fire extinguisher is conspicuously located and not obstructed or obscured from view, readily accessible, and immediately available, as required by law.
If empty landings do not exist, each landing with entrance doors will likely need an extinguisher. This is to avoid residents needing to travel a full flight of stairs in order to locate an extinguisher.
If your building has an elevator, the associated elevator maintenance room requires its own 10lb extinguisher, independent of any other extinguishers on the premises, even those nearby.
Similar to the normal floors of your building, the number of extinguishers required in your basement and garage depends on the “75 foot maximum travel distance” rule that was discussed earlier. For basements and garages, however, 10lb fire extinguishers are typically recommended due to the amount of square footage being protected. (If you have two separate garages, each should have its own extinguisher protection)
You must walk the area and calculate the number of extinguishers required to meet to the 75 foot maximum travel distance rule. From any point, you must be able to access an extinguisher in 75 feet or less. See the follow diagram for a sample basement.
If your building has additional common areas such as a laundry room or mechanical room, an extinguisher should be installed in each. Typically a 10lb unit will be used in these areas.
Various Types of Fire Extinguishers
As detailed on our fire extinguisher review, there are dozens of different types of fire extinguishers in the market. The requirements listed on this page are specific to dry chemical extinguishers, which are the extinguishers most commonly found in residential condo building applications.
