How the Occupancy Counter Works
The Occupancy Counter calculates how many people are inside a space by adding each entry and subtracting each exit you tap in. The live occupancy number never drops below 0.
- Set the opening count: Enter the number of people inside at the start, usually 0 or the staff count.
- Tap + for each entry: Each arrival raises occupancy by 1.
- Tap − for each exit: Each departure lowers occupancy by 1.
- Read live occupancy: The large number shows people inside right now and the highest value reached today.
Occupancy Counter Formula
The Occupancy Counter value equals the opening count plus entries minus exits. Peak occupancy equals the highest value reached during the period.
- Opening
- People inside at the start
- Entries
- Arrivals tapped in
- Exits
- Departures tapped in
Example: A gym opens with 3 staff inside. By 18:00 it logs 145 entries and 92 exits. Occupancy = 3 + 145 − 92 = 56 people.
Occupancy Counter Reference Table
The Occupancy Counter conversion table converts floor area into a typical occupancy limit using common occupant load factors. Local fire codes set the official values.
| Use of space | Load factor (ft² per person) | Load factor (m² per person) | Limit for 1,000 ft² (92.9 m²) |
|---|---|---|---|
| Standing assembly | 5 | 0.46 | 200 |
| Seated assembly, loose chairs | 7 | 0.65 | 142 |
| Retail sales floor | 60 | 5.6 | 16 |
| Gym or exercise room | 50 | 4.6 | 20 |
| Office | 150 | 13.9 | 6 |
| Restaurant dining | 15 | 1.4 | 66 |
About the Occupancy Counter
An Occupancy Counter is a live tally of the number of people inside a building or room at one moment. The count rises with entries and falls with exits.
Occupancy limits come from fire and building codes. The International Building Code (IBC) sets occupant load factors per floor area, such as 5 ft² (0.46 m²) per person for standing crowds, and venues post the resulting limit near the entrance.
Ways to Use the Occupancy Counter
There are 5 main uses of the Occupancy Counter, including fire code compliance and crowd control.
- Fire code compliance: Venues keep the number inside below the posted limit.
- Crowd control: Event staff pause entry when the room nears capacity.
- Pool safety: Lifeguards keep swimmer numbers within bather load limits.
- Shop capacity: Stores cap shoppers inside during busy sales.
- Evacuation planning: Wardens know how many people to account for during a drill.
