What is a good office space utilization rate?

A good office space utilization rate is one that supports the work a space is meant to serve while keeping suitable capacity available when people need it. There is no single percentage that answers that question for every office. Define the metric, space type and observation period before setting a target.

A room used for most of the day can still have many empty seats. That is a different planning problem from a room that is rarely used at all.

Say what your utilization percentage measures

Capacity utilization describes people present relative to usable capacity. Occupied-time rate describes time with someone present relative to valid observed available time. Peak occupancy describes the highest observed concurrent count within the stated window.

These measures answer different questions. Include the denominator and working hours beside the result so another person can reproduce it. Density’s utilization metrics guide explains these distinctions.

Use a worked example before setting a target

Consider a hypothetical six-seat room available for eight hours. Two people use it for four hours, and it is empty for the remaining four. Assume complete observations and no other use.

• Its occupied-time rate is four occupied hours divided by eight available hours: 50%.
• Its average capacity utilization is eight person-hours divided by 48 available seat-hours: about 16.7%.
• Its peak observed occupancy is two people.

All three results describe the same room. Calling it “50% utilized” without naming the measure hides information that could change the design decision. The figures above are illustrative calculations, not a benchmark or customer result.

Set different expectations for different spaces

A desk neighborhood, a focus room and a large meeting room serve different needs. A focus space can be valuable because it is available when someone needs quiet. A large room may be necessary for occasional group meetings even if its average seat use is low.

Compare spaces with similar purposes before interpreting a difference as waste. Review accessibility, equipment, location, acoustics and team patterns. A room’s low use may call for a repair or a better layout rather than removal.

Protect the busiest-day experience

Look at demand by weekday and time, then examine the decision area as a whole. A weekly average can conceal congestion on a shared office day. Individual room peaks can happen at different times, so adding them together does not establish a floor’s concurrent demand.

Keep capacity changes and missing observations visible. If a sensor is unavailable, report the gap rather than treating it as evidence that the room was empty. Choose comparable periods for the baseline and follow-up.

Turn the target into an experiment

State what improvement should mean: fewer unsuccessful searches for a suitable room, better use of a desk neighborhood or enough capacity for a planned team move. Test a bounded change and measure its effect alongside employee feedback.

Density can help connect physical space use to those planning questions. Book a demo with your floor plan and proposed decision. If shared desks are part of the plan, read how to manage hot desking in a hybrid office.
