Any building pursuing a BOMA BEST certification must have been in operation for at least 12 months.

Buildings with occupancy rates below 50% are only eligible for the BOMA BEST Baseline Certified.

To be eligible for a higher level of certification (Bronze, Silver, Gold or Platinum), a building must have a minimum occupancy rate of 50% for 12 consecutive months, at a minimum.

The occupancy rate is based on the percentage of the net leasable area that is actively leased. This is different from the occupant density, which is based on the percentage of occupants who are actually inside the building on a given day.

Occupancy rate is based on the percentage of the gross leasable area that is actively leased.

Vacancy rate refers to the percentage of the gross leasable area that is not leased.

This is different from the occupant density which is based on the percentage of occupants actually inside the building on a given day.

Our eligibility criteria apply to % of building leased.

If the building’s occupancy rate (not occupant density) has been 50% or higher for the past 12 months, the building is eligible for BOMA BEST Bronze, Silver, Gold or Platinum certification levels.

If the building’s occupancy rate (not occupant density) has been below 50% for the past 12 months, the building is eligible for the BOMA BEST Baseline Certified level only.

(Average actively leased area in past 12 months / Total Net Leasable Area) x 100
