Occupancy permits apply when you change an occupancy or change a structure. If there is no change, the prior occupancy permit would apply.

the church hall would be an assembly occupancy, the school would be an education occupancy and the building would be a mixed occupancy.

Divide current occupancy by the total possible occupancy and multiply by 100.

For example:

If a facility has a total possible occupancy of 100 and the current occupancy is 75 then the occupancy rate is 75%.

75 / 100 * 100 = 75 %

If you do not multiply by 100 then you have the answer as a decimal fraction.
