Answer:
Seasonal in this code section is based on the four weather seasons in Wisconsin. An occupancy is seasonal if it extends for no more than two of those four seasons, which is a maximum time period of 6 months in any calendar year. An example of a seasonal occupancy is a summer recreational business that opens in early summer on a weekend-only basis, changes to a 7-day-a-week operation during the peak summer months, and then closes in the fall when the onset of winter conditions makes the recreational activity unlikely. A school or a school building that remains open during the nonschool-year summer period is not a seasonal occupancy.

Periodic occupancies also occur less extensively than on a year-round basis. They differ from seasonal occupancies, however, by occurring more intermittently, or repeatedly from time to time during the calendar year. An office building that is closed during weekends and open during weekdays throughout the year is not a periodic occupancy.
