  Production
  On April 1, 2016, the series was renewed for a thirteenth and fourteenth season, which tied it with The Adventures of Ozzie and Harriet as the longest-running (in number of seasons) live-action sitcom in American TV history.
  
  In March 2017, following the twelfth season finale in which Glenn Howerton's character was seemingly written off the show, Howerton expressed doubt in his return for the thirteenth season, describing it as "partially a creative and personal decision." He also suggested that the show would take an "extended hiatus" in order to accommodate the cast's other projects. In late April, Kaitlin Olson confirmed Sunnys extended hiatus ahead of the thirteenth season due to the cast's busy schedules. In August 2018, Rob McElhenney confirmed that Howerton is "in pretty much every episode" of the season. Howerton appeared in six of the season's ten episodes, but had no writing credits.
