## Production

The renewal for the season was announced on April 21, 2017, during a live chat on Facebook with the cast.

The writers began to officially meet to work on the season on May 30, 2017. On July 20, 2017 at SDCC, it was announced that Alisha Wainwright was promoted to series regular as Maia Roberts. On October 7, 2017 at NYCC, it was announced that Freeform officially ordered the additional 10 episodes (3B) to air in the summer of 2018. The original premiere date that was announced was the 3rd of April, before it was announced in December that the premiere had been moved to the 20th of March, two weeks earlier than the original plan. Freeform's press release for its May 2018 lineup announced that the first half of the season (3A) would end with a two-hour mid-season finale on May 15, 2018.

Principal photography began on August 21, 2017, took a break on December 6, 2017, resumed on January 22, 2018, and ran until May 2, 2018. Additional filming took place afterwards in Paris.

On June 4, 2018, it was announced that *Shadowhunters* was cancelled, in part due to Constantin Film losing its deal with Netflix, and that 3B would return in spring 2019. An additional two episodes, to air as a two-hour series finale, was ordered in order to give closure to the storyline. It was announced on the 3rd of November that 3B would return on February 25, 2019.
