The renewal for the season was announced on April 21, 2017, during a live chat on Facebook with the cast.[1]

The writers began to officially meet to work on the season on May 30, 2017.[45][46] On July 20, 2017 at SDCC, it was announced that Alisha Wainwright was promoted to series regular as Maia Roberts.[47][48] 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.[49] The original premiere date that was announced was the 3rd of April,[50] before it was announced in December that the premiere had been moved to the 20th of March,[51] 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.[52]

Principal photography began on August 21, 2017,[53][54][55][56] took a break on December 6, 2017,[57][58] resumed on January 22, 2018,[59][60] and ran until May 2, 2018.[61][62] Additional filming took place afterwards in Paris.[63][64][65]

On June 4, 2018, it was announced that Shadowhunters was cancelled, in part due to Constantin Film losing its deal with Netflix,[66][67] 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.[68] It was announced on the 3rd of November that 3B would return on February 25, 2019.[69]
