Only Murders in the Building is confirmed to be relocating its writers' room from Los Angeles to New York, according to a Deadline report, even before the show has been officially renewed for a seventh season. The move signals that the production is preparing for continuity beyond the upcoming sixth season, reinforcing expectations that a formal renewal announcement is imminent given the show's consistent success for Hulu since its 2021 debut.

Season six, premiering on Hulu on 8 December, sees stars Steve Martin, Martin Short, Selena Gomez and Meryl Streep return as the trio's investigation shifts from New York's Arconia building to London, where they must solve the murder of Cinda Canning amid a cast of English eccentrics, with guest stars including Tina Fey, Olivia Colman, David Tennant, Nicola Coughlan and Martin Freeman. The series has been a ratings powerhouse throughout its run, with its 2021 premiere earning 719 million minutes viewed in its debut week and the season five finale still ranking as the seventh most-watched streaming original that week.
