9JKL is an American sitcom television series that was created and executive produced by Dana Klein and Mark Feuerstein, loosely based on the life of the couple, who are married in real life.
Josh Roberts, a divorced actor whose TV series was recently cancelled, moves back to New York City and lives in apartment 9K. His family lives in adjacent apartments: his parents live in 9J, while his brother, sister-in-law, and their newborn baby live in 9L. This unique situation prompts Josh to try and set boundaries while reconnecting with his family members.
The show is loosely based on Feuerstein's experiences while shooting the USA Network series Royal Pains; in real life, however, Feuerstein lived with his wife, 9JKL executive producer Dana Klein, while living next to his own family.
