Set in the fictional city of Royal Woods, Michigan, The Loud House centers on 11-year-old Lincoln Loud, who lives in a house with his ten sisters - bossy eldest sister Lori, unintelligent Leni, aspiring rock star Luna, jokester and comedian Luan, energetic athlete Lynn Jr., gloomy emo Lucy, care-free mud-loving tomboy twin Lana as opposed to her picture-perfect beauty pageant twin Lola, intellectual genius Lisa, and baby Lily. While being true that his room is a closet, there's only one bathroom, and his sisters drive him crazy, Lincoln always finds the solution with the help of his best friend Clyde McBride—one problem at a time. Each episode has Lincoln speaking to the viewer about life lessons within your family—especially when it's big.
The series was created by veteran animator Chris Savino and was inspired by his childhood. During early development, Savino originally wrote the characters as rabbits, with the number of siblings being 26. Someone at Nickelodeon suggested that the characters instead be humans, an idea that Savino initially declined on. He eventually relented after thinking about it some more and also reduced the number of kids to 11. As a nod to the original idea, Lincoln's stuffed bunny, Bun-Bun, is modeled after Lincoln's original rabbit design. In addition, "White Hare" involved Lincoln as a rabbit named Warren—a reference to the show's original concept; Warren having 25 sisters are retained. Not featured in the concept was Clyde's beaver counterpart Danny.
The first season originally consisted of 13 episodes (26 segments in total), but Nickelodeon changed it to 26 (52 segments in total).
Two episodes ("A Tale of Two Tables"/"The Sweet Spot" and "Hand-Me-Downer"/"Sleuth or Consequences") were released digitally on Nick.com, the Nick app, Nick's video-on-demand service and digital platforms in April 2016, a month before the series' official debut on May 2.
Brand-new episodes would air every week at 5:00 pm EST, before a brand-new episode of another show.
The second season was greenlit on May 25, 2016 and consists of 26 episodes, beginning on November 9, 2016 with "Intern for the Worse"/"The Old and the Restless" and ended on December 1, 2017 with "Snow Way Out"/"Snow Way Down".
Jam Filled Entertainment, a Canadian animation studio based in Ottawa that was owned by Boat Rocker Media, provides the animation for the series. The animation is done by using Toon Boom Harmony.
Every episode in the first season was directed by Chris Savino; "The Price of Admission" and "One Flu Over the Loud House", as well as the second season's "The Old and the Restless", "Vantastic Voyage", and "Patching Things Up" were co-directed by Kyle Marshall. However, not all episodes were directed by Savino; both digital shorts, "Slice of Life" and "Deuces Wild!" (Savino only wrote the shorts), and a few season two episodes were directed solely by Marshall.
On October 19, 2017, Nickelodeon fired Savino due to allegations of sexual harassment, and continued to work on the show without him. Michael Rubiner will become the main showrunner and Kyle Marshall will be the main director, with Amanda Rynda, a replacement for Savino, directing "Selfie Improvement". A few season three episodes directed by Savino were released after his termination, as they were produced prior; Savino's last episode to direct for the series was "What Wood Lincoln Do?"
