Charles, Oliver, and Mabel aren't done yet. Not even close. If you watched the Season 4 finale, you know the drill by now—just when you think the trio can finally grab a quiet drink at The Gooseberry, another body drops. This time, it’s personal in a way that feels shiftier than usual. We're heading into Only Murders in the Building Season 5 with more questions than we had back when Tim Kono first bit it in the elevator.
Honestly, the renewal wasn't a surprise. Hulu greenlit the fifth season back in September 2024, right as the fourth season was hitting its stride. People love this show. It’s comforting, it’s stylish, and it manages to poke fun at the true crime industrial complex without being too cynical about it. But Season 5 is shaping up to be a different beast entirely because the "Arconia universe" is expanding in ways that might actually change how the show functions.
The Arconia’s New Problem: What’s Next for the Trio?
The Season 4 finale left us with the shocking discovery of Lester. Our favorite, soft-spoken doorman. Finding him dead in the courtyard fountain wasn't just a cliffhanger; it was a gut punch. Lester has been a fixture of the building since day one. He’s the guy who sees everything and says nothing. Well, almost nothing.
In Only Murders in the Building Season 5, the mystery will almost certainly revolve around the secrets Lester was keeping. Think about it. He handles the mail. He knows who comes and goes. He sees the "Westies." He probably knew about the secret tunnels better than anyone else. If someone killed Lester, it’s likely because he finally saw something he wasn't supposed to.
Showrunner John Hoffman has hinted in several interviews, including chats with The Hollywood Reporter, that this season might lean into the idea of "The Social Club." Remember that mysterious tea shop or the mentions of elite, hidden New York societies? There’s a sense that the Arconia isn’t just an apartment building anymore—it’s a target for something much bigger and potentially more corporate.

Casting Rumors and Confirmed Returns
Steve Martin, Martin Short, and Selena Gomez are obviously locked in. You can't have the show without the chemistry of two legends and a millennial who is perpetually tired of their nonsense. But the supporting cast is where things get interesting.
- Téa Leoni as Sofia Caccimano: This is the big one. She showed up at the end of Season 4 asking for help finding her husband. She’s got ties to the "Dry Cleaning" business, which sounds like a classic mob front if I’ve ever heard one.
- The Westies: Expect to see more of the weirdos from the West Tower. Their dynamic with the main trio has become a highlight of the series.
- Jackie Hoffman as Uma: We need her insults. We live for them.
There’s also the question of the "movie" within the show. Since the film adaptation of their podcast was a major plot point in Season 4, it’s highly probable that the fallout from that production—and the actors who played them—will bleed into the new season.
Why Only Murders in the Building Season 5 Feels Different
The stakes are higher now. In the beginning, it was just three lonely people trying to find a hobby. Now, they are famous. They have a movie. They have enemies.
One thing that makes me nervous—but also excited—is the shift in tone. The show has always balanced "cozy mystery" with "dark comedy," but killing the doorman feels darker. It’s an attack on the home. It’s an attack on the safety of the Arconia itself.
There's also been plenty of chatter among fans on Reddit and social media about the "Moriarty" figure. Hoffman has teased for a couple of years that there might be a grand puppeteer behind several of the events in the building. Is Season 5 the year we finally meet the person who’s been pulling the strings since Season 1? If so, the Lester murder might just be the opening move in a much larger endgame.
Production and Timeline Expectations
So, when do we actually get to watch it?
Historically, Only Murders follows a pretty tight production schedule. They usually film in New York City during the winter and spring. Based on previous release patterns, we can reasonably expect Only Murders in the Building Season 5 to premiere sometime in mid-to-late 2025. Hulu loves a summer or early fall release for this show—it fits that "back to school/fall sweater" vibe perfectly.
The writing team usually starts breaking stories in the late fall. Given the renewal happened early, they’ve had a head start. We should expect another 10-episode run, as that’s been the standard for the series since its inception.
Decoding the Sofia Caccimano Connection
Let’s talk about Sofia. When she approached Mabel and Charles, she didn't seem like a typical fan. She seemed like someone who deals with problems—big ones. Her mention of her husband and the implication that his disappearance is linked to the Arconia is a classic noir setup.
- The Theory: Lester found out about the Caccimano family's connection to the building.
- The Evidence: Lester was always at the front desk. If someone was being moved in or out of the building covertly, he’d be the first to notice.
- The Twist: Maybe Sofia isn't looking for a victim. Maybe she’s looking for a co-conspirator.
The show excels at flipping the script. Just when you think someone is a villain, they turn out to be a pathetic loser (looking at you, Jan... okay, Jan was actually a villain, but you get my point). The writers love to play with the trope of the "femme fatale," and Téa Leoni is the perfect actor to subvert that.
What Most People Get Wrong About the Show's Formula
A lot of critics say the show is getting repetitive. "Oh, another person died in the building, how convenient." But they’re missing the point. The Arconia is a character. In Only Murders in the Building Season 5, the building's history is going to be more important than ever.
It’s not just about the murder; it’s about the architecture of secrets.
Think about the secret passageways discovered in Season 2. Think about the hidden rooms. The show is building a mythology. It’s less like Law & Order and more like a comedic Twin Peaks. Every season adds a layer to the history of the Arconia. By the time we reach the end of Season 5, we’ll likely have a much clearer picture of why this specific New York landmark is a magnet for homicide.
The Podcast Meta-Narrative
One of the most brilliant parts of the show is how it handles the podcast itself. In Season 1, it was a DIY project. Now, it’s a brand.
In the upcoming season, expect to see the trio grappling with their own success. How do you stay "indie" and "authentic" when Hollywood is calling? Mabel, especially, has been struggling with her identity. She’s the heart of the show because she’s the only one who doesn’t have a "glory days" career to fall back on. Her journey in Season 5 will likely involve finding a way to exist outside of Charles and Oliver's shadows, even as they’re tied together by another bloody mess.
Navigating the Clues: A Guide for Fans
If you're looking to get ahead of the curve, there are a few things you should keep an eye on. First, go back and watch the scenes with Lester in previous seasons. The writers love "long-game" setups. Is there a conversation Lester had with Bunny back in Season 2 that seemed insignificant then?
Second, pay attention to the background of the Arconia. The set design is littered with clues. Season 4 used a lot of film references; Season 5 might shift toward a different motif—perhaps New York history or old-school organized crime.
Actionable Insights for the Wait
- Rewatch the Season 4 Finale: Specifically, look at the items in the fountain. The creators often hide "easter eggs" that hint at the next killer's motive or identity.
- Follow the Production Leaks: Since the show films on the streets of New York, fans often snap photos of the trio in costume. Watch for new faces on set; that’s your first look at the suspect pool.
- Check the "Only Murders" Social Accounts: They often post snippets of the script or "in-universe" podcast clips that contain minor clues.
- Explore the "Moriarty" Theory: Look into the interviews with John Hoffman where he discusses the long-term antagonist. It gives you a much better sense of the show's endgame.
The mystery of Only Murders in the Building Season 5 isn't just about who killed Lester. It’s about why the Arconia won't let these three people go. Whether it’s the Caccimano family, a hidden social club, or a long-lost relative, the truth is lurking in the vents. We just have to wait for the podcast to drop.
Keep your eyes on the official Hulu press releases for the confirmed premiere date, which usually lands on a Tuesday. Until then, stay out of the secret elevators. Or don't. It makes for a better story anyway.
