A. You don't see the exterior of the studio in this series. but you see the interior in virtually every episode of Dexter: Resurrection, with sets built to recreate assorted interior locations,
 
Although they film most of the scenes out on location for this series, if it's an interior scene, there's a good chance that it was filmed on a set inside a studio soundstage.

A. They filmed Dexter: Resurrection at the Great Point Studios in Yonkers, New York. 

Although Great Point owns the studios that they build, the anchor tenant at the Yonkers studios is Lionsgate Films, so Lionsgate acquired the naming rights to the studio, and while they are there, the largest of the Great Point studios in Yonkers is known as Lionsgate Studio. 
 
Great Point Studios is spread out over a number of different buildings and campuses in Yonkers, most of them clustered within a few blocks of each other in the same general part of Yonkers, just a block or two from the Hudson River.
 
Great Point facilities in Yonkers include studio facilities at:
  

• 28 Wells Ave, Yonkers, NY: the main Lionsgate studio campus. 
  
  

StreetView

•  90 Warburton Avenue:  A separate building just north of the main campus.  

 
StreetView

• 95 Woodsworth Ave: now a temporary “pop up” studio, one block north of the main studio (which is right next to the railroad tracks where they filmed the scene of the teens discovering the decapitated body of the Dark Passenger killer's victim) . But Great Point's plans call for that pop-up to be replaced by permanent studio buildings that will occupy all four corners of the intersection of Woodsworth Avenue & Babcock Place.

( Great Point also has a separate studio at 1050 North Broadway, but that is two and a half miles north of the Lionsgate Studio, and it is leased by Mediapro, not Lionsgate, so I don't think Dexter: Resurrection is involved with that branch of the studio . )

And within each studio lot are multiple soundstages, where they actually do the filming. Most are 20,000 square feet, with other stages measuring in  at 30,000 and 10,000 feet. 

Here is a map of the various Great Point Studio locations:

With past Dexter studios in Hollywood, I was able to give you a history of the studio and an extensive list of movies and TV shows that were produced there over the decades. But that’s not possible with this Lionsgate / Great Point studio, because it’s brand new. 
 
They just opened the studio in January 2022.
 
But they still have a few notches on their belt already. Other than Dexter: Resurrection, they have also filmed scenes from The Gilded Age and Severance at the new Lionsgate Studio.
 
Dexter has always shot  a fair number of their scenes near their studios. There is a simple, practical reason for that: if a scene doesn't require a specialized setting, and a more generic location is available near the studio, it doesn't make much sense to travel farther away than one has to for a location shoot.

So when the original Dexter series was filming in Los Angeles, and their studio was Sunset-Gower in Hollywood, even though they shot most of their scenes in Long Beach, they still shot a fair number of them right around the studio, including at a number of residential houses that were right across the street from the studio. And when they did Original Sin, and they were operating out of  the Studio City studio in the San Fernando Valley, they filmed quite a large number of those Original Sin scenes in the Valley, including the Morgan family home and Deb's high school.  So it's not surprising that now that they have moved to New York, and their new studio is in Yonkers, they've been filming quite a few of their scenes right there in Yonkers.

Scenes shot in Yonkers, relatively close to the studio, include:

The NYPD impound lot.
Blessing Kamara's house.
The Police Station.
The discovery of the rideshare driver's body.
Harrison hallucinating a bloody Ryan.
The Alley where Dexter grabs Vinny, the landlord.
Dexter releasing Charley after abducting her.
and Joey Quinn at a crime scene in Miami Beach.  

 
Update:  As of January 2026, news is that Dexter: Resurrection will be moving to a new studio for its second season. It will be a brand new studio just opening, named Sunset Pier 94 Studios, located on a Hudson River pier on the west side of Manhattan Island. 
The advantage is obvious. Their studio for the first season required them to commute all the way up to Yonkers on a regular basis, despite the fact that most of their filming took place on Manhattan Island. And this new studio is right there on Manhattan, at the west end of 12th Ave, just a mile west of Times Square, the heart of NYC.  I will be creating a new page about the new studio in time for the second season of Resurrection, which begins filming in April 2026, and will air its first new episodes in October.
