Construction on the massive Monsters, Inc. expansion at Disney’s Hollywood Studios continues to move forward, and a newly filed permit provides another indication of the work taking place behind the construction walls.
Walt Disney Imagineering has filed a new Notice of Commencement for the installation of scenic set elements at an address associated with the Monstropolis construction project.
The filing, reported November 12, 2026, identifies Mecca Productions, Inc. as the contractor and describes the planned work as “Install set elements.”
The listed address is 253 S Studio Drive, which has been associated with construction activity in the area of the upcoming Monsters, Inc. Door Vault roller coaster.
Although the filing does not explicitly identify the coaster or specify which scenic elements are being installed, its location suggests that the work could be connected to the attraction.
The permit represents another concrete development in a project that has seen substantial construction progress throughout 2026.
What Does the New Monsters, Inc. Permit Reveal?
The Notice of Commencement identifies Walt Disney Imagineering as the entity overseeing the work, with Mecca Productions contracted to install set elements.
These types of filings are routinely associated with construction and refurbishment projects throughout Walt Disney World.
Set installation can encompass a wide variety of themed elements, from decorative architectural features to scenic components that help establish an attraction’s environment.
However, the description in this particular filing is relatively broad.
It does not identify specific props, show scenes, ride effects, or other components being installed.
It also does not establish that the installation has already begun or that any particular stage of interior construction has been completed.
The significance of the permit lies in the newly documented scope of work and its apparent connection to the ongoing Monstropolis expansion.
Monsters, Inc. Door Coaster Construction Continues
The new filing comes as work progresses on the enormous show building being constructed for the Monsters, Inc. Door Vault coaster.
Recent aerial photographs have documented the installation of multiple levels of roller coaster track inside the building, along with continued work on the structure itself.
The coaster is designed around the memorable door-vault sequence from Pixar’s 2001 animated film, in which Mike and Sulley travel through an enormous storage facility filled with suspended doors.
Disney has described the attraction as its first suspended roller coaster, with ride vehicles that take inspiration from the doors moving through the film’s vast storage system.
The attraction will also feature a vertical lift, recreating another distinctive element of the movie’s climactic sequence.
Construction has progressed considerably since the first track sections appeared earlier this year.
The new permit may point toward additional themed construction, although there is not enough information to determine exactly how the work fits into the coaster’s overall schedule.
Monstropolis Is Replacing the Former Muppets Courtyard
The coaster is part of a much larger transformation underway at Disney’s Hollywood Studios.
The former Muppets Courtyard and surrounding area are being reimagined as Monstropolis, a fully themed city inspired by the world of Monsters, Inc.
The project includes both newly constructed facilities and the transformation of existing buildings.
MuppetVision 3D and nearby dining and shopping locations closed to make way for the expansion.
Disney is retaining and repurposing several existing structures while constructing the roller coaster and its associated facilities in another section of the project area.
As construction continues, the former courtyard is gradually taking on the appearance of the animated city, complete with new architectural details, themed facades, and other streetscape elements.
The coaster will serve as the expansion’s major thrill attraction, but it is only one component of the new land.
Several Monstropolis Experiences Are Opening in 2027
Disney has already confirmed that the first phase of Monstropolis will open in 2027.
That initial opening will include the Glob Theater, where Mike and Sulley will host a new show called Welcome to Monstropolis.
The entertainment experience will introduce human visitors to the city and feature an original song written by longtime Pixar composer Randy Newman.
The land will also include Archie’s Scare Pig Pizza, a quick-service restaurant inspired by the university culture seen in Monsters University.
Harryhausen’s, the restaurant featured in the original Monsters, Inc. film, will become a new table-service dining location.
Disney has confirmed that Harryhausen’s will include a sushi-chef Audio-Animatronics figure.
A themed merchandise location called Scareporium will also welcome guests as part of the first phase.
The Door Vault coaster, however, will not be ready when these initial offerings open.
Disney has confirmed that construction on the roller coaster will continue beyond the land’s 2027 debut, but it has not announced a specific opening date for the attraction.
Another Step Toward Hollywood Studios’ Next Major Expansion
For now, construction crews remain busy bringing the various pieces of Monstropolis together.
The latest permit joins a growing collection of construction filings associated with the new land, including earlier permits for scenic installation, restaurant work, and the conversion of existing entertainment spaces.
The reported set installation work is another development worth tracking as the coaster’s building and surrounding infrastructure continue to take shape.
There is no indication that the new filing changes the announced opening schedule or confirms any previously undisclosed ride features.
Nevertheless, it provides another documented step in the construction process for one of Walt Disney World’s most anticipated upcoming attractions.
With the first phase of Monstropolis scheduled for 2027 and the Door Vault coaster following later, Disney’s Hollywood Studios is preparing for a major transformation over the next several years.
