The Las Vegas Planning Commission recommended approval of a site development plan review for an expansion of The Mob Museum during its Aug. 11 meeting.
The Mob Museum is the owner and developer. LGA Architecture is the architect and representative. Chattel, Inc. is serving as a historical consultant.
The Mob Museum is located at 300 E. Stewart Ave. in Las Vegas. The expansion includes a parking lot, which is located at 350 E. Stewart Ave.
The addition is composed of a 19.5KSF building that will contain a gallery, theater, kitchen and back-of-house area. Other improvements are planned alongside the new building. The primary building will be renovated “to help improve the ticketing experience and visitor flow.”
The parking lot will be expanded and reconfigured to better fit the new capacity and space. An office trailer will also be relocated. The parking lot sits toward the eastern portion of the site, adjacent to 4th Street. The office trailer will be moved to the rear of the site.
The new building will be two stories, matching the current height of the existing building. The current museum is 35.8KSF, bringing its total new size to 55.2KSF.
According to the staff report, “The proposed addition exterior is primarily constructed of EIFS (Exterior Insulated Finish System), architectural CMU (Concrete Masonry Unit), and secondarily constructed of spandrel glass. There is a large perforated metal façade panel on the southern building elevation, the primary frontage.“
The site is zoned Civic and Commercial General, with a planned land use designation for Public Facilities and Mixed-Use. It is surrounded by land zoned C-2. The north and west feature a vacant transit passenger facility; the south has a hotel/casino, and the east contains an office.
The Mob Museum History
The building was originally a United States Post Office and Court House that was constructed in 1933. It was later made part of the National Register of Historic Places in 1983. The City of Las Vegas became the owner of the building in 2002, after it was transferred due to being deemed “surplus” by the federal government.
The building was then extensively renovated from 2002 to 2010 to become The Mob Museum. It officially opened to the public in 2012.
Since its completion, it has continued to garner more support and attention. The limited space provided by the original building has led to overcrowding during peak visitation hours. The expansion is intended to meet current and future demand.
The plan was first introduced to the Las Vegas Historic Preservation Commission in December 2025. It was later updated in April.
