Est. 1920 · One of San Juan's earliest surviving commercial buildings (1920) · 1940s robbery with two confirmed shooting deaths · Longtime residence of Hidalgo County Deputy Sheriff Tom Mayfield (1915) · Identified by UTRGV author Dr. David Bowles as most haunted in the Rio Grande Valley
The San Juan Hotel was constructed in 1920 and served as a hub of activity in San Juan, Texas, during the city's development period in the early twentieth century. It was one of the prominent commercial addresses in town during the years when the Rio Grande Valley was undergoing significant agricultural expansion.
The most documented violent incident in the hotel's history occurred during the 1940s when two men were shot and killed during a robbery on the premises. Both deaths are confirmed in regional historical sources, and the incident has remained the primary historical anchor of the building's dark-tourism reputation.
Among the hotel's notable former residents was Tom Mayfield, who served as a Hidalgo County deputy sheriff in 1915. Mayfield reportedly lived at the hotel for an extended period. UTRGV author and Rio Grande Valley folklorist Dr. David Bowles has identified the San Juan Hotel as the most haunted building in the entire Rio Grande Valley, based on the density and variety of reported phenomena associated with it.
Sources
Paranormal accounts at the San Juan Hotel center on two recurring presences. The more frequently reported is an apparition on the second-floor balcony, associated in local lore with a woman who died at the hotel during its operating years. Witnesses describe the figure appearing on the balcony and receding when approached.
A second presence is associated with Tom Mayfield, the former Hidalgo County deputy sheriff who lived at the hotel for an extended period in the early twentieth century. Accounts describe this presence as protective rather than threatening — a watchful figure rather than an aggressive one. Mayfield's documented 1915 service as a deputy gives his name a verifiable anchor in the historical record.
Dr. David Bowles, a published author affiliated with the University of Texas Rio Grande Valley who has written extensively about South Texas folklore and paranormal history, has publicly identified the San Juan Hotel as the most haunted building in the entire Rio Grande Valley. His designation is based on the variety and persistence of phenomena reported at the site over several decades.

Every HauntBound history is researched from documented sources. We clearly separate verified historical fact from paranormal folklore.
Bakersfield, CA
Built in 1928 as Bakersfield's tallest building, the eight-story Spanish Colonial Revival Padre Hotel stood at the center of downtown commercial life for decades. A fire damaged the seventh floor in the 1950s during the 45-year ownership of Milton Miller (1954–1999). The hotel closed for eleven years before reopening in 2010 after a full renovation, and now actively markets the seventh floor's haunted reputation.
Lubbock, TX
The Pioneer Hotel at 1200 Broadway Street was constructed during the 1920s as a premier eleven-story lodging establishment during Lubbock's economic boom period. The building served as the city's flagship hotel for decades. Following periods of decline and extensive renovation, the structure now houses the Pioneer Pocket Hotel and mixed-use retail spaces, preserving its distinctive renaissance revival architecture.
San Antonio, TX
The Gibbs Building was erected in 1909 as San Antonio's first office skyscraper, built on the northwest corner of the original Alamo compound. During excavation that year, workers uncovered five Alamo-era cannons in the basement. The building was converted to a hotel in 2006.
