Recently while writing a story set in 1968 inside a fictional, historical hotel, modeled on the Driskill Hotel in Austin, Texas, I ran into a question about hotel doors. Finding the answer took me down a rabbit hole of research into the safety codes and regulations governing hotel doors and locks.
In the 1800s many hotels kept room keys on hooks behind the registration desk. A guest would be given the key when they checked in. When leaving the hotel temporarily, guests would leave the bulky, skeleton-style keys at the desk and reclaim them when they returned. Desk clerks would know at a glance if a guest was in the hotel at any given moment.
With improvements in locks and the manufacturing of smaller keys, guests began to keep room keys in their possession when leaving the hotel temporarily. Housekeepers and managers had to have master keys to be able to access rooms when guests were out or lost their key. Hotel doors in the early 1900s did not close and lock themselves. For my story I needed to know at what point the regulations changed to require hotel doors to close and lock themselves.
This turned out to be two different questions because the requirement for self-closing is separate from the issue of self-locking.
On the issue of self-closing doors, I learned that hotel fires spurred building code changes. The June 5, 1946, La Salle Hotel Fire in Chicago killed sixty-one people. The Canfield Hotel Fire in Dubuque, Iowa, on June 9, 1946, killed nineteen people. And the Winecoff Hotel Fire on December 7, 1946, in Atlanta killed one hundred nineteen people. On the heels of these 1946 fires, building codes across the United States were changed in the 1950s to require self-closing, fire-resistant doors in hotels, and enclosed stairwells to protect people escaping from fire. The regulations only required the doors to self-close, not to lock.
Additionally, in many places, older buildings were not required to meet newer safety codes. After the 1970 Ponet Square Fire, Los Angeles passed regulations requiring retrofitting older buildings over two stories tall with enclosed stairwells to provide a protected path out of the building. The Ponet Fire Door ordinance required the installation of self-closing doors that could block the spread of fire for at least one hour on rooms and stairwells. But different states and localities have different rules on retrofitting of older buildings. After the 1980 MGM Grand Fire in Los Vegas, a commission was formed in Nevada to discuss the need for making older buildings comply with newer regulations.
I still didn’t have an answer on the question on whether the door self-locked. Here Mr. John Payne, a forensic locksmith, came to my rescue. He said: “The lock side of the equation was solved earlier: Walter Schlage patented the “key shutout mechanism” — the core of what we now call the “hotel lock function” — in a series of patents beginning in 1933. The typical hotel function lock had an outside handle that did not move and a key was required to retract the latch to enter from the corridor. The door would automatically latch behind every guest who entered or departed the guest room. The combination of a self-closing door and a self-latching hotel lock cylinder meant that by the mid-20th century, a hotel guest needed to do nothing at all when leaving a room — the door closed, latched, and locked itself.” Thus, hotels built after the mid-1930s would probably have these newer door locks.
But Mr. Payne pointed out, many hotels didn’t consider functional door locks for guest security to be an important responsibility until after singer Connie Francis sued Howard Johnson Hotels in 1976. Ms. Francis was beaten and raped in her hotel room. Her attacker gained entrance through a sliding glass door that was easily opened from the outside. The hotel was aware that the door locks were not sufficient and that other incidents had occurred at the hotel. A jury found the hotel liable for the assault. Prior to this lawsuit, only the assailant had ever been held responsible for such an attack in a hotel. This lawsuit (Garzilli vs. Howard Johnson Motor Lodges, Inc.) was the first to establish that hotels are required to provide adequate security for guests, which includes functional door locks.
After this deep dive down the research rabbit hole, I had the answers I needed to make my story work. My fictional historical hotel built in 1886 might not yet have self-closing, self-locking doors in 1968, especially if it was scheduled to undergo a major renovation in 1969 to bring it up to code. My fictional hotel guests would still have to manually close and lock their own hotel room doors using the original Victorian era knobs and locks. Which means, someone might forget to lock a room, allowing for a robbery to occur. Thus, the crime in my story was plausible. Now, I won’t have people writing to tell me that the fictional thefts in my fictional hotel were impossible, and more importantly, the editor who questioned the door closing and locking situation and sent me down this research rabbit hole is satisfied.
Finally, I have a new story out in Black Cat Weekly #242. “The Case of the Dead Man’s Daughter” features genetic genealogy private detective Maya Laster. I’m thrilled for her story to be featured on the cover of the magazine.
