Secret Annex security rules

The Secret Annex security rules were the practical, continually revised measures by which the people hiding in Otto Frank’s office building tried to prevent discovery. From the original limits imposed by anti-Jewish decrees to the stricter procedures adopted after burglaries exposed weaknesses in the building, the rules governed movement, water use, windows, noise, and even where residents could work. They offered no real security from persecution; they organized daily life around the risk of being found.

Origins and the Hidden Address

The need for concealment grew out of a system that had already stripped Jews of ordinary freedoms. After the German occupation in May 1940, decrees required Jews to wear the yellow star, restricted shopping to specified hours, and prohibited streetcars, private cars, evening outings, entertainment, sports, and visits to Christians’ homes. The rules of hiding were therefore layered over state-imposed restrictions: a family already marked and constrained had to regulate itself more closely still to stay alive.

The Frank family had planned to enter hiding on July 16, but Margot’s call-up notice from the SS brought the move forward by ten days. Their refuge was in Otto Frank’s office building, where employees Mr. Kugler, Mr. Kleiman, Miep, and Bep Voskuijl knew they were coming, while the warehouse workers were not informed. That distinction made discretion a structural necessity: ordinary work continued below the concealed living quarters, and any careless sound, movement, or sign of use could expose the people above.

The written prospectus prepared for the Annex turned this precarious situation into dark comedy. It advertised accommodation for Jews and other dispossessed people in the heart of Amsterdam, claimed it could be reached by streetcar or bicycle but noted that those forbidden such transport could come on foot, and listed the price as free and the diet as low-fat. The joke depended on the gap between a cheerful lodging notice and the actual rules of confinement. What the mock guide presented as a quirky establishment was, in practice, a hiding place whose occupants had to remain almost invisible.

Routine as Concealment

In the Annex, ordinary household actions had security consequences. After one burglary, residents were ordered not to wash or run water, to keep quiet, be dressed by eight, and not use the bathroom. When Peter went down to the warehouse at seven and found both the warehouse and street doors open, he alerted Otto Frank; Otto went to the private office, tuned the radio to a German station, and locked the door before they returned upstairs. The residents had not heard the break-in while asleep, but the discovery immediately changed the morning into a test of silence and compliance.

The thieves had forced the outside and warehouse doors with a crowbar. They took two cashboxes containing 40 guilders, blank checkbooks, and, most damaging to the hidden household, coupons for 330 pounds of sugar. The loss joined the threat of discovery to the everyday problem of obtaining food: security procedures could keep the occupants quiet, but could not prevent an intrusion from disrupting the supplies on which they depended.

Even waste had to be managed covertly. Because the warehouse employees might notice rubbish in the bins, vegetable peelings and garbage had to be burned, despite the heat. A small act of carelessness could endanger everyone. The same logic governed water and sanitation: a sound that would be unremarkable in a normal home might alert people working downstairs that the building was being used in ways the concealed residents could not explain.

The Rules Tighten

After a later security incident, the household imposed more extensive restrictions. Fritz Pfeffer had to do his work in the bathroom, while Peter patrolled the house between eight-thirty and nine-thirty. Peter was no longer allowed to open his window after someone from the Keg Company had noticed it standing open. The toilet could not be flushed after nine-thirty at night, and Mr. Sleegers was hired as a night watchman. A carpenter from the underground was expected to construct a barricade from the residents’ white Frankfurt bedsteads.

These measures were not settled by decree from a single authority. The occupants debated what to do, while Otto Frank reproached them for carelessness and Jan Gies warned that they should never go downstairs. They still had to assess whether the new night watchman could be trusted, whether dogs would bark if someone came behind the door, and how the barricade should be made. Security depended on judgments under uncertainty: each precaution answered a specific vulnerability, but each also raised new questions about how the building and the people around it could be trusted.

By late April 1944, the arrangements had become more precise and more burdensome. Fritz Pfeffer had not spoken to Hermann van Pels for ten days, following a quarrel over the restrictions introduced after the break-in. He was no longer allowed downstairs in the evenings; Peter and Hermann made the final round at nine-thirty, after which no one could go down. The toilet could not be flushed after eight at night or after eight in the morning. Windows could be opened only in the morning, when the lights came on in Mr. Kugler’s office, and could no longer be propped open at night. The loss of fresh air particularly angered Pfeffer, who insisted he would rather live without food than without air. The measures intended to protect the group thus became a source of friction within it.

Fear, Discipline, and the Cost of Safety

The rules belonged to a larger atmosphere of coercion, not to a danger the residents could control. The account of hostages taken after sabotage describes innocent people being imprisoned and executed when the Gestapo could not find the saboteur; their deaths were reported as “fatal accidents.” Meanwhile, Dutch students who refused to sign a declaration supporting the Germans and the New Order risked being sent to a German labor camp. Such threats help explain why the hidden residents treated an open door, a visible window, or a flush after curfew as more than a household lapse: discovery took place within a regime that used punishment and forced labor to terrorize civilians.

The narrator describes the inhabitants as Jews “in chains, chained to one spot, without any rights, but with a thousand obligations.” The line captures the paradox of the security rules. They were necessary practices devised by people with little control over their circumstances, but they also demanded constant self-restraint from those already deprived of basic rights. Their hope that the war would end and that they would again be people, not only Jews, coexists with an immediate routine measured in patrols, closed windows, quiet hours, and withheld water.

The rules could reduce risks but never remove them. Their history in the diary is a record of adaptation: a hidden address, a cautious routine, emergency orders after a break-in, and stricter controls when vulnerabilities became visible. As the precautions accumulate, the Annex appears less like a protected household than a shared space in which even sleep, air, sanitation, and companionship are shaped by the danger outside its walls.
