What is the minimum distance smoke alarms must be installed from the door or opening of a bathroom?

The minimum distance that smoke alarms must be installed from the door or opening of a bathroom is 3 feet. This requirement is established to reduce the likelihood of false alarms caused by steam or humidity generated during showers or baths. If smoke alarms are installed too close to a bathroom, the moisture can trigger the alarm, leading to unnecessary disturbances and potentially desensitizing occupants to alarms in genuine emergencies. Therefore, maintaining a distance of at least 3 feet ensures better performance and reliability of the smoke alarms while providing adequate protection against fire hazards in living spaces.
