Can the entrance door be opened from the outside instead of from the inside?

For residential buildings, it is a common design method to open the entrance door inward, but if the entrance door opens outward, it will usually reduce the effective width of the evacuation passage and affect the use of indoor fire hydrants, so it is not recommended.

Before replacing the entrance door, you need to confirm with the property whether it can be replaced. If the entrance door is opened outside, it will not affect the neighbors' walking back and forth, and will not affect the evacuation of walkways and stair platforms, then it can be opened outside with the consent of the property.

However, if the corridor space is limited, it is not allowed to open from the inside out, because it will affect the smooth flow of the corridor outside, and it may not meet the fire code. In addition, if replacing the entrance door may endanger the safety of citizens or hinder the traffic of neighbors, it is best to communicate with the property and related departments to get more specific guidance and suggestions.

In short, before changing the entrance door, we must consider the possible impact and consequences, abide by relevant regulations, and make changes after obtaining property approval.
