When installing an interior door leading to the garage, it is important to ensure that the door is fire-rated and equipped with a self-closing mechanism. Additionally, a weather seal should be installed to prevent carbon monoxide from entering the house. It is also recommended to have a smoke detector installed near the door for added safety.
