Doors do not need to be shut. However, there is a bug where doors opening into minimally sized houses can cause them to be invalid because the door takes up space in the interior, causing the house to no longer meet minimum size requirements, and shutting the door can sometimes solve this issue. Opening the door to the outside can also solve the issue, as can making the house larger.
