Does the bedroom require a door according to the building code?

[Chakri Dew]

Hello BP fellows - Any requirements for a bedroom to have a door? I'm converting a basement into a unit and trying to understand the building code for having a door? I'd like not to have a door and keep a simple opening for a reason (Tight space). I researched, and none of the articles said door as a requirement. (Of course, we will build an egress window and closet.)

We already pulled a permit with a door; I'm leaning to change it and have a straightforward entry without a door. Any thoughts?

The property is in Northern California.
