California - Turning Space Conflict

On a commercial project in California looking at an individual restroom. Section 11B-603.2.1 requires a turning space complying with 11B-304 be provided within the room. 11B-603.2.3 limits the door swing encroaching into the turning space. The two are only allowed to overlap by 12". However, 11B-304.4 states that doors are permitted to swing into turning spaces. So which one is it? Only a 12" overlap is allowed? Or is more than a 12" overlap allowed?
 
Refer to CBC Section 1.1.7.2. The provision in Section 11B-304.4 is a general provision. The provision in Section 11B-603.2.3 is a specific provision (applies only to toilet and bathing rooms).

Thus, Section 11B-603.2.3 takes precedence, and you must comply with it, not Section 11B-304.4.
 
I don't see a conflict.

11B-603.1 General
Toilet and bathing rooms shall comply with Section 11B-603.
11B-603.2 Clearances
Clearances shall comply with Section 11B-603.2.
11B-603.2.1 Turning Space
Turning space complying with Section 11B-304 shall be provided within the room.
11B-603.2.2 Overlap
Required clear floor spaces, clearance at fixtures and turning space shall be permitted to overlap.
11B-603.2.3 Door Swing
Doors shall not swing into the clear floor space or clearance required for any fixture. Doors to accessible water closet compartments shall be permitted to encroach into the turning space without limitation. Other than doors to accessible water closet compartments, a door, in any position, shall be permitted to encroach into the turning space by 12 inches (305 mm) maximum.
Exceptions:
Reserved.
Where the toilet room or bathing room is for individual use and a clear floor space complying with Section 11B-305.3 is provided within the room beyond the arc of the door swing, doors shall be permitted to swing into the clear floor space or clearance required for any fixture.
In residential dwelling units complying with Section 11B-233.3.1.1, doors shall be permitted to swing over the turning space without limitation.

11B-304.3 Size
Turning space shall comply with Section 11B-304.3.1 or 11B-304.3.2.
11B-304.3.1 Circular Space
The turning space shall be a space of 60 inches (1524 mm) diameter minimum. The space shall be permitted to include knee and toe clearance complying with Section 11B-306.
11B-304.3.2 T-Shaped Space
The turning space shall be a T-shaped space within a 60 inch (1524 mm) square minimum with arms and base 36 inches (914 mm) wide minimum. Each arm of the T shall be clear of obstructions 12 inches (305 mm) minimum in each direction and the base shall be clear of obstructions 24 inches (610 mm) minimum. The space shall be permitted to include knee and toe clearance complying with Section 11B-306 only at the end of either the base or one arm.
 
Are we supposed to read 11B-603.2.3 with a comma in it, such that the term "clear floor space" refers to the floor surface of the turning space (11B-304.2)?

"Clear floor space" is a prescribed element per CBC Section 11B-305.3 (as mentioned by the reference in that exception), which is not the "turning space" prescribed by CBC Section 11B-304.
