    If the separation wall between the house and garage puts the duct in the garage, then the duct is wrong. If the heater is "in the house" on the house side of the separation wall between the house and garage, then it would be OK.
    From what I see around here, it would be wrong since the W/H closet door would not be an approved door between the house and garage, thus the separation wall would be the back wall of the W/H closet. That would also mean the OSB would violate the separation requirement of 1/2" gypsum, assuming you are on the IRC.

    Clay,

    First this needs to be answered: What kind of door is it? All the door needs to be is solid core 1-3/8", i.e., just a regular old cheap 1-3/8" solid core door.

    R309.1 Opening protection.
    Openings from a private garage directly into a room used for sleeping purposes shall not be permitted. Other openings between the garage and residence shall be equipped with solid wood doors not less than 13/8 inches (35 mm) in thickness, solid or honeycomb core steel doors not less than 13/8 inches (35 mm) thick, or 20-minute fire-rated doors.

    What Jerry said.
    The entire section of R309 deals with garages and carports.
    The main theory here is "309.2 Separation required. The garage shall be separated from the residence and its attic area..." and then goes on into specifics.
    In general, the common walls and ceiling have to have gypsum board on the garage side and proper doors on any openings through the separation wall.

    To continue what Jim said ...

    *IF* the door is one of the correct type doors, then the OSB ceiling is not a problem and neither is the duct.

    *IF NOT* (if the door is not a correct type door), then *both* are problems.

    Must be a lot of Hollow core doors in Texas . I pictured some (magical) special door based on combination of what wall is who? Appendix # ****

    Clay the door is the key as everbody says but if it is a solid door, looks like there may be some combustion air issues.

    To expand on Buddy's "solid door" (not "solid core" door) statement above ...

    *Even if* it is a "louvered door" (versus a "solid door") there are likely combustion issues.

    In thinking about "the door" I 'thought right over' the combustion air issue (meaning I forgot about it ).
