    Some people here (not me) think that screens are required if you are using doors for natural ventilation.

    Not totally Correct, in California

    CA Building Code 1203.5 Natural Ventilation
    Natural ventilation of an occupied space shall be through windows, doors, louvers or other openings to the outdoors. The operating mechanism for such openings shall be provided with ready access so that the openings are readily controllable by the building occupants.
    [HCD 1] In employee housing, all openable windows in rooms used for living, dining, cooking or sleeping purposes, and toilet and bath buildings, shall be provided and maintained with insect screening.
    [HCD 1] Door openings of rooms used for dining, cooking, toilet and bathing facilities in employee housing shall be provided and maintained with insect screening or with solid doors equipped with self-closing devices in lieu thereof, when approved by the enforcement agency.

    Under OSHPD
    1224.4.9.4 Screens
    Windows which may be frequently left in an open position shall be provided with insect screens of 16 meshes to the inch.

    Virginia has a similar requirement for screens on windows or doors used for natural ventilation.

    Interesting. What is the definition of employee housing? Must be a CA thing, not in the IBC.

    The Employee Housing Act and the adopted regulations govern the standards for the construction, maintenance, use, and occupancy of living quarters, called "employee housing," provided for five or more employees under specified circumstances. Employee housing subject to the Act is privately-operated and does not include government-owned or -operated migrant worker facilities.
    In general, employee housing is privately-owned housing that houses five or more employees and meets the following:
    • Living quarters provided in connection with any work, whether or not rent is involved.
    • Housing in a rural area that is:
      • Provided by someone who is not an agricultural employer, and
      • Provided for agricultural workers employed by any agricultural employer.
    Any city, county, or city and county may assume responsibility for enforcement of the Employee Housing Act upon written notice to, and approval by the Department. Where a local government has not assumed enforcement responsibility, or enforcement has been taken away from a local agency because of non-enforcement, the Department is the enforcement agency.

    Agriculture is a significant sector in California's economy, producing nearly $50 billion in revenue in 2018. There are more than 400 commodity crops grown across California, including a significant portion of all fruits and nuts for the United States. In 2017, there were 77,100 unique farms and ranches in the state, operating across 25.3 million acres of land. The average farm size was 328 acres, significantly less than the average farm size in the U.S. of 444 acres.

    Much of the vegetables you eat, come from CA. That is why it is so stupid to stop the migrant workers from coming across the boarder. All the wall people are doing is costing themselves more at the market.
