The setbacks you noted are similar to those in NY.  There are exceptions to the setbacks based upon alternative access to the roof.  These are amendments to the NY Building Code, which amended the IBC/IFC regarding this aspect of solar installations.  Email me off list if you would like slides from a PPT presentation we created on this topic.  Chris

    Hey Gary,

    Ohio Fire Code does cover this. It’s a matter of if the Fire
    marshal in you project area wants to waive or alter the requirements.

    http://codes.ohio.gov/oac/1301:7-7-06v1

    Specifically 605.11.1.2 is for residential buildings. There is
    some conflict in terms of Hip roofs in the code there.
    605.11.1.2.2 states a single 3ft path on one edge or another for a
    hip roof, but 605.11.1.2.4 states that an 18 space is allowed when
    modules are mounted on two adjacent roof planes with a hip roof.

    With Regards,

    Daniel Young,

    Hello Wrenches,

    What are you all seeing required as setbacks post 2017?  I am
    having inspectors vary between wanting a 3' lane at the bottom and
    sides to allowing the array down to the gutter, and from requiring
    between 18" and 3' at the ridge.
