    I was able to locate the code from 2015 that does talk about specs of a rain cap: http://www.seattle.gov/documen...

    After digging I found the code, apparently it is required: 

    R1003.9.1 Chimney Caps

    Masonry chimneys shall have a concrete, metal or stone cap, a drip edge and a caulked bond break around any flue liners in accordance with ASTM C 1283. The concrete, metal or stone cap shall be sloped to shed water.
