This year's February issue of Futabasha's Monthly Action magazine announced on Tuesday that Coolkyoushinja's Miss Kobayashi's Dragon Maid manga is getting a third spinoff series beginning in the next issue on January 25. The "slightly lewd" comedy is titled Kobayashi-san-chi no Maid Dragon: Lucoa wa Boku no xx Desu. (Miss Kobayashi's Dragon Maid: Lucoa is my xx), and it focuses on Lucoa and Shota. Utamaro (Maji Bura!?) is drawing the manga.

Around a year before Seven Seas Entertainment they announced that the Kobayashi-san Chi no Maid Dragon: Kanna no Nichijou manga will getting a English release, they have now announced on twitter that they will be publishing Kobayashi-san Chi no Maid Dragon: Elma OL Nikki in English.
Since it was just announced there is obviously no date currently set for the first volume to be released. Though going by the same time frame for Kanna's side story it could possibly be around 6-7 months before it comes out.
Elma's Office Lady Diary currently has only 1 volume set published and around 11-12 current chapters out (not 100% so don't quote me).
