We are in a fire sprinkler retrofit and we have steel joists and decking throughout the building, with mostly masonry block walls. It's a single-story structure.
Where there are doors, however, there is wood framing above the grid ceiling. How much wood constitutes an issue requiring fire sprinklers above the ceiling? Posted anonymously for discussion. Discuss This | Submit Your Question | Subscribe

The combustible materials cannot be acting as structural elements (floors, ceilings, walls, load bearing...).

Chapter 9.2.1 Concealed spaces not requiring sprinkler protection (Ed. 2019) will give you some guidance.
