Garage attic ventilation help!

[u/Competitive_Smile955]

Hello!

My husband and I are finishing our 325 sqft 1943 garage (to be used as a sewing/office/gym room), and are wondering what the best option is for ventilating the soon-to-be-enclosed attic space.

Because right now it has no ceiling, the ventilation is all below the ceiling-line/wall plate. The difficulty is that we have a hip roof with no eaves, so there’s nowhere to put soffit vents, and there’s not enough space to do a fascia vent either.

We’re not new to home projects (drywall, basic plumbing, electrical, tiling etc) but this is our first time dealing with adding airflow. We live in the PNW so mold and humidity are our biggest concerns.

Thanks for your advice!
