I would say yes you need a seismic joint, the building and the pergola move independently in the events of a seismic event which could very easily shear the pipe.

A 1" fire sprinkler line comes out of building to supply fire sprinklers under the pergola. Would a seismic joint or flexible couplings be required? Owen Evans
