Indoor rehearsal spaces for ensemble band

Hey everyone, I'm with a local school organization and we are planning a variety show that raises money for charity (broadcast online this year). I work with the band, and we are struggling trying to find indoor spaces for rehearsal. The school where we usually rehearse has denied us due to Covid safety, however I was wondering if there were any old warehouses or unused spaces that could potentially host our rehearsals.

Any recommendations are welcome! :-)
