Landlord renovating tenant's bathroom without providing temporary

[Neil G.]

friend with wife and young daughter mentioned their landlord is knocking down shower and bathroom walls, and they just had to shower and use the bathroom in backyar. said landlord refused to provide even a local motel room to go and use the bathroom/shower at.

friend seems irate enough to be especially upset that has 2 yr lease and 'feels' landlord/owner's actions are in breach of it. also mentioned in ripping out walls they and some framing are covered in 'black slimy looking stuff' and the repairmen did not cover any of his furniture and it may be contaminated (with dust, debris, spores?)

offered mine as temporary relief but wonder what their rights are? they are in long beach, ca.. part of los angeles county.
