Fire in 4-plex; what's landlords obligation?

[Shane S.]

I'm in the process of purchasing a 4-plex that had a fire in one of the units; the structure is fine but it got me thinking. If a fire happens in a multi unit property and forces all the tenants to move, what is the landlord required to do? Does the owner have to pay to relocate all the tenants? Does insurance have to? Or is it up to the tenants?

I tried to find information on this but didn't have any luck. If you have any input or know of any articles it would be much appreciated.
