Student renters questions

[Jem J.]

I have several students interested to rent. Their questions are:

1" In regards to prohibited flammable materials, propane grill is ok ? What about household chemicals which are considered toxic or flammable , will these be considered a breach of lease?

2. Do they each need a renter's policy or can they get a renters policy as a group?

Any thoughts Landlords? 

Thanks.
