No, not legally, at least.
Another View: Respectfully disagree with the above answer. The landlord ought to consider the consequences of a civil suit for slander, or libel IF THE INFORMATION GIVEN TO THE EMPLOYER IS UNTRUE. However, there is no legal prohibition barring the communication of a US citizen with any business, over any subject they may wish.
That would depend on why the landlord contacts the tenants employer and what is said between the two of them I would think. I would suggest asking an attorney about this issue however.
There are landlord and owner liability insurances available. A good lease agreement and deposit for damages can also help you cover damages by tenants.
If the tenant damages the property he is liable for such damages. The Landlord may or may not have his own insurance for this purpose but the tenant is liable. If the Tenant has his own insurance (Renter's Insurance) then the Tenant may file a claim and damages will be covered by that insurance.
The answer is basically no. The landlord is never responsible for damages to personal property belonging to tenants in any dwelling or structure. That is why you are strongly encouraged to get renters insurance. In some cases you may have some recourse if the landlord knew of the problem. But if you get renters insurance be insurance company can determine that for you and they can seek damages from the landlord.
That would depend on who's angry wife your talking about. If the tenants wife damages your property or your landlords property then the tenants wife is liable for those damages. Due to the extension of common law you can also be held financially liable for actions of your spouse. The landlord would have no control over the tenants wife nor her actions and could not be held liable. If the Landlords wife came over and damaged your property or the landlords property then the Landlord and or the landlord wife would be financially liable.
No. This is why landlords require tenants to carry renter's insurance. Call your car insurance provider.
The landlord because it's his responsibility to fix it before the house and/or property is damaged.
Yes, it is generally legal for a landlord to charge tenants for plumbing repairs if the lease agreement specifies that tenants are responsible for such repairs.
Tenants have the right to complain about other tenants that are disruptive. If the landlord fails to act, then the tenants may take their complaint to the government department that that oversees Landlord Tenant disputes. This department has the authority to compell the landlord to take action if they can't or won't do it on their own.
If this noise is a problem for other tenants, the landlord may be in violation of the lease with the other tenants. This would give them a reason to leave before their lease is up.
"The tenants agreed to ask the landlord to remove snow from the path."
Yes, a landlord can request a credit report from potential tenants as part of the rental application process.
