When can a landlord deduct normal wear and tear expenses without giving the tenant a 24-hour notice?

A landlord is not permitted to deduct expenses for normal wear and tear from a tenant's security deposit. Normal wear and tear accounts for the expected decline in a property’s condition due to everyday use over time, which is not the responsibility of the tenant. Thus, landlords cannot collect fees associated with general maintenance and upkeep as a result of this natural and expected use.

In terms of the context provided by the other options, they reflect misunderstandings or misapplications of landlord responsibilities around property maintenance. For instance, options discussing deductions based on costs or tenant notifications ignore the fundamental principle that wear and tear is a normal part of property usage that should not be charged to tenants. Having a prior notice from tenants or the cost being less than the security deposit doesn't change the obligation to cover normal maintenance from the landlord's perspective. Therefore, the only appropriate stance is that landlords should not deduct normal wear and tear costs from a security deposit under any circumstance. Doing so would not be justifiable or lawful.
