Generally, if the tenant or a guest of the tenant damages the premises or inclusions (either maliciously, intentionally, or accidentally) they would have to pay for any damage caused.
If there is an unnecessary delay in notification and the damage is then beyond repair or will cost more because of the delay, the tenant may be liable for costs.
The tenant may be asked to compensate the property manager/owner for the cost of repairing the damage if the repairs are carried out by the lessor.
Example: The tenant has accidentally broken a window while playing basketball outside. The tenant notifies the property owner/manager they have accidentally broken the window. However, the tenant cannot currently afford to make the repairs.
As the managing party of the property, the property manager/owner has an obligation to ensure the premises is reasonably secure. They repair the window at their cost and enter into a payment plan with the tenant to recover the cost for the repairs.
