General non-responsiveness from tenants in adhering to agreement

[Katharina Bormann]

Hello,

How do you handle non-responsiveness from tenants regarding not-so-critical issues. E.g.,
1. If the tenant does not clean up large trash items in the backyard despite repeated requests. The contract says - RESIDENT shall be responsible for disposing of items of such size and nature as are not normally acceptable by the garbage hauler.
2. If the tenant is dilly-dallying in paying the repair costs for (not wear-and-tear) damage for more than 1 week. The contract says - RESIDENT agrees to keep the premises and all items in good order and good condition and to immediately pay for costs to repair and/or replace any portion of the above damaged by RESIDENT.

3. If the tenant does not keep the basement clean to an extent that it might be attract mice.

The contract does not have any explicit language stating "Failure to do so will results in penalties or such and such...".
I dislike sending multiple reminders. What is the recommended way of handling this?

Thanks
