Also you would ideally get permission from the neighbor in writing first to avoid myriad issues.

your contract with them should require permission from you, unless it is an emergency, for repairs over a certain about. 

The owner should be able to show up whenever they want to occupy the cottage, without advanced notice or permission.

@Robin Evans  ah pets,  you probably can't determine if the other landlord gave her permission  but that lease is up and you said she is on month to month now,  you gave her a fee and she won't pay it. 

I would then schedule an inspection within one week to see how well they're caring for the property.The violation is that he added people without your permission.

However, some property management companies want a form to fill out and they want something in writing from the Applicant that gives them permission to share.

Without permissions, you do not have access to the property to enjoy any of the improvements you've made.

This speaks to the 2 path's of human actions and which you fall into, if your a "ask for permission" person or a "ask for forgiveness" person.

If the manager did this without your permission, then the responsibility for those costs are his.

Since this is an ongoing issue I started asking them if they give permission to enter the property to make the necessary repair and I'll use my key and they even agreed to that for todays repair but then we went there today to make the necessary repairs and we have an inspection coming up in three days and these repairs need to be completedand they had the doors  locked from the inside with some type of security bolt so we couldn't  enter even with our key how would you guys proceed to resolve this in the future do you think I should put some type of clause in my lease where it states if the tenant is not there at the scheduled appointment time they pay a certain fee for a missed appointment but going forward I don't know if they're going to want to sign this document and they are Section 8 tenants but I have to check with housing authority as well on that. any advice I would greatly appreciate it thank you so much you guys helped me so much
