It will be added to my vetting procedure list I am concocting.

As well as procedures for delinquency etc.

You will want to get on the same page as far as policies and procedures. 

NEVER AGAIN, but I have learned a lot & massaging them is akin to poking a sleeping dragon.

Generally, I try and honor this sort of request, when it's reasonable....but, she is not being reasonable at all, and is requesting service that is not standard operating procedure for scheduling this sort of work.

My question is where do I go to get the information I need: Legality, zoning, procedure?

First a person must have a qualified DISABILITY, then comes the ACCOMMODATION.Establish a clear policy and procedure about making accommodations.

—When the lease is silent on the procedure to be followed to effect repair or maintenance and the payment of rent relating thereto, yet affirmatively and expressly places the obligation for same upon the landlord, and the landlord has failed or refused to do so, rendering the leased premises wholly untenantable, the tenant may withhold rent after notice to the landlord.

I would like to know the steps or procedures to buying a home.

The answer also depends if it is a request for a one time need, or ongoing need.Everything is negotiable, but if I am going to change my normal operating procedure to accommodate a tenant's need, then the rent will be higher to compensate me for this.
