Defining Tenant Responsibility- minor problems with property

[Ryan Y.]

I can use some advice on this one... I took over an existing tenant who frequently asks for repairs, or has complaints about the property. The property is a nice, well maintained property in a nice part of town. Some of his requests include asking to spray his exterior wood pile for spiders, replace a dryer knob, replace working doorbell, and increase flow of refrigerator water line. What are the responsibilities of the landlord versus the tenant? Where is the line drawn between keeping your tenant happy and requiring them to fix some of their own problems? Thank you for your responses.
