My question involves landlord-tenant law in the State of: California

I will be moving out of my current apartment at end of Sept. (2016). I have lived in this unit for 22+ years.

I have a landlord who has notoriously hit tenants for excessive charges on move-out. Having been landlord myself many years ago, I understand the landlord's perspective of getting paid for damages. So I understand my responsibilities as a tenant to pay for damages.

What I am trying to understand in advance of moving out in terms of my tenant rights -- since I have lived here for 22 years, can the landlord charge me for repairs for any items that are well beyond their normal life span?

For example,

My kitchen countertops are made of some form of laminated particle board. In the area closest to the sink that gets exposed to lots of moisture and where I wash dishes, there are areas where the finish/top layer has worn through. My concern is that my landlord will still attempt to come after me for that and call it damages.

has does one discern what is "normal wear and tear" vs. true damages in this situation? Even if falls under the heading of damages, does not the landlord need to depreciate it, taken into account the life span of laminate countertops?

On a similar note, there are some wear spots in terms of tub finish (2 spots about size of quarter). I know I never dropped anything in the tub or done anything (beyond normal cleaning with products safe for tubs) to the finish being worn through. Again considering I have been in this place 22 years, is that considered damage or normal wear tear?

FYI, except for emergency repairs -- like stove caught on fire, my landlord has not maintained my unit in any way since I have been here for 22 years. Even including things like caulking, or replacing toilet seat.

Would love to understand my rights vs landlord rights in this situation. Thanks.
