Can I depreciate primary residence

[Yashar Fred]

Hi 

I understand I can calculate depreciation (standard vs itemized) and deduct from my rental property.

Can I deduct depriciation of my primary residence too ?

How about if I have a duplex and only one unit was rented out and the other was only on market with no tenants occupying it

Primary Residence - No

The side of the duplex being rented - Yes

I believe the other side that isn't rented can be depreciated as well if it's being marketed and the property is in liveable condition (e.g. someone can move in: floors down, plumbing in place, etc.)
