I started my own office services business in my condo in 2016. My condo is paid for, but I still pay association dues.

I cannot take the home office deduction becasue I use the space to also pay my own bills, and eat.  But can I take a portion of the association dues and the electric bill?  Or is that included in the home office deduction?  My apologies for my ignorance but this is all new to me.
