Room Rental and Deprication

I rent a small room out to my adult son who is on SSI. I have been taking the prorated sq/ft depreciation deduction for his room. What I want to know is can I stop taking the depreciation deduction?  I know everyone will say I should take the deduction because I will have to pay the recapture tax that I was entitled regardless if I took it or not.  I am just curious in what I have to do vs. what I should do.

Thanks
