I have a CA rental property generating loss, do I need to file CA tax return?

I have a rental property in CA, it's generating paper loss. 

I don't have any other income from CA.

I didn't step into CA for the whole year.

I have filed my federal return and it's accepted.

The CA state tax return will be $0 since no income and no withhold. 

 

Must I file CA tax return?

My income exceeds the limit to use CalFile so I have to pay for other software to E-file, which doesn't make sense to file a 0 with extra cost.
