Can Board lien property for loan

Can a Board (I'm in California) obtain a loan on behalf of the Association
and pledge our property, via a lien as collateral, without a vote of
Homeowners?

Can they do this by majority vote or do they have to get each Homeowner to
agree to this?

Are there any laws that refer to this situation?

I know that they can place a lien on a property if someone doesn't pay an
assessment but in this case they would be using the lien as collateral to
borrow money which would THEN become an assessment.

Anyone have any ideas on this?
