Do lenders ever call on HELOC early for full payment

[Paul Dario Jr]

Hey all. I've secured a HELOC in order to finance my backyard ADU build. Already have plans drawn and getting ready to submit for permitting. But I'm getting a bit of cold feet regarding the HELOC. Assuming I draw $100k from the HELOC, is it ever likely that the bank/credit union would call on that HELOC to be paid in full after I've drawn off of it? The only thing that's of lingering concern is whether or not the credit union can call on full payment of the HELOC balance after I've drawn on it. Is that a possibility? Wasn't sure if that's a practice of lending institutions. Thanks for the input.
