Lenders that appraise ADUs accurately so I can increase my HELOC?

[J Kilroy]

Does anyone have a recommendation for a lender that values ADU's in CA "accurately"?

We completed our ADU earlier this year at our primary residence and it has been a great cash flowing investment. We used a HELOC from First Bank and they were great to work with in getting us a HELOC at a great rate. We would now like to increase our access to cash via a HELOC that incorporates the new ADU in the appraisal. In talking to First Bank they are not able to tell me if the ADU will add value to our home when being appraised so I am looking at other lenders.
