Will an appraiser deduct value for non-permitted work?

[Noah Hoffman]

I want to refinance my duplex within the next 6-12 months but I’m wondering if the appraiser will have a problem with non-permitted work done in the garage. I know the non-permitted work won’t count towards added value but will it take away or will it jeopardize the refi? I think many oeople have had dIfferent experience wIth this Thanks
