Does a legal ADU or a finished basement add to my home's value?

A legal, permitted ADU generally adds more value than a finished basement across the Lowcountry, since basements are rare here to begin with while an ADU creates genuine additional living or rental space a lender can recognize on an appraisal. Permitting status decides whether either feature helps or hurts a sale. Brian Beatty checks permit records and comparable sales before crediting either improvement in a valuation.
