Does an income unit add to what my Dewees Island house appraises for?

A legal accessory income unit can add appraised value on Dewees Island, but only when it is properly permitted with the county and supported by comparable sales that include similar units. An appraiser weighs it through the income approach alongside standard comparables, not as a flat add-on. Brian can tell you whether Dewees Island comparables actually support extra value for your specific unit before you spend money finishing it out.
