The exterior walls of small buildings are often easily accessible and the GBA is considered to be the same as the net rentable area for analysis purposes. Some appraisers use decimal measurements so 20.4’ is 20 and 4/10 feet. Others use feet and inches so the measurement may be 20 feet 5 inches or 20’ 5”. You have to pay attention to what is presented by an appraiser in a sketch or drawing to see what convention he or she is using.Measurement
