Heated area is the County figure, not an independent measurement. The County displays 4,724 sq ft of Heated Area, 2,462 sq ft of Live Area and 2,262 sq ft of Finished Basement Area. Main floor 1,817.0 plus finished upper story 645.0 equals 2,462 sq ft exactly; adding the detailed finished-basement figure of 2,261.7 gives 4,723.7 sq ft. The reviewed records do not explain the 0.3-sq-ft detailed/display differences; no rounding method is assumed. The separate Basement Area field is 0, while the card also records the finished basement and describes GARDEN LEVEL / FBM. Garage and deck areas are reported separately. The sketch also labels a hatched region “NCA 250.0”; its meaning is not defined in the reviewed records, and it is not added to the living, heated or basement figures.

Notes
The County building card records 5 bedrooms, 6.5 bathrooms and 4,724 square feet of heated area. This profile follows account R060498 and situs 3877 Lupine Drive #E. The account-linked sketch is labeled “Unit #B”; the reviewed records do not explain that label’s relationship to #E or verify an entrance. The County records one unit, and the 2026 notice limits its characteristics to the first building. These are linked County account and building-record figures, not an independent determination of dwelling allocation or exclusive property areas. Current condition, configuration and alterations should be confirmed through a property visit and current documents.
