Both basement fields are zero and the County records NO BASEMENT. The sketch confirms porch 142, garage 516 and deck/WDD 862.7 sq ft; these are separate from heated area.

Notes
The County building card records 4 bedrooms, 4.5 bathrooms and 3,749 square feet of heated area. The tables provide a starting point for comparing the home’s recorded layout and features; current condition and alterations should be confirmed through a property visit and current documents.
The County notice limits the reported characteristics to the first building only. The account records DUP-TRIPLEX and one unit; this is an account/building profile, not an independent survey or determination of exclusive dwelling allocation, legal configuration or current condition. Recorded land area is account-level. Exposed transfer/deed/plat entries were metadata, not underlying scans. The linked B0625/P0466 declaration identifies a different account, R011887, and is not used to establish facts for this property.
The County lists M09-0263, dated November 24, 2009, with reported value $4,180, and B09-0197, dated August 31, 2009, with reported value $245,282; both are labeled ADDITION and CLOSED. Detailed plans, allocation and completion documents were not exposed. Their relationship to the recorded 1984 actual and 1995 effective years is not established. Those County years are retained; closed status does not independently establish completed scope or current condition.

Map centered on the County address point linked to account R011888 and parcel 2101-122-19-015. The Assessor and County GIS identify unsuffixed 3987 Lupine Drive; Google directions labels this point 3987 Lupine Dr B. Google’s suffix is a secondary label, not evidence of an official County B designation or a verified entrance. This is an approximate account-linked location, not a surveyed boundary or allocation of exclusive access. Confirm the correct entrance before visiting.
