Notes
The County building card records 4 bedrooms, 4.5 bathrooms and 3,369 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 2026 County notice limits characteristics to the first building. The building card records DUP-TRIPLEX and Units 1; these assessment labels do not independently establish lawful dwelling configuration, per-dwelling allocation, exclusive frontage or entrances. No allocation is inferred. The historical photograph includes adjoining frontage and cannot establish exclusive #1 frontage or current condition. Extra-feature counts are not dwelling counts.
The sole exposed permit B08-0004 records an $800,000 ADDITION issued January 10, 2008 and CLOSED. Detailed approved plans, added-area allocation and completion documents were not exposed, and the records do not explain its relationship to the retained County actual/effective years 1992/2000. The permit summary does not establish present condition or completion of a specific scope; no added area or revised building year is inferred. Transfer/plat entries were metadata only, without underlying scans. Stronger claims about the addition require authoritative plans or closeout evidence.
