Notes
The County building card records 4 bedrooms, 5.5 bathrooms and 3,679 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, lawful configuration or current condition. Recorded land area is account-level. Exposed transfer, declaration, plat and abatement entries were metadata, not underlying recorded documents.
The County lists five 2022 permits with status CLOSED: B22-0072, B22-0072.001, B22-0072.002, A22-0049 and E22-0090. The sketch labels additions as 2022. Permit summaries do not expose detailed plans or actual closeout evidence, and the relationship of this work 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.
