Description:

Siting and Setting Description:

The property lies within a residential block in Boise's East End, following the neighborhood's angled street grid. It fronts E Jefferson St and occupies an approximately level lot with concrete sidewalks, a planted setback, mature trees, and alley service access. The documented neighborhood development era and construction date are not established in the supplied record.

Main Building Description:

The photographed resource is a not evident-story building on a mid-block lot. Its principal façade faces not evident, fronting not evident. The photographed parcel is an active excavation or redevelopment site enclosed by temporary construction fencing. No principal residence is visible within the open work area. Neighboring houses appear at both sides and beyond the excavation. A small, one-story, front-gabled building at the alley edge has horizontal wood siding, plain trim, and an asphalt-shingle roof, but its parcel association and function are not established.

Features:

– Open excavated parcel with no visible principal building.

– Probable one-story gabled rear outbuilding with horizontal wood siding.

– Alley access and temporary construction enclosure.

Summary of Known or Observed Alterations:

– Unknown date: The principal building shown on the printed block map is not present in the September 2026 photographs.

– Unknown date: The extent and date of demolition or new construction are not documented in this record.

Accessory Building Description:

– No principal building is visible in the supplied photographs

– (1) probable detached rear outbuilding; function, parcel association, date, and contribution unresolved

Justification of Significance and Integrity:

Statement of Significance:

The construction date is unknown. The photographs do not document a standing principal residence. The open construction site cannot contribute architecturally under Criterion C in its present photographed state. The rear outbuilding requires separate parcel and chronology review before any recommendation. Confirm whether ICRIS requires a site record, a demolished-resource update, or a new-construction record.

Contributing Determination:

This is a pending recommendation. The recommendation applies only to the main building unless an accessory resource is expressly evaluated. Confirm the construction date, applicable district boundary, and period of significance before finalizing the ICRIS field.

Evaluation of Integrity under Criterion C:

– Location: The resource remains on the mapped parcel and maintains its relationship to the street and alley. Historic location has not been independently documented.

– Design: The visible massing, roof form, openings, and entrance treatment continue to convey the identified not evident. Any unresolved feature is named above.

– Setting: The sidewalk, planted setback, mature canopy, nearby dwellings, and alley service pattern preserve a coherent residential setting. Recent work on adjoining parcels is noted where visible.

– Materials: The photographs support the present material identifications of horizontal wood siding on probable rear outbuilding and asphalt shingles on probable rear outbuilding. They do not establish which components are original.

– Workmanship: Visible trim, porch elements, roof-edge details, and wall treatments retain evidence of the building's exterior design; concealed or replaced work is not assumed.

– Feeling: The building's scale, setback, roof form, and street presence continue to express an older residential character except where the record remains pending.

– Association: Under the proposed Criterion C basis, the relevant association is with the not evident type expressed by the surviving form and detail. No architect, builder, event, or person association is established.
