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 one-and-one-half-story building at the intersection of E Jefferson Street and N Elm Avenue. Its principal façade faces north, fronting E Jefferson St. The corner residence presents a broad one-and-one-half-story front composition with a side-gabled main roof, a projecting front gable, and a recessed porch extending across the remaining façade. Horizontal lap siding covers the walls, and a brick chimney rises at the east side. The porch has square posts, an open railing, and a central entrance reached by a straight walk. Alley photographs show a detached gabled garage and a taller rear volume. The relationship of that volume to the main house and the separate 223 N Elm label on Map 2 is unresolved. Character-Defining Features: – Broad side-gabled body with a projecting front gable. – Recessed porch with square supports. – Horizontal wall cladding and brick chimney. – Detached gabled alley garage. – Taller rear volume requiring association review. Summary of Known or Observed Alterations: – Unknown date: The porch railing, entry, and some window assemblies appear renewed. – Unknown date: A taller rear volume may be an addition or separate resource. – Unknown date: The detached garage's date is unknown. Accessory Building Description: – (1) main house; preliminary recommendation: contributing, subject to rear-volume review – (1) detached gabled garage at the alley; contribution pending chronology – Possible separate rear or side resource associated with 223 N Elm Avenue; count unresolved

Justification of Significance and Integrity

Statement of Significance: The construction date is unknown. The house retains a coherent gabled form, porch, chimney, and residential setback that support a preliminary Criterion C district contribution. The principal Jefferson elevation remains legible. The rear volume and Map 2's 223 N Elm label require resolution before finalizing feature count or extending the recommendation beyond the main house. Contributing Determination: This is a preliminary contributing 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 gabled vernacular residence. 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 lap siding; substrate not evident and asphalt shingles. 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 gabled vernacular residence type expressed by the surviving form and detail. No architect, builder, event, or person association is established.
