Exterior rehabilitation of secondary structure. Existing garage to be converted to accessory dwelling unit.

Replacement of existing metal roof with new asphalt shingle roof cladding. Replacement of existing 1/1 double-hung windows with new wood 1/1 double-hung windows on the south elevation (facing rear of house). Replacement of wood door with a new four-light door. On the east elevation, the garage opening will be enclosed with a wood clad, full-light screen door on the right side. T-111 plywood siding on gable fields to be replaced with wood shakes.

1. 1909 Washington Ave is a contributing resource to the Edgewood-Park City and the local overlay. The NRHP nomination notes a one-story frame garage with composition siding; the existing secondary structure is a one-story, CMU garage with a CMU exterior.

2. All work is concentrated on the secondary structure; no work is proposed for the main house.

3. Overall, the proposed scope of work meets the design guidelines. The proposed roofing, windows, and door materials are appropriate for the context. Replacing the sliding garage door with additional transparency in full-light patio doors will contribute to the structure. No historic materials or design elements are proposed to be modified.
