Staff Recommendation

Staff recommends approval of Certificate 2-F-25-IH, subject to the following conditions: 1) final site plan to meet City Engineering standards, including any modifications to the right-of-way access, with major changes to the site plan to return to the DRB; 2) incorporation of additional design elements to meet Middle Housing standards, with approval and minor revisions to be approved by staff; 5) revision to side elevation window placement; 6) meeting all relevant standards of Article 4.6.

Applicant Request
New Primary Structure
1. The applicant intends to use Section 4.6 of the zoning code, the Middle Housing standards, which are "intended to promote the development of neighborhood-scale housing forms which are compatible with existing housing in the surrounding area," and "may allow more flexible development of land than is possible under the base district zoning regulations," subject to additional dimensional, design, and parking standards. Middle Housing review occurs separately through Planning staff; the DRB review focuses on how the project meets the Infill Housing design guidelines. However, some elements of Middle Housing review may trigger site plan and building elevation revisions, which would require additional review by the DRB.

2. There are no other houses on the blockface to receive new construction. The building is proposed to be set 20' from the front property line, which is appropriate for a block with no other structures. The site plan contains a concrete walkway to the street.

3. The guidelines for multi-unit housing recommend that "new multi-family buildings be designed in scale and context with the early architectural features of the neighborhood." The block to receive new construction has no other structures; the buildings across the block are the rears of buildings fronting Ohio Avenue. The two-story duplex will lack context in the area. The duplex is proportionate to the dimensions of the large (83' wide) lot and features consistent side setbacks. It does not incorporate many details which align with the architectural context. Additional design elements are also required by the Middle Housing standards.

4. There is no parking provided on the site plan (as the site is within a quarter-mile of a transit route, off-street parking is not required by the MH standards). The duplex is proposed for a dead-end street with no turn-around, with an approximately 10' pavement width, which may not permit two-way traffic. The pavement does not extend in front of the full property width. Revisions may be necessary to the site plan or road conditions to meet City Engineering standards. Major revisions which affect the site plan may require further DRB review.

5. The 35'-4" wide duplex is compatible in façade width with original houses in the neighborhood and meets the maximum building width requirements in Article 4.6, Middle Housing standards, for a side-by-side duplex. Guidelines also recommend that multi-unit housing be similar in height to original houses on the street. The two-story building is taller than the surrounding context, as the block across the street is characterized by one-story houses. The side elevations are large in scale but attempt to break up the massing with a bay window on each side and trim separating each story. The building is within the maximum depth for a side-by-side duplex in the Middle Housing Standards.

6. While the proposed entry stoops are not 8' deep per the guidelines, similarly-designed entry stoops have been approved for multi-unit buildings in the Infill Housing overlay. The entry stoops are relatively small in scale.

7. At least a 6/12 roof pitch is required in the Middle Housing standards to fill the "steep" category of roofline; 6/12 is also the minimum pitch approved by the Infill Housing guidelines. The large building may also benefit from additional variations in roofline, particularly on the larger side elevations.

8. Guidelines recommend window and door styles be similar to historic houses on the block, with similar placement and ratio of solid to void. While all four elevations feature sufficient transparency for the historic context, some revisions may be necessary to better align the buildings with the historic context (including the irregular placement of windows on the side elevations).

9. The elevation drawings feature horizontal siding (no materials provided) and a stucco-clad CMU foundation. The siding should feature a horizontal overlap similar to wood siding instead of Dutch lap or flush panes.

10. The final site plan should incorporate native or naturalized shade trees in the front and rear yards, or retain any existing mature trees on the site.

Staff Comments
New primary structure (duplex) fronting Apricot Avenue. Two-story building features a side-gable roof (6/12 pitch), an exterior of lap siding with corner boards and cedar-texture accent boards at the top of each story, and a block foundation clad in stucco. The duplex is 34' wide by 50' deep (two adjacent units of 17' wide by 50' deep) and will be set 20' from the front lot line. Each unit features a 6'-9" wide by 4'-5" deep front porch at the edge of the façade, and the porches are recessed under a front-gable roof supported two square posts. The site plan does not feature any parking.

The façade (south) features four bays, and the two central bays contain a two-story, paired front-gable massing that projects 4'-5" from the façade, with two windows on each story. The left and right bays each feature a porch with a paneled door and a window on the second story. All windows on the duplex are 1/1 and double-hung. The left and right elevations each feature three windows on the first story, one of which is a box bay window that projects 1'-6" from the main massing with a half-hipped roof, and there are two windows on the second story. Side elevations feature large swaths of "cedar texture architectural ascent board" as trim between the first and second stories. The rear elevation features two windows and a secondary entrance for each unit on the first story, and the second story features four windows.
