The 15,572-square-foot project site (Assessor’s Block 2088, Lot 088) is located in the Western Addition neighborhood at the northwest corner of Fillmore and Fell streets on a block bounded by Fell Street to the north, Webster Street to the east, Oak Street to the south and Fillmore Street to the west (see Figure 1: Project Location). The site is within the boundaries of the Hayes Valley Residential Historic District. The proposed project site is part of the Sacred Heart Parish Complex grouping consisting of a church, rectory, school, and convent. The project site is occupied by a 20,046 square foot church building currently used as the Church of 8 Wheels, a roller-skating venue and formerly used as the Sacred Heart Church. The structure is a basilica style church with an attached campanile consisting of a one-story, open floor plan with mezzanine (former choir loft) over a full basement. The proposed project would involve conversion of the former church building to residential use by inserting five new floors into the structure, as well as adding a new basement and sub-basement. This would accommodate five market rate dwelling units totaling approximately 14,950 square feet, 36 market rate group housing units comprising about 32,900 square feet, and about 11,250 square feet of shared common space. The individual residential units would include four two-bedroom units and one three-bedroom unit. The proposed project would also include 3,900 square feet of parking for 15 vehicles in the sub-basement level, as well as 60 Class I bicycle parking spaces in the sub-basement level as well as two Class 2 bicycle parking spaces at street level. The proposed project would increase the building’s size from the existing 20,046 square feet to 66,000 square feet, including the basements. Proposed exterior alterations include new glazing in the existing window frames, nine new cutouts on the roof for the proposed roof decks, and new skylights to meet lighting requirements. The proposed project would also include the installation of an interior elevator, mechanical equipment upgrades, seismic upgrades and a new fire-fighting protection system. The size and massing of the building would not change.
