The Historic Preservation Commission on Nov. 3 held (continued) consideration of a certificate of appropriateness for rehabilitation and a three‑story rear addition at 501 East Historic Mitchell Street, submitted by St. Stanislaus Properties LLC. Staff presented extensive plans showing masonry repairs and replacement, new solid wood windows, a stepped three‑story addition set behind the historic façade, and a rooftop terrace with mechanical screening not visible from the right of way.

Staff recommended approval with conditions: a detailed window schedule for staff review, use of non‑clad solid wood windows (with simulated divided lights if applicable), restoration of two historic multi‑light windows on the Fifth Street façade if they remain, replacement of incompatible coach lights on the rear entry with fixtures more consistent with the building’s period, review and city approval of masonry cleaning/paint removal procedures, and retention of the historic six‑course common bond on the existing historic masonry while permitting a running bond on the new addition.

During discussion commissioners and the applicant focused on how to make clear what is historic and what is new. Several commissioners urged a clearer visual separation of the addition from the historic building—options discussed included a slightly different brick color or texture, a discreet joint or “gasket,” or a small additional setback. The applicant’s architect said the project team had considered material differentiation but the client preferred a cohesive look; staff and commissioners requested further exploration of subtle material or detailing changes that would better distinguish new work from the historic fabric without sacrificing the program’s required square footage.

A motion to hold the item to the next monthly meeting was made, seconded, and carried to allow the applicant and staff to refine the east‑façade connection details and to permit limited staff review of minor follow‑up refinements. The applicant indicated a willingness to work with staff promptly; the commission authorized staff to review minor revisions and requested the applicant provide additional images and details for the east façade before the next commission meeting.
