1827-1829 Union St

I am under contract to purchase the property located at 1827 Union Street, San Francisco, CA 94123, and respectfully request a Letter of Determination confirming whether the proposed use of the ground-floor commercial space as a medical dermatology clinic is permitted under current zoning and applicable San Francisco Planning Code provisions. The proposed use consists of a physician-led dermatology medical office providing outpatient medical, surgical, and cosmetic dermatologic services, with exam rooms, treatment rooms, and administrative space. No overnight patients or inpatient care. The clinic would also include ancillary sales of medical-grade skincare and haircare products that are accessory to and customarily associated with the dermatology practice, intended primarily for existing patients as part of treatment plans. Retail activity would be subordinate to the primary medical use and would not operate as a standalone retail establishment. I respectfully request confirmation of whether this proposed use qualifies as Medical Services and/or Professional Services under the Planning Code, and whether such use is permitted or conditionally permitted at this location, including any applicable ground-floor use controls or special use district requirements. This request is made to confirm zoning compliance prior to occupancy and permit application.
