41-43 Prosper St, San Francisco, CA 94114

The building at 41-43 Prosper Street is a two-unit, two-story multi-family residential structure located in the Eureka Valley/Dolores Heights neighborhood. Built in 1900 and currently owned by the Peneyra Maria A 98 Revoc Tr, this flats and duplex building is undergoing significant renovations as evidenced by the recently filed permit (September 2024) for substantial improvements including kitchen and bathroom relocations, addition of new bathrooms, conversion of a ground floor storage area into an office with bath and wet bar, exterior upgrades including new wood siding and windows, and removal of the rear stair for fire department access modifications.

The property has a history of parking-related issues, with multiple documented cases of driveway blocking between 2020 and 2024, resulting in several citations, though some cases could not be validated or located. A notable tenant buyout occurred in December 2023, with the property owner compensating two tenants a total of $95,000.

Additional improvements on record include window replacements in 1997 and a water heater replacement in 2007. The property is currently undergoing review for a variance related to rear yard encroachment concerning the proposed stair and landing modifications, with an associated application for renovation and structural retrofit under review by Trichome Architects Inc.
