55-57 Sharon St, San Francisco, CA 94114

The property at 55-57 Sharon Street is a two-unit, two-story multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood. Built in 1900 and owned by the Elizabeth M Balaqui Revocable Trust, this flats/duplex structure has undergone several significant improvements over the years. Notable historical maintenance work includes complete reroofing in 2000 ($8,000), removal of two earthquake-damaged chimneys and installation of a new fireplace in 1990 (completed), and foundation work with mudsill and concrete garage replacement in 1987 (completed).

In 2009, the building was upgraded with both solar thermal collectors for domestic hot water and a photovoltaic solar panel system, demonstrating a commitment to sustainable energy use. The property has experienced some regulatory activity, including a cancelled 1992 permit application for adding a studio unit and garaged parking space, and more recently denied requests for a parking variance to add a third unit to the basement. A building complaint was filed in 2017 regarding a disrepair of a wooden fence, raising safety concerns about a potential fall hazard. The property has generated multiple 311 calls in recent years (2020-2025) primarily related to street cleaning, parking violations, and waste removal, though these issues appear to have been resolved promptly.

Most recently, there was a report of illegal construction without proper permits in January 2025, which was closed after being transferred for further tracking. The building's permit and violation history indicates regular maintenance and upgrading of systems, with most historical issues being promptly addressed. The denial of recent unit expansion requests suggests compliance with current zoning and building regulations. The most pressing concern appears to be the recent illegal construction complaint, though without more current information on its resolution status.
