524-526 Vermont St, San Francisco, CA 94107

The property at 524-526 Vermont Street is a 1-story, multi-family residential building located in San Francisco's Potrero Hill neighborhood. Built in 1900 and owned by Lin Albert Mcelroy Pam, this two-unit residential building has undergone several significant renovations and maintenance work over the past few decades. The building's most recent official documentation in September 2021 confirmed its legal use as a two-unit residence, following a review of city records and a site visit.

Notable historical improvements include the replacement of nine windows and one patio door in 2005 ($5,600), dry rot repairs and siding work in 2006 ($16,280), and a sewer line replacement in 2009. Earlier modifications included interior staircase improvements to an attic bedroom in 2001 ($2,500) and a horizontal addition planned in 1997 (permit expired). The property has experienced recurring issues with driveway blockages, with three documented incidents between June 2022 and July 2024, all of which were resolved through parking enforcement intervention.

Other recent exterior concerns included a defaced parking sign in July 2018, a burnt-out streetlight in November 2017 (though this was under CalTrans jurisdiction), and another streetlight issue in January 2014 that was promptly addressed. An encampment-related concern was reported in October 2019 but was found to be resolved upon inspection. The building's maintenance record shows regular upkeep of essential systems, though some permits from the early 2000s (for reroofing and a horizontal addition) expired without recorded completion.
