2099 Quesada Ave, San Francisco, CA 94124

The two-unit residential building at 2099 Quesada Avenue in Silver Terrace, owned by the Lao Family Trust, has a complex compliance history and several ongoing concerns. Built in 1908, this two-story flats and duplex structure has faced multiple regulatory issues, most notably regarding unpermitted construction. An active violation from 2019 (NOV #201905171) regarding an unauthorized garage structure at the rear of the property remains pending closure, although a 2022 permit was issued to remove covered garage roof and doors while retaining an open car-port.

The property has a documented history of unpermitted work from 2006, including a horizontal addition, metal garage construction, CMU wall extension, unauthorized re-roofing, and kitchen remodeling, which triggered multiple notices of violation. These violations were eventually abated by 2008. Recent activity at the property has shifted focus to exterior maintenance and surrounding area conditions, with multiple 311 calls in late 2024 regarding garbage, debris, and illegal parking.

The most recent building permit activity involves compliance with the 2019 violation regarding garage modifications, though there are still questions about additional unpermitted work that may have occurred. While historical fire and safety concerns from 2019 and 2006 have been addressed, there are currently no active fire safety violations on record for this address, though there have been multiple recent violations noted at an adjacent address (2055 Silver Ave) that may warrant attention. The building's long history of permit violations and compliance issues suggests a pattern of unauthorized modifications and construction work that has required ongoing oversight and remediation efforts by city authorities, though many of these historical violations have been resolved.
