633 27th Ave, San Francisco, CA 94121

The property at 633 27th Avenue in the Central Richmond is a three-story, two-unit multi-family residential building constructed in 1923, currently owned by Oneill Family Revocable Interv. The building underwent significant renovations in 2007-2011, including a major remodel that added a new basement and additional unit (completed at a cost of $325,000), installation of a comprehensive fire sprinkler system ($37,393), complete rewiring of the building with modern electrical systems, and plumbing updates. During this renovation period, several code violations were addressed, including one in 2012 regarding backflow prevention equipment.

Most recently, the building has experienced water-related issues, with a 2018 complaint about top apartment deck leakage affecting lower units. The property has a history of parking enforcement issues, particularly with driveway blocking incidents, with multiple enforcement actions recorded between 2022-2024. There are several active pavement defect reports from 2024 near the property.

The building's infrastructure upgrades from 2010-2011 included the installation of 61 sprinkler heads, a 200-amp electrical service with extensive wiring and safety features, and comprehensive plumbing improvements. The renovation period (2007-2011) was marked by significant transformations, including the addition of modern safety systems such as fire sprinklers and smoke detectors, while earlier maintenance work included reroofing in 1992. Historical building violations from 2010 noted blighted conditions with a broken front door and trash accumulation, though these issues were promptly addressed. Recent 311 calls have primarily concerned parking violations and street maintenance, with the most pressing recent concerns being related to pavement defects in early 2024.
