257-259 Peralta Ave, San Francisco, CA 94110

The property at 257-259 Peralta Avenue is a two-unit, one-story multi-family residential building located in Bernal Heights, owned by Judith F. Ocallaghan and Albe.

Built in 1900, this flats and duplex structure has undergone several significant improvements over the years, with the most substantial renovations occurring in 2007 when major interior alterations were completed, including kitchen and bathroom remodels, installation of new beam and footings, window replacements, electrical upgrades (including installation of lights, switches, receptacles, and circuits), and plumbing work for two fireplaces. Earlier improvements included legalizing its use as a two-family dwelling in 1995, reroofing in 1993, and structural safety enhancements such as anchor bolt installation in 1996. The property has experienced several environmental and urban issues in recent months (as of 2024), most notably a series of tree-related incidents, including reports of one or more fallen or damaged trees in November 2024, with one case still marked as open regarding an about-to-fall condition.

There have also been multiple reports of illegal parking in the vicinity between September and October 2024, though enforcement officers were generally unable to validate the complaints or locate the vehicles in question. A single fire-related complaint regarding combustible materials was filed in April 2013, but was determined to have no merit. The building's maintenance history suggests regular upkeep and improvements, with no recent structural or safety concerns directly associated with the building itself.
