159 Peralta Ave, San Francisco, CA 94110

159 Peralta Avenue is a two-unit, two-story multi-family residential building located in Bernal Heights, constructed in 1914 and currently owned by Pappu Narayana and Rubin Aman. The building's maintenance history shows regular upkeep, with recent significant improvements including the installation of a solar power system in 2019 (though this permit has expired) and window replacements in 2016. Earlier maintenance work included plumbing updates with a house trap and sewer line replacement in 2012, water heater replacement in 2007, and multiple window retrofits between 1994 and 2007.

Structural improvements incorporated reinforced concrete work on the front stairs in 2011. The property has a documented history of addressing code compliance issues, including the legalization of a shower and storage room in 1996 following a complaint about possible illegal unit rental, though a similar complaint was filed in 1996 and not fully resolved until 1998. Recent infrastructure and maintenance challenges have been mostly external, with multiple parking enforcement issues in late 2023 and early 2024 involving vehicles blocking driveways, primarily Teslas.

There were also two collapsed sidewalk complaints in November 2021, one of which remains open, and an overgrown tree issue reported in April 2022 that was addressed through regular maintenance scheduling. The building's plumbing system appears to have received attention in recent years, with both the sewer line and water heater being replaced, though no more recent plumbing permits are on file. The electrical system received a solar upgrade in 2019, representing a move towards sustainable energy use. While there have been some historical complaints and permit issues, most recent records indicate regular maintenance and compliance with building codes, with particular attention to essential systems like plumbing and electrical.
