451 Buena Vista Ave, San Francisco, CA 94117

The two-family residential building at 451 Buena Vista Avenue, owned by Kirk Philip John, was constructed in 1939 and has undergone significant improvements and renovations over recent years. Most notably, between 2018 and 2020, the property underwent substantial modernization including the installation of a comprehensive fire sprinkler system ($27,306), new retaining walls in the rear yard ($25,000), and the addition of skylights ($1,000). The building received major infrastructure upgrades including a 200-amp electrical panel upgrade, whole-house wiring remodel, and the installation of two new boilers and forced air systems.

Several plumbing and electrical permits were completed successfully, demonstrating consistent maintenance of building systems. The property has experienced some resident concerns during its renovation period. In 2020, there were multiple complaints about construction noise, unauthorized plumbing work in the ADU, and excessive lighting affecting urban wildlife.

In 2013, the building incurred minor damage from a vehicle collision, leading to multiple notice of violation (NOV) filings, though these were ultimately resolved by late 2014. The building's recent improvements included the addition of a new dwelling unit on the ground floor (not considered an ADU), installation of new rear yard fences, and various facade improvements. Planning records show proper permits were obtained for these enhancements, and the building now meets updated safety and accessibility standards through the installation of modern fire safety systems and infrastructure upgrades.
