449-451 34th Ave, San Francisco, CA 94121

The property at 449-451 34th Avenue in the Outer Richmond is a three-story, multi-family residential building constructed in 1900, currently containing two units. The most significant recent development was a major conversion completed in 2008, where the building was transformed from a two-story single-family residence into a four-story, two-unit residential building through substantial vertical and horizontal additions, with a construction cost of $928,000.

This renovation project included comprehensive updates to the building's systems, as evidenced by subsequent permits in 2012 showing the installation of new fireplaces, furnaces, kitchen hoods, and an extensive electrical upgrade with 200 amps main service, three meters, and numerous electrical fixtures and appliances. The building underwent several critical infrastructure improvements in the late 1980s, including foundation work in 1986-1988, and received additional renovations in 2012 involving structural revisions, floor plan updates, and the addition of two fireplaces. A minor building complaint was filed in December 2012 regarding unauthorized work on a stairwell wall, though this was promptly addressed.

The property has seen regular maintenance and compliance with safety standards, including the installation of 16 smoke detectors during the 2012 renovations. While there have been multiple 311 calls related to parking violations and sidewalk access issues between 2020-2024, these do not directly reflect on the building's conditions or management. The most recent building activity includes reports of abandoned furniture and debris on the street outside the property in late 2024, though these were promptly resolved by city services.
