482-486 Duboce Ave, San Francisco, CA 94117

The three-story multi-family residential building at 482-486 Duboce Ave in Hayes Valley, owned by Lozano-batista Stack Family LLC, was constructed in 1900 and contains four apartment units. The property has undergone several substantial improvements over the years, with the most significant recent upgrades including a complete reroofing project completed in 2015 costing $59,246, the installation of 20 roof-mounted solar PV modules in 2015, and a 400-amp electrical service upgrade in 2005.

More recent improvements include the installation of a gas fireplace in 2021 and a kitchen range circuit installation in 2019. The building had a series of violations in 2009 related to safety and maintenance issues, including requirements for handrails, fire extinguishers, security features, and gas meter instructions, all of which were resolved by June 2009.

Earlier renovations of note include kitchen and bathroom remodels in 2005, along with kitchen rewiring and plumbing work. The property has maintained a relatively clean record since the 2009 violations were addressed, though there have been several recent 311 calls (2023-2024) primarily related to street-level maintenance issues such as graffiti, illegal postings, and sidewalk cleaning needs, which appear to be promptly resolved by city services.
