519 Guerrero St, San Francisco, CA 94110

The 11-unit, three-story apartment building at 519 Guerrero Street, owned by Connolly Exemption Trust, was originally constructed in 1922 and has undergone various renovations and faced multiple regulatory scrutiny over the years. Most recently, the building has seen significant infrastructure improvements, including the conversion of a storage room to a laundry facility completed in early 2024, along with a substantial electrical upgrade to a 400-amp service with 12 meters. The property has also made efforts to address fire safety concerns, with a 2023 upgrade to the fire alarm system and the installation of low-frequency sounders in sleeping areas to meet fire code requirements.

The building has faced several compliance challenges, particularly in recent years. In September 2023, active violations were noted regarding lead paint concerns, fire proofing materials, smoke/carbon monoxide detector compliance, and general building maintenance. A pattern of building safety issues emerged from a 2002 routine inspection, which identified problems with stairs, fire escape maintenance, security features, and fire proofing materials, though these were subsequently abated.

The property has experienced regular fire safety inspections, with violations noted in 2021 regarding fire extinguisher testing, exit maintenance, and building owner contact requirements, all of which were abated. While the building's systems have been progressively upgraded, as evidenced by the recent permits and completed fire safety improvements, the active violations from 2023 indicate ongoing maintenance and compliance challenges that require attention. The surrounding area has had its share of typical urban issues, with several 311 calls recorded between 2015 and 2023 primarily related to street cleaning matters.
