1234 12th Ave, San Francisco, CA 94122

The 6-unit, 2-story multi-family residential building at 1234 12th Ave in San Francisco's Inner Sunset neighborhood, owned by Ugo I & Loreta Colabianchi, has undergone several significant safety improvements and faced ongoing maintenance challenges since its construction in 1963. Most notably, the building completed a mandatory soft-story retrofit in 2017 at a cost of $68,000, demonstrating compliance with seismic safety requirements. The property has experienced recurring moisture-related issues, with documented complaints of water intrusion, window problems, and mold between 2012 and 2015, particularly affecting ground floor units and window areas, though these issues were generally resolved through routine housing inspections.

Historical violations from 2002 regarding fire safety equipment and gas utility shutoff requirements were promptly addressed within weeks of identification. The building received a new roof in 2010, and a recent fire alarm system complaint was filed in early 2025, though the resolution status remains unclear. The surrounding area has experienced typical urban issues as evidenced by various 311 calls, including multiple parking violations and street cleaning requests.

Recent reports from 2024-2025 mostly pertain to external matters not directly related to the building's condition or management. The property has maintained compliance with major safety requirements, as indicated by the completion of the soft-story retrofit and the resolution of historical violations, though the 2025 fire alarm system complaint warrants attention. The building's maintenance history suggests a pattern of addressing violations and complaints in accordance with regulatory requirements, with most issues being resolved within reasonable timeframes.
