Initial analysis

The property at 1039-1041 Cabrillo Street in San Francisco's Inner Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1923, currently owned by Laura Monfredini and Gabel Ma. The building has undergone several significant renovations over the past decades, with the most substantial recent work occurring between 2020-2022, when a portion of the first-floor garage/storage area was converted into an accessory dwelling unit (ADU) featuring modern amenities and safety improvements including new electrical systems, plumbing, and a comprehensive fire sprinkler installation with 19 heads. Prior to this conversion, the building underwent various maintenance and upgrade projects including roofing work in 2017, kitchen and bathroom renovations in 2008, and earlier kitchen remodeling efforts dating back to 1988 and 2006. A notable incident occurred in 2012 when a complaint was filed regarding disrepair and vacancy, though this issue was quickly resolved within two days.

The property has had some external maintenance and neighborhood issues documented through 311 calls, including graffiti incidents (one in 2022 and another in 2020), a damaged tree report in 2020, and various street-related concerns such as pavement defects and hazardous materials in the vicinity. Most recently, there was a noise complaint filed in August 2024, categorized as a major event venue issue. While these external issues have been addressed through proper channels, they primarily relate to the neighborhood environment rather than the building's structural or safety conditions. The building's recent history shows significant investment in modernization and safety features, particularly through the ADU conversion project, which was designed with proper permits and inspections including structural, electrical, and plumbing upgrades compliant with current building codes.

Risk rating

How 1039-1041 Cabrillo St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
