Initial analysis

The two-unit residential building at 40-42 Richardson Avenue in the Marina neighborhood, owned by the Doris M. Giuliotti 1991 Trust, has undergone several significant improvements since its construction in 1940. The property has received regular maintenance and upgrades, including two complete reroofing projects (1990 and 2006), a major kitchen remodel in 2004-2012 involving both plumbing and electrical work (valued at $43,000), and window replacements in 1997. The kitchen renovation, completed in 2012, included new lighting, cabinets, countertops, and appliances, with associated electrical work totaling $8,000.

The building's recent history shows attention to maintenance and infrastructure upgrades, including the installation of a 100-amp electrical panel in 2004 and various street space permits. A complaint in 2006 regarding an unauthorized penthouse addition was quickly addressed and abated within one month. The property has experienced typical urban issues in its vicinity, as evidenced by recent 311 calls between 2021 and 2024, including cases of graffiti, sidewalk cleaning, hazardous materials investigation, and tree maintenance matters. Most of these issues have been promptly resolved, though there is currently an open case from August 2024 regarding a knocked-down street lighting pole. The building's maintenance record demonstrates regular upkeep and modernization, with no indicated safety concerns or recurring maintenance issues.

Risk rating

How 40-42 Richardson Ave'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.
