Initial analysis

The two-unit residential building at 675-677 14th Avenue in San Francisco's Central Richmond district is a two-story flats and duplex structure built in 1924, currently owned by the Charles C Martin Living Trust. The property has undergone several significant improvements over the years, with the most substantial renovations occurring in 2005, when major interior work was completed including kitchen and bathroom remodels, sunroom improvements, and electrical upgrades totaling approximately $260,000. This comprehensive renovation included the installation of 110 lights, 65 switches, 100 receptacles, 40 circuits, two 100-amp sub panels, and a 200-amp service rewire for both units. A recreation room was added in the basement in 1986, and more recently, there was a street space permit issued in 2017.

The building's maintenance record shows regular upkeep, including a $10,000 reroofing project completed in 2005. The property has experienced limited external issues, with three notable incidents recorded through the 311 system: a 2021 incident involving medical waste (needles) that was promptly addressed by park services, a 2017 case of offensive graffiti that was resolved by the Department of Public Transportation, and a 2015 park structural maintenance issue regarding pavement that was addressed by park patrol. These external incidents appear to be related to the surrounding area rather than the building itself, and there are no documented safety concerns or patterns indicating recurring issues with the property.

Risk rating

How 675-677 14Th 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.
