Initial analysis

The two-unit residential building at 251 19th Avenue in San Francisco's Central Richmond neighborhood is a two-story flats and duplex structure built in 1922, currently owned by Masaharu M & Mimi M Ishikawa. The building's maintenance history shows several significant improvements over the years, with the most recent work being the replacement of two forced air furnaces, which was permitted in December 2024. Past building improvements include a completed bathroom remodel in 1994 that involved comprehensive updates including new plumbing and insulation, reroofing work, and the replacement of structural flashing at planter decks. The plumbing system has been regularly maintained, with the most recent furnace replacement indicating ongoing upkeep of essential systems.

The property has experienced several infrastructure-related incidents over the years, with the most significant being a sewage backup incident in January 2019 involving a 4-inch sewer vent. While not directly related to the building's condition, the surrounding area has experienced occasional street cleaning issues, with multiple reports of loose garbage in 2017, 2020, and 2022, all of which were resolved promptly by city services. Two abandoned motorcycle incidents were reported in July and September 2017, respectively, and one driveway blocking incident occurred in January 2019, though none of these directly impacted the building itself. The property's maintenance record, particularly the recent furnace replacement, suggests regular attention to building systems, while the limited number of repairs and basic infrastructure maintenance work required since the 1990s indicates stable, though aging, building systems typical of a nearly-century-old structure.

Risk rating

How 251 19Th 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.
