Initial analysis

The property at 1843 9th Avenue in the Inner Sunset is a two-unit, two-story multi-family residential building constructed in 1984, currently owned by the James & Margaret Chan Revocable Trust. The building's maintenance history shows regular upkeep of the roof, with the most recent reroofing project completed in July 2024 at a cost of $20,989, following a previous reroofing completed in 1995, indicating attention to building maintenance over time. The construction and erection permits from 1983-1984 are also on record, demonstrating proper adherence to building regulations during initial construction.

The property has experienced several incidents related to parking and street maintenance in recent years, with a notable cluster of driveway-blocking incidents occurring between May and June 2022, resulting in multiple citations being issued. There were also two graffiti incidents reported in February 2020, one on the street and another on a pole, though these were subsequently resolved. The area has seen occasional issues with abandoned vehicles, with two such reports in February 2020, one resulting in towing, while two driveway-blocking incidents from 2021 and 2022 were resolved either through citations or other enforcement actions. The most recent non-building related issue was a litter receptacle maintenance call in July 2024, which was resolved, but this appears to be related to street maintenance rather than the building itself.

Risk rating

How 1843 9Th 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.

Neighborhood percentile

Out of 1493 buildings in this neighborhood, 194 are predicted to be safer.
