Initial analysis

The two-unit, two-story multi-family residential building at 1390 23rd Avenue in San Francisco's Central Sunset neighborhood, built in 1991 and currently owned by Mary Lye Shan Lee and Shofiel, has a notable history of waste management and sidewalk maintenance issues in recent years. The most significant concerns relate to improper toter management, with three documented cases between November 2021 and January 2022 regarding garbage bins being left out continuously, leading to enforcement actions and re-inspections. The property has also experienced recurring issues with street cleanliness, including multiple 311 calls for garbage and debris between 2023 and 2024, with the most recent incidents involving loose garbage and debris, though these cases were resolved with no significant findings or nothing found upon inspection.

The building's permit history shows relatively minimal major modifications, with three main records: a 2007 permit for street space and sidewalk work (issued), a completed vertical addition in 1989, and an expired permit from 1987 for non-structural kitchen and bathroom work. More recent incidents (2022-2024) primarily involve street maintenance and parking enforcement, including two cases of driveway blocking in February 2022, sidewalk blockage by a residential toter in February 2022, and various cleaning issues involving city garbage cans or street waste, some of which were duplicate service requests or resolved without significant findings. While these issues primarily relate to street and sidewalk maintenance rather than structural or safety concerns within the building itself, they indicate an ongoing challenge with waste management practices in the immediate vicinity of the property.

Risk rating

How 1390 23Rd 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
66th percentile

Out of 814 buildings in this neighborhood, 277 are predicted to be safer.
