Initial analysis

The property at 1383 31st Avenue in San Francisco's Central Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1947, currently owned by Christine S K Wu 2012 Family Trust. The building has undergone several significant modifications and faced various maintenance challenges over the years. In 2001, substantial interior improvements were made including the addition of bedrooms, laundry facilities, and bathrooms at the ground floor at a cost of $11,000. A major set of violations was documented in April 2001, revealing multiple safety and maintenance issues including missing handrails, inadequate security features, damaged shower stall ceilings, malfunctioning doorbells, and various interior surface problems, along with concerns about combustible storage in the garage area. These violations were all abated by September 2001.

More recent developments include a 2016 street space permit and a 2020 complaint regarding construction activities for an in-law unit at the ground level, though this complaint was marked as not active. The building has experienced recurring parking enforcement issues, with numerous citations issued between 2022 and 2024 for vehicles blocking driveways. The property underwent some exterior repairs in 1998 focused on the stucco and garage area. The most recent municipal interactions have primarily involved parking violations, with ten documented cases between 2022 and 2024, suggesting ongoing challenges with parking management in the vicinity of the property. Temporary restrictions due to the COVID-19 pandemic were noted in 2020 regarding unit occupancy.

Risk rating

How 1383 31St 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.
