Initial analysis

The property at 1401-1403 43rd Avenue in San Francisco's Outer Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1945, currently owned by Fanny Ching Owyoung Survivo. The building has a documented history of stairway maintenance issues, with repairs carried out in 2004 and again in 2021, including replacement of pressure-treated treads in the rear exterior stairway. Most concerning is a building complaint filed in July 2021 regarding mold issues in the lower unit, specifically black mold that allegedly persisted despite testing and recommendations for removal, though this complaint is listed as "Not Active" in the system. The building's history also shows attention to basic infrastructure maintenance, including reroofing work completed in 2001 at a cost of $8,000.

More recently, the property has experienced multiple garbage and debris-related incidents in January 2025, with at least eight reports of overflowing city garbage cans and other debris issues, though these are primarily related to street conditions rather than the building itself. The only recorded fire incident was related to electrical equipment in the vicinity of the address, though no civilian injuries were reported. The property's maintenance history shows regular upkeep of critical elements like stairs and roofing, but the documented mold issue from 2021 stands out as the most significant resident health concern in the available records.

Risk rating

How 1401-1403 43Rd 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
46th percentile

Out of 632 buildings in this neighborhood, 341 are predicted to be safer.
