Initial analysis

1123 Stanyan Street is a two-story, four-unit multi-family residential building constructed in 1955, currently owned by Vaccaro Enterprises. The property has undergone several maintenance and improvement projects over the past three decades, with the most recent being the replacement of the vertical siding at the front facade in October 2019 at a cost of $6,800. Other significant building improvements include a 2003 reroofing project valued at $9,500, and a 1999 window replacement project where aluminum sliding windows were replaced with vinyl insulated windows. Routine housing inspections were conducted in 1999 and 2005, both of which were resolved without any continuing issues.

The property has experienced multiple infrastructure-related concerns in recent years, with several 311 calls recorded between 2018 and 2023. Most notably, there have been recurring issues with tree root damage to the sidewalk (2021 and 2019), and a curb defect reported in June 2023 that remains open. Other exterior maintenance matters have included a 2019 blocked sidewalk incident involving construction equipment and overgrown trees near communication lines. While these infrastructure issues are primarily related to external factors rather than the building itself, they may impact resident accessibility and outdoor areas. The property has also been subject to various street-level maintenance needs, including sign repairs, illegal postings, and holiday tree removal, all of which were addressed by the appropriate city departments.

Risk rating

How 1123 Stanyan St'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 526 buildings in this neighborhood, 268 are predicted to be safer.
