Initial analysis

The property at 4331-4333 Balboa Street, located in San Francisco's Outer Richmond neighborhood, is a single-story multi-family residential building constructed in 1924 containing two units. Most notably, in January 2023, a significant structural issue was identified when approximately 5 lineal feet of foundation at the west side of the building was found to be undermined, creating potential safety concerns regarding structural integrity, though this violation was abated by May 2023. The building has undergone several maintenance projects over the years, including a $6,000 reroofing project in 2006 and back stairs repairs in 1987. A complaint regarding unauthorized construction work was filed in June 2010 but was resolved within two days.

The property has been the subject of multiple reports regarding abandoned vehicles in the vicinity between 2015 and 2017, with several cases being documented through the DPT Abandoned Vehicles Work Queue, though these were unrelated to the building's condition. A "Request for Rebuild Letter" was issued and closed in July 2022 under the name of owner Darryl Sapien, though the specific nature of this request is not detailed in the records. The building's permit history shows regular maintenance activities, with no outstanding violations or permits as of the latest available data through October 2023.

Risk rating

How 4331-4333 Balboa 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

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.
