Initial analysis

The 1921 Taraval Street property is a two-story, four-unit multi-family residential building constructed in 1951, currently owned by the Siu Hing Yuen Lo 2016 Trust. The building has undergone several significant infrastructure upgrades over the years, with the most recent being a completed re-roofing project in November 2023 costing $17,700, and a sewer replacement completed in September 2020. Historical records show earlier maintenance work including a re-roofing project in 1992, termite repairs in 1992, and a fire safety compliance upgrade in 1985. The electrical system received a major upgrade in 2005 with a 200-amp underground conversion.

The building has experienced multiple fire safety-related violations, most notably in 2000-2003, including issues with fire extinguisher maintenance, smoke detector functionality, and fire escape ladder condition, though these violations were all eventually abated. A work without permit complaint was filed in 2018 but was marked as not active. Of particular concern is an active complaint from May 2024 regarding an unoccupied illegal unit that remains unresolved. The property has also experienced recurring issues with parking enforcement, with multiple complaints about vehicles blocking driveways and parking on sidewalks between 2016 and 2023, though these are external to the building itself and primarily affect street access. A pavement defect was reported and resolved in 2016. Regular housing inspections have been conducted, with all previous violations being addressed, though the current status of the illegal unit complaint warrants attention.

Risk rating

How 1921 Taraval 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
