Initial analysis

The two-unit residential building at 1711 9th Avenue in the Inner Sunset, owned by Tony Zheng and Man Lan Hu, was constructed in 1987 following the demolition of a single-family dwelling on the site. The property has undergone several significant maintenance and improvement projects since its construction, including termite repairs (1997), window replacements (1998), side wall residing (1998), and a roofing project (1998), though records show the roofing permit expired without completion. More recently, the building underwent a minor street space modification in 2015.

Recent incident records from 2023-2024 show multiple parking-related issues in the vicinity of the property, with at least four documented citations for illegal parking, including driveway blockages. Additional neighborhood incidents have included graffiti (October 2023), a fallen tree (June 2023), and several malfunctioning fire alarm system activations, though none resulted in actual fires or civilian injuries. The property's maintenance history suggests regular upkeep, with significant improvements made during its early years, though no major building permits have been recorded in recent years aside from the 2015 street space modification.

Risk rating

How 1711 9Th 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

Out of 1493 buildings in this neighborhood, 373 are predicted to be safer.
