Initial analysis

The property at 330 10th Avenue is a two-story, four-unit multi-family residential building constructed in 1974, currently owned by Guan Yao Zhen. The building has undergone several significant maintenance events, including two reroofing projects (one in 1991 and a more recent one in 2012 costing $5,000), and major repairs in 1985 following fire damage that required replacement of siding, windows, sheetrock, and doors. The building has a documented history of multiple housing inspections and violations, with the most recent routine inspection in December 2016 revealing several safety concerns that were subsequently addressed by December 27, 2016. These violations included the need for a gas utility shutoff tool, gas meter instructional diagram, carbon monoxide detectors, and various maintenance issues. An earlier inspection in 2003 identified problems with an inoperable kitchen window, bathroom mold, and aging carpeting. The property has also experienced recurring maintenance issues, as evidenced by multiple complaints from 1998 through 2003 regarding window functionality, heating problems, and appliance concerns.

Recent activity at the property has primarily consisted of parking enforcement issues, with multiple documented cases of driveway blocking violations between 2022 and 2024, resulting in several citations being issued. The building's recent maintenance history appears less active, with no major building permits or violations recorded in the past seven years. Street cleaning and waste management issues were reported in 2022, including an overflowing city garbage can and loose yard waste on the sidewalk. While the building has experienced various maintenance and safety compliance challenges in the past, the most recent documented violations were promptly addressed within the inspection period.

Risk rating

How 330 10Th 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 1723 buildings in this neighborhood, 362 are predicted to be safer.

Model explanation

What's driving this score

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

Moderate concern 13.0%
Severe concern 8.3%
