Initial analysis

The two-story, four-unit apartment building at 719 6th Avenue in San Francisco's Inner Richmond neighborhood was constructed in 1923 and is currently owned by Dou Zhixin. The property has undergone several significant renovations and faced various compliance issues over the past two decades. Most notably, in 2016, substantial improvements were made including the construction of two new bathrooms, electrical service upgrade to 200A, and installation of new smoke detectors, totaling approximately $80,000. Earlier improvements included multiple window installations in 2007 and 2010, and reroofing work in 2013. The building experienced notable violations in 2001 related to lead paint hazards, smoke detector requirements, and egress obstructions, though these were all abated by September 2001. A significant complaint in 2015-2016 reported issues with broken windows, debris, hoarding, and pest presence, which was subsequently resolved. Recent maintenance activity includes regular responses to parking violations (with multiple citations issued between 2018-2024) and general street cleaning efforts, though these are external to the building itself. The property has maintained its four-unit configuration, with recent planning records noting no exterior changes to the front and confirming access to required open space for all units.

Risk rating

How 719 6Th 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.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 62.3%
Moderate concern 18.3%
Severe concern 19.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
