Initial analysis

The two-story, four-unit apartment building at 116 19th Avenue in the Lake-Presidio neighborhood, owned by Quinto Shang Pen, has undergone several maintenance and safety compliance updates since its construction in 1970. The building's maintenance history includes two roofing projects: a completed re-roofing in 2015 costing $11,200, and an earlier expired permit for re-roofing work from 1992. In 2012, a furnace replacement was undertaken, though the permit for this work is listed as expired.

The building's safety compliance history includes a significant cluster of violations identified during a routine inspection in October 2002, which were all promptly addressed and abated within five days. These violations involved gas utility safety requirements, including the need for a gas shutoff tool and the posting of an instructional diagram, as well as smoke detector installation requirements in the lobby area. A subsequent routine inspection was conducted in April 2008, which was completed within the same month, though no violations were recorded from this inspection. All known violations have been resolved, and there are no active complaints or violations on record as of October 2023, indicating that the property has maintained compliance with safety requirements since the resolution of the 2002 violations.

Risk rating

How 116 19Th 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 660 buildings in this neighborhood, 231 are predicted to be safer.

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.

Owner's portfolio size

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

12-Month severity forecast
No violation 74.0%
Moderate concern 15.0%
Severe concern 11.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
