Initial analysis

The two-story multi-family residential building at 111 12th Ave, owned by the Ling Family 2004 Trust, is a 1905 flats and duplex structure located in The Presidio - Lake neighborhood. The property's maintenance history shows several significant repairs, with the most recent being a damaged property report filed in February 2024. Notable building improvements include a $4,000 repair to rear stairs in 2011 and a complete sewer line replacement in 2008. Historical records show earlier maintenance work such as re-roofing in 2000 (permit expired) and various sidewalk-related permits in 2007-2008.

The building has experienced recurring issues with graffiti, particularly between 2021-2022, though most incidents were resolved promptly. There was one reported case of damaged property in early 2024 that was transferred for further handling. Other recent concerns include illegal postings (2021-2022), general cleaning issues (2022), and one documented instance of driveway obstruction requiring parking enforcement (2021). While these external maintenance and enforcement issues have been consistently addressed, it's worth noting that most incidents have been promptly resolved through appropriate channels. A traffic engineering complaint related to the area was transferred to the MTA's Slow Streets Project section in late 2020.

Risk rating

How 111 12Th 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
52th percentile

Out of 660 buildings in this neighborhood, 317 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.

Building age

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 80.3%
Moderate concern 15.6%
Severe concern 4.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
