Initial analysis

The property at 1345-1349 12th Avenue in San Francisco's Inner Sunset neighborhood is a two-story, three-unit multi-family residential building constructed in 1904, currently owned by the Jean Y Chin Revocable Trust. The building has undergone significant renovations and faced multiple violations over the years, with the most substantial work occurring between 2005-2007. Major improvements included complete rewiring of all three units, installation of fire sprinklers, roof framing repairs, foundation work, garage construction, and various unit remodels. These renovations followed serious building violations from 2005 citing deteriorated stairs, inadequate plumbing and electrical systems, and roof replacement needs. The property also had historical issues with lead paint notification in 2000, though this was abated by 2015.

Prior to the renovations, the building faced significant challenges, including a 2003 withdrawn demolition permit and multiple complaints about homelessness and disrepair in the mid-2000s. There were also concerns about construction work exceeding permitted scope in 2006, particularly regarding a rear cottage and roof modifications. Since 2020, the building's issues have primarily been related to parking, with numerous complaints about driveway blocking between 2022-2024, though these are external to the building's condition. A notable recent incident involved a Christmas tree removal in January 2024, which was promptly addressed. The property's extensive renovation history suggests a substantial investment in improving building systems and infrastructure, though it should be noted that some work occurred under previously issued citations for various building deficiencies.

Risk rating

How 1345-1349 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

Out of 1493 buildings in this neighborhood, 1075 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 59.7%
Moderate concern 27.9%
Severe concern 12.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
