Initial analysis

The property at 118 12th Avenue is a 2-story, 4-unit multi-family residential building located in the Lake-Presidio neighborhood, owned by the Woo Family Trust-trust B and constructed in 1974. The building's maintenance records show periodic attention to basic infrastructure, including two roof replacements: one completed in 1993 and another permitted in 2019 at a cost of $9,000. Significant fire safety violations were documented in July 2004, involving issues with fire proofing materials and fire extinguisher maintenance, though these violations were promptly addressed by August 12, 2004. The building has undergone regular routine housing inspections in 1999, 2004, and 2008, with one notable plumbing issue reported in 1997 regarding leaks from pipes affecting the basement/garage ceiling and moldy carpet, which was resolved within three days.

The property has experienced recurring parking-related issues, with multiple complaints between 2020 and 2024 regarding driveway blocking, resulting in several citations. Recent exterior maintenance concerns include tree maintenance issues in 2020, where an empty tree basin was identified as a trip hazard and required backfilling/adjustment, which was completed by December 2020. The building's location has also required occasional street cleaning services, with reports of loose garbage in 2012 and a medical waste incident in 2010, both of which were resolved. While the building has had its share of maintenance issues over the years, most problems have been addressed relatively swiftly, with no active violations on record as of now.

Risk rating

How 118 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
86th percentile

Out of 660 buildings in this neighborhood, 92 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.

Neighborhood location

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

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 72.9%
Moderate concern 17.1%
Severe concern 10.1%
