Initial analysis

The 8-unit, 2-story multi-family residential building at 6112 California Street, owned by Dennis & Donna Wong, was constructed in 1960 in the Lake -- The Presidio neighborhood. The property has experienced several significant maintenance and safety issues over its history, most notably in July 2003 when multiple fire safety violations were documented, including problems with fire proofing, combustible storage, egress obstructions, fire extinguisher maintenance, central alarm system repairs, smoke enclosure door closers, fire escape ladder maintenance, and the need for a gas utility shutoff tool - all of which were abated by August 2003. In 2007-2008, there were serious concerns about the garage area including exposed leaking pipes, mold/mildew, inadequate lighting, and unsafe electrical cords, though these issues were eventually resolved. The building underwent some exterior maintenance in 2000, including stucco repairs and removal of stucco face, and in 2008 a gas water heater was properly raised to code compliance. A more recent issue arose in 2015 regarding lead-based paint concerns, which were addressed within a month.

Recent history shows ongoing maintenance and safety attention is required at this location, though most issues have been addressed promptly. The building's exterior has required various repairs and maintenance, including a street space permit in 2015 and a significant focus on weatherproofing and paint maintenance. Recent 311 calls from 2020 to 2024 have primarily concerned the surrounding area rather than the building itself, with reports of sidewalk cleaning needs, waste management issues, and shared space violations. While the building has had its share of challenges, the majority of documented violations and complaints have been resolved, though some recurring maintenance issues are evident in the property history.

Risk rating

How 6112 California St'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, 607 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

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.

12-Month severity forecast
No violation 40.2%
Moderate concern 47.7%
Severe concern 12.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
