Initial analysis

The Loi Family Trust owns this two-unit, two-story multi-family residential building located at 5631 California Street in San Francisco's Central Richmond neighborhood. Built in 1915 and classified as a Flats & Duplex structure, this property has experienced several notable incidents over the past decade. The most serious concern was a carbon monoxide detector activation in early 2020, though no carbon monoxide was detected and there were no civilian injuries reported. Prior to that, the building had a false alarm activation of an alarm system in 2019. The property's maintenance history includes multiple reports of illegal postings in mid-2020, which were resolved, and a more significant 2016 incident involving sidewalk infrastructure problems, where approximately 100 square feet of damaged/uneven sidewalk and 9 linear feet of unpermitted driveway were documented. Earlier issues included a 2015 streetscape cleaning matter involving loose garbage, and a report of an abandoned vehicle in 2010 that was resolved when the vehicle was no longer present at the location. The only building permit on record is a street space permit from 2011 with a nominal cost of $1.00.

The building's incident history shows periodic maintenance and safety checks, though concerns about various urban infrastructure elements such as sidewalks, street cleaning, and illegal postings have arisen over the years. The most recent safety-related incidents were the detector activations in 2019-2020, while earlier structural issues were primarily related to exterior elements like sidewalks and street conditions.

Risk rating

How 5631 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
68th percentile

Out of 2250 buildings in this neighborhood, 720 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

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 80.7%
Moderate concern 16.6%
Severe concern 2.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
