Initial analysis

This two-story, four-unit multi-family residential building located at 5233-5239 California Street in the Central Richmond neighborhood was built in 1922 and is currently owned by Ng Family Trust. The property has undergone several significant improvements, with the most recent major work occurring in September 2024, including kitchen renovations with new countertops, sink, hood, electrical upgrades, and the installation of a 50-amp subpanel ($28,000). A critical infrastructure upgrade was completed in October 2022 with the replacement of a 4-inch sewer lateral and new house trap installation at the property line. The building has a documented history of maintenance and improvements, including termite and dry rot repairs in 1993, kitchen remodeling in 1989, and a code compliance update in 1987.

In June 2009, the property underwent a routine inspection that identified multiple fire safety violations, including issues with fire extinguishers, combustible storage, and egress obstructions. However, these violations were all promptly addressed and abated by July 2009. More recent maintenance records show regular upkeep, including a complete reroofing project from 2004 (permit expired) and various electrical and plumbing upgrades. The building's recent permit activity and maintenance history suggest ongoing investment in property improvements and code compliance. While there have been several 311 calls regarding street and sidewalk maintenance near the property between 2020 and 2024, these were primarily related to public infrastructure rather than individual building issues, including concerns about street lighting, graffiti, and parking enforcement matters.

Risk rating

How 5233-5239 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.

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.

Building size

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

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 64.9%
Moderate concern 24.2%
Severe concern 10.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
