Initial analysis

The 3-story, 6-unit multi-family residential building at 4430-4432 California Street, constructed in 1924 and owned by Doris Wong, has undergone several significant renovations and faced multiple regulatory challenges over the past decade. The most recent major work occurred in 2011, when extensive renovations were completed on the 2nd floor rear unit, including kitchen relocation, bathroom remodeling, and electrical improvements totaling over $52,000. This renovation was part of a series of correctional measures addressing violations from 2010, which included removing illegal windows along property lines, addressing fire safety concerns, and compliance with building codes. The building has experienced periodic routine inspections since 2000, with several violations noted and subsequently resolved, including issues with backflow prevention, fire safety systems, and unauthorized modifications.

More recent concerns have been relatively minor and generally external to the building itself, with 311 reports showing typical urban maintenance issues such as street cleaning, garbage, and graffiti complaints between 2019 and 2025. There was one fire-related incident involving a malfunctioning alarm system, but no injuries were reported. The property has undergone multiple unit renovations over the years, including window replacements in 2009 and various kitchen and bathroom remodels, with proper permits obtained in recent projects including plumbing and electrical work. While there have been several building code violations and complaints, records indicate that these issues have typically been addressed and resolved through appropriate permits and corrections.

Risk rating

How 4430-4432 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, 541 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.

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 64.8%
Moderate concern 20.9%
Severe concern 14.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
