Initial analysis

The three-story, multi-family residential building at 6143-6145 California Street in the Central Richmond neighborhood is a duplex property built in 1913, currently owned by Du Yi Feng. The building has undergone several significant renovations over the past decades, with the most recent work being a window replacement project in 2022 costing approximately $4,066. A notable series of improvements took place in 2012, including the removal of an illegal sunroom and deck from the second and third floors, installation of a new means of egress stairway, addition of a half bathroom, and conversion of a storage room into a sunroom on the first floor, along with necessary structural repairs. This work followed two complaints in 2012 regarding unsafe construction and excavation work on the ground floor, which were eventually abated by February 2013. The property has seen various other improvements, including a complete bathroom addition on the third floor in 2016, reroofing in 1997, and installation of aluminum windows in 1988.

Recent activity at the property has been largely routine, with the majority of recent 311 calls (2023-2024) related to street maintenance and parking issues in the vicinity rather than building-specific concerns. While there were multiple reports of garbage and debris on the street in 2024, these were general neighborhood issues rather than building-specific problems. The building's permit record shows consistent maintenance and upgrading of facilities over the years, with no active violations or unresolved complaints regarding the building's condition or safety as of the latest available data. The property's documented history suggests regular upkeep and attention to building code compliance, particularly following the 2012 incidents that led to various structural improvements and compliance measures.

Risk rating

How 6143-6145 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
72th percentile

Out of 2250 buildings in this neighborhood, 630 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.

Neighborhood location

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

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 72.2%
Moderate concern 24.4%
Severe concern 3.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
