Initial analysis

The three-story multi-family residential building at 4727-4731 California Street, located in San Francisco's Inner Richmond neighborhood, is a 4-unit apartment building constructed in 1908 and currently owned by Fu Kwock & Yuet Sim Fung Ng. The property has undergone several significant maintenance projects over the years, including multiple reroofing efforts (most recently in 2008 costing $10,500), kitchen and bathroom remodeling in 1998, and correction of code violations in 1987. The building has been subject to regular housing inspections, with notable violations recorded in 2017 including fire escape ladder maintenance, water heater flue issues, and safety equipment requirements such as carbon monoxide detectors and fire extinguishers, all of which were abated by February 13, 2017. Earlier routine inspections in 2003 and 2009 also identified issues requiring attention, though all were resolved.

The building's maintenance history shows attention to basic infrastructure, with records of roof repairs and interior improvements, though some permits have expired without documentation of completion. Recent external maintenance issues noted through 311 calls include a streetlight repair in 2021, general street cleaning in 2020, and various neighborhood concerns such as illegal postings and graffiti in prior years. A noise complaint was filed in 2017 regarding amplified sound, and there was one report of an abandoned vehicle in 2014, though these are more reflective of neighborhood conditions rather than building-specific issues. The property's documented history shows regular engagement with housing inspection requirements and prompt response to identified violations, though the pattern of routine inspections suggests ongoing attention to building maintenance and safety compliance has been necessary.

Risk rating

How 4727-4731 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 1723 buildings in this neighborhood, 1292 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 67.6%
Moderate concern 19.7%
Severe concern 12.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
