Initial analysis

The three-unit multi-family residential building at 4042-4046 California Street, located in the Lake-Presidio neighborhood, is a three-story flats and duplex structure built in 1906 and currently owned by Wayne Dorais Bypass Trust. The property has undergone several significant maintenance and repair projects over the years, with the most substantial being a complete roof replacement in 2002 costing $19,500, and a sewer repair in 2009. A notable cluster of building violations was documented in April 2002, including issues with fire safety (missing fire extinguishers and obstructed egress), security concerns (missing proper door hardware and self-closing devices), and building maintenance problems (lead paint hazards and various repair needs), though all these violations were abated by June 2002. The history includes some serious maintenance issues, with a 2002 complaint reporting problems such as a failing ceiling over the stairwell, leaking ceilings, dry rot in the exterior wall, and plumbing issues, though these were addressed. More recent inspections included a routine check in 2004 and a report of blocked fire exit stairs in 2003.

Recent history shows fewer building-specific issues, with the most recent 311 calls primarily relating to street and sidewalk matters rather than building conditions, including reports of illegal postings (2022), defaced street signs (2021), and sidewalk defects (2012). The building has maintained compliance with housing inspections since the 2002 violations were resolved, though the clustered nature of those violations suggests there was a period requiring significant attention to various safety and maintenance issues. The property continues to be classified as a multi-family residential building under city records.

Risk rating

How 4042-4046 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, 429 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 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.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 66.8%
Moderate concern 20.2%
Severe concern 12.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
