Initial analysis

The property at 3850-3854 23rd Street in Noe Valley is a three-story, multi-family residential building constructed in 1900, currently containing three residential units plus a commercial space, and owned by Henry Klein. The building has undergone several significant renovations and maintenance projects over its history, including a complete reroofing in 1998, kitchen and bathroom renovations in 1991-1992, and various street space permits issued in 2009 and 2017 for sidewalk-related work. A notable planning application is currently submitted for converting an existing commercial unit to residential use, which would involve expanding the garage space for additional bicycle parking and addressing variance requirements for indirect access to shared outdoor space.

The property has experienced some maintenance and service issues in recent years, with multiple instances of parking-related complaints, including two cases of driveway blocking in 2022 and 2024, though these were resolved through enforcement actions. Other service calls have primarily involved routine street maintenance matters, such as garbage collection and sidewalk cleaning. The building's infrastructure has received regular attention, as evidenced by the various permits for improvements and repairs, though there are some expired permits from the 1990s related to flooring demolition and cabinet replacement. The property's documented history shows consistent efforts to maintain and improve the building, with the most recent planning activity suggesting a proactive approach to maximizing the property's residential potential.

Risk rating

How 3850-3854 23Rd 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
35th percentile

Out of 1879 buildings in this neighborhood, 1221 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.

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.

Neighborhood location

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

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 49.8%
Moderate concern 22.0%
Severe concern 28.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
