Initial analysis

The three-unit multi-family residential building at 3955-3957 24th Street in Noe Valley, owned by the Owyang Shirley Trust, has a documented history spanning from its 1926 construction to the present day. The property has recently undergone accessibility improvements, with an automatic door opener installation in September 2023 to comply with the accessible entrance program. Significant structural work was performed in 2004, including underpinning for shoring during adjacent construction and concrete leveling of existing slabs. More recent infrastructure maintenance includes a sewer replacement completed in 2014. The building has experienced multiple false alarms and system activations over the years, including smoke detector, CO detector, and alarm system malfunctions, though none resulted in injuries or actual fires.

The property and surrounding area have faced various maintenance and infrastructure challenges in recent years, particularly during 2024, with multiple reports of pavement defects, flooding issues, and garbage/debris concerns being addressed by city services. There was one plumbing incident in late 2024 involving a 4-inch vent cleaning. The building's fire safety systems have required periodic attention due to false alarms, with the most recent being an unintentional alarm activation. The property is currently facing an open noise complaint from January 2025, and there are several property maintenance issues being addressed, including bench placement and potential sidewalk damage. While the building's systems have experienced some recurring issues, particularly with alarms and system activations, there have been no recorded injuries or major incidents requiring emergency response.

Risk rating

How 3955-3957 24Th 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
47th percentile

Out of 1879 buildings in this neighborhood, 996 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.

Neighborhood location

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

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

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 67.4%
Moderate concern 24.7%
Severe concern 7.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
