Initial analysis

The property at 3861-3865 23rd Street in Noe Valley is a two-story, three-unit multi-family residential building constructed in 1903, owned by William C. and Gayle Chan Trust. The building has undergone several significant maintenance and improvement projects over the past two decades, with the most recent major work being the installation of vinyl siding in 2016 (cost: $36,000) and earlier repairs to the rear of the building in 2013 (cost: $22,000) which included window replacements, dry rot repairs, and compliance updates. Historical maintenance work includes roof replacement in 2006 (cost: $11,000), structural footing revisions in 2003, and various porch repairs in 2009 affecting multiple units.

The building has faced several safety and maintenance challenges over the years, with notable fire safety issues in 2001 and 2007 requiring corrective actions including self-closing devices at exterior doors, fire proofing repairs, fire extinguisher maintenance, and combustible storage concerns. More recent issues include a rodent/insect infestation report in January 2024, and multiple incidents of parking violations and graffiti in 2024, though these latter issues do not directly impact building safety. The property's electrical system received attention with Ufer grounding installation in 2004. While there have been several building complaints and violations recorded, all have been marked as not active or resolved, with the latest routine apartment house inspection from 2007 showing various corrections were made. Two fire-related complaints were logged in 2009, one regarding blocked exits (deemed as having no merit) and another concerning combustible materials that was resolved in 2015.

Risk rating

How 3861-3865 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
29th percentile

Out of 1879 buildings in this neighborhood, 1334 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.

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.

12-Month severity forecast
No violation 59.3%
Moderate concern 25.4%
Severe concern 15.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
