Initial analysis

The two-unit residential building at 3942 23rd Street in Noe Valley, owned by Gerald Allen Posey, is a two-story flats and duplex structure built in 1900. The property's maintenance history shows several significant structural repairs in the 1990s, including three consecutive permits in 1995 for addressing dry rot issues and garage repairs, a reroofing project in 1998, and a more recent sidewalk defect issue reported in 2020 that remains open as of October 2023. The building's surroundings have experienced various municipal service calls, with the most pressing recent issue being an ongoing sidewalk defect from May 2020. The property has also faced some infrastructure challenges, including sewer issues in early 2021 that were resolved and a tree-related incident in March 2020 involving a fallen limb that was inspected and pruned by city crews.

The area around 3942 23rd Street has experienced periodic street maintenance needs, with multiple reports of loose garbage requiring general cleaning in 2022 and 2023. Two instances of encampment-related debris removal requests were made in October 2022, though no waste was found upon inspection. The property has been subject to minor administrative issues such as illegal postings in 2017, both of which were resolved. The historical permit record indicates attention to structural maintenance in the past, particularly regarding moisture-related issues, though all listed permits from the 1980s and 1990s are now expired.

Risk rating

How 3942 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
63th percentile

Out of 1879 buildings in this neighborhood, 695 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 age

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 85.5%
Moderate concern 9.8%
Severe concern 4.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
