Initial analysis

The two-unit residential building at 3356 23rd Street in the Inner Mission is a two-story flats and duplex structure that dates back to 1900, currently owned by William N & Rosemary Farac. The building's maintenance history shows relatively minimal major work, with only two significant permit records: a completed reroofing project from 1996 and most recently, an electrical upgrade to remove knob and tube wiring that was issued in January 2025, indicating the owners' efforts to modernize the building infrastructure.

The property has experienced several external maintenance issues over the years, particularly in 2014-2019, when multiple general cleaning cases were documented, primarily involving loose garbage on the street and sidewalk areas. While these cleaning issues were resolved, they suggest some ongoing concerns about exterior maintenance. More recently, in 2015, there was a sidewalk defect reported due to tree root lifting, which required response from multiple departments and appears to have been addressed. The most recent incidents in 2023 were limited to minor public infrastructure issues (graffiti on a parking meter and a defaced sign), which were promptly resolved. The building's maintenance record shows regular upkeep of major systems (with the recent electrical upgrade being particularly noteworthy), though the historical pattern of street cleaning complaints suggests that some attention to external areas may have been needed in the past.

Risk rating

How 3356 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

Out of 2380 buildings in this neighborhood, 452 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

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 79.9%
Moderate concern 12.6%
Severe concern 7.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
