Initial analysis

The property at 3777 23rd Street in Noe Valley is a two-unit, two-story multi-family residential building constructed in 1900, currently co-owned by George Landon Browning IV and another party. The building has undergone several significant improvements over the past two decades, including a comprehensive window and door replacement project in 2010 ($16,200), a kitchen remodel and second-floor modifications in 2010 ($15,000), and electrical system upgrades in 2011 that involved installing multiple service panels and circuits. More recent infrastructure work includes a sewer and house trap replacement in 2020, and there was a garage door widening project filed in 2016 to increase the opening from 7'-6" to 8'-4".

The property has experienced multiple 311 calls in recent years, with the most significant incident being a flooding issue reported in February 2022. While there have been several reports of abandoned vehicles and driveway blocking incidents in the vicinity (most of which were resolved when vehicles were gone upon inspection), these are primarily street-related issues rather than direct building concerns. A recent sidewalk defect was reported and resolved in January 2024, and there was some garage-related work that appears to be in conjunction with the earlier modification projects. The building's permit history suggests regular maintenance and updates to maintain and improve the property's systems and features, with no major safety or habitability issues recorded in recent years.

Risk rating

How 3777 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
69th percentile

Out of 1879 buildings in this neighborhood, 582 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.
