Initial analysis

The 8-unit, 2-story multi-family residential building at 4321 Judah Street in the Outer Sunset, owned by the Maurice Hoory 2001 Trust, has undergone several significant improvements since its construction in 1957. Most notably, the building completed a mandatory soft-story retrofit in 2016 (with a cost of $84,000) to enhance seismic safety, achieving a completed status with CFC issuance. The building has a documented history of addressing maintenance and safety concerns, including a comprehensive fire safety inspection in September 2016 that identified multiple issues requiring correction, such as repairs to fire proofing, smoke enclosure doors, window latches, and verification of fire escape drop ladder operation, all of which were abated by June 2017. Previous maintenance work includes reroofing projects in 1999 (expired permit) and 2011 ($16,700), pest damage repairs in 1989, and electrical improvements including the installation of a ufer ground in 2017 (expired permit).

Several housing inspections over the years have revealed various maintenance issues, including a 2014 complaint about water damage and appliance problems in unit #6. The building's most recent history shows some external maintenance challenges as documented in 311 calls, with recent reports in 2024 noting issues with debris and waste management near the property. The property has demonstrated responsiveness to regulatory requirements, as evidenced by the completion of the soft-story retrofit and the resolution of multiple building violations. While the building has experienced various maintenance issues over the years, records indicate that these have generally been addressed through proper channels, with the most substantial improvements focusing on seismic safety and fire safety compliance.

Risk rating

How 4321 Judah 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 632 buildings in this neighborhood, 607 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

12-Month severity forecast
No violation 15.2%
Moderate concern 41.5%
Severe concern 43.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
