Initial analysis

The property at 1301 Judah Street in San Francisco's Inner Sunset neighborhood is a two-story, four-unit multi-family residential building constructed in 1958, currently owned by John P & Marylouise T Serra. The building has undergone some significant maintenance work, most notably a complete reroofing project in 2009 costing approximately $13,480. During a routine housing inspection in October 2000, several safety violations were identified and subsequently addressed within four days, including issues with fire extinguisher maintenance, gas utility shutoff tools, smoke detector placement, egress obstructions, and gas meter instructional diagrams. The building has been subject to three routine housing inspections (2000, 2002, and most recently in 2023), all of which have been marked as not active.

In recent years, the building's immediate vicinity has experienced various street-related issues, with multiple 311 calls regarding garbage and debris (including furniture and mattresses) between 2022 and 2024, and several parking enforcement actions for vehicles blocking driveways and parking on sidewalks. The most recent street cleaning issues were reported in November 2024, while a pavement defect was noted and resolved in January 2023. Notably, there has been one documented fire service call to the address, though no civilian injuries were reported and the nature of the call was classified as "Service Call, other." While the building has experienced some maintenance and safety compliance issues in the past, particularly in 2000, all identified violations were promptly resolved, and there have been no recent patterns of similar violations or safety concerns.

Risk rating

How 1301 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.
