Initial analysis

The three-story, multi-family residential building at 246-260 Judah Street in San Francisco's Inner Sunset neighborhood, owned by Leslie Lum, was constructed in 1912 and contains 5 units plus commercial space. The property has undergone significant recent improvements, including a comprehensive $140,000 remodeling of units #1 and #3 in late 2023, followed by window replacements and HVAC system upgrades in 2024. Of particular note is the recent fire safety upgrade completed in September 2024, which involved enhancing the fire alarm system to comply with current standards, including the addition of radio connections and low-frequency sounders. The building has experienced several maintenance and safety issues over the past few years, including multiple complaints and violations in 2019 regarding lead paint hazards, carbon monoxide and smoke alarm deficiencies, and access to common areas, though these were all abated by June 2019. More recent tenant complaints from 2024 have included concerns about window functionality, water quality, and dust during construction work, suggesting potential ongoing maintenance challenges. The property has an active telecommunications component, with multiple permits and modifications for T-Mobile/Sprint equipment between 2015 and 2024, including antenna installations and equipment upgrades. Three electrical permits related to new installations were filed in September 2024, and substantial plumbing work was completed earlier in 2024.

The building's history shows a pattern of regular maintenance and upgrades, though sometimes reactive to tenant complaints. Past issues have included problems with paint condition (2019), window functionality (2024), and concerns about construction impact on residents (2024). Multiple permits related to the fire safety system, accessibility improvements, and telecommunications equipment maintenance suggest ongoing attention to both resident safety and modern infrastructure requirements. The property has had various routine inspections and some compliance issues in the past, most of which have been resolved, indicating generally responsive management though with occasional maintenance challenges. Recent permit activity suggests active investment in improving building systems and living conditions, particularly in units #1 and #3.

Risk rating

How 246-260 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.
