Initial analysis

The property at 126-128 Hugo Street is a two-unit, two-story multi-family residential building located in San Francisco's Inner Sunset neighborhood, built in 1908 and currently owned by Rose Koe-jui Wang. The building has undergone significant changes and improvements over the past several years, particularly between 2017-2023, including the legalization of an unauthorized basement unit (Unit 126A) in 2019 that required multiple permits and cost $137,396 to bring into compliance. This work was necessary to address multiple building violations from 2017, including issues with unauthorized unit construction, inadequate fire safety features, and egress violations. The property has seen substantial safety upgrades, including comprehensive fire sprinkler system installations in 2019 ($16,000), a new sprinkler monitoring system in 2023 ($8,656), and electrical upgrades including a 200-amp underground service panel installation in 2022.

The building's history shows a progression from serious safety concerns in 2017, when multiple fire safety violations were documented, to improved compliance through substantial renovations and safety system upgrades. Earlier issues included problematic conditions in the basement unit, with tenant complaints about mold, inadequate heat, and plumbing leaks. The property has maintained regular upkeep of essential systems, including roofing work in 2017 and various plumbing updates, with more recent maintenance showing a focus on fire safety improvements. While the building faced multiple fire alarm system malfunctions between 2017-2023, these appear to be technical issues rather than actual fire incidents, as no civilian injuries were reported in connection with these alarms. The most recent building improvements focus on maintaining up-to-date fire safety standards and addressing previous code violations, suggesting ongoing attention to building safety and compliance requirements.

Risk rating

How 126-128 Hugo 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
94th percentile

Out of 1493 buildings in this neighborhood, 90 are predicted to be safer.

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

12-Month severity forecast
