Initial analysis

The 65-unit, 6-story multi-family residential building at 1-15 Hermann Street in Hayes Valley has experienced several significant maintenance and safety issues in recent years. Most notably, there have been recurring heating system problems, with multiple complaints about lack of heat throughout the building in late 2023 and early 2024, including one instance where heat was reportedly lost building-wide for 14 days. More recently, there are active complaints from September 2024 concerning hazardous wiring and incomplete service upgrades following multiple unit remodels. The building's heating systems have undergone multiple upgrades, including a steam boiler replacement in 2021 and a new boiler installation in 2024 (completed in March 2024).

The property has seen substantial renovation activity since 2019, including extensive plumbing work in multiple units, a fire alarm system upgrade in 2020, and various accessibility improvements. However, there have also been concerning incidents involving water damage and potential mold growth, with complaints about moisture issues and even mushroom growth in 2021, though these issues were eventually abated. The building has experienced several fire safety-related violations, including a recent sleeping area requirement violation issued in November 2023, though past violations (including those for the alarm system, exits, and electrical systems) have generally been corrected promptly. The property has undergone significant commercial adaptation as well, with the conversion of a former laundromat space to a restaurant with associated improvements between 2020 and 2023.

Risk rating

How 1-15 Hermann 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.
