Initial analysis

The 5-unit, 2-story multi-family residential building at 144-148 Hermann Street in Hayes Valley, owned by Swingle David B Rev. Trust, has undergone several significant improvements and maintenance work since its construction in 1900. Most notably, recent 2024 upgrades include a comprehensive fire alarm system modernization completed in April 2024 to meet current safety codes, and an electrical system upgrade currently in progress to install a new 200-amp service with additional meters for all units. The building is also undergoing structural improvements with a permit filed in June 2024 to replace approximately 50 feet of brick retaining wall with a new reinforced concrete wall, though this work is primarily related to the adjacent property at 152 Hermann Street.

Historical records show consistent maintenance and upgrades, including multiple window replacements (2014 and 2002), a sewer line replacement in 2008, and electrical upgrades in previous years. The building's safety systems were notably addressed in 2001 when fire safety violations regarding extinguisher maintenance were corrected within two weeks of being cited. A mandatory soft story evaluation was conducted in February 2024. The property has been subject to regular housing inspections and permit approvals, including the legalization of a deck in 1993 and various routine inspections. Recent 311 calls primarily relate to external issues such as parking violations and graffiti in the surrounding area, rather than building-specific concerns.

Risk rating

How 144-148 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.
