Initial analysis

The three-story, two-unit multi-family residential building at 10 Balmy Street in the Inner Mission has a long history dating back to 1900, with significant recent issues regarding tenant comfort and building compliance. Most notably, in late 2023, the property faced multiple heat-related violations when complaints were filed about inadequate heating systems, with specific allegations that the landlord had neglected maintenance and communication with tenants. These violations were addressed through the legal process, with director hearings scheduled in January 2024. Another major incident occurred in 2012 when an unauthorized vertical addition was constructed, leading to a 2013 permit for removal of illegal roof additions and restoration of the original building envelope. The building's maintenance history includes several completed projects, such as a 1995 reroofing and a 1984 rear porch repair following fire damage.

The property has experienced recurring issues with exterior cleanliness in the surrounding area, as documented in multiple 311 calls between 2019 and 2022, primarily related to loose garbage and waste removal needs. These calls, though not directly related to the building's internal conditions, indicate some ongoing challenges with the property's immediate surroundings. While the building's structure has undergone various permitted improvements over the years, recent heating system violations and the handled roof modification issue suggest occasional lapses in maintaining required building standards, though many historical improvements indicate previous attention to building maintenance.

Risk rating

How 10 Balmy 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.
