Initial analysis

134 Duboce Avenue is a three-story, 15-unit multi-family residential building constructed in 1908, currently owned by Mark E & Sophia S Cusing Re. The building has undergone several significant safety upgrades in recent years, including a major fire alarm system upgrade completed in November 2023 with a cost of $36,480 to comply with current fire code requirements, and historic soft-story retrofit work completed in 2016 that included foundation improvements. The building has experienced recurring fire safety issues, with multiple fire-related complaints and violations between 2022 and 2024, including concerns with fire escape functionality, extinguisher maintenance, and system upgrades. A notable cluster of violations was documented in December 2022 regarding fire safety equipment and documentation, though these were officially abated by May 2023. Additional historical improvements include window replacements in 2003, roofing work in 2017, and various structural repairs dating back to the 1980s.

The building's maintenance history shows attention to basic infrastructure needs, though not without periodic issues. An inspection in 2000 revealed multiple concerns including non-compliant kitchen plumbing and fire safety features. Recent 311 calls (eight instances between August and November 2024) indicate ongoing concerns with abandoned furniture and debris near the property, while the most recent fire complaint regarding extinguishers was resolved in November 2024. Statistical data from fire incidents suggests most activations are either false alarms or related to cooking incidents, with no recorded civilian injuries. The building's fire safety systems have undergone regular updates, as evidenced by the recent fire alarm system modification and compliance work completed in 2023, though periodic violations indicate challenges in maintaining consistent compliance with safety regulations. The property is categorized as Tier 2 for soft-story compliance, with work officially completed and a CFC issued.

Risk rating

How 134 Duboce Ave'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.
