Initial analysis

The two-unit, two-story residential building at 1129 Broderick St, built in 1904 in the Anza Vista neighborhood, has undergone several significant improvements and faced some challenges over its history. The most recent major work was completed between late 2020 and early 2021, involving a comprehensive bathroom remodel with plumbing relocation and electrical updates. The building has received attention to its basic infrastructure, including a sewer line replacement in 2007 and window upgrades in 2006, when nine wood windows were replaced with Marvin dual-pane units and the heating system was upgraded for improved efficiency. The property has seen some concerning issues in the past, including a 2014 complaint regarding missing fire and carbon monoxide detectors, burn marks near hot water pipes, and a clogged chimney, though these problems were abated within a week of being reported. There is also a history of sewer-related issues, with two sewage backup incidents reported in 2016, and the building's exterior has had various maintenance work done, including proposed deck construction in 1992 and horizontal addition in 1988, though these permits ultimately expired.

The property management has demonstrated investment in maintaining and upgrading the building's systems, as evidenced by the recent bathroom remodel and earlier infrastructure improvements. Recent exterior maintenance issues have been minimal since the 2020 renovations, with only periodic concerns like overgrown trees (2023) and occasional street cleaning needs being reported. The building's location has experienced typical urban challenges such as sidewalk cleaning requirements and some garbage issues between 2010 and 2022, though these are neighborhood-wide concerns rather than building-specific problems. The property is currently under the ownership of the Cho Hi Sun Family Trust, which has maintained the building through various improvements and repairs over the years.

Risk rating

How 1129 Broderick 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.
