Initial analysis

The property at 1551 9th Avenue in San Francisco's Inner Sunset neighborhood is a 2-story, 4-unit multi-family residential building constructed in 1968, currently owned by the Michael J Bromberger Revocable Trust. The building has undergone several significant infrastructure improvements over the years, including a complete reroofing project in 2012 costing $12,500, window replacements in 2005 with energy-efficient models, and a major electrical upgrade in 2004 with a 400-amp service underground conversion. Notably, the building faced serious fire safety violations in October 2007 regarding combustible storage and missing directional signs, though these were resolved by December 2007.

Recent complaints and issues include a report of mold/mildew in the bedroom from 2014, and most recently, noise disturbances related to repair work and construction in March 2024. The property has experienced recurring sewer issues recently, with multiple sewage backup incidents reported in May 2024, suggesting potential ongoing plumbing challenges. The building's maintenance record shows regular upkeep, with three separate reroofing projects documented between 2000 and 2012. Recent external issues include multiple reports of vehicles blocking driveways and tree root damage causing walkway problems, though these are primarily affecting public infrastructure rather than the building itself. The most recent issues have been primarily related to external factors rather than structural or internal building problems, with most routine inspections and violations having been resolved promptly.

Risk rating

How 1551 9Th 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.
