Initial analysis

The three-story mixed-use building at 2550 San Bruno Avenue, owned by the Gao Family Trust, was constructed in 1908 and contains three residential units above a commercial space. The property has undergone several significant modifications over the past 30 years, with the most recent work completed in 2023 including the installation of new kitchen equipment and plumbing fixtures, valued at $45,000. A notable recent issue was reported in June 2023 when a generator was relocated from the roof to a second-floor apartment, generating noise complaints until it was removed in July 2023. The building has a history of accessibility improvements, including the installation of an ADA restroom in 2013 and multiple plumbing upgrades for water mains and waste systems between 2021-2023. Several major projects were proposed but either cancelled or withdrawn, including a 2019 remodeling plan that sought to add storage and new units, and a 1989 window replacement project.

The property's maintenance record shows attention to critical systems, with completed work on the fire system and windows in 1993 due to violations. Electrical upgrades were performed in 2003 with a change to underground service. The building has been subject to multiple 311 calls, primarily related to street cleaning issues and general maintenance concerns in the surrounding area between 2021-2024. Planning records indicate various proposals regarding unit configuration and parking requirements, with the most recent being an interior and exterior renovation project currently under review that includes adding new dwelling units. Two plumbing permits from 2021-2023 focused on infrastructure improvements, including water meter installations and waste pipe replacements, demonstrate ongoing maintenance of the building's essential systems.

Risk rating

How 2550 San Bruno 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.

Neighborhood percentile
