Initial analysis

The property at 2434 California Street is a mixed-use, two-unit residential building located in San Francisco's Pacific Heights neighborhood, owned by the Dominic Maionchi Revocable Trust. Built in 1908, this flat & store building consists of one residential unit and 1,200 square feet of commercial space. The building has undergone several significant renovations, with the most recent being a $20,000 remodel of Unit 2 in 2019 that included updates to a kitchen and bathroom while maintaining fire-rated separation between the units and business area. The commercial space has experienced various transformations, including a conversion from a fitness center to a hair salon in 2010, which was completed with substantial updates to electrical, plumbing, and infrastructure systems.

The building's history includes some concerning safety issues, particularly in 2003-2004 when there were serious foundation concerns due to excavation work, though these were eventually resolved. Several graffiti incidents were reported between 2021-2023, mainly affecting the commercial portion of the building, along with multiple reports of waste on nearby sidewalks in early 2021. In late 2024, there was a report of garbage and debris that was subsequently addressed. The building's systems have been regularly maintained and updated, with the most recent significant works including the 2019 unit remodeling and historical improvements to electrical systems, including a comprehensive upgrade in 2003 that installed extensive new electrical infrastructure throughout the mixed-use building. All building permits related to the property are appropriately documented, showing a pattern of regular maintenance and upgrades to both residential and commercial areas of the building.

Risk rating

How 2434 California 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.

Neighborhood percentile

Out of 963 buildings in this neighborhood, 260 are predicted to be safer.
