Initial analysis

The Wong Family Trust owns the two-story multi-family residential building at 4800 California Street in the Lake-Presidio neighborhood, which was constructed in 1905 and contains three residential units above a ground floor retail space. The property has undergone several notable commercial changes, most significantly transitioning from a laundromat to a grocery store in 2018-2019, with the grocery conversion receiving various permits including a Type 21 ABC license for limited alcohol sales. Building improvements during this period included ADA bathroom modifications, installation of new water heater, and electrical work. Earlier attempts to convert the commercial space to a nail salon and to make other interior improvements in 2017 were withdrawn.

The building's maintenance history shows regular upkeep, including a roofing project in 2017, though some past permits for street space (2017 and 2001) and an earlier roofing project from 1992 expired. Recent records from 2024-2025 show multiple street cleaning issues in the vicinity, including instances of garbage overflow, abandoned furniture, and debris requiring city intervention, though these external matters do not directly reflect on the building's condition. The property has received attention from various city departments regarding signage compliance, with one notable investigation in 2023 concerning unauthorized advertising signs covering windows and building surfaces.

Risk rating

How 4800 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.
