Initial analysis

The two-unit residential building at 4138-4140 Fulton Street in the Central Richmond neighborhood, owned by Mei Judy Li Yun, is a 2-story flats and duplex structure built in 1923. The property has undergone significant renovations between 2015-2019, starting with substantial interior remodeling work in 2015-2016 that included kitchen reconfigurations, bathroom additions, and bedroom modifications in both units, along with electrical rewiring and plumbing system updates including new water service, water heater, gas pipe, and waste/vent systems. The electrical upgrade was particularly extensive, with one unit receiving 300-amp service with 3 meters and comprehensive rewiring of various rooms.

The renovation project faced delays and complications, as evidenced by multiple permit extensions and final inspection requests between 2018-2019, and at one point drew a building complaint in February 2018 regarding construction debris storage in the backyard, which was reported as a potential fire hazard and rodent attraction. Several permits from the 2015 renovation period expired without finalization, necessitating subsequent renewal permits in 2019 to obtain final inspections. While the major renovation work appears to have been completed, the property has experienced typical urban issues in the surrounding area, with multiple reports of illegal postings, graffiti, and one parking violation recorded between 2016-2020, though these were primarily external to the building itself and have been resolved according to city records.

Risk rating

How 4138-4140 Fulton 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 2250 buildings in this neighborhood, 1305 are predicted to be safer.
