Initial analysis

The two-unit residential building at 550-552 25th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1923, currently owned by the Eva Xu Hua Cai Revocable Trust. The property has undergone several significant renovations, with the most substantial work occurring in 2004 when a comprehensive $65,000 renovation included complete replacement of old plaster with new sheetrock and insulation, along with bathroom and kitchen remodels including new cabinets. This renovation was accompanied by electrical upgrades that installed 50 lights, 28 switches, 40 receptacles, and 25 circuits. Additional improvements from 2004 included installation of double-glazed windows on the first floor, replacement of wood siding, and conversion of street space. The building has seen consistent maintenance over the years, with earlier updates including bathroom repairs in 1998, reroofing in 1991, and bathroom tile work in 2010.

Recent activity at the property has primarily involved external issues rather than building safety concerns, with multiple reports of parking violations and street maintenance matters in the vicinity. In 2024, there were two reports of driveway blocking (both of which were invalidated due to incomplete complaint information), and one case of sidewalk parking that resulted in a citation. Previous neighborhood concerns included garbage issues in 2024 and 2021, a sidewalk defect in 2021, and illegal postings in 2020, all of which were resolved. Historical records indicate regular building maintenance has been performed, with no recent major structural or safety issues reported through the 311 system. The most recent building permit activity was a street space permit issued in 2017, though at a nominal cost of $1.00.

Risk rating

How 550-552 25Th 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.
