Initial analysis

The three-unit multi-family residential building at 551-555 Diamond Street in Noe Valley was constructed in 1909 and features three stories. The property has undergone several significant renovations and maintenance work over the past two decades, including a substantial interior remodel and garage extension project permitted in 2001-2003, during which there were multiple complaints about possible unauthorized work beyond the scope of the permit. This project included the installation of new electrical systems comprising 40 lights, 20 switches, and multiple receptacles. In 2010, repairs were made to address dry rot in the exterior rear kitchen area at a cost of $10,000. The building's maintenance history shows regular upkeep, including a complete reroofing in 2003 costing $16,600.

Recent issues impacting the property include ongoing concerns about tree maintenance, with both damaged tree and property-damaging tree root reports filed in 2024. There have been multiple parking-related incidents near the property, including cases of driveway blocking and sidewalk parking between February and June 2023. The building's surroundings have experienced some regulatory challenges, as evidenced by a 2024 illegal postings complaint and ongoing tree maintenance issues, including tree basin backfilling needs reported in February 2023. The property has maintained compliance with building codes since the resolution of earlier permit-related complaints, though some recent maintenance issues suggest ongoing attention to the property's exterior infrastructure is needed.

Risk rating

How 551-555 Diamond 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 1879 buildings in this neighborhood, 1203 are predicted to be safer.
