Initial analysis

The property at 662-666 Green Street in San Francisco's North Beach neighborhood is a three-story, six-unit multi-family residential building constructed in 1913. The building has undergone several significant renovations and repairs, most notably following a fire incident in September 2009 that required extensive repairs costing $280,000, including wall reconstruction, floor joist replacement, new roofing, and window replacements. In 2010, substantial work was completed including rear building reconstruction, reframing of bathrooms and kitchens in all units, and window replacements. More recent maintenance includes a reroofing project in 2022 ($15,750), and in 2023, repairs were completed to address multiple violations including rear staircase repair, window repairs, and the installation of smoke and carbon monoxide detectors ($6,700).

The building has experienced several concerning issues over its history. In 2023, there were complaints about potential structural problems regarding a center supporting wall. A violation notice in March 2023 cited safety concerns including handrail repairs and the need for smoke detectors. A heating problem in 2012 resulted in tenant complaints about inadequate heat. The property has also had multiple fire safety-related incidents, including three fire complaints between 2006-2013, though most were resolved with corrections made. All recent work permits and violations have been addressed and marked as complete, though there was a complaint in 2023 regarding unpermitted work in the laundry room that was quickly investigated and closed.

Risk rating

How 662-666 Green 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 362 buildings in this neighborhood, 279 are predicted to be safer.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Moderate concern 38.1%
Severe concern 39.5%
