Initial analysis

The three-story multi-family residential building at 526-528 Green Street in Telegraph Hill, owned by Mark & Debra Sondini 2011 T, was constructed in 1908 and contains 5 units plus commercial space. The property has undergone several significant repairs and improvements over the years, with the most recent substantial work being the installation of a wireless doorbell and accessibility sign in 2022, and an electrical panel upgrade in 2020. Of particular note, the building experienced fire-related incidents in 2003 that required major repairs, including roof framing replacement ($17,000) and interior fire damage restoration ($5,000). The property has a history of fire safety violations, with multiple citations in 2002 related to fire escape maintenance, smoke enclosure doors, sprinkler systems, and fire extinguisher requirements, though all were abated by October 18, 2002.

Recent maintenance and safety-related work includes plumbing updates in 2010 involving sink replacements and pipe work, and various electrical improvements. The building has experienced several routine inspections over the years, with the most recent major activities focused on accessibility improvements and fire safety compliance. More recently, there have been multiple 311 calls related to sidewalk cleanliness and waste removal in late 2023, as well as some graffiti issues in 2024, though these are primarily external urban maintenance matters rather than building-specific concerns. The most recent fire alarm-related incidents have all been due to system malfunctions or unintentional activations, with no civilian injuries reported.

Risk rating

How 526-528 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 684 buildings in this neighborhood, 335 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 50.7%
Moderate concern 26.0%
Severe concern 23.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
