Initial analysis

The Edna J Rosellini Family Trust owns this two-unit multi-family residential building located at 122 Arbor Street in Glen Park, which was constructed in 1911 as a two-story flats and duplex structure. The building's documented history shows relatively minimal major maintenance work, with the only significant repair being a reroofing project undertaken in September 2008 at a cost of $4,500. The most recent period of record (2023-2024) shows a significant number of street-related issues, particularly in late 2024, with multiple reports of parking violations including driveway blockages and abandoned vehicles. There were also several municipal service requests regarding street defects, vegetation issues, and illegal postings. Two fire-related incidents were recorded in the mid-2000s, both of which were false alarms with no injuries or damage reported, though there was one documented fire violation regarding combustible vegetation near the structure in 2005.

The property has experienced consistent street-level challenges over the past year, particularly concerning parking and transportation issues, with multiple enforcement calls and requests for service still marked as open in late 2024. These external issues appear to be the most significant ongoing concerns for the property based on the available records, while the building's internal systems and structure have shown relatively stable maintenance history, with no major fire safety violations noted in recent years. The property's documented history suggests that while the building itself has remained generally well-maintained, there are ongoing challenges related to street parking and municipal infrastructure in the surrounding area that may impact resident experience.

Risk rating

How 122 Arbor 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
54th percentile

Out of 364 buildings in this neighborhood, 167 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

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 83.1%
Moderate concern 10.4%
Severe concern 6.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
