Initial analysis

The four-unit, two-story multi-family residential building at 40-44 Via Ferlinghetti in Telegraph Hill was constructed in 1907 and is currently owned by Sergio M Salvetti. The property has undergone several significant maintenance and improvement projects over the years, with the most recent being a filed permit in September 2024 for the installation of a 19-foot retaining wall to address deteriorated landscaping issues. In 2021, substantial repairs were made to the rear stairway at a cost of $8,000. Historical improvements include a kitchen remodel completed in 2000, reroofing work in 1999, and various interior updates in the late 1980s. The building has maintained compliance with routine housing inspections, with records showing regular monitoring of common areas in 2002, 2005, and 2013.

Recent activity around the property has primarily involved external maintenance and community interactions. In early 2025, a tree pruning request was submitted, and in late 2024, there was a resolved case regarding abandoned property. The building experienced construction-related noise complaints in July and September 2021, though these were linked to nearby restaurant construction rather than work on the property itself. There have been multiple reports of loose garbage and general cleaning issues in the surrounding area between 2021-2022, most of which were determined to be related to the adjacent business rather than the residential building. The property has been subject to routine housing inspections, with no significant violations or recurring issues noted in the available records. Recent parking-related incidents in 2023 were police responses to vehicles blocking driveways and parking spaces, though these were external issues not directly related to the building itself.

Risk rating

How 40-44 Via Ferlinghetti'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

17th percentile

Out of 684 buildings in this neighborhood, 568 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

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 46.7%

Moderate concern 27.7%

Severe concern 25.6%

Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
