Initial analysis

The two-unit residential building at 2354-2356 Bay Street in San Francisco's Marina neighborhood is a two-story flats and duplex structure built in 1929, currently owned by Mauro Tognoni. The building's documented permit history indicates some structural improvements made in early 1990, including the installation of fireproof sheet rock in the garage (though this permit expired) and the completion of foundation bolting and plywood reinforcement at the exterior walls, which were successfully completed and passed final inspection.

More recent activity around the property is particularly notable for 2025, when there were multiple reports of garbage and debris on the street (eight complaints between January and September), though these were generally resolved promptly. There are two open tree-related issues from January 2025, involving a damaged tree and a hanging limb. The property has experienced recurring issues with sidewalk parking between March and April 2024, with seven complaints filed about a black Toyota vehicle, though enforcement officers were unable to validate the complaints in each instance. A fire complaint from September 2016 is recorded in the system, though it was referred to another agency with an unspecified disposition.

Risk rating

How 2354-2356 Bay 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
