Initial analysis

The two-unit residential building at 2947-2949 Laguna Street in Cow Hollow, owned by Frank & Flora Bonsignori Re, is a two-story flats and duplex structure built in 1924. The property has undergone several significant maintenance and improvement projects over the years, with the most recent work completed in August 2023 involving repairs to rotted areas in the exterior lightwell stairs at a cost of $5,000. Other notable historical improvements include electrical system upgrades in 2004 with the installation of a 125-amp main service and two meter sockets, seismic improvements with anchor bolts and plywood walls in 1991, and various envelope improvements in the late 1980s including reroofing, window installations, and vinyl siding application.

The building's recent history has been marked by multiple incidents of parking violations, particularly in early 2023, with several reports of vehicles blocking driveways, some resulting in citations, though enforcement officers were unable to locate the vehicles in several instances. There have also been two instances of abandoned Christmas trees on the property in 2023 and 2024, both of which were resolved through proper pickup services. The building has experienced minimal security or maintenance issues beyond routine upkeep, though there were two graffiti incidents reported in 2023 - one on a mailbox and another in a different location, both of which were addressed by appropriate authorities. The property's maintenance record suggests regular attention to building preservation, with most historical permits showing "Complete" status, indicating successful project completion.

Risk rating

How 2947-2949 Laguna 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.
