Initial analysis

The property at 3955-3957 20th Street, owned by Laval Revocable Trust, is a two-story, four-unit multi-family residential building constructed in 1907 in the Eureka Valley/Dolores Heights neighborhood. The building's maintenance records show significant attention to roofing infrastructure in 2011, with comprehensive work completed including the installation of new plywood and a complete reroofing project costing over $14,000 in total. A documented interior repair from 1998 addressed cracked ceilings in three rooms.

More recently, there has been one building complaint filed in April 2020 regarding non-essential renovations, though this case is currently listed as not active. The property has experienced recurring issues with driveway blocking, particularly between 2021 and 2024, with at least five citations issued and several instances where enforcement officers were unable to locate the offending vehicles. Other recorded incidents include a graffiti report in October 2023 (though this was administratively closed due to technical issues) and a driveway blocking case in September 2023 that was deemed invalid due to incomplete reporting information. While the building's structural maintenance appears to be adequately addressed through historical permits, the location continues to experience persistent challenges with parking enforcement matters, particularly regarding access to the driveway.

Risk rating

How 3955-3957 20Th 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
