Initial analysis

The two-unit multi-family residential building at 3891 25th Street in Noe Valley, owned by Ingrid Marlow Separate prpt, has undergone several significant renovations since its construction in 1900. The most substantial work occurred between 2006-2008, when major improvements were made including foundation repairs, interior remodeling of both units with new kitchens and bathrooms, exterior upgrades with new cement plaster and wood windows, and the installation of new electrical systems with 100-amp services and comprehensive wiring. During this period, the building also received new plumbing throughout, two new furnaces, and modern safety features including six smoke detectors. Earlier improvements from 2001 included the replacement of four front windows with new double-paned units.

The property has experienced recurring issues with driveway access, with multiple citations issued between March 2024 and September 2024 for vehicles blocking the driveway, including incidents involving a Chrysler, Jaguar, Lexus, and Toyota. There are also recent concerns regarding street maintenance, with an open pavement defect report from April 2024, and a resolved issue regarding a damaged tree from April 2024. In 2023, there were complaints about sidewalk blockage from construction equipment and an obstruction in the parking lane that remains unresolved as of September 2023. All other major renovation work performed between 2006 and 2008, including structural, electrical, and plumbing improvements, has been completed or received final inspection approvals, indicating proper adherence to building codes during that period.

Risk rating

How 3891 25Th 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
