Initial analysis

The two-unit residential building at 46-48 Service Street in Cow Hollow, owned by the Alexandra C Norkin Trust-20, was constructed in 1961 and has undergone several significant renovations over the years. Most notably, in 2020, the building received substantial upgrades including the replacement of four vinyl windows with aluminum windows in bedrooms to comply with a physical inspection requirement, reroofing of the flat roof area, and various electrical and plumbing corrections. These improvements followed a prior major renovation in 2003-2005 that involved remodeling both kitchens and bathrooms, electrical rewiring, and structural modifications, though some of those permits ultimately expired.

The property has experienced recurring fire safety violations in recent years, with the most recent issues documented in October 2023 and January 2024, including problems with sprinklers/standpipe systems, extinguishers, and sleeping area requirements. While some of these violations were corrected promptly, there are currently open violations requiring attention. The building's maintenance history includes regular upkeep of common systems, such as a Jacuzzi tub repair in 2006, electrical panel relocation, and safety upgrades. The property has faced occasional neighborhood issues typical of urban settings, as evidenced by various 311 calls between 2008-2019 regarding street cleaning, graffiti, and pavement defects, but these are not directly related to the building's condition or safety. Notably, there was a historical incident involving illegal short-term rentals through Airbnb that was subsequently resolved.

Risk rating

How 46-48 Service 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

Out of 861 buildings in this neighborhood, 95 are predicted to be safer.
