Initial analysis

The property at 1958-1962 Union Street in Cow Hollow is a two-story multi-family residential building with three units, owned by Antonio & Rita Castellucci and dating back to 1909. The building has undergone several significant modifications over the past decade, most notably a proposed ground floor remodel in 2016 intended to change the use from utility to mercantile occupancy, including structural upgrades, new accessible entrance, and fire sprinklers, though this permit remains in "filed" status as of 2023. Other completed work includes a roof replacement in 2012, sewer line and house trap replacement in 2011, and the addition of an address to the rear building in 2015. The property has experienced multiple compliance issues, particularly in 2015-2017, with several complaints filed regarding unauthorized unit conversions and construction work, though these issues were not actively pursued to resolution. Recent history shows regular concerns with street maintenance, parking violations, and noise complaints, with multiple 311 calls in 2023-2024 related to garbage, driveway blocking, and excessive noise. The property has received planning approval for accessory massage use to the personal service and health service use on the first floor, which is permitted within the Union Street Neighborhood Commercial Zoning District.

Risk rating

How 1958-1962 Union 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.
