Initial analysis

This four-story multi-family residential building, located at 1946-1948 California Street in Pacific Heights, was constructed in 1948 and contains two units. The property, currently owned by the McCollum Family Revocable Trust, has undergone significant renovations and improvements over the past two decades. Major recent work includes a substantial renovation project commenced in 2021 (valued at $440,000) that involved installing an elevator, bathroom remodels, and sound isolation improvements on all floors. This was followed by the addition of solar panels in 2022 and further modifications to various floors. In 2023, the building completed a compliance inspection (CC-8618) which required minimal work. The building has undergone important safety upgrades, including the installation of a complete residential fire sprinkler system in 2007, and comprehensive plumbing work including water line replacement in 2020 and bathroom renovations in 2007.

The property has experienced several maintenance and compliance issues over its history, though most have been resolved. Past complaints include unauthorized structural work and various violations in 2002-2007, which have since been addressed. The building's recent history shows active maintenance and upgrades, particularly focused on accessibility improvements (elevator installation), seismic upgrades, and modernization of unit features. Three plumbing permits were required for compliance with a 2023 inspection, indicating a need for continued attention to building systems. The property has also experienced minor external issues, including tree maintenance concerns and occasional waste management violations, though these are typical for urban properties and have been addressed when reported.

Risk rating

How 1946-1948 California 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.
