Initial analysis

The 21-unit, 3-story apartment building at 1301 California Street, owned by Acd Investments Lp and constructed in 1910, has undergone significant recent improvements and faced several challenges. Most notably, the building is currently non-compliant with Tier 2 soft-story retrofit requirements, though a retrofit permit was issued in April 2024 with an associated cost of $70,000. Recent renovations include foundation work, retaining wall repairs, and a new fire alarm system installation in 2023-2024, demonstrating ongoing infrastructure maintenance. The property has experienced serious heating system issues, with multiple complaints about no heat in December 2022 and February 2023, and a current active maintenance complaint from November 2024.

The building has a history of multiple unit upgrades, including several kitchen remodels (notably Unit 2 in 2024, and Units 9 and 17 in 2023), bathroom improvements, and various plumbing system updates including boiler replacements in 2014. While many building violations have been resolved over the years, there is a concerning pattern of fire safety issues, with recent violations in 2023 related to the alarm system that have since been corrected. Historical complaints include concerns about plumbing systems (2020), window replacements without proper permits (2012), and electrical violations (2011). The building's management has been actively addressing improvement requirements, as evidenced by numerous completed permits for various building systems and unit upgrades, though there are still several active compliance issues related to building code requirements.

Risk rating

How 1301 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.

Neighborhood percentile

Out of 448 buildings in this neighborhood, 336 are predicted to be safer.
