Initial analysis

Located in Nob Hill, the three-unit multi-family residential building at 1278-1282 California St was constructed in 1909 and is managed by Nakosone & Hu Revoc Lvg Tr. The building has undergone several significant improvements over the past two decades, with the most substantial work occurring between 2010-2011. This period saw a major $350,000 voluntary structural strengthening project completed in 2010, followed by interior work in 2011 including removal of loose plaster and electrical upgrades. The building received comprehensive electrical system improvements in 2008, including new wiring for all units and a service upgrade to 400A main with 100A per unit. Previous issues from 2005-2009 regarding water seepage, window problems, and insulation concerns were addressed and resolved, including roof door and exterior stair railing repairs. The property underwent routine housing inspections in 2001, 1999, and most recently in 2016, with no active violations on record.

Recent history of the surrounding area includes several 311 calls between 2020-2022 primarily related to street cleaning and sanitation issues, though these are external to the building itself and are not indicative of building condition. The most recent building permit activity was recorded in 2011, focusing on electrical work and structural modifications. While there have been no building permits issued since 2011, the substantial upgrades completed during the 2008-2011 period addressed critical systems including electrical, plumbing, and structural elements. The property remains classified as a three-story flats & duplex building, consistent with its original design.

Risk rating

How 1278-1282 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
