Initial analysis

The 27-unit apartment building at 235 Oak Street in Hayes Valley, owned by Artal Living Trust, is a three-story structure built in 1911 that has undergone several significant improvements and faced various maintenance challenges over the years. Most notably, in 2015 the building completed mandatory soft-story structural upgrading work, which included installing shearwalls and grade beams, bringing it into compliance with seismic safety requirements. The building has recently undergone substantial electrical upgrades, with all units receiving new Siemens panels in May 2024, following a 2019 water line replacement. The property has experienced recurring issues with its fire safety systems, including violations and inspections in 2019 for alarm systems, sprinkler/standpipe systems, and electrical systems, though these violations have since been abated.

Historical records from the building show various maintenance and compliance challenges, particularly in the early 2000s, including multiple housing code violations in 2002 related to fire safety, security requirements, and smoke enclosure systems, all of which were abated by May 2002. There was also a sequence of building complaints in 2003-2004 regarding plumbing, electrical, and kitchen issues, along with unauthorized construction work. More recent concerns have primarily focused on common area maintenance, with multiple 311 calls in late 2024 regarding garbage, debris, and sidewalk issues. The building's maintenance history shows a pattern of addressing major systems through periodic upgrades, including kitchen renovations in the early 2000s and roof work in the late 1980s, though some historical permits from the 1980s are noted as expired. The property is classified as a Tier 2 soft-story building, with these seismic improvements having been completed and certified.

Risk rating

How 235 Oak 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 1027 buildings in this neighborhood, 945 are predicted to be safer.
