Initial analysis

The 6-story, 36-unit multi-family residential building at 1233 California Street, constructed in 1924 and currently owned by William Canizales Qtip Trust, has experienced several significant maintenance and safety issues over its history. Most recently, in 2023-2024, the building underwent substantial fire safety upgrades, including updating the fire alarm system to meet current code requirements and addressing multiple fire code violations. This followed a serious structural concern in 2017 when moderate settling was reported in the southwest corner at the basement level, affecting clay partitions, brick separation, and common stairways. The building has a documented history of fire safety violations, with multiple citations from 2018 through 2024 regarding emergency lighting, alarm system maintenance, and sleeping area requirements.

The property has undergone various infrastructure improvements, including a 200-amp electrical upgrade in 2022 and significant repairs in 2017 following a Notice of Violation related to safety concerns. Building maintenance records show attention to various systems, including plumbing (replacement of storage tank in 2008) and previous fire safety issues that have been addressed. Several routine inspections and violations have been documented over the years, though most have been resolved. Recent 311 calls from 2024-2025 primarily relate to exterior issues such as sidewalk defects and graffiti, rather than building safety concerns. While the building has faced numerous compliance challenges, recent efforts indicate ongoing maintenance and upgrading of critical systems, particularly focusing on fire safety and structural integrity.

Risk rating

How 1233 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
28th percentile

Out of 448 buildings in this neighborhood, 323 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 6.0%
Moderate concern 77.4%
Severe concern 16.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
