Augrented Insights

Initial analysis

The building at 4320-4330 California Street is a 7-unit, 3-story multi-family residential property constructed in 1914, currently owned by Talmage Bypass Tr. The property has undergone several significant maintenance and upgrade projects in recent years, most notably a reroofing project in April 2024 costing $26,850. The building completed its soft-story seismic retrofit requirements, achieving CFC status, and underwent accessibility improvements in 2016 when the steel frame was revised to a special steel moment frame. Mechanical systems have received attention, with a gas main repair for units 2 and 3 completed in 2018 and HVAC upgrades including a new forced air furnace and condenser installation in 2016.

The property has a documented history of addressing both preventive and corrective maintenance, including multiple permit renewals in 2021 for previously approved work that required final inspection. In terms of resident safety and comfort, there was a notable incident in 2014 involving reported mold in a bedroom potentially linked to roof leaks, though this complaint is listed as not active. The surrounding area has experienced typical urban maintenance issues as recorded in 311 calls, primarily relating to street cleaning and graffiti, with the most recent service calls addressing general cleaning needs in October 2023 and a damaged tree report from February 2024. While there have been three false fire alarms recorded, none resulted in civilian injuries. The building's compliance history shows regular attention to necessary repairs and improvements, with most recent work focusing on exterior maintenance and structural integrity through the completion of its soft-story retrofit requirements.

Risk rating

How 4320-4330 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

10th percentile

Out of 660 buildings in this neighborhood, 594 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.

Building size

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

Number of units

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast

No violation 45.8%

Moderate concern 40.0%

Severe concern 14.2%

Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
