Initial analysis

1 San Antonio Place is a three-story, 12-unit multi-family residential building constructed in 1961 in Telegraph Hill, currently owned by 1 San Antonio I5 LLC. The property has undergone significant recent renovations, including multiple unit upgrades between 2019 and 2023, focusing on modernizing facilities with washer/dryer installations, kitchen and bathroom rehabilitations, and electrical system improvements. Notably, there was a major safety concern in 2020 when a rockfall incident required slope netting installation at a cost of $100,000. The building has experienced recurring maintenance issues and various violations between 2017-2019, including problems with heating systems, water intrusion, mold, and emergency systems. In 2022, there were complaints about construction debris and noise, and one unit temporarily lacked heat in early 2020. The property underwent a significant fire alarm system upgrade in 2022 to meet current safety codes, following several fire-related complaints between 2017-2018 regarding various safety systems. While most recent permits and violations have been resolved, the building's history includes periods of maintenance challenges, particularly between 2017-2019, when multiple housing code and building system issues were documented.

Risk rating

How 1 San Antonio Pl'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 684 buildings in this neighborhood, 677 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Number of units

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

12-Month severity forecast
No violation 11.0%
Moderate concern 71.5%
Severe concern 17.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
