Initial analysis

The 3-story, 4-unit multi-family residential building at 32-34 Alta Street in Telegraph Hill, owned by Robert C Callahan Trustee, has experienced several significant maintenance and safety issues since its construction in 1956. The most concerning recent history includes a plumbing upgrade for gas houseline extension completed in October 2023, and multiple reports of rodent/insect infestations in late 2023. The building faced serious exterior maintenance challenges between 2011-2015, with complaints about weatherproofing and lead paint hazards leading to violation notices and a "blighted property" designation, though these issues were officially abated by July 2015. Two sewage backup incidents were reported in early 2012, and between 2008-2009, there were multiple fire safety violations related to storage in mechanical and electrical rooms, though these were subsequently closed with corrections. Historical records show various construction and improvement work, including a retaining wall installation in 1987, though there have been some permit expirations, such as a 1985 code compliance permit. The building's documented history suggests recurring maintenance issues, particularly regarding exterior upkeep and safety systems, while showing some attention to compliance through various repairs and upgrades over the years.

Risk rating

How 32-34 Alta 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
40th percentile

Out of 684 buildings in this neighborhood, 410 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.

Neighborhood location

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 51.9%
Moderate concern 14.2%
Severe concern 33.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
