Initial analysis

The 334-340 Vallejo Street property is a three-story, 6-unit multi-family residential building located in Telegraph Hill, owned by Greg Giachino and constructed in 1909. The building has undergone significant renovations and improvements over the past decade, with several major systems upgraded between 2011-2015, including comprehensive electrical rewiring of multiple units (most notably unit 338A in 2013), complete plumbing system overhauls including new bathrooms and kitchen installations, and HVAC improvements with new furnaces and ducts. A notable soft-story concern was identified in 2017 but was resolved by 2020, and the building received necessary approvals for extending rear stairs to the roof, though this project experienced some delays and required multiple permits to complete.

The building's maintenance history shows a pattern of addressing both routine and urgent repairs, with immediate attention given to plumbing issues, including multiple leaky pipe complaints from 2008-2009. A cluster of building violations was documented in late 2003 related to safety and maintenance matters, including repairs needed for doors, fire extinguishers, and security features, all of which were abated by September 2004. Recent records from 2024 show recurring issues with blocked sidewalks due to scooters, though these are external to the building itself. The property has had regular inspections and permit completions, with minimal unresolved issues, though there were some expired permits from 2017-2019 that required subsequent follow-up permits to obtain final inspections. The building's fire safety systems have been periodically reviewed, with one notable complaint in 2015 regarding sprinkler systems, but this was resolved within a year.

Risk rating

How 334-340 Vallejo 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
24th percentile

Out of 684 buildings in this neighborhood, 520 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.

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 61.4%
Moderate concern 19.8%
Severe concern 18.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
