Initial analysis

The 5-unit, 2-story multi-family residential building at 3181-3187 San Jose Ave in the Outer Mission neighborhood, owned by Guido & Pierina Giosso Family, has undergone significant improvements and faced multiple challenges since its construction in 1929. The property is currently classified as a "Soft Story Tier 3 - Non-Compliant" building, with an active violation for failing to file mandatory seismic retrofit work despite a $100,000 retrofit permit being issued in September 2022. Recent major renovations include the ongoing conversion of unit 3185 involving substantial modifications ($68,000) including a bathroom addition and kitchen relocation, along with simultaneous utilities upgrades in 2024 including new ductwork, plumbing, and electrical systems ($68,000). The building has experienced several maintenance and compliance issues over the years, including a 2022 complaint regarding unpermitted water heater installation, multiple heating and plumbing violations from 2005, and various safety-related violations in the early 2000s. Recent improvements appear focused on modernizing the building systems and addressing previous deficiencies, with substantial investment in electrical upgrades including a 400-amp service upgrade and proper gas meter relocation to the garage (cost: $8,000). The property has also seen comprehensive foundation work, including a replacement slab at the ground floor unit, indicating significant structural maintenance efforts. While there have been numerous 311 calls regarding sanitation and parking issues in recent months, these appear to primarily relate to street conditions rather than building-specific concerns.

Risk rating

How 3181-3187 San Jose Ave'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 112 buildings in this neighborhood, 13 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.

NOV rate, owner's portfolio

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

Neighborhood location

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

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 71.9%
Moderate concern 10.4%
Severe concern 17.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
