Initial analysis

The four-unit multi-family residential building at 100-118 Tocoloma Avenue in Little Hollywood, owned by Guido & Pierina Giosso Family, has experienced several notable issues since its construction in 1947. A cluster of building violations in late 2004 centered around window repairs and lead paint concerns, with multiple notice of violation (NOV) letters issued between November 2004 and February 2005, culminating in referrals to City Attorney and a director hearing in April 2005. These violations were ultimately abated by June 2007. The building also had water service installation issues in late 2004, with violations for unpermitted work and undersized piping, which were similarly resolved by mid-2007.

More recent history includes several fire safety incidents, with documented violations in July 2020 for improper storage of combustibles, though this was marked as abated shortly thereafter. The property experienced three fire-related calls between 2006 and 2020, including a gas leak and unintentional alarms, with no civilian injuries reported in any incidents. The building has faced ongoing challenges with street conditions in the surrounding area, as evidenced by multiple 311 calls in late 2024 and early 2025 regarding garbage and debris, though these external issues do not directly impact the building's internal conditions. The violations from 2004-2007 suggest past maintenance challenges, but the resolution of these issues indicates improved compliance with building regulations, though no recent building violation data is available to confirm current conditions.

Risk rating

How 100-118 Tocoloma 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
0th percentile

Out of 7 buildings in this neighborhood, 7 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 44.6%
Moderate concern 23.4%
Severe concern 32.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
