Initial analysis

The 12-unit multi-family residential building at 444-446 Warren Drive in Forest Knolls, owned by Clifford & Bernice Wong 199, is a two-story structure built in 1961 that has undergone several significant improvements over the past decade. Most notably, the building completed mandatory soft-story seismic retrofitting in 2014 (at a cost of $40,000), which included foundation reinforcement, anchor sill bolting, and the installation of steel rigid moment frames at the garage door opening. Recent maintenance includes a comprehensive re-roofing project in 2018 ($14,950) and plumbing upgrades such as the replacement of the house sewer line and street trap in 2020. The building has experienced routine housing inspections in 2023, 2018, and 2009, with no significant violations noted in recent years.

While the building has maintained compliance with safety requirements since the resolution of several fire-related violations in 2003, there have been four notable fire department responses to the building in recent years, all of which were non-emergency situations involving either alarm system activations, elevator rescues, or smoke detector issues - with no civilian injuries reported in any incidents. A 2020 complaint regarding COVID-19 safety compliance during exterior painting was filed but subsequently closed. The property has experienced ongoing issues with debris management, as evidenced by multiple Recology street cleaning requests in 2024, though these appear to be external to the building itself. Recent complaints also indicate some challenges with parking management around the property, including sidewalk blocking and driveway access issues reported in 2023.

Risk rating

How 444-446 Warren Dr'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
10th percentile

Out of 50 buildings in this neighborhood, 45 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.

Neighborhood location

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

12-Month severity forecast
No violation 20.1%
Moderate concern 18.1%
Severe concern 61.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
