Initial analysis

The 5-story, 4-unit multi-family residential building at 1040 Baker Street in Anza Vista, owned by Michael Anthony Won Lvg Tr, has been standing since 1963 and has undergone several significant maintenance and improvement projects over the years. Most recently, in October 2023, dry rot repairs were completed in the lightwell and around various windows, representing the latest in a series of moisture-related maintenance issues that have persisted since at least 2002, when dry rot was documented in multiple locations including bathrooms and decks. The building has undergone two major roofing projects in 2008-2009 (totaling approximately $30,200), and in 2011, the foundation received attention with an underpinning project costing $20,000. A solar installation was completed in 2008, consisting of 22 roof-mounted PV modules with a total rating of 4.35kW.

The building's history includes several housing code violations and compliance issues, though most of these were resolved promptly. In September 2002, violations related to fire safety and security (fire extinguishers and self-closing doors) were documented but abated by November 2002. More recently, in 2019, there was a complaint regarding unpermitted work on a driveway and fire exit concerns, though this was noted as not active. The property has experienced recurring issues with dry rot across various building elements, including lightwells, garage doors, and windows, with the most recent repairs in 2023 costing $6,500. Outside the building structure itself, the property has seen multiple parking-related complaints in 2024, primarily concerning blocked driveways, though these are external to the building's direct management concerns. Recent service calls have addressed various issues including a missing sewer vent cover (December 2023) and reports of graffiti (November and September 2023), though in at least one instance, no graffiti was found upon inspection.

Risk rating

How 1040 Baker 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
54th percentile

Out of 136 buildings in this neighborhood, 63 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.

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.

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 71.0%
Moderate concern 20.7%
Severe concern 8.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
