Initial analysis

The 7-unit, 3-story multi-family residential building at 432-440 Lombard Street in Telegraph Hill, owned by Castagnola George J Jr, was constructed in 1911 and has undergone several significant improvements over the years. Most notably, the building completed a mandatory soft-story retrofit in 2017 (as a Tier 3 building), which included the installation of prefabricated special moment frames, plywood shear walls, and replacement of brick foundations, all with a $170,000 investment. The property has seen substantial modernization efforts in recent years, including a comprehensive bathroom, kitchen, and living room remodel in 2020 ($50,000), a complete rewiring of one of its units in 2020, and the installation of a new furnace and ducting that same year. Recent safety upgrades include a fire alarm system enhancement filed in July 2023. Historically, the building has maintained good compliance with housing standards, with only routine inspections recorded in 2000, 2004, and 2006 showing no significant issues.

The building's infrastructure maintenance record is robust, showing attention to essential systems such as plumbing and electrical. Notable plumbing work includes sewer replacement from the foundation to city connection in 2010 and various unit-specific upgrades. Safety features have also been addressed, with the replacement of burglar bars with safety releases at eight windows in 1998, window sash replacements, and multiple bathroom remodels throughout the building's history (most recently in 2020). The property has been responsive to infrastructure maintenance needs, as evidenced by prompt addressing of tree damage issues reported in 2018. While there have been occasional neighborhood issues such as parking violations and an abandoned motorcycle report, these are not directly related to the building's condition or management.

Risk rating

How 432-440 Lombard 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

Out of 684 buildings in this neighborhood, 602 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 40.9%
Moderate concern 29.3%
Severe concern 29.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
