Initial analysis

The two-unit residential building at 3137-3139 Steiner Street in Cow Hollow is a two-story flats and duplex structure built in 1907, currently owned by the Massucco Family Survivors Trust. The property has undergone several significant improvements over the past three decades, with its most notable recent upgrade being the installation of 17 energy-efficient vinyl windows in 2006, featuring double-pane construction with a U-factor of .30, completed at a cost of $5,985. Earlier renovations in 2003 addressed multiple areas, including bathroom electrical work (E200302033493) to install lighting, exhaust fan, GFCI receptacle, and kitchen wiring for appliances, along with bathroom improvements including sheetrock work, closet wall modifications, dry rot repairs, and plumbing fixture updates costing $20,000. The building has also received important structural enhancements, including foundation work in 1991 with the installation of a concrete cap and secure bolting of mudsills to improve seismic safety.

The property has experienced relatively few maintenance issues over its history, though there is currently an open maintenance issue reported in October 2021 regarding a damaged tree with reported vandalism. The building's permit history suggests regular maintenance and modernization efforts by the ownership, with no recorded building code violations or safety concerns in the available data. The most recent substantial improvements were made in the mid-2000s, focusing on energy efficiency and general upkeep, while earlier structural work in the early 1990s addressed foundational stabilization.

Risk rating

How 3137-3139 Steiner 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 861 buildings in this neighborhood, 310 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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood location

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 69.7%
Moderate concern 13.2%
Severe concern 17.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
