Initial analysis

The two-unit residential building at 472-474 Connecticut Street in Potrero Hill is a two-story flats/duplex structure built in 1900 and currently owned by Gerald W. Guay. The property has undergone several significant improvements over the past three decades, most notably a substantial rear addition project in 2010-2011 that included kitchen expansion, new deck construction, and associated electrical and gas installations, with costs totaling over $25,000. The building's maintenance history includes important infrastructure updates such as a sewer lateral replacement in 2022 and a cleanout/back-up prevention device installation in 2014, though the 2022 sewer-related incident suggests some lingering plumbing challenges. Earlier improvements included skylight installations in 2002, various interior modifications in the late 1990s (including kitchen cabinet and window replacements), and a re-roofing project in 1999.

The property's recent activity records (2018-2023) show primarily municipal service calls, with some concerns about illegal parking in the vicinity and a few maintenance matters such as general cleaning and tree maintenance. The building's permit and planning records indicate careful attention to structural and functional improvements, including rear yard variances and deck modifications to enhance living space. The most recent substantial work on record relates to the 2022 sewer infrastructure upgrade, while earlier improvements have focused on modernizing and expanding the living space. While the building has maintained active compliance with necessary permits and inspections, the relatively recent sewer issues suggest that plumbing infrastructure remains an area requiring periodic attention.

Risk rating

How 472-474 Connecticut 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
64th percentile

Out of 726 buildings in this neighborhood, 261 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.

Neighborhood location

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

Building age

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

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

12-Month severity forecast
No violation 77.6%
Moderate concern 17.3%
Severe concern 5.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
