Initial analysis

The property at 1-7 Imperial Alley in San Francisco's Cow Hollow neighborhood is a two-story, four-unit multi-family residential building constructed in 1906 and currently owned by Roy J Bruna and Thorunn Gudmu. The building has undergone several significant maintenance and infrastructure improvements over the years, including a complete furnace and heating system upgrade in 2009 involving gas lines, flues, and wall heater replacement. A reroofing project was completed in 2000 at a cost of $11,480, and the building was brought into code compliance through a dedicated effort in 1987. The property has faced some safety and maintenance issues, including a fire safety violation in 2008 regarding combustible storage, which was resolved within one month, and a 2011 incident involving improper lead paint containment during work, though this was quickly addressed. The building has undergone routine housing inspections in 1995, 2002, and 2008, all of which were resolved.

In recent years, the property has experienced ongoing challenges with parking enforcement, evidenced by multiple 311 calls between 2023 and 2025 regarding blocked driveways and sidewalk parking. Eight parking-related complaints were filed during this period, with several resulting in citations being issued, though some cases were invalid due to incomplete reporting information. Additionally, there was one report of loose garbage requiring general cleaning in October 2023, which was investigated but found to have no identifiable issues. The concentration of parking violations and the ongoing nature of these complaints suggest a persistent infrastructure challenge in the immediate vicinity, though this is more related to street conditions than the building itself.

Risk rating

How 1-7 Imperial Aly'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
33th percentile

Out of 861 buildings in this neighborhood, 577 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.

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.

12-Month severity forecast
No violation 36.8%
Moderate concern 13.1%
Severe concern 50.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
