Initial analysis

Located in San Francisco's Bernal Heights neighborhood, this 2-unit, 2-story multi-family residential building at 121-123 Saint Marys Avenue was constructed in 1907 and is currently owned by the Carmen Bruni Revocable Trust 20. The property has undergone numerous significant renovations and compliance efforts over the past two decades, including recent work in 2021 to replace approximately 1,900 square feet of wood siding with James Hardie composite siding on the rear of the building at a cost of $51,200, and the 2020 legalization of previously unpermitted rooms on the ground floor, which involved removing an existing kitchen range and hood and was associated with a cost of $84,778.

The building has undergone substantial electrical upgrades, including a 125-amp service upgrade and extensive garage and common area improvements in 2013, along with earlier electrical work in 2004 that included installation of multiple circuits, panels, and fixtures throughout the property. Major structural improvements have included a vertical and horizontal addition completed in 2002, replacing existing rear deck and adding approximately 275 square feet to each unit, as well as comprehensive garage and storage area improvements in 2005-2011 involving new slabs, driveway, and entry steps. The property has maintained reasonable compliance with building codes, though there have been some enforcement actions requiring the legalization of unauthorized modifications. Recent activity at the property has primarily consisted of parking-related issues in the vicinity, with multiple 311 calls regarding sidewalk parking and abandoned vehicles between 2020 and 2023, though these are external to the building itself. A 2020 neighborhood complaint about parking problems related to unauthorized units suggests historical concerns about parking availability in the area.

Risk rating

How 121-123 Saint Marys Ave'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
94th percentile

Out of 1276 buildings in this neighborhood, 77 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

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 88.2%
Moderate concern 8.6%
Severe concern 3.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
