Initial analysis

The two-unit residential building at 161-163 San Carlos Street in the Inner Mission, owned by Brian A. Delbove, is a one-story flats and duplex structure built in 1906. The property has undergone several significant modifications over the years, with the most notable change occurring in 2009 when permits were issued to convert the two-unit building into a three-unit structure. This conversion included removing the staircase that connected the upstairs and downstairs units and adding a kitchen to the downstairs unit, though the project was completed with a reported cost of $15,800. Earlier modifications included a kitchen and bathroom remodel in 2004, though this permit expired, and the removal of a bedroom and kitchen from the ground floor in 1989 was completed.

In recent months (2024-2025), there has been a pattern of street cleaning issues in the vicinity of the building, with multiple reports (seven in total) regarding garbage and debris, including instances of yard waste and other loose materials. There have also been three documented cases of sidewalk parking violations in late 2024, all resulting in citations. Additionally, a basement unit (designated as 163A) was found to have operated as an unauthorized Airbnb rental from fall 2013, though this investigation was ultimately closed with no violation found. The building has experienced one documented fire incident, though it was minor and related to a malfunctioning alarm system with no civilian injuries reported.

Risk rating

How 161-163 San Carlos 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 2380 buildings in this neighborhood, 1404 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.

Neighborhood (ZIP code)

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

12-Month severity forecast
No violation 51.2%
Moderate concern 24.8%
Severe concern 24.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
