Initial analysis

The two-unit residential building at 1072 Alabama Street in San Francisco's Inner Mission neighborhood is a 2-story flats and duplex structure built in 1900, currently owned by the Knorr-class 2013 Revocable Trust. The property has undergone several significant renovations over the years, with the most substantial recent work filed in March 2022 proposing major additions including front and rear horizontal expansions, a third-floor vertical addition, a new rear deck, spiral stairs, and various interior remodels, with an estimated cost of $1,255,000. This follows earlier improvements including a 2009-2011 project to convert garage storage space into accessible loft space, a 2003 rear porch repair due to rot, and kitchen and bathroom remodeling work from 1997.

The building's recent history shows consistent attention to maintenance and upgrades, particularly in the electrical systems, with permits issued in 2012 and 2003 for electrical work related to the various renovations. In the past three years (2021-2024), there have been multiple reports regarding sidewalk parking violations near the property, with seven documented cases, though most were promptly addressed by parking enforcement. The surrounding area has experienced some infrastructure issues, particularly with a tree root-lifted sidewalk (reported December 2024), and there have been occasional concerns regarding street cleanliness (2021). The property appears to be in active use with ongoing maintenance and development projects, as evidenced by the recent major addition proposal and the historical record of systematic improvements and repairs.

Risk rating

How 1072 Alabama 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
99th percentile

Out of 2380 buildings in this neighborhood, 24 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.

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 85.2%
Moderate concern 11.6%
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.
