Initial analysis

The subject property at 1446 6th Avenue in San Francisco's Inner Sunset district is a two-story, two-unit multi-family residential building constructed in 1922 and currently owned by the Alonso Family Trust. The building's maintenance history shows relatively limited major interventions, with the only building permit on record being for reroofing work completed in 1994.

The property has experienced several infrastructure issues over the past decade, with notable concerns regarding sewer systems. There were two sewage backup incidents reported in December 2012 and December 2015, both involving 4-inch sewer vents, with records indicating they were properly addressed and resolved through PUC Sewer Operations. More recently, in 2020, there was an unspecified fire complaint that was investigated and determined to have no merit. The most recent infrastructure issue was a pothole problem in construction trenches reported and resolved in December 2024. The property has also encountered various municipal service issues in the surrounding area, including a parking enforcement call in 2019, a toter management issue in 2017, and curb defect investigations in 2023, though these were more related to the public right-of-way than the building itself. A manhole cover inspection was conducted in 2016 with no action required, and multiple inspections in 2023 found no significant defects in curbs.

Risk rating

How 1446 6Th 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
