Initial analysis

This two-unit multi-family residential building, located at 1579-1581 11th Avenue in the Inner Sunset neighborhood, was constructed in 1900 and is currently owned by Sarah Robinson and Paolo Bazzur. The property has undergone several significant maintenance and improvement projects over the past few decades, with the most recent being a reroofing completed in September 2024 at a cost of $21,750. Historical records show substantial renovation work in 2000, including a kitchen and bath remodel, structural modifications involving wall removal and truss installation, and dry rot repairs. Infrastructure improvements include foundation reinforcement with bolts and straps installed in December 1999. The building's plumbing system received attention in 2022 with the replacement of a gas water heater.

The property has experienced various maintenance and regulatory issues over the years, including an unpermitted deck enclosure complaint in 2002 and multiple instances of parking enforcement required for driveway blocking between 2023-2024. Recent service requests include concerns about an overgrown tree near communication lines (September 2024) and public works matters (July 2024). There have been two reports of human or animal waste on the street/sidewalk (October 2023). The building's safety systems include smoke detectors, though one was recorded as having a malfunctioning activation. While most complaints and service requests have been resolved, there are currently three open matters as of October 2023-2024, including excessive noise and tree maintenance concerns.

Risk rating

How 1579-1581 11Th 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

Out of 1493 buildings in this neighborhood, 776 are predicted to be safer.
