Initial analysis

The 4-unit, 2-story multi-family residential building at 537 Duncan Street in Noe Valley, owned by Artal Family LP, was constructed in 1959 and has undergone several significant maintenance and repair projects over the years. Most recently, in October 2023, the building received repairs for dry rot on exterior siding ($5,000), completed an underground service conversion with 200A service and 8 meters in 2006, and underwent a reroofing project in 2002 ($11,000). The building experienced multiple violations in May 2001 related to fire safety and building maintenance, including issues with fire extinguishers, deck repairs, and egress obstructions, though all these violations were abated by June 15, 2001.

More recent concerns include a 2022 complaint about construction noise and rooftop music, and several sewer-related issues with vent problems documented in 2019-2020. The property has also experienced recurring parking enforcement issues, with multiple citations for driveway blocking reported between 2019 and 2022. The most recent building-related inspection complaint was filed in September 2024, though the details of its resolution are not yet fully documented. While the building has experienced various maintenance and regulatory challenges over its history, recent records show ongoing attention to building maintenance, particularly with the exterior siding repairs completed in 2023.

Risk rating

How 537 Duncan 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.
