Initial analysis

The property at 405-411 Duncan Street in Noe Valley is a two-story, four-unit multi-family residential building constructed in 1908, currently owned by Salo Rawet. The building has undergone several significant structural and maintenance improvements over the past two decades, most notably foundation replacement in 2003 ($35,000), installation of a complete electrical system with individual meters in 2003 ($10,050), and various deck repairs in recent years. The property has experienced recurring issues with deck maintenance, with multiple dry rot repairs conducted in both 2023 and 2024 on the rear upper and lower decks, raising concerns about structural integrity. Recent building complaints from November 2023 suggest unauthorized expansion of deck areas beyond the scope of permitted dry rot repairs. The property has also faced challenges related to a retaining wall project, with multiple complaints filed in 2021-2022 regarding discrepancies between approved plans and actual construction, including concerns about drainage, structural support, and property line setbacks.

The building's maintenance history shows regular upkeep, including electrical and plumbing upgrades in 2012, and various repairs to common areas. Historical violations from 2000 regarding gas meter safety requirements were promptly addressed within two months of filing. Recent concerns primarily focus on deck repairs and retaining wall construction, with several complaints filed by neighbors regarding potential safety and code compliance issues. The property has experienced typical urban residential issues as evidenced by 311 calls, mostly related to parking enforcement and routine maintenance matters. Two routine housing inspections in 2001 and 2008 showed no significant problems. While the building has undergone numerous repairs and improvements over the years, the recurring nature of deck-related issues and recent complaints about unauthorized modifications suggest potential concerns about maintenance oversight and compliance with building codes.

Risk rating

How 405-411 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.
