Initial analysis

The 10-unit, 2-story multi-family residential building at 186-198 Duncan Street in Noe Valley, owned by Lalena P Goard Lvg Tr, was constructed in 1911 and has undergone several significant improvements in recent years. Most notably, the building completed mandatory seismic retrofitting of its soft-story structure in 2017 (Tier 3), achieving Certification of Completion. Recent safety improvements include the installation of a comprehensive fire safety system in 2020, featuring new control panels, smoke detectors, and emergency pull stations throughout the building, as well as water heater strapping and pipeline repairs in December 2023. The property has also seen substantial unit improvements, including a $100,000 renovation in 2019 of one unit's kitchen and bathrooms, along with electrical and plumbing upgrades.

The building has a documented history of maintenance issues, particularly in the early 2000s, when multiple violations were recorded regarding sanitation, security, and interior maintenance, though these were all abated by 2000. More recent complaints in 2023 raised concerns about stair construction and egress obstruction, though these were marked as not active by March 2024. Several roofing projects have been undertaken, including a $10,000 reroofing job in 2022 and a $19,500 project in 2020. The property has experienced some infrastructure challenges, including plumbing leakage issues in 2010 that affected a neighboring property, though these were promptly addressed. Recent external issues documented through 311 calls include multiple reports of garbage and debris on the property, though these are external to the building itself. The building successfully completed its soft-story retrofit requirements, with supporting documents showing compliance with seismic safety standards, and has undergone various maintenance and improvement works to address both safety and comfort features for residents.

Risk rating

How 186-198 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

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.
