Initial analysis

This three-story, six-unit multi-family residential building located at 1-11 Lilac Street in the Inner Mission, owned by Kathryn & Peter Van Der Zee, was constructed in 1890 and has undergone several significant modifications and faced numerous maintenance challenges over the years. Most notably, the building completed a mandatory soft-story retrofit in 2018 (cost: $30,000), bringing it into compliance with seismic safety requirements. Recent housing quality concerns have emerged in 2023, particularly affecting Unit #3, with multiple complaints regarding water intrusion, mold, rodent problems, and unauthorized construction work. The building has a history of plumbing issues, with repairs documented in 2009, and several building violations were addressed in early 2004, including deficiencies related to fire safety, security, and sanitation.

The property has experienced recurring issues with its exterior maintenance and infrastructure systems, including siding repairs in 2008 (following tree damage), weatherproofing work in 1997, and various plumbing updates between 2004-2009. The building has been the subject of multiple fire safety inspections, with three exit blockage complaints between 2022 and 2023, though most were found to have no merit or were corrected promptly. Recent 311 calls in early 2025 have primarily concerned exterior issues such as garbage and debris removal, though these are municipal sidewalk cleaning matters rather than building-specific problems. The property received approval for a Cottage Food Operation under Sec. 209.4 in 2024, indicating some form of commercial activity is now permitted on-site.

Risk rating

How 1-11 Lilac 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.

Neighborhood percentile

Out of 2380 buildings in this neighborhood, 1833 are predicted to be safer.
