Initial analysis

The property at 1419 12th Avenue in the Inner Sunset is a three-story, two-unit multi-family residential building constructed in 1947, currently owned by the Law Family Trust. The building has experienced several significant issues over its history, most notably in 2002 when illegal construction work was completed at the ground floor garage area, including the installation of new dividing walls to create additional rooms, along with unauthorized electrical work. This situation led to multiple building violations and fines, though the matter was ultimately resolved in February 2004 after the completion of proper permits and inspections costing approximately $18,000. More recently, a serious maintenance issue has emerged, with a tenant filing a complaint in September 2023 regarding persistent mold problems in the bathroom sink and water leaks around the bathtub, which have reportedly been ongoing since 2019. The building's maintenance record shows some attention to infrastructure updates, including an electrical upgrade in 2003 and a plumbing permit from 2015 for house trap replacement.

The property has also generated multiple 311 calls over the years, primarily related to tree maintenance issues in 2015 and 2016, though these were generally resolved through proper channels. There have been several reports of abandoned vehicles near the property between 2009 and 2016, though all were resolved quickly when the vehicles were found to be gone upon inspection. While there have been no active building violations since 2004, the recent water-related maintenance issues suggest some concerns about the building's current upkeep.

Risk rating

How 1419 12Th 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.

DBI Complaint May 26
I am submitting this formal complaint regarding the ongoing dangerous and unsanitary conditions caused by the resident at 1421 and the apparent failure of her family and responsible caregivers to properly manage and supervise her condition. the resident frequently trespasses onto neighboring properties and searches through all surrounding trash bins, collecting garbage and discarded items from the neighborhood. she then stores or dumps trash, furniture, and other debris around the building and directly in front of my entrance sidewalk and safety exit. these actions have created severe health, sanitation, and safety hazards for residents. the accumulated trash and illegal dumping have caused persistent foul odors, attracted rats, flies, and pests, and contaminated the garage and common areas. the blocked entrance and exit pathways also create a serious fire and emergency evacuation hazard. my family, especially my children, are being exposed daily to unsafe and unhealthy living cond
