Initial analysis

This two-unit multi-family residential building, located at 1566 19th Street in Potrero Hill, was built in 1911 and is currently owned by the Neill Sullivan Trust. The property has undergone numerous renovations and faced several compliance issues over the years. Most recently, in 2024, comprehensive bathroom remodeling work was completed on both floors, including plumbing and electrical updates. A significant violation occurred in 2021 when a complaint investigation revealed unauthorized conversion of the duplex into a single-family home, with removal of interior demising walls and conversion of the lower unit kitchen into a laundry room. This led to subsequent restoration work in 2021 to reconnect the demising walls and reinstall kitchen appliances to comply with a Notice of Violation. The building has undergone various improvements, including a 2022 system upgrade with a new high-efficiency boiler and radiant floor heating, and a completed garage roof replacement in 2012.

The property has experienced multiple permit-related issues, particularly in 2012, when several complaints were filed regarding unauthorized work and permit violations during renovation projects, including concerns about asbestos siding removal. These violations were eventually abated, though they required increased oversight and multiple permit revisions. Recent improvements include the installation of exterior gas lines for an outdoor BBQ and fire pit in 2024, along with associated landscaping modifications. The building's maintenance history shows regular attention to plumbing, electrical, and structural systems, with the most recent major work focused on updating bathroom facilities and resolving historical compliance issues. Recent maintenance has also included attention to exterior elements and safety concerns, with work completed in response to various violations and complaints, demonstrating ongoing efforts to maintain building compliance and resident safety.

Risk rating

How 1566 19Th 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.
