Initial analysis

The 19 Moss Street property, owned by the William Curry Living Trust, is a two-story multi-family residential building constructed in 1923, containing 4 units in the South of Market neighborhood. Recent concerning events include a significant incident in January 2023 involving hallway ceiling collapse attributed to water damage, with mentions of asbestos, gas leaks, and mold throughout the unit. The building has a notable history of safety and maintenance issues, particularly evident in the 2003-2004 period when multiple violations were recorded, including problems with stairway storage, guardrails, fire safety equipment, and smoke detectors, though these were all officially abated by April 2004. More recent fire safety concerns have been documented, with three violations between 2021-2024 related to alarm systems and sprinkler systems, though these were either corrected or resolved through violation issuance.

The building's recent history has shown recurring maintenance challenges, as evidenced by multiple 311 calls in 2024 reporting issues such as sewage backup, garbage and debris problems, and encampments in the vicinity, with some calls specifically noting human waste or urine in the area. Fire department responses to the building have been primarily for non-fire-related incidents, including elevator rescues, false alarms, and service-related calls, with no civilian injuries recorded in any of these responses. In addition to the documented fire violations, the building has experienced various service and infrastructure-related issues, including a 2023 violation regarding sprinkler system maintenance (noted at a different address, 1049-1053 Howard Street). The property has also undergone several routine safety inspections over the years, with the most recent inspection activity occurring in 2024.

Risk rating

How 19 Moss 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 430 buildings in this neighborhood, 241 are predicted to be safer.
