Initial analysis

The property at 3660-3662 19th Street in Mission Dolores is a two-story, four-unit multi-family residential building constructed in 1915, currently owned by William Y K & Gloria L Wong. The building has undergone several maintenance and repair works over its lifetime, with the most recent significant work being a complete reroofing project completed in March 2023, costing $18,000. This followed a previous reroofing project from 1997 and a kitchen renovation in 2010. The building has experienced multiple violations and complaints over the years, with the most serious issues occurring in 2002 and 2011. In 2002, multiple fire safety violations were documented, including problems with fire proofing materials and egress obstructions, though these were all abated by February 2002. In 2011, additional fire proofing violations were noted along with concerns about lead paint, weather proofing of siding, and interior painting needs, all of which were subsequently addressed. A more recent issue was reported in March 2024 regarding a broken front window, which was resolved by April 2024.

The building has faced several maintenance challenges over the years, including a significant plumbing incident in 2012 involving repeated sewer backups in the garage, though this was quickly addressed within two days. There were also historical issues with window conditions, water damage, heating systems, and various interior surface problems noted in the 1999 routine inspection. The most recent building concerns relate to a broken window and ongoing issues with garbage and debris management in the vicinity, as evidenced by multiple recent 311 calls between November 2024 and December 2024 regarding abandoned furniture, debris, and general cleaning needs around the property.

Risk rating

How 3660-3662 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.

Neighborhood percentile
39th percentile

Out of 799 buildings in this neighborhood, 487 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 46.7%
Moderate concern 34.6%
Severe concern 18.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
