Initial analysis

This two-story, three-unit multi-family residential building located at 4104-4106 17th Street in Corona Heights was constructed in 1917 and is owned by Leslie Thompson. The property has undergone several significant improvements over its lifetime, with the most substantial being a $25,000 window replacement project in early 2020, where 12 existing aluminum windows were upgraded to new Marvin wood-clad double-pane units at the front of the building. Historical records show earlier maintenance work including reroofing in 1991, though this permit has since expired.

The building has had two routine housing inspections, one in 2001 and another in 2009-2010, both of which were resolved. More recent attention to the property area has primarily involved external conditions rather than building-specific issues, with multiple 311 calls in late 2024 regarding garbage and debris, including reports of abandoned furniture and needles. There were also several incidents in April 2024 relating to shared spaces and roadway safety, including required signage and crosswalk obstruction issues, which were resolved through contractor intervention. While there was a notable encampment situation reported in August 2023 in the vicinity, it was deemed ADA compliant and no action was taken against the occupants. The building's maintenance record suggests regular upkeep, particularly with the recent window upgrade being the most significant building-specific improvement in recent years.

Risk rating

How 4104-4106 17Th 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.
