Initial analysis

The three-unit, three-story multi-family residential building at 150 20th Avenue, owned by the Henry & Carole Lee Family Trust, was constructed in 1986 following the demolition of a previous structure. The property has undergone several significant improvements over the years, with the most substantial being a comprehensive 2020 renovation that replaced all windows with fiberglass units and upgraded the exterior siding, including both horizontal siding and shingle options, at a cost of $210,000. Prior to this, the building received a new roof in 2008, demonstrating regular maintenance of core infrastructure elements.

The building's recent history from 2018 to present has been marked primarily by parking-related incidents, particularly during 2020 when there were multiple reports of illegal parking, including double parking and vehicles blocking driveways. Between 2018 and 2023, there were several parking enforcement actions taken, with varying degrees of resolution, though most recent incidents have occurred outside the building's immediate vicinity. The property appears to be generally well-maintained from a structural perspective, with no building permits or violations recorded in recent years that would indicate significant maintenance issues or safety concerns. The most recent building improvement permits date back to 2020, suggesting this was a major upgrade period for the property.

Risk rating

How 150 20Th 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.
