Initial analysis

The 6-unit, 2-story multi-family residential building located at 1245 20th Ave in the Central Sunset neighborhood was constructed in 1962 and is currently owned by Ugo I & Loreta Colabianchi. The property has undergone several significant improvements over the past decades, most notably completing a mandatory Soft Story retrofit in 2017 to comply with seismic safety requirements, for which they invested $60,000. Other major maintenance work has included three roofing projects (1992, 2014, and 2017), window and siding replacements in 2009 totaling $11,000, and compliance with various housing inspections.

The building experienced some regulatory challenges, including a Soft Story Retrofit Program violation in 2017, which was ultimately resolved by September 2019 when the retrofit work was completed and a Certificate of Final Completion was issued. While the property has maintained regular housing inspections (2002, 2009, 2014), there were two fire-related incidents worth noting: several fire safety violations in 2002 regarding smoke enclosure door closers that were abated within a month, and a recent fire alarm system complaint in January 2025 that is currently unresolved. The most recent records indicate recurring issues with garbage and debris removal from the property, with multiple reports between November 2024 and January 2025, though these were addressed by Recology and marked as resolved.

Risk rating

How 1245 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.

Neighborhood percentile

Model explanation

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Moderate concern 22.2%
Severe concern 31.4%
