Initial analysis

The 2-story, 3-unit multi-family residential building at 1883-1887 Union Street in Cow Hollow, owned by Hagop & Nazarethian, has a history of regular maintenance and recent activity suggesting ongoing improvements. Most notably, a significant tenant improvement project valued at $120,000 was issued in November 2024, focusing on accessibility upgrades and interior modifications. The building underwent substantial renovations in 2005, including retail tenant improvements ($80,000) with new partitions, flooring, HVAC installation, and electrical rewiring. The property has seen regular maintenance with reroofing projects completed in 1999 and 2014, and plumbing upgrades including a water main installation in 2016.

Recent months have shown a pattern of street-level sanitation concerns, with multiple reports of overflowing city garbage cans between November 2024 and January 2025, though these are municipal issues rather than building-specific problems. The property is currently in compliance with the city's Formula Retail Thresholds regulation, with clarification obtained regarding Conditional Use Authorization requirements. A single, non-injury smoke detector activation incident was recorded, though no fire was involved. While there was a tenant buyout recorded at a different property address (2814 Laguna Street) in 2021, this does not directly relate to the Union Street building. The most recent building permit activity and 311 calls indicates active property management, with most maintenance and improvement work being properly permitted and completed.

Risk rating

How 1883-1887 Union 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 861 buildings in this neighborhood, 430 are predicted to be safer.
