Initial analysis

The three-unit multi-family residential building at 1676 Union Street in Cow Hollow, owned by Guido A & Mary O Alasia Irr, has undergone several significant improvements since its construction in 1965. Most recently, in October 2023, the building received a complete reroofing with modified bitumen, and is currently undergoing the installation of a backflow preventer as of January 2025. The property has a notable history of addressing safety and compliance issues, particularly regarding an unpermitted stair elevator installation in 2008 that led to multiple violations and required enforcement actions, though this was eventually resolved by March 2013. Other major improvements include the 2012 replacement of exterior trim and windows, a 2007 deck replacement project, and the installation of a sewer housetrap in 2016. The building has been the subject of regular routine inspections, with the most recent plumbing work involving a new gas line installation for the water heater in 2010.

The property has maintained an active response to infrastructure and safety needs, as evidenced by recent flood prevention improvements receiving grant funding, including the installation of a backwater valve, trench drain, and cleanable surfaces. While there have been various maintenance and compliance issues documented through 311 calls, these have generally been addressed promptly. Recent exterior maintenance issues include tree maintenance (2024), illegal postings (2023), and occasional noise complaints (2021), though these do not appear to significantly impact the building's overall condition or safety. The building's records demonstrate a consistent pattern of maintenance and upgrades, with most recent improvements focusing on infrastructure and safety systems, including the recent roof replacement and upcoming backflow prevention installation.

Risk rating

How 1676 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
80th percentile

Out of 861 buildings in this neighborhood, 172 are predicted to be safer.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

Building permits, owner's portfolio
