Initial analysis

The three-story, five-unit multi-family residential building at 1621-1623 Vallejo Street in Pacific Heights, owned by Juan M Balcazar, has undergone several renovations since its construction in 1900. The property has a documented history of water-related issues, with notable concerns about moisture and mold, particularly in the period from 2009-2012, when there were multiple complaints regarding leaks and water damage affecting ceilings and various rooms. These issues appear to have been addressed, as indicated by the lack of recent water-related complaints. The building has seen consistent maintenance and improvements, with numerous renovation projects between 2002-2007, including front facade work, window replacement, and multiple kitchen remodels across different units, one of which in 2005 involved electrical upgrades (12 lights, 5 switches, 10 receptacles, 3 circuits).

The property has experienced various maintenance and safety issues over the years, including a fire code violation in 2022 that was corrected by February 2023, and a brief period in 2002 when there was a fire egress obstruction that was resolved within two months. More recent concerns have primarily related to external issues, with multiple 311 calls in 2024 regarding street conditions, including reports of garbage, debris, and noise, though these are not directly related to the building's internal conditions and many have been resolved. The most recent building permit activity was in 2007, and while there have been no major violations or complaints in the past decade, the age of the building and its maintenance history suggest ongoing attention to upkeep is necessary.

Risk rating

How 1621-1623 Vallejo 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

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 31.2%
Moderate concern 13.7%
Severe concern 55.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
