Initial analysis

The 4-unit multi-family residential building at 829-833 Vallejo Street in North Beach, owned by Kenneth K W Szeto, is a three-story flats and duplex structure dating back to 1908. The building has undergone several significant improvements, most notably a comprehensive solar panel installation project in 2013 that included multiple phases with a total output capacity of 8.5 kW, along with electrical upgrades to support the system. Roofing work has been a recurring theme in the building's maintenance history, with major projects completed in 1998 and 2013, while a proposed window replacement in 2016 was cancelled. The property experienced a rodent and insect infestation issue in April 2019 that warranted involvement from the Department of Public Health's Environmental Health division.

The building's external environment has faced various challenges, including recurring issues with loose garbage in the vicinity, with multiple reports between 2019 and 2022. There was a documented incident of graffiti on the building in October 2016, which was addressed within days. Parking-related complaints were recorded in 2018, and street cleaning concerns were raised in 2016 regarding an overflowing city garbage can. A smoke detector malfunction was recorded as a fire incident, though there were no civilian injuries reported. The property's maintenance record shows regular upkeep of essential systems, particularly focusing on sustainable energy improvements through the installation of solar panels, while also addressing basic residential infrastructure needs such as roofing and window maintenance.

Risk rating

How 829-833 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
56th percentile

Out of 362 buildings in this neighborhood, 159 are predicted to be safer.

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.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

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 39.6%
Moderate concern 17.5%
Severe concern 42.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
