Initial analysis

The three-story multi-family residential building at 755-763 Union Street, located in San Francisco's North Beach neighborhood, is a 5-unit structure built in 1907, currently owned by Timothy Lee and Elsie Huang. The building has undergone several significant improvements over the years, with the most recent major upgrade being a complete electrical system overhaul in July 2024, replacing old knob and tube wiring throughout multiple living spaces. In September 2020, a solar panel system was installed, demonstrating the owners' commitment to modernizing the property. The building has maintained its structural integrity through various improvements, including reroofing projects completed in 2013 (cost: $22,310) and 1992, top-floor apartment merging in 1999, and foundation upgrades in 1999.

The property experienced several building violations in late 2005, primarily related to fire safety and security, including issues with smoke detectors, door viewers, and smoke enclosure door closers, though all were promptly abated by January 2006. While there have been routine housing inspections in 1999, 2005, 2008, and 2011, there are no active violations on record. Recent 311 calls indicate ongoing concerns with parking enforcement around the property, with multiple reports of driveway blocking between 2023 and 2024, resulting in several citations being issued. Building maintenance issues appear to be addressed promptly, as evidenced by quick resolution times for various service requests, including a recent tree maintenance issue in 2023. The property's record demonstrates regular upkeep and modernization efforts, with particular attention paid to electrical safety and sustainability features like solar power.

Risk rating

How 755-763 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
33th percentile

Out of 362 buildings in this neighborhood, 243 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 33.9%
Moderate concern 23.6%
Severe concern 42.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
