Initial analysis

The property at 728-730 Union Street is a two-unit multi-family residential building located in San Francisco's North Beach neighborhood. Built in 1907, this two-story structure has a documented history of several maintenance and service calls, with the most pressing recent concerns relating to sanitation issues. Between June 2024 and December 2024, there were multiple reports of garbage and debris on or near the property, including instances of furniture and other waste that required intervention from Recology and Public Works Services. The building's historical records show a reroofing project completed in 1990, and two street space permits issued in 2004, though these are relatively minor in comparison to more recent issues.

In terms of municipal planning history, the property has been subject to height restrictions as part of the North Beach - Russian Hill area's zoning regulations, with records showing map amendments to lower the height limit from 65-A to 40-X. These interim controls, established in 1987, affect the overall development potential of the site, though this is historical information that would not directly impact current residents. The property has maintained regular compliance with city regulations, though there have been recurring issues with waste management and street cleanliness in the immediate vicinity, as evidenced by multiple 311 calls throughout 2024. Recent reports in November 2024 included an environmental health complaint, though the outcome was recorded as "Closed Accepted."

Risk rating

How 728-730 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
77th percentile

Out of 362 buildings in this neighborhood, 83 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.

Building age

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

Building permits, owner's portfolio

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 84.4%
Moderate concern 9.6%
Severe concern 5.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
