Initial analysis

The property at 430-432 Balboa Street is a two-unit, two-story duplex built in 1905 located in San Francisco's Inner Richmond neighborhood. The building experienced a significant fire event in 2007 that led to substantial damage and safety concerns, with reports of unsecured top floor windows. In response to the fire, extensive reconstruction and safety improvements were undertaken between 2009-2010, including the installation of a comprehensive fire sprinkler system ($12,000) with 40 sprinklers and monitoring equipment, along with major interior renovations. The building underwent considerable expansion work in 2009, including the addition of a new dwelling unit with two bathrooms and two bedrooms on the third floor, along with interior remodeling on the second floor that added three bedrooms and one bathroom, and updated kitchen and bathroom facilities. During this period, there were several permit revisions and inspections, including changes to stair designs and foundation work.

More recent history shows regular maintenance and compliance activities, with various permits for electrical work, plumbing updates, and general repairs. The property has been subject to routine municipal observations and complaints regarding street-level issues such as illegal postings, sidewalk conditions, and noise, with the most recent being in 2024. These external issues generally relate to street maintenance and public space conditions rather than building safety or habitability concerns. A notable shared spaces violation from 2023 regarding ADA accessibility and structural concerns was still open as of the last reporting date. The building has maintained active compliance status since the major repairs and improvements completed in 2010, with no recent building violations or major internal issues recorded.

Risk rating

How 430-432 Balboa 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
58th percentile

Out of 1723 buildings in this neighborhood, 724 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.

Estimated permit spend (past 7 years)

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

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 81.5%
Moderate concern 12.8%
Severe concern 5.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
